AS‐OCT utility for corneal lacerations in pediatric patients

Acta Ophthalmologica, 2016
PurposeThe purpose is to evaluate the utility of optical coherence tomography anterior segment (AS‐ OCT) through different clinical cases of corneal lacerations. OCT technology will help us to determine the corneal anatomy after trauma and deciding the therapeutic approach, in addition to guiding the prognosis, and evaluating response to treatment ...

Descemet’s membrane detachment: An updated comprehensive review of etiopathogenesis, diagnosis, and management

Indian Journal of Ophthalmology
The Descemet membrane (DM) is the basement membrane of corneal endothelial cells, which are responsible for maintaining corneal transparency. DM detachment (DMD) can occur due to various reasons, with the most common etiology being post-surgical.

Utilization of Anterior Segment Optical Coherence Tomography Enhanced High Resolution Corneal In Measuring Pterygium Thickness

Sains Medika, 2018
Introduction: As various pterygium morphologies have been advocated as contributing factor on corneal astigmatism, little support in the literature available in establishing techniques in measuring pterygium thickness as clinical indicator.
