Quantifying microstructural changes in retinitis pigmentosa using spectral domain - optical coherence tomography.

Background: Most patients of established retinitis pigmentosa (RP) have subnormal peripheral vision and heavily rely on central vision for their daily activities. Central visual acuity is dependent on photoreceptor survival at the macula. Identification of structural changes that precede visual loss is essential.

Duane retraction syndrome type 1 with Usher syndrome type 2: an unreported association.

Duane retraction syndrome is characterized by globe retraction and palpebral fissure narrowing on adduction, with restriction of abduction, adduction, or both. Usher syndrome type 2 consists of congenital bilateral sensorineural hearing loss and retinitis pigmentosa. The authors present a case with a yet unreported association between Duane retraction syndrome type 1 and Usher syndrome type 2.

Prevalence of diabetes mellitus and hypertension among Indian glaucoma patients and evaluation of systemic therapy.

To study the prevalence and systemic control and evaluate the adequacy of therapy of diabetes mellitus (DM) and hypertension (HT) in glaucoma patients visiting a tertiary care eye facility at a university hospital. Consecutive cases with primary open-angle glaucoma (POAG) or primary angle-closure glaucoma (PACG) attending the outpatient services were evaluated for the presence of DM and HT and any systemic/ocular medications being taken were recorded. Of 615 glaucoma cases evaluated, 281 (45.

Drug-induced Angle-Closure Glaucoma.

Drug-induced angle-closure glaucoma is an important entity for the ophthalmologist as well as the general physician as it represents a preventable cause of potential blindness. This brief review highlights the fact that a high index of suspicion, in a susceptible individual followed by confirmation on appropriate imaging modality (UBM, ultrasound or anterior segment OCT) can alleviate the threat to sight and also help to institute appropriate therapy.
