Managing patients with an overactive bladder and glaucoma: a questionnaire survey of Japanese urologists on the use of anticholinergics

BJU INTERNATIONAL, Issue 1 2005
Kumiko Kato
OBJECTIVES To establish the views of urologists on the use of anticholinergic drugs for treating the overactive bladder (OAB) in patients with glaucoma. SUBJECTS AND METHODS In February 2004 a self-description questionnaire was mailed to all 417 urologists who were members of the Tokai Society of Voiding Dysfunction, to determine current practice in Japan for patients with an OAB and glaucoma. Subgroups were analysed between the types of practice and the duration since the urologists had graduated from medical school. RESULTS Of the 155 respondents, 76 (49%) routinely enquired about a history of glaucoma before prescribing anticholinergics, and 45 (29%) routinely referred patients with such a history to ophthalmologists. To treat patients with OAB and glaucoma, 102 (66%) would prescribe anticholinergics if permission were available from the ophthalmologist, 33 (21%) chose other treatments and 17 (11%) abandoned treatment. Forty-nine urologists (32%) were currently prescribing anticholinergics to patients with glaucoma. As to knowledge about glaucoma, 132 (85%) urologists knew that there were two types of glaucoma and 98 (63%) knew about laser iridotomy. The proportion of urologists who knew of the two types of glaucoma and asked patients for this information was significantly higher in university than in general hospitals (P < 0.05). CONCLUSIONS Although anticholinergic drugs can precipitate angle-closure glaucoma by pupillary block, they are not contraindicated in open-angle glaucoma or in angle-closure glaucoma that has already been treated by laser iridotomy. Not all urologists are aware of this difference, at least in Japan. Some urologists avoid anticholinergics in all patients with glaucoma, while others pay little attention to glaucoma. Routine history taking and referral to ophthalmologists allows many patients with OAB and glaucoma to benefit safely from anticholinergics. Moreover, clinicians should be aware of patients with OAB who have not been evaluated by ophthalmologists but who are at risk of angle-closure glaucoma. [source]


Major eye diseases and risk factors associated with systemic hypertension in an adult chinese population: the Beijing Eye Study

ACTA OPHTHALMOLOGICA, Issue 2009
T LIBONDI
Purpose To assess the relationship of hypertension with major eye diseases and other ocular parameters. Methods The Beijing Eye Study is a population-based study. Examination at baseline in 2001; follow-up examination in 2006; 3222 subjects had blood pressure measurements. All participants underwent a thourough ophthalmic examination and blood pressure measurement. Hypertension was defined as a systolic blood pressure ,140 mm Hg and/or a diastolic blood pressure ,90 mm Hg, and/or self-reported current treatment for hypertension with antihypertensive medication. Results Mean age of participants in the present study was 60.4±10.0 years. Hypertension was present in 1500 (46.6%) of the 3222 subjects who had their blood pressure measured. In multiple regression analysis, hypertension was associated with higher intraocular pressure (P = 0.005), arterio-venous nicking (P = 0.009),retinal vein occlusions (P = 0.02), and diabetic retinopathy (P = 0.02). Hypertension was not significantly associated with the prevalence of open-angle glaucoma (P = 0.19) or angle-closure glaucoma (P = 0.15), age-related macular degeneration (P = 0.73), nuclear cataract (P = 0.88), posterior subcapsular cataract (P = 0.30), cortical cataract (P = 0.10), or area of alpha zone (P=0.05) or beta zone of parapapillary atrophy (P = 0.95). Conclusion In Chinese persons, while controlling for other systemic parameters, hypertension was associated with increased intraocular pressure, retinal microvascular abnormalities, and prevalence of retinal vein occlusion and diabetic retinopathy. Hypertension was not associated significantly with age-related macular degeneration, age-related cataract, or glaucoma [source]

Abstract. Purpose:, We set out to quantify changes in the anterior chamber volume (ACV), anterior chamber depth (ACD) and anterior chamber angle (ACA) measurements obtained by the Pentacam rotating Scheimpflug camera following uneventful phacoemulsification surgery in normotensive eyes with open iridocorneal angles. Methods:, We enrolled 44 eyes of 44 consecutive patients undergoing cataract extraction in this prospective study. Patients with a history of glaucoma, angle-closure glaucoma or any other concurrent ocular disease were excluded. A detailed eye examination including intraocular pressure (IOP) measurement was performed and ACV, ACD and inferior, superior, temporal and nasal ACA measurements were obtained in each patient eye using the Pentacam Comprehensive Eye Scanner (Pentacam CES) before and 3 months after phacoemulsification and intraocular lens (IOL) implantation with temporal clear corneal incision. Data were compared using paired t -test and one-way anova. Results:, Mean preoperative ACV, ACD, ACA and IOP measurements were 164.7 ± 49.8 mm3, 3.0 ± 0.8 mm, 35.7 ± 10.2 ° and 15.8 ± 3.7 mmHg, respectively. Three months postoperatively, mean ACV, ACD, ACA and IOP measurements were 200.9 ± 33.3 mm3, 3.9 ± 0.9 mm, 41.5 ± 6.5 ° and 13.2 ± 3.9 mmHg, respectively. Postoperative mean ACV, ACD and ACA values in all four quadrants were significantly increased (p < 0.0001, p < 0.0001, p < 0.0001, respectively), whereas IOP was significantly reduced (p < 0.0001). Conclusions:, The Pentacam CES allowed very easy, fast, automatic and non-contact quantification of the anterior chamber parameters pre- and postoperatively in all patient eyes. Measurements obtained confirm that in normotensive eyes with open iridocorneal angles, the ACV and ACD increase and the ACA widens in all quadrants 3 months after uneventful phacoemulsification and IOL implantation. These changes are accompanied by a significant fall in IOP in the short term. [source]

Abstract. Purpose:, This review presents and summarizes the findings of the Beijing Eye Study. Methods:, The Beijing Eye Study is a population-based study which included 4439 of 5324 subjects (aged , 40 years) who were initially examined in 2001. The study was repeated in 2006, when 3251 (73.2% of 4439, or 61.1% of 5324) of the original subjects participated. Participants underwent a series of examinations including: refractometry; pneumotonometry; biomicroscopy assisted by slit-lamp; optical coherence tomography of the anterior segment; photography of the cornea, lens, optic disc, macula and fundus; blood sampling for laboratory tests; blood pressure measurements, and determinations of anthropomorphic parameters. They were also asked to complete a questionnaire which included questions on socioeconomic parameters, and awareness and treatment of ocular and general diseases. Results:, We present normative data for refractive error, anterior segment measurements, intraocular pressure and optic disc structures and their associations, frequency and causes of visual impairment, blindness and visual field defects, prevalences of trachoma, pterygia, open-angle glaucoma and angle-closure glaucoma, cortical, nuclear and posterior subcapsular cataract, age-related macular degeneration, retinal vein occlusions, diabetes mellitus and diabetic retinopathy, myelinated nerve fibres, and retinitis pigmentosa, and associated and risk factors. Discussion:, These data may be helpful for dealing with public health issues in China and for assessing associated and risk factors of ocular and general diseases in general. [source]

Use of latanoprost to reduce acute intraocular pressure rise following neodymium: Yag laser iridotomy

ACTA OPHTHALMOLOGICA, Issue 3 2002
Catherine J. Liu
ABSTRACT. Purpose: To evaluate the efficacy of latanoprost in reducing acute intraocular pressure (IOP) elevation after neodymium:Yag laser iridotomy (LI). Methods: Primary angle-closure glaucoma (PACG) eyes were randomized to receive premedication with latanoprost and pilocarpine or with pilocarpine only before LI. Postoperative IOP changes were compared with Wilcoxon signed-ranks test using the fellow eyes of 47 patients who had one eye in each group. Results: Postoperative pressure spikes were significantly lower (p =,0.010) in the latanoprost group (4.1 ± 5.0 mmHg) than in the control group (6.7 ± 7.0 mmHg). Mean elevation of IOP was less in the latanoprost group than in the control group at 1 hour (2.5 ± 4.8 versus 4.1 ± 4.7 mmHg, p = 0.013) and 2 hours (0.8 ± 5.6 versus 4.4 ± 8.1 mmHg, p = 0.003) postoperatively. Eleven eyes in the latanoprost group (23.4%) and 20 eyes in the control group (42.6%) developed a rise in IOP ,,6 mmHg (p =,0.048). Conclusion: Latanoprost may reduce the pressure rise following LI in PACG eyes, but its application is limited by a late onset of effect. [source]

Posner-Schlossman syndrome (glaucomatocyclitic crisis)

CLINICAL AND EXPERIMENTAL OPTOMETRY, Issue 1 2007
Ralph J Green DipAppSc(Optom)
Posner-Schlossman syndrome (PSS) or glaucomatocyclitic crisis is a rare, typically unilateral recurrent inflammatory ocular hypertensive disease in which diagnosis can be challenging. An acute elevation of intraocular pressure is accompanied by or followed within a few days by a mild, often symptomless uveal inflammation. The mild nature of the uveitis at presentation of the first attack may go undetected. Medical treatment is indicated to prevent pressure-related optic nerve damage and to reduce inflammation. This report details a patient with Posner-Schlossman syndrome whose unilateral pressure elevation was initially treated as acute angle-closure glaucoma. He subsequently had several episodes of increased pressure over a two-year period. Diagnostic difficulties in this case are discussed. [source]
