Managing a patient with open-angle glaucoma: a case study

چکیده
Mr AA is a 48-year-old shop attendant who presented at the eye unit of a teaching hospital with a history of gradual, painless vision loss. His presenting (unaided) visual acuity was counting fingers at 1 metre in the right eye and 6/60 in the left eye. Both corneas were clear, and the pupils had a slow reaction to light. There was a right relative afferent pupillary defect (RAPD). The right eye had a nuclear sclerotic cataract which precluded a good view of the optic nerve head, and a vertical cup:disc ratio (VCDR) of about 0.9, barely visible through the dilated pupil with the binocular indirect ophthalmoscope. The left eye VCDR was 0.8. Intraocular pressure (IOP) was 32 mmHg (right eye) and 30 mmHg (left eye) by applanation tonometry. Gonioscopy showed open angles in both eyes. Visual field tests (standard automated perimetry [SAP]) could not be carried out.

Aqueous Levels of Anti-Helicobacter Pylori IgG Antibody in Patients with Primary Open Angle and Pseudoexfoliation Glaucoma
Background: Glaucoma is a progressive optic neuropathy and is one of the leading causes of blindness worldwide. Different factors have been contributed in the pathogenesis of glaucoma including H. pylori infection. Objective: To determine the levels of anti-H. pylori IgG antibody in the aqueous humor of patients with pseudoexfoliation and primary open angle glaucoma, in comparison with age and ...
متن کاملAqueous Humor Levels of Soluble Fas and Fas-ligand in Patients with Primary Open Angle and Pseudoex-foliation Glaucoma
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 glau-coma 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 ...

AbstractGlaucoma management in pregnant patients is a real challenge, especially when the glaucoma is not controlled with medications. We report the results of 6 incisional glaucoma surgeries for the management of medically uncontrolled glaucoma patients during pregnancy. This retrospective, case series was conducted on the 6 eyes of 3pregnant patients with uncontrolled glaucoma using maximum t...
متن کاملPeripapillary Intrachoroidal Cavitation and Optic Pit in a Case of High Myopia and Glaucoma
Purpose: To report a case of peripapillary intrachoroidal cavitation (choroidal schisis) and optic pit in a case of high myopia and open-angle glaucoma. Case report: A 30-year-old high myopic man was referred to our clinic for presumed peripapillary choroidal tumors. In funduscopy, there were two yellow-orange and slightly elevated peripapillary lesions in both eyes with indistinct margins. A s...
متن کاملGlutathione s-transferase M1 and T1 genetic polymorphisms in Iranian patients with glaucoma
Objective(s):Glaucoma is the second leading cause of blindness and it is related to oxidative stress based on numerous studies. Glutathione S-transferases (GSTs) are members of multigenic family, which have important role in cells as an antioxidant. In the present study, we examined the polymorphism of GSTT1 and GSTM1 deletion genotypes (T0M1, T1M0, and T0M0) in 100 Glaucoma patients (41with pr...
متن کاملScreening of CYP1B1 Arg368His as predominant mutation in North Indian primary open angle glaucoma and juvenile onset glaucoma patients
In India, mutations in Cytochrome P450 (CYP1B1) are a predominant cause of not only primary congenital glaucoma (PCG) but also involved in primary open angle glaucoma (POAG) and juvenile onset glaucoma (JOAG). After ethical clearance, 100 POAG patients, 30 primary angle closure glaucoma (PACG) patients and 130 ethnically matched controls were recruited in this study. Genomic DNA was is...
