G laucoma is a progressive optic neuropathy with features similar to nonarteritic anterior ischemic optic neuropathy (NAION), the most common optic neuropathy causing acute vision loss. Glaucoma has an annual incidence rate of 240 per capita, while NAION has an annual incidence of 2.3 per capita among individuals older than 50 years. Early diabetes mellitus (DM)—defined as an absence of clinica...

OBJECTIVE To search for the genetic cause of juvenile-onset open-angle glaucoma (JOAG) in a Chinese family. METHODS In a 3-generation glaucoma family affected with JOAG or ocular hypertension, we screened myocilin (MYOC) and optineurin (OPTN) for mutations and investigated apolipoprotein E (APOE) polymorphisms in 6 family members, 2 of them patients with JOAG, 2 patients with ocular hypertens...

Mutations in the MYOC gene may lead to juvenile open-angle glaucoma with high intraocular pressure, and are detected in about 4% of people with adult onset glaucoma. Most of these mutations are found in the third exon of the gene encoding the olfactomedin-like domain located at the C terminus of the protein. Another olfactomedin-related protein, known as noelin or pancortin, is involved in the ...

PURPOSE To determine the distribution of WDR36 sequence variants in a cohort of patients with primary open-angle glaucoma (POAG) in the United States. METHODS All of the 23 coding exons and flanking introns of the WDR36 gene were sequenced in 118 probands from families with at least two members affected by POAG, 6 probands from juvenile-onset POAG families, and 108 control individuals. RESU...

purpose: to compare the prevalence of glaucoma among peptic ulcer patients with or without helicobacter pylori infection. methods: among 352 patients with an indication of gasterointestinal endoscopy for peptic problems, 120 patients in 18-88 years of age were included for evaluation of glaucoma. according to the results of histopathologic and urease test, they were divided into two groups: hel...

Glaucoma is a heterogeneous eye disease and a major cause of blindness worldwide. Recently, primary open angle glaucoma (POAG)-associated mutations have been found in the trabecular meshwork inducible glucocorticoid response gene (TIGR), also known as the myocilin gene (MYOC), at the GLC1A locus on chromosome 1q21-q31. These mutations occurred in a subset of patients with juvenile- and adult-on...

PURPOSE To map the gene(s) associated with autosomal dominant (AD) high-grade myopia. METHODS A multigeneration English/Canadian family with AD severe myopia was ascertained. Myopes were healthy, with no clinical evidence of syndromic disease, anterior segment abnormalities, or glaucoma. The family contained 22 participating members (12 affected). The average age of diagnosis of myopia was 8....

PURPOSE The cytochrome p450 family 1 subfamily B (CYP1B1) gene is a well known cause of autosomal recessive primary congenital glaucoma. It has also been postulated as a modifier of disease severity in primary open angle glaucoma (POAG), particularly in juvenile onset families. However, the role of common variation in the gene in relation to POAG has not been thoroughly explored. METHODS Seve...

Experience with the removal of complicated cataract by lensectomy in patients with juvenile chronic iridocyclitis (JCI) has so far been limited. The results of lensectomy were reviewed retrospectively in 131 patients with JCI (187 eyes). The mean follow up period was 5 years 4 months. The main operative complication was accidental loss of lens material into the vitreous cavity. The postoperativ...
