Surgical treatment of carpal flexural deformity in 72 horses

AUSTRALIAN VETERINARY JOURNAL, Issue 5 2008
RE Charman
Carpal flexural deformities (CFD) are frequently encountered in the horse, with both congenital and acquired forms described. The success of surgical correction of CFD, both in terms of the ability to achieve a straight palmar carpal angle and the impact on future athletic performance, requires further investigation. Objective To report the surgical management and outcome of treatment of flexural deformity of the carpus in 72 horses up to 12 months of age. Method Information was obtained from the medical records of horses surgically treated for CFD and through follow-up contact with owners. At the time of examination each case was graded on the severity of the flexural deformity as grade 1, 2, or 3, in order of ascending severity. Surgical treatment consisted of tenotomy of the ulnaris lateralis and flexor carpi ulnaris muscles. Re-assessment of the palmar carpal angle was made in the immediate postoperative period and again from at least 8 months after surgery via telephone contact with owners and/or breeders. A successful outcome was defined as achievement of a straight palmar carpal angle. Long term outcome was assessed in terms of fulfilment of intended use for horses reaching 3 years of age at the time of the study. Results A total of 135 surgical procedures were performed on 72 horses. A successful outcome was recorded in 111 limbs (82%). Excluding cases lost to follow-up, surgical correction was more successful in restoring a straight palmar carpal angle in grade 1 limbs (25/25, 100%) compared to grade 2 limbs (78/87, 89%) and grade 3 limbs (8/14, 57%). For those horses that had reached 3 years of age, 26 of 36 Thoroughbreds started in a race (72%) and 12 of 14 non-Thoroughbreds fulfilled their intended use (86%). Conclusion Tenotomy of the ulnaris lateralis and flexor carpi ulnaris tendons for treatment of grade 1 and 2 CFD's has an excellent prognosis for restoration of a straight palmar carpal angle and for intended athletic pursuit of the horse. In cases of grade 3 CFD, the prognosis following surgery is guarded, especially in neonates. Horses treated in this study were up to 12 months of age, indicating that this deformity may not always be self-limiting as previously thought, and treatment may be required for successful resolution of flexural deformity of the carpus in older animals. The results of this study will help veterinarians to make recommendations regarding the surgical treatment of CFDs. [source]

The effect of drug eluting stents on cardiovascular events in patients with intermediate lesions and borderline fractional flow reserve,

CATHETERIZATION AND CARDIOVASCULAR INTERVENTIONS, Issue 4 2007
Shahar Lavi MD
Abstract Objective: To assess the role of fractional flow reserve (FFR) in guiding therapy in the drug eluting stent (DES) era. Background: FFR is a useful index for evaluation of the physiological significance of angiographically indeterminate coronary artery lesions. However, its role in the DES era is unknown. Methods: Long term outcome of 281 patients with angiographically indeterminate coronary lesions and borderline FFR (0.75 , FFR < 0.9) was obtained. The outcome of patients who had a DES placed (n = 58), was compared with that of consecutive patients with borderline FFR that were treated by PCI with bare metal stents (BMS, n = 58), or were deferred from revascularization (n = 165). Results: FFR was significantly higher in the deferred group (median and IQR); 0.85 (0.82 to 0.88) compared with the BMS (0.78; 0.76 to 0.82) and the DES (0.79; 0.77 to 0.82), P < 0.001. Pretreatment FFR was a significant determinant of long term event rates in the deferred patients (P = 0.002) but had no effect in patients treated by PCI. In the deferred group, there were fewer events (death, myocardial infarction, target vessel revascularization) compared with the BMS group; but no significant difference was observed between the DES and the deferred groups. Conclusions: In borderline FFR, long term outcome after PCI with BMS is inferior to conservative therapy or PCI with DES. While conservative management is preferable in these patients, PCI with DES may be considered in specific circumstances. © 2007 Wiley-Liss, Inc. [source]

Long term outcome of bleb needling revisions following mitomycin C trabeculectomy in Afro-Caribbean eyes

ACTA OPHTHALMOLOGICA, Issue 2007
TA WILLIAMS
Purpose: To assess the frequency, risk factors and outcome of patients requiring bleb needling revisions (BNR)following Mitomycin-C (MMC) augmented trabeculectomies in Afro-Caribbean eyes in Birmingham, United Kingdom. Methods: ReGAE (Research in Glaucoma and Ethinicity) is a UK based multidisciplinary based research group whose research is aimed at preventing glaucomatous blindness in the diverse ethnic population of the West Midlands. A prospective study of consecutive Afro-Caribbean patients with refractory advanced glaucoma who had undergone Mitomycin C augmented trabeculectomy (modified Cairns type trabeculectomy with fornix based conjunctival flap mitomycin C 0.1-0.4mg/ml) was completed. Bleb needling revisions in the operating theatre with subconjunctival 5 fluro-uracil (5FU) 0.1ml 25mg/ml) were required in a subset of eyes. The frequency, timing, complications and outcome of BNRs was studied. Results: 38 eyes (35 patients) were included in the study; mean age 52 years (range 11-77 years); male:female 21:14. 9 of 38 eyes (24%)required BNR. Aetiology of glaucoma POAG 44%; JOAG 23%; traumatic 11%; fuchs 11%; pseudoexfoliation 11%. Of the patients requring BNR 6 eyes required BNR within 1 month of MMC- trabeculectomy. BNRs were performed 1-48 months postopereratively. Number of BNRs required 1.7 per eye (range 1-4) over a 2 year post operative follow up period. No complications occurred during BNR. Conclusions: Afro-Caribbean patients have a significant risk of requiring BNR following MMC trabeculectomy. Although such bleb manipulations are most commonly required during the early postoperative period, late subtenon's fibrosis may necessitate late BNR in this ethnic group. [source]

Objective To review the short and long term outcomes among singleton infants with breech presentation at term delivered in a geographically defined population over a 10-year period. Design Retrospective, cohort study. Setting District General Hospital. Population 1433 term breech infants alive at the onset of labour and born between January 1991 and December 2000. Methods Data abstracted from birth registers, neonatal discharge summaries and the child health database system were used to compare the short and long term outcomes of singleton term breech infants born by two different modes of delivery (prelabour caesarean section and vaginal or caesarean section in labour). Fisher's exact test was used to compare the categorical variables. Main outcome measures Short term outcomes: perinatal mortality, Apgar scores, admission to the neonatal unit, birth trauma and neonatal convulsions. Long term outcomes: deaths during infancy, cerebral palsy, long term morbidity (development of special needs and special educational needs). Results Of 1433 singleton term infants in breech presentation at onset of labour, 881 (61.5%) were delivered vaginally or by caesarean section in labour and 552 (38.5%) were born by prelabour caesarean section. There were three (0.3%) non-malformed perinatal deaths among infants born by vaginal delivery or caesarean section in labour compared with none in the prelabour caesarean section cohort. Compared with infants born by prelabour caesarean section, those delivered vaginally or by caesarean section in labour were significantly more likely to have low 5-minute Apgar scores (0.9%vs 5.9%, P < 0.0001) and require admission to the neonatal unit (1.6%vs 4%, P= 0.0119). However, there was no significant difference in the long term morbidity between the two groups (5.3% in the vaginal/caesarean section in labour group vs 3.8% in the prelabour caesarean group, P= 0.26); no difference in rates of cerebral palsy; and none of the eight infant deaths were related to the mode of delivery. Conclusions Vaginal breech delivery or caesarean section in labour was associated with a small but unequivocal increase in the short term mortality and morbidity. However, the long term outcome was not influenced by the mode of delivery. [source]

Angioplasty and stenting of symptomatic and asymptomatic vertebral artery stenosis: to treat or not to treat

EUROPEAN JOURNAL OF NEUROLOGY, Issue 2 2010
V. Parkhutik
Background and purpose:, Comprehensive indications for treatment of symptomatic vertebral stenosis remain unavailable. Even less is known about endovascular treatment of asymptomatic cases. We treated symptomatic and asymptomatic vertebral ostium stenosis with angioplasty and stenting and investigated the long term outcome. Methods:, Consecutive patients with two different indications were included. Group 1 (G1) had symptomatic >50% stenosis. Group 2 (G2) had asymptomatic >50% stenosis and severe lesions of anterior circulation and were expected to benefit from additional cerebral blood supply. Results:, Twenty nine vertebral origin stenoses in 28 patients (75% men, mean age 64 ± 9 years) were treated. There were 16 G1 and 13 G2 cases. Technical success rate was 100%. Immediate neurological complications rate was 3.4% (one G1 patient with vertebral TIA due to release of emboli). Two further strokes were seen during follow up (32 ± 24 months): vertebrobasilar stroke in a G2 patient with permeable stent in V1 segment, new ipsilateral V3 occlusion and high-risk cardioembolic source, and carotid stroke in a G1 patient who had had ipsilateral carotid stenting. There were no deaths of any cause. Asymptomatic restenosis was observed in one out of 19 patients from both groups who underwent a follow up angiography. Conclusions:, Angioplasty and stenting appears to be technically feasible and safe in asymptomatic and symptomatic vertebral stenosis. More studies are needed in order to clarify its role in primary and secondary prevention of vertebrobasilar stroke. High risk anterior circulation lesions should be taken into account as a possible indication in patients with asymptomatic vertebral stenosis. [source]

Screening for fetal alcohol syndrome: is it feasible and necessary?

ADDICTION BIOLOGY, Issue 2 2000
Larry Burd
The potential to utilize screening strategies to improve the identification and outcome of persons with fetal alcohol syndrome (FAS) is reviewed. FAS is a condition where screening and surveillance activities would be appropriate. Development of FAS screening and surveillance programs is encouraged because the disorder is expensive. People with FAS have poor outcomes as adults with less than 10% living independently. Several useful tools and models are available. Screening would improve ascertainment and prevalence estimates. Early identification could improve access to services and long term outcome, secondary disabilities and, by extension, excess disability in affected children could be decreased. Lastly, mothers who are at the highest risk to have additional children with FAS could be identified and offered treatment. While both screening and surveillance activities are discussed, the principle focus of this article is a review of the screening process. Two screening tools and several screening methodologies for FAS are available. Since no test will be appropriate in all settings, screening tests need to be selected depending on the setting and population of interest. Screening for FAS should be conducted in a variety of settings and in populations of both high and moderate risk. The results would also provide important data to influence public policy development and resource allocation. Appropriate evaluation of the efficacy, efficiency and effectiveness of FAS screening tools and methodologies would be important before utilization in screening programs. [source]

Pediatr Transplantation 2010:14:276,282. © 2009 John Wiley & Sons A/S. Abstract:, We aim to report a single center experience of the management and long term outcome of HPS in pediatric liver transplant recipients. A retrospective review of children with HPS from 1990 to 2004. Inclusion criteria: liver disease or portal hypertension, hypoxemia (PaO2 < 70 mmHg or SaO2 < 95%) and intrapulmonary shunting documented by macroaggregated albumin scan ratio of >4% (classified mild group [<20%], moderate group [20,40%] and severe group [>40%]). Resolution of HPS post-liver transplant was defined as PaO2 > 70 mmHg or SaO2 > 95%. Eighteen children (six male [34%], median age at diagnosis of HPS 8.6 [1,15.5] yr) had HPS: biliary atresia (n = 8), idiopathic biliary cirrhosis (n = 4), progressive intrahepatic cholestasis (n = 2), miscellaneous (n = 4). The majority had mild shunting (n = 8). Fourteen underwent transplantation with resolution of HPS in 13. Six developed complications: hepatic artery thrombosis (n = 4), biliary (n = 2). Four children died (28%), two pretransplant. There was a tendency towards shunt fraction worsening to a slower degree over time. One-yr survival rate post-transplant was 93%. Median PaO2 was significantly lower in non-survivors compared to survivors (43 vs. 55.2 mmHg, p = 0.03). There was correlation between oxygen parameters pretransplant and time to HPS resolution post-transplant. HPS is reversible after transplant, but is associated with increasing mortality and morbidity. [source]

Objective Assessment of long term outcome following laparoscopic sacrocolpopexy. Design Retrospective follow up study using standardised examination with pelvic organ prolapse quantification system (POP-Q) and questionnaires. Setting A tertiary urogynaecology unit in the North West of England. Population One hundred and forty consecutive cases who had a laparoscopic sacrocolpopexy at St Mary's Hospital, Manchester, between 1993 and 1999. Methods Women completed questionnaires and were examined in gynaecology clinic or sent postal questionnaires if unable to attend the clinic. Main outcome measures Adequacy of vault support and recurrent vaginal prolapse assessed by POP-Q score. Assessment of prolapse, urinary and bowel symptoms and sexual function using questionnaires. Results One hundred and three women were contacted after a median of 66 months. Sixty-six women were examined and a further 37 women filled in questionnaires only. Recurrent vault prolapse occurred in 4 of the 66 women who were examined. Prolapse had recurred or persisted in 21 of 66 women, with equal numbers of anterior and posterior vaginal wall prolapse. Overall, 81/102 (79%) said that their symptoms of prolapse were ,cured' or ,improved'; 39/103 (38%) still had symptoms of prolapse. For every two women who were cured of their urinary or bowel symptoms, one woman developed worse symptoms. Conclusions Among the 66 women available for examination laparoscopic sacrocolpopexy provided good long term support of the vault in 92%. Forty-two percent of these women had recurrent vaginal wall prolapse. Despite this, 79% of women felt that their symptoms of prolapse were cured or improved following surgery. [source]

Lactate dehydrogenase predicts hypoxic ischaemic encephalopathy in newborn infants: a preliminary study

ACTA PAEDIATRICA, Issue 8 2010
Mathias Karlsson
Abstract Background:, Enzyme leakage as a result of hypoxia-ischaemia induced cell damage in affected organs is seen together with hypoxic ischaemic encephalopathy (HIE) after perinatal asphyxia. Aim:, To investigate whether plasma lactate dehydrogenase [LDH], alanine aminotransferase [ALT] and aspartate aminotransferase [AST] during the first 12 h after birth predict HIE and adverse neurodevelopment outcome in newborn term infants with intra-partum signs of foetal distress. Methods:, Enzymes were measured within 12 h post partum in newborn infants with differing degree of HIE (n = 41) and in infants with signs of foetal distress during birth (n = 205) without HIE (non-HIE group). All infants were randomized into two groups. One group (n = 123) was used for calculation of cut off limits for the enzymes studied and the other group (n = 123) was used for calculation of the predictive value of the enzymes for detection of HIE. Results:, Using ROC curves, a cut off level of 1049 U/L for [LDH] was the best predictor of HIE (sensitivity 100% and specificity 97%) but also for long term outcome after HIE. Conclusion: [LDH] is a good predictor of HIE during the first 12 h after birth. This result is of clinical interest offering a potential inexpensive and safe prognostic marker in newborn infants with perinatal asphyxia. [source]

Resuscitation at the limits of viability , an Irish perspective

ACTA PAEDIATRICA, Issue 9 2009
RA Khan
Abstract Background:, Advances in neonatal care continue to lower the limit of viability. Decision making in this grey zone remains a challenging process. Objective:, To explore the opinions of healthcare providers on resuscitation and outcome in the less than 28-week preterm newborn. Design/Methods:, An anonymous postal questionnaire was sent to health care providers working in maternity units in the Republic of Ireland. Questions related to neonatal management of the extreme preterm infant, and estimated survival and long-term outcome. Results:, The response rate was 55% (74% obstetricians and 70% neonatologists). Less than 1% would advocate resuscitation at 22 weeks, 10% of health care providers advocate resuscitation at 23 weeks gestation, 80% of all health care providers would resuscitate at 24 weeks gestation. 20% of all health care providers would advocate cessation of resuscitation efforts on 22,25 weeks gestation at 5 min of age. 65% of Neonatologists and 54% trainees in Paediatrics would cease resuscitation at 10 min of age. Obstetricians were more pessimistic about survival and long term outcome in newborns delivered between 23 and 27 weeks when compared with neonatologists. This difference was also observed in trainees in paediatrics and obstetrics. Conclusion:, Neonatologists, trainees in paediatrics and neonatal nurses are generally more optimistic about outcome than their counterparts in obstetrical care and this is reflected in a greater willingness to provide resuscitation efforts at the limits of viability.

Long term follow-up of transcatheter coil embolotherapy for major colonic haemorrhage

COLORECTAL DISEASE, Issue 10 2010
T. M. Ahmed
Abstract Aim, Therapeutic angiography with embolization is fast becoming the preferred treatment modality for major bleeding in the lower gastrointestinal (LGI) tract. The aim of this study was to determine the long term outcome and complications of percutaneous coil embolization (PCE) and its efficacy as definitive therapy in patients with major LGI bleeding. Methods, All patients presenting to our institution with a haemodynamically significant LGI tract bleed between 1995 and 2001 that were unresponsive to conservative measures were considered for emergency angiography and coil embolization where appropriate. The outcome of these individuals was determined by case note review and telephone interview. Results, There were 20 patients (11 females) with a mean follow-up period 72 months, mean age was 67 years. All underwent PCE following positive angiogram. The most common site of bleeding was the right colon (40%); haemostasis was successfully achieved in 16 (80%) patients. Five of the 20 patients died within 30 days of the intervention, three following PCE and two following surgery. None of the mortality following PCE was considered procedure related. On long term follow-up four patients required readmission to hospital for further LGI bleeds at 1, 2, 12 and 16 months respectively. Ischaemic complications occurred in 23%. Conclusion, Superselective embolization as the primary technique for the treatment of haemodynamically significant LGI bleeding is an effective, feasible and safe technique. Long term follow-up in our series up to 72 months has shown that it should be considered as both a primary and potentially definitive treatment for life threatening LGI bleeds. [source]

Extended surgery for local recurrence and advanced rectal cancer

COLORECTAL DISEASE, Issue 2006
P. M. Sagar
Abstract Although much effort has been directed at reducing the incidence of local recurrence after surgical resection of rectal cancer, there remain a significant number of patients who will develop local recurrence without evidence of metastatic disease. Such patients, as well as patients with locally advanced rectal cancer at presentation, may represent a surgical challenge. Application of sound surgical principals and team work can lead to a good long term outcome. This paper sets out to discuss the philosophy and techniques involved in the surgical management of such patients. [source]

Stage I seminoma: What should a practicing uro-oncologist do in 2009?

INTERNATIONAL JOURNAL OF UROLOGY, Issue 6 2009
Julia Skliarenko
Abstract Testicular tumors are uncommon, but they continue to represent an important group of malignancies in young men. It is the most common solid malignancy in males between the ages of 20 and 35, and primary germ cell tumors are the most common histological type. In the United States in 2008, approximately 4800 cases of seminoma, approximately 4100 of which were stage I disease were projected after the completion of staging investigations. Remarkable progress has been made in the treatment of testicular seminoma over the past 25 years. Management options of stage I seminoma include radiotherapy, surveillance, or adjuvant chemotherapy. Standard management until recent years has been adjuvant retroperitoneal radiotherapy. Although providing excellent long term results, this approach has been associated with increased risk of gonadal toxicity, development of secondary malignancies and an increased risk of cardiovascular disease. The use of surveillance in management of patients with stage I seminoma is therefore becoming more frequent as it minimizes the burden of treatment and maintains the cure rate at virtually 100%. Adjuvant chemotherapy using Carboplatin has been investigated as an alternative management approach. However, the long term outcomes of patients managed with Carboplatin are not yet clear and this strategy should only be used in a study setting. It has been suggested that more patients with stage I seminoma will die of their treatment than of their cancer; therefore, the thrust of modern management should be to maintain 100% cure while minimizing the burden of treatment.

A meta-analysis of the prospective randomised trials of coronary revascularisation before noncardiac vascular surgery with attention to the type of coronary revascularisation performed

ANAESTHESIA, Issue 10 2009
B. M. Biccard
Summary Prospective randomised trials of coronary revascularisation prior to noncardiac surgery have shown no survival benefit following noncardiac surgery. However, these studies have not differentiated the outcomes associated with coronary artery bypass grafting (CABG) and percutaneous coronary interventions. We performed a meta-analysis of the randomised controlled trials of pre-operative coronary revascularisation for noncardiac surgery, extracting data for 30 day and long term all-cause mortality and myocardial infarction (MI) following revascularisation, according to the type of revascularisation performed. Pre-operative percutaneous coronary intervention was associated with significantly increased 30 day MI and composite death and MI. Pre-operative CABG was associated with a significantly improved long term composite outcome of death and MI compared to percutaneous coronary interventions. The adverse effect of percutaneous coronary interventions on both short and long term outcomes in vascular surgical patients should be taken into consideration when interpreting these trials. CABG may improve long term outcomes in vascular surgical patients. The indications for and timing of CABG in vascular surgical patients needs further research. [source]

Improved survival with drug-eluting stent implantation in comparison with bare metal stent in patients with severe left ventricular dysfunction

CATHETERIZATION AND CARDIOVASCULAR INTERVENTIONS, Issue 3 2006
FACC, Giuseppe Gioia MD
Abstract OBJECTIVE: We examined the efficacy of drug-eluting stent (DES) implantation (Sirolimus or Paclitaxel) in patients with ischemic cardiomyopathy and severe left ventricular (LV) dysfunction and compared the outcome with a similar group of patients undergoing bare metal stent (BMS) implantation. BACKGROUND: Patients with severe LV dysfunction are a high risk group. DES may improve the long term outcomes compared with BMS. METHODS: One hundred and ninety one patients (23% women) with severe LV dysfunction (LV ejection fraction ,35%) underwent coronary stent implantation between May 2002 and May 2005 and were available for follow-up. One hundred and twenty eight patients received DES (Sirolimus in 72 and Paclitaxel in 54) and 63 patients had BMS. Patients with acute S-T elevation myocardial infarction (STEMI) were excluded. The primary endpoint was cardiovascular mortality. A composite endpoint of major adverse cardiac events (MACE) including cardiovascular mortality, myocardial infarction (MI), and target vessel revascularization (TVR) was the secondary endpoint. RESULTS: Mean follow-up was 420 ± 271 days. No differences were noted in age (69 ± 10 years vs. 70 ± 10 years, P = NS), number of vessel disease (2.3 ± 0.7 vs. 2.2 ± 0.8, P = NS), history of congestive heart failure (47% vs. 46%, P = NS), MI (60% vs. 61%, P = NS), or number of treated vessels (1.3 ± 0.5 vs. 1.3 ± 0.6, P = NS) for the DES and BMS group, respectively. Diabetes was more common among DES patients (45% vs. 25%, P = 0.01). The left ventricular ejection fraction (LVEF) was similar between the two groups (28% ± 6% vs. 26% ± 8%, P = NS for the DES and BMS, respectively). During the follow-up, there were a total of 25 deaths of which two were cancer related (2 in DES group). There were 23 cardiac deaths, 8/126 (6%) which occurred in the DES group and 15/63 (24%) in the BMS group (P = 0.05 by log-rank test). MACE rate was 10% for the DES group and 41% for the BMS group (P = 0.003). NYHA class improved in both groups (from 2.5 ± 0.8 to 1.7 ± 0.8 in DES and from 2 ± 0.8 to 1.4 ± 0.7 in the BMS, P = NS). CONCLUSION: Compared with bare-metal stents, DES implantation reduces mortality and MACE in high risk patients with severe left ventricular dysfunction. © 2006 Wiley-Liss, Inc. [source]

4233: Outcomes of the Boston Keratoprosthesis Type II

ACTA OPHTHALMOLOGICA, Issue 2010
J CHODOSH
Purpose To report the long term outcomes of Boston keratoprosthesis type II implantation in the management of severe ocular surface disease and corneal blindness. Methods A retrospective review of medical records of patients after Boston keratoprosthesis type II implantation at the Massachusetts Eye and Ear Infirmary from January, 1, 2000 through December 31, 2009. Main outcome measures included visual acuity, device retention, and postoperative complications. Results A total of 29 eyes of 26 patients received a Boston keratoprosthesis type II during the study period. Operated patients had corneal blindness due to mucous membrane pemphigoid (51.7%), Stevens Johnson syndrome/toxic epidermal necrolysis (41.4%), or other ocular surface disease (6.9%). Visual acuity after surgery improved to at least 20/200 in 23 eyes (79.3%), and to 20/30 or better in 10 eyes (34.5%). In patients with at least 1 year of follow-up (n=21), visual acuity of 20/200 or better was maintained in 14 eyes (66.7%). Of these 14 eyes, 6 eyes (42.9%) retained visual acuity of 20/200 or better for more than 5 years. Overall, visual acuity of 20/200 or better was maintained for at least 5 years in 6 of 23 eyes (26.0%). Eyes that failed to improve to 20/200 or lost vision during follow-up were found to have end stage glaucoma, previous retinal detachment, or age related macular degeneration. Of the total of 29 eyes, 17 devices (58.6%) were retained without extrusion or replacement during a total follow-up time of 107.9 person-years. Conclusion The Boston keratoprosthesis type II is a viable option for corneal blindness from severe autoimmune ocular surface diseases. Complications require prompt recognition and management to promote retention of the device and preservation of vision. [source]
