Purpose: To report the outcome and complications of a combined surgical technique of modified deep sclerectomy and trabeculectomy (mDST) for glaucoma.

Patients And Methods: Retrospective study of 44 eyes of 43 patients with open and closed angle glaucoma who underwent mDST. Outcome measures were: Surgical Success with 3 criteria - (i) criterion 1 = intraocular pressure (IOP) ≤21 mmHg or reduced by ≥20% of pre-operative IOP or IOP ≥6 mmHg on 2 consecutive time points after 3 months; (ii) criterion 2 = IOP ≤18 mmHg or reduced by ≥30% of pre-operative IOP or IOP ≥6 mmHg on 2 consecutive time points after 3 months and (iii) criterion 3 = IOP ≤15 mmHg or reduced by ≥40% of pre-operative IOP or IOP ≥6 mmHg on 2 consecutive time points after 3 months; IOP Reduction; Use of Anti-glaucoma Medication; Complications; Visual Acuity and Postoperative Interventions.

Importance: Primary angle closure glaucoma (PACG) is a major cause of irreversible visual impairment in Asia, but there is no published data on the effect of iStent on these patients.

Background: To compare the efficacy and safety of combined phacoemulsification and iStent implantation with standard phacoemulsification in an Asian population.

Design: A prospective, single-masked, randomized study in a public tertiary eye clinic.

Purpose: To evaluate the biomechanical properties (Young's modulus) of normal (control) and glaucomatous human iris using atomic force microscopy (AFM).

Methods: Iris tissue obtained from eighteen glaucomatous subjects (equal number of eyes with primary angle closure glaucoma (PACG) and primary open angle glaucoma (POAG) and five normal subjects who underwent elective eye surgery were subjected to the estimation of Young's modulus by AFM. Force measurements were done at room temperature using Nanowizard II BioAFM.

Purpose: To evaluate the safety and efficacy of combined iStent® trabecular micro-bypass device (Glaukos, Laguna Hills, CA) and phacoemulsification in eyes with primary angle closure disease.

Methods: A two-center prospective interventional case series of consecutive patients with primary angle closure (PAC) or primary angle closure glaucoma (PACG) on at least one glaucoma medication, who underwent iStent implantation with cataract surgery. Postoperatively, patients were assessed on days 1 and 7, and months 1, 3, 6, and 12.

Congenital anomalies, such as absence, hypoplasia, bifurcation, or reduplication of various extraocular muscles, including lateral rectus muscles have been reported previously. We report a 5-year-old girl who had posteriorly malinserted lateral rectus at 15 mm from the limbus in the right eye with multiple associated ocular and systemic congenital malformations.

In this era of early treatment for retinopathy of prematurity, sick infants who develop aggressive diseases or remain oxygen and temperature dependent may be treated while they are inside the incubator itself, thus avoiding unnecessary delays. This article describes the treatment of eight infants with retinopathy of prematurity who were dependent on an incubator by using a laser indirect ophthalmoscope delivery system through the slanting transparent wall of the incubator. In this series, which is the largest to date, the relative advantages and disadvantages of the procedure are discussed.

Background: Retinopathy of prematurity (ROP) is an important cause of childhood blindness in developing countries.

Aim: To report the spectrum of ROP and associated risk factors in babies weighing > 1250 g at birth in a developing country.

Setting And Design: Institutional, retrospective, non-randomized, observational clinical case series.
