Surgical outcomes of phacoemulsification only and phacoemulsification combined with trabeculectomy were compared in patients with primary angle-closure glaucoma (PACG). Clinical records of 41 consecutive patients were retrospectively reviewed, and there was no difference in best-corrected visual acuity and intraocular pressure preoperatively and at the final follow-up in both study groups. Rega...

BACKGROUND Glaucoma is one of the most common causes of blindness and is usually associated with elevated intraocular pressure. In patients with primary open angle glaucoma the number of trabecular meshwork cells is decreased. Death of the trabecular meshwork cells may be a result of apoptosis. OBJECTIVE To investigate the aqueous humor levels of soluble Fas (sFas) and Fas-Ligand (sFasL) in g...

PURPOSE To assess the prevalence and mechanism of glaucoma in adults living in an urban area of southern China. METHODS Random clustering sampling was used to identify adults aged 50 years and over in Liwan District, Guangzhou. Glaucoma was diagnosed with the ISGEO (International Society of Geographical and Epidemiological Ophthalmology) classification scheme. All subjects underwent gonioscop...

During the course of negative provocative test for closed-angle glaucoma using pilocarpine and phenylephrine 60% of eyes develop significant reductions in outflow facility at some stage during the test. It is shown that these reductions can be explained by postulating the presence of partial-angle closure since: (1) A random sample (6) of 53 eyes showing an abnormal response subsequently had a ...

Glaucoma, a leading cause of blindness worldwide, is currently defi ned as a disturbance of the structural or functional integrity of the optic nerve that causes characteristic atrophic changes in the optic nerve, which may lead to specifi c visual fi eld defects over time. This disturbance usually can be arrested or diminished by adequate lowering of intraocular pressure (IOP). Glaucoma can be...

PURPOSE To determine whether or not there is an association of the methylenetetrahydrofolate reductase (MTHFR) C677T polymorphism with disease in cohorts of primary open-angle glaucoma (POAG) and primary closed-angle glaucoma (PCAG) from Pakistan. METHODS This was a prospective study consisting of 150 patients (90 POAG and 60 PCAG) and 70 control subjects. Genomic DNA was extracted from leuko...

AIM The aim was to identify the presenting symptoms and social risk factors for late presentation of primary glaucoma in newly diagnosed cases. MATERIALS AND METHODS It was a case-control study in a tertiary eye care center in Maharashtra, India. Newly diagnosed patients with primary glaucoma were classified as cases (late presenters) where there was no perception of light in one eye or sever...

AIM To determine the prevalence of glaucoma in the Meiktila district of central, rural Myanmar. METHODS A cross-sectional, population-based survey of inhabitants > or =40 years of age from villages in Meiktila district, Myanmar, was performed; 2481 eligible participants were identified and 2076 participated in the study. The ophthalmic examination included Snellen visual acuity, slit-lamp exa...

PURPOSE To quantitatively analyze central corneal thickness (CCT) in patients with primary angle closure glaucoma (PACG) and primary open-angle glaucoma (POAG), and to evaluate its correlation with severity of glaucoma. METHODS In this retrospective study, records of patients with previously diagnosed POAG or PACG at a tertiary glaucoma service were reviewed. CCT was measured by ultrasound pa...
