Glaucoma burden and its profile in a tertiary care centre of North-East India: A retrospective hospital-based study.

Purpose: To estimate the proportion and pattern distribution of glaucoma disease in a teaching hospital of North-East India.

Materials And Methods: Retrospective hospital-based study of glaucoma cases from January 2014 to December 2022.

Results: Out of a total of 89725 new patients, 449 patients had glaucoma with a prevalence of 0.

Ocular biometry characteristics and corneal astigmatisms in cataract surgery candidates at a tertiary care center in North-East India.

Purpose: The purpose of this study is to determine the ocular biometry characteristics and corneal astigmatisms using partial coherence laser interferometry in patients aged 40 years or above undergoing cataract surgery in a medical college in North-East India.

Methods: In a hospital-based cross-sectional study, ocular biometry characteristics such as axial length (AL), anterior chamber depth (ACD), white-to-white (WTW) diameter, corneal power (K), and corneal astigmatisms (D) of consecutive eligible cataract patients in a medical college in North-East India between January 2015 and December 2017 were determined using the intraocular lens (IOL) master. Height and weight were also measured.

Evaluation of pattern ERG as a visual prognosticator in chiasmatic tumours.

Background: Tumours compressing the optic pathway may lead to irreversible loss of vision that can be detected by pattern electroretinogram owing to its relation to ganglion cell function. This study aims to assess whether pattern electroretinogram is a useful tool to predict visual outcome following decompressive surgery for sellar and parasellar tumours.

Design: Prospective, non-randomized study.
