Role of macular hole angle in macular hole closure.

Aim: To evaluate correlation of various spectral-domain optical coherence tomography (SD-OCT) parameters including macular hole angle as well as various indices with anatomical and visual outcomes after idiopathic macular hole repair surgery.

Methods: Retrospective study of 137 eyes of 137 patients who underwent idiopathic macular hole repair surgery between January 2008 and January 2014 was performed. Various qualitative parameters such as presence of vitreomacular traction, epiretinal membrane and cystic edges at the macular hole as well as quantitative parameters such as maximum diameter on the apex of the hole, minimum diameter between edges, nasal and temporal vertical height, longest base diameter and macular hole angle between the retinal edge and the retinal pigment epithelium were noted.

Retinal ganglion cells thinning in eyes with nonproliferative idiopathic macular telangiectasia type 2A.

Purpose: To analyze the changes in retinal ganglion cells (RGCs) in eyes with nonproliferative macular telangiectasia type 2A (MacTel), by evaluating macular ganglion cell-inner plexiform layer (GCIPL) thickness and macular retinal nerve fiber layer (RNFL) thickness in comparison to age-matched healthy volunteers.

Methods: We performed a retrospective analysis of 99 eyes (53 subjects) with nonproliferative MacTel who underwent fundus fluorescein angiography and spectral domain optical coherence tomography using Cirrus HD-OCT. We also included 44 eyes of 33 age-matched healthy Indian volunteers as control group.

Multifocal electroretinography in type 2 idiopathic macular telangiectasia.

Background: To characterize the electroretinographic response of the macula by multifocal electroretinography (mfERG) in patients with type 2 idiopathic macular telangiectasia (MacTel).

Methods: A prospective study of mfERG in patients with type 2 MacTel was conducted from April 2009 to November 2009. mfERGs were recorded using a visual evoked response imaging system (MonElec2, Metrovision, Perenchies, France).

Bilateral simultaneous acute angle closure caused by sulphonamide derivatives: a case series.

The sulphonamide group of drugs is implicated in bilateral acute angle closure (AAC) due to an idiosyncratic response. We report a series of three cases with bilateral AAC caused by different sulphonamide derivatives, their presentation and management.

Prevalence and risk factors for primary glaucomas in adult urban and rural populations in the Andhra Pradesh Eye Disease Study.

Purpose: To compare the prevalence of and risk factors for primary open-angle glaucoma (POAG) and primary angle-closure glaucoma (PACG) in urban and rural populations in the Andhra Pradesh Eye Disease Study.

Design: A population-based, cross-sectional study using a stratified, random, cluster, and systematic sampling strategy.

Participants: Between 1996 and 2000, participants from 94 clusters in 1 urban and 3 rural areas representative of the population were included.

Clinical measurement and categorization of optic disc in glaucoma patients.

Background: Assessment of optic disc size is an important component of optic nerve head examination. Agreement between different methods of disc size measurements is not very good.

Purpose: To assess the agreement between the disc size assessed by Heidelberg retina tomograph (HRT) and stereobiomicroscopy with a 90 diopter (D) lens.
