Gender variations in retinopathy

The Tromso Eye Study is a substudy of the Tromso Study; a population based longitudinal study based in Norway. The extensive 5869 participants had no diabetes and were aged between 30-87 years. Retinal images from both eyes were taken using...

Effects of blood donation on the physiology of the eye

Hypovolaemia is a state of decreased blood volume, the reduction of which reduces tissue perfusion which may in turn lead to cellular hypoxia and end-organ damage. In blood donation, 500ml of blood is collected in ten minutes. This equates to...

Colour Doppler imaging before and after orbital decompression in thyroid eye disease

In this prospective, uncontrolled study euthyroid patients with moderate to severe inactive thyroid eye disease underwent colour Doppler imaging before and after orbital decompression. Patients with dysthyroid optic neuropathy, corneal breakdown, systemic disease (diabetes, cerebrovascular accident, cardiovascular and peripheral vascular...

Microperimetry measurements in anisometropic amblyopia

The authors aimed to evaluate retinal sensitivity and fixation characteristics in children with anisometropic amblyopia by macular analyser integrity assessment (MAIA) microperimetry and to compare the results between amblyopia and fellow eyes. The study included 39 children; 21 female –...

What is paracentral acute middle maculopathy?

This is a review article characterising a clinical entity called paracentral acute middle maculopathy (PAMM). The article highlights the fact that retinal capillary plexuses are organised predominantly into three trilaminar capillary layers occupying the area between the nerve fibre layer...

Macular characteristics in unilateral idiopathic FTMH and fellow eyes

This retrospective observational study, conducted at a single site, aimed to compare characteristics of the macular structure and foveal pit in unilateral full-thickness macular hole (FTMH) and healthy fellow eyes. Full-thickness macular holes were further classified into three categories: (1)...

Endo-illumination-aided SB combined with IVT hyaluronate for RRD

The authors report a retrospective non-randomised control trial that evaluated the efficacy and safety of 25-gauge illumination-aided scleral buckling (SB) combined with hyaluronate injection for the treatment of rhegmatogenous retinal detachment (RRD). Forty-five cases were included in this study. Twenty-five...

Simulated ocular surgery: pars plana vitrectomy and scleral buckling surgery

See also Simulated ocular surgery and Simulated ocular surgery - strabismus surgery In this second article on ocular surgery simulation, we will discuss how vitreoretinal surgery can be simulated using high tech virtual reality modalities such as the Eyesi, as...

Comparison of structural and functional features in primary angle closure and open-angle glaucoma

In this large cross-sectional study, differences in structural and functional damage were assessed among patients with primary open-angle glaucoma (POAG) and primary angle closure glaucoma (PACG) with optical coherence tomography and reliable visual field testing. Two-hundred and eighty-three patients with...

AI predicts eye damage from autoimmune drug, years before symptoms appear

A novel AI tool could transform screening for patients taking hydroxychloroquine by spotting early signs of eye damage, according to a study published in Opthalmology Retina. Researchers have devised an artificial intelligence (AI) system that can detect and predict serious...

PRPF31-related retinitis pigmentosa and asymptomatic carriers

The authors present a study of 21 patients with variants in the PRPF31 gene classified as pathogenic or likely pathogenic. These variants are caused by autosomal dominant retinitis pigmentosa (RP-11). Between January 2020 and November 2021 patients underwent tests of...

Diary from my elective: a Parisian experience

The author explains how a research institute’s dedication to multidisciplinary collaboration helped him to discover a passion for academic ophthalmology. The elective aspect to the final year of a medical degree, through its change of scenery and immersion into another...
