How does cataract surgery affect eyes with wet AMD?

In this retrospective cohort study the authors’ primary objective was to assess whether cataract surgery in eyes with wet age-related macular degeneration (AMD), triggered its progression. The surgical group comprised of 40 eyes versus 42 eyes in the non-surgical control...

Microperimetry of subretinal drusenoid deposits

Subretinal drusenoid deposits (SDD), originally termed ‘reticular pseudo-drusen’, have recently been identified by histology and optical coherence tomography (OCT) as aggregations located in the subretinal rather than the sub retinal pigment epithelium (RPE) space. These deposits affect the amount of...

Investigating the effect of signal strength on mean retinal nerve fibre layer

The aim of this study was to determine the effect of signal strength on mean retinal nerve fibre layer (RNFL) using spectralis optical coherence tomography (S-OCT). Thirty normal subjects were imaged with S-OCT using variably dense Bangerter foils to alter...

Objective vs. subjective torsion measures

This study aimed to explore the relationship between subjective and objective torsion in normal individuals with no manifest strabismus. The study included 118 eyes of 59 normal people aged >15 years using Heidelberg OCT and the Torsionometer. There were 27...

Characteristics of cherry red spot on optical coherence tomography

In this study the authors report optical coherence tomography (OCT) characteristics of cherry red spot from three cases of Tay-Sachs and one case of Niemann Pick diseases to determine associated factors and potential visual implications. This was a retrospective case...

MCQs for FRCOphth Part 1

The FRCOphth Part 1 is the first of the fellowship examinations set by the Royal College of Ophthalmologists. It is considered one of the hardest and challenging examinations focusing on the theoretical knowledge of the learning outcomes set in the...

OCT angiography and retinal vein occlusions

In this retrospective, observational case series, the authors set out to evaluate the morphology of the superficial and deep capillary plexa of eyes that suffered a retinal vein occlusion (RVO) on OCT angiography (OCTA) and compare the findings with fluorescein...

Four key questions and answers for glaucoma practitioners

In this discussion paper the authors pose four questions for the clinician diagnosing and monitoring glaucoma, and supply evidence-based answers. Worldwide, the most common functional test used to diagnose and monitor glaucoma is static automated perimetry, most typically with a...
