A comparison of light sources in retinal imaging

Before starting to talk about the light sources present in retinal imaging, it is necessary to start from the base: the light. Light is an electromagnetic wave whose smallest part is the photon (or quantum of light). A high frequency...

An interview with a glaucoma consultant: Insights for aspiring trainees

In this article, Resident Doctor Chi Kit Yan sits down with Consultant Glaucoma Specialist Salman Sadiq and explores the daily life of a glaucoma specialist, the pros and cons of the role, how trainees can prepare for this subspecialty, and...

Simulating the visual impairment symptoms of age-related macular degeneration in virtual reality

A new virtual reality application visually simulates age-related macular degeneration and demonstrates its progression over time including some Charles Bonnet syndrome hallucinations. Introduction Age-related macular degeneration (AMD) is the leading cause of blindness in developed countries with the prevalence of...

Are hospital cataract services managing more complex cases?

An audit of referral pathways and case mix in hospital cataract services. Cataract is the leading cause of irreversible blindness worldwide, causing severe visual impairment, particularly within ageing populations [1]. Gradual lens opacification impairs contrast sensitivity, visual acuity and overall...

From monofocal to premium: Understanding the expanding landscape of intraocular lenses

For many years cataract surgery was framed almost entirely as a restorative procedure. The goal was straightforward: remove the cloudy lens and replace it with a clear one, restoring distance vision and allowing the patient to function comfortably with reading...

Eyecare challenges in the Middle East: Priorities of a global ophthalmology task force

Global ophthalmology is a rapidly evolving, multidisciplinary field that integrates clinical practice, research, and policy at national and international levels. One of its main objectives is to improve eyecare equity worldwide by preventing avoidable vision impairment. Since the launch of...

The Rapid Assessment of Avoidable Blindness: How ICEH maintains the cornerstone of global eye health data

In this paper we will discuss The Rapid Assessment of Avoidable Blindness (RAAB), a survey methodology that has become the single largest source of population eye health data globally. The origins of RAAB The RAAB is a rapid, population-based survey...

My ophthalmology elective: East to West

I was fortunate to be able to complete my elective in three different parts of the world: the UK, Vietnam and Pakistan. I spent three weeks at Bristol Eye Hospital (BEH), two weeks at Cho Ray Hospital in Ho Chi...

Toric intraocular lens rotation related to the capsulorrhexis

The risk factors for postoperative rotation in the early post-operative period; a longer axial length, younger patients, and with the rule astigmatism as described by Miyake T et al. (JCRS 2014) in a case series of six eyes. This letter...

Pentacam vs. IOL Master keratometry measurement in IOL power calculations

The IOL Master measures only the anterior corneal curvature and estimates the total corneal power by assuming a fixed relationship between the anterior and posterior corneal surface. The Pentacam measures both the anterior and posterior corneal surface and therefore calculates...

Laser pointer maculopathy

The objective of this study was to describe the potential clinical presentations of retinal pathology resulting from exposure to laser pointers. The study included eight eyes of seven patients. Mean age was 18.7 years (12-36). Most were accidental self-inflicted while...

Examination of optic disc drusen using computer-based fundus analysis

This case-control study analysed the optic disc angioarchitecture in optic disc drusen (ODD) using computer-based fundus examination. A group of ODD patients were compared to a group of healthy controls with normal optic discs. The cohort included 30 healthy volunteers...
