Purpose This study evaluates the impact of phacoemulsification on trabeculectomy bleb morphology and intraocular pressure (IOP) control in patients with primary angle closure glaucoma (PACG). The study also evaluates possible alterations in these effects by intra-operative blocking of internal sclerostomy by high-density viscoelastic (visco-cushion). Methods This is a single-center, interventional, prospective study including patients with PACG who underwent phacoemulsification post-trabeculectomy.

Purpose: To evaluate the effect of phacoemulsification on intraocular pressure (IOP) and anterior chamber angle (ACA) morphology in primary angle-closure glaucoma (PACG).

Setting And Design: A hospital-based, prospective pre- and post-interventional study was carried out in 40 PAC and PACG eyes post patent PI with visually significant cataracts.

Methods: All patients underwent phacoemulsification and were evaluated for IOP control, ACA widening, and disease progression for a minimum of 6 months.

Purpose: To report the case of an extremely large overhanging bleb, extending from superior fornix to limbus, in a 57-year-old poorly controlled diabetic, six years after trabeculectomy for an uncontrolled primary open angle glaucoma (POAG) with recurrence, months after complete excision.

Methods: An overhanging bleb is defined as a filtering cicatrix which has been massaged downward over the cornea by eyelid action. It has been linked to anti-metabolite use during glaucoma filtering surgery.

Purpose: To evaluate the impact of color vision deficiency (CVD) in medical undergraduates by a more clinically applicable test.

Methods: Cross-sectional study of 31 students with CVD (Ishihara diagnosed) asked to identify subject-specific signs/tests requiring color identification on a customized medical multispecialty designed color album test (CAT). They were further subjected to Farnsworth D-15 testing.

Article Synopsis
  • The study focused on COVID-19-associated rhino-orbital-cerebral mucormycosis (ROCM) in India, examining patient demographics, risk factors, symptoms, and management outcomes during the pandemic's second wave.
  • Key findings revealed that 78% of patients had diabetes and a majority required oxygen support; most cases showed ROCM symptoms within 10-15 days post-COVID diagnosis.
  • Final outcomes indicated a 14% mortality rate, significantly reduced through surgical interventions, highlighting the role of corticosteroids and diabetes as major contributors to ROCM development.

Purpose: To compare results of a novel "conjunctival frill/smile incision" on surgically induced astigmatism (SIA) and patient discomfort vs conventional trabeculectomy in the initial postoperative period.

Methods: Sixty trabeculectomy cases were subjected to either conjunctival frill incision, performed 1.5-2.

Primary angle closure glaucoma is a major cause of visual morbidity in Asia, which hosts 80% of the worldwide cases. In India, primary angle closure glaucoma (PACG) comprises almost 50% of adult glaucomas in hospital setting with its asymptomatic presentation predominating at 80%. Early diagnosis is critical to prevent the blinding trajectory of this disease, which is purported to cause twice as much blindness compared to open angle glaucoma.

Purpose: Literature is relatively silent on safety profile and predictability of orthokeratology lenses in terms of myopia correction and prevention of further progression, especially in semi-tropical countries; this study was designed to fill this gap.

Methods: This prospective, intervention case series enrolled 30 eyes of 30 patients with myopia up to -5.5 diopters (D).

We report the case of congenital ectropion uveae in a 10-year-old boy with intractable unilateral glaucoma but no systemic association. Glaucoma in congenital ectropion uveae is often poorly responsive to medial therapy and requires surgical intervention. Satisfactory results are possible if diagnosis is established early and timely surgery performed, as was the case in our patient.

Aim: To report a case of bilateral phacomatosis pigmentovascularis (PPV), in a young male,presenting with developmental glaucoma and high myopia along with systemic features of klippel trenanauy weber (KTW) syndrome.

Background: The co-existence of oculodermal melanocytosis (ODM)and port-wine stain was termed PPV by Ota. Port-wine stain presents as part of Sturge-Weber syndrome (SWS).

Purpose: To report long-term safety and efficacy of trabeculectomy with collagen implant in Indian population.

Methods: All cases of trabeculectomy with Ologen Collagen Matrix implant performed over a 7-year period from May 2008 through April 2015 at a tertiary referral institute were reviewed. A total of 30 eyes of 28 patients were included in the study with two patients undergoing bilateral trabeculectomy.

Introduction: Ocular decompression retinopathy (ODR) is a relatively rare entity with variable prognosis depending on extent and pre-existing condition. This article describes profile of two cases with a brief review of the condition.

Case Report: Case 1 highlights extensive choroidal detachment with subhyaloid haemorrhage and multiple intra-retinal hemorrhages in the posterior pole seen on first post-operative day in a 6 year old child with congenital glaucoma who underwent Trab & Trab.

Purpose: To assess the role of an "empathy sensitizing module" (ESM) in ophthalmology postgraduates in promoting effective empathetic communication.

Methodology: Thirty-nine ophthalmology postgraduates were taught effective empathetic communication using specially designed module, comprising of five illustrative role-plays. We evaluated the impact of the training by (a) self-assessment of empathy quotient by residents using Jefferson Scale of Empathy (JSE scale) before and 6 weeks after ESM training and (b) nonparticipant observation (NPO) by trained faculty in real-life settings over the next 4 months.

Background: Most studies have either excluded patients using contact lens or not taken their effect while analyzing post-collagen cross-linkage (CXL) changes. This study aims to study impact of CXL on lens fit in both quantitative and qualitative manner.

Objective: To evaluate changes in CL fit post-CXL and to correlate these changes with alterations in corneal topographic parameters.

High intraocular pressure (IOP) not responding to systemic and topical anti-glaucoma medications renders the eye at risk for both intra- and post-operative complications of glaucoma filtration surgery. Laser cyclophotocoagulation is able to lower IOP in such refractory glaucoma eyes and may make the surgical event safer. This study assessed diode laser cyclophotocoagulation (DLCP) when used as a temporary measure for lowering IOP prior to performing trabeculectomy.
