Novel mutations in the MYOC/GLC1A gene in a large group of glaucoma patients,,

HUMAN MUTATION, Issue 6 2002
Karin Michels-Rautenstrauss
Abstract Mutations at the myocilin (MYOC) gene within the GLC1A locus have been revealed in 2-4% of patients suffering primary open angle glaucoma (POAG) worldwide. In our ongoing glaucoma study sixhundred eighty two persons have been screend for MYOC mutations. The first group consisted of 453 patients from a long-term clinical study diagnosed either with juvenile OAG (JOAG), POAG, ocular hypertension (OHT) or normal tension glaucoma (NTG) plus 22 cases of secondary glaucoma. This group, and additional 83 healthy controls, is part of a long term study with repeated clinical examinations at the University of Erlangen-Nurnberg. An additional sample of 124 glaucoma patients or at risk persons referred from other sources were included in the mutation screening. Five novel mutations, namely Gly434Ser, Asn450Asp, Val251Ala, Ile345Met and Ser393Asn, could be identified as cause of preperimetric POAG, JOAG, normal tension POAG and POAG. Myocilin mutations were identified similar with previous reports with other ethnic populations at the rate of 11/341 (3.2%) probands. © 2002 Wiley-Liss, Inc. [source]

Management of retinoblastoma with proximal optic nerve enhancement on MRI at diagnosis

PEDIATRIC BLOOD & CANCER, Issue 4 2008
Saro H. Armenian DO
Abstract Background In North America, retinoblastoma rarely presents with gross clinical evidence of tumor involving the optic nerve. Extent of microscopic tumor infiltration into the postlaminar optic nerve is a significant risk factor for metastasis, especially if there is tumor at the cut end. Due to poor outcomes in patients with metastatic disease, historical treatment for patients with clinical evidence of extraocular optic nerve involvement has included upfront enucleation followed by aggressive adjuvant chemotherapy. Additional orbital irradiation is advocated for individuals with optic nerve involvement at the surgical margin. Little is known about the role of neoadjuvant therapy in the setting of orbital optic nerve enhancement on magnetic resonance imaging (MRI) at diagnosis. Methods A retrospective review of consecutive retinoblastoma cases at Childrens Hospital Los Angeles over a 3-year period (2004,2006) found to have gadolinium contrast enhancement in the proximal portion of optic nerve on MRI at diagnosis. Results Nine patients fit the inclusion criteria. Two had secondary glaucoma of a sufficient degree to cause an enlarged eye (buphthalmos). Median age at presentation was 17 months (2,36 months). All patients received neoadjuvant chemotherapy prior to enucleation. Only two received external beam radiation. All are disease-free with a median follow-up of 22 months (12,41 months). Conclusions Neoadjuvant chemotherapy is well tolerated prior to enucleation of retinoblastoma-containing eyes associated with contrast enhancement of the proximal optic nerve on MRI at diagnosis. Such an approach may be used to decrease intensity or duration of chemotherapy and need for external beam radiation. Pediatr Blood Cancer 2008;51:479,484. © 2008 Wiley-Liss, Inc. [source]

Progress in monitoring inflammation in JIA

ACTA OPHTHALMOLOGICA, Issue 2009
B BODAGHI
Purpose To analyze the most appropriate strategy to monitor ocular inflammation in children with juvenile idiopathic arthritis - associated uveitis. Methods Slit lamp biomicroscopy is widely used to evaluate the importance of anterior segment flare and cells in children with anterior uveitis. However, different studies have clearly shown that other tools such as laser flare photometry and OCT may improve the monitoring during the follow-up. Therefore, both tests are performed in all children referred to our Department for the management of JIA-associated uveitis. Results Laser flare photometry showed for the first time that active ocular inflammation may be associated with a significant level of flare even in the absence of detectable cells. This is a major finding to start a therapeutic approach or change it for a more aggressive strategy and monitor the decrease of flare. Moreover, the level of flare decrease under therapy may predict further serious complications such as secondary glaucoma or cataract. OCT features are important to identify macular alterations in nearly 85% of children with anterior uveitis associated with JIA. Conclusion Both laser flare photometry and OCT are non invasive and quantitative methods that may significantly improve the visual outcome of JIA-associated uveitis. [source]

Glaucoma associated with KPros

ACTA OPHTHALMOLOGICA, Issue 2009
K HILLE
Purpose Glaucoma is one of the most serious problems in Keratoprostheses. Already glaucoma is very frequent in patients with severe changes of the ocular surface requiring keratoprosthesis surgery. About 50% of those patients have pre-existing secondary glaucoma. Preoperatively all efforts should be done to detect its presence very early on. In KPro detection of glaucoma with traditional aids is difficult. A rough estimation of the tension by digital palpation will be the only available method. All indirect clues such as the medical history of glaucoma, echographic signs of disc cupping and anterior synechiae and examination of the visual field should be considered. Methods The incidence of postoperative secondary glaucoma vary among the different kinds of prostheses according to the surgery affecting the anterior segment and the long term anatomic results. In Osteo-Odonto-Keratoprostheses (OOKP) the most vision threatening complication is a primary or secondary glaucoma, due to the extended interventions required in the anterior segment. In Boston Keratoprostheses the risk seems to be somehow less. Results As the absorption of topical anti-glaucomatous medication will not reach the inner eye because of the anatomic barrier in KPro the only promising possibilities of treatment are systemic carbonic anhydrase inhibitors, different kinds of aqueous shunts and endo-cyclo-laserphotocoagulation. Conclusion Glaucoma is still a mayor problem in KPro. PS: This lession will be presented at the KPro-Meeting!! [source]

Ocular manifestations in liver transplant recipients with familial amyloid polyneuropathy

ACTA OPHTHALMOLOGICA, Issue 5 2008
Ola Sandgren
Abstract. Purpose:, To evaluate postoperative ocular involvement in Swedish liver transplant (LT) recipients with familial amyloid polyneuropathy (FAP). Methods:, Routine ophthalmological examinations were performed in 48 LT recipients, with particular attention given to amyloid deposition in the anterior segment and the vitreous body. Medical records were scrutinized for information regarding neurological impairment at the time of the LT. The diagnosis was secured in all cases by examining for amyloid deposits in biopsy specimens and positive genetic testing for amyloidogenic transthyretin (ATTR) Val30Met mutation. Results:, Six patients (12.5%) developed vitreous opacities within the post-LT observation period. The first opacities were seen 40 months after transplantation, 8 years after the onset of systemic disease. Four patients (8%) developed secondary glaucoma, the first of which was observed 18 months after the procedure and 6.5 years after the onset of disease. Sixteen patients (33%) developed deposits on the anterior surface of the lens. Scalloped pupillary margins were noted in 10 patients (21%). Conclusion:, The prevalence of eye complications increases with time after LT and regular follow-up is necessary, especially to disclose the development of glaucoma , a complication with insidious symptoms of which patients are normally unaware.

Atrial septal defect with interatrial aneurysm and Axenfeld-Rieger syndrome

ACTA OPHTHALMOLOGICA, Issue 1 2000
Necdet A. Bekir
ABSTRACT. Purpose: The aim of this presentation is to report a rare association between interatrial aneurysm and Axenfeld-Rieger syndrome. Methods: We present a 20-year-old girl with Axenfeld-Rieger syndrome, in whom the diagnosis was confirmed by the facial dysmorphic appearance, slit-lamp examination, applanation tonometer, gonioscopy, and cardiovascular examination. Results: The patient had prominent Schwalbe's line in all quadrants, iris atrophy, and secondary glaucoma in both eyes. The echocardiogram revealed an atrial septal defect with interatrial aneurysm. Conclusion: This is the first case report of coexisting Axenfeld-Rieger syndrome and interatrial aneurysm. We would like to stress that aneurysm can be a potential occult source of cerebral embolism.
