EYE - Vitreo-Retinal
The aim of this study was to further define and model the influence of cataract on spectral domain optical coherence tomography (SDOCT) image quality and retinal nerve fibre layer (RNFL) thickness measurements. OCT quality is influenced by opacities in the...
Effects of blood donation on the physiology of the eye

EYE - Vitreo-Retinal
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...

Idiopathic intracranial hypertension, predictors, visual outcome
In this prospective study, visual outcome of 40 patients with idiopathic intracranial hypertension (IIH) was compared with clinical and neuro-ophthalmic parameters. The purpose of this was to determine any correlation to try and predict visual outcome for IIH patients. Parameters...

Marfan syndrome, axial length, corneal curvature, ectopia lentis, visual acuity
This repeated cross-sectional study collected data in 2003-2004 and 2014-2015 to investigate changes in ocular features in Marfan syndrome (MFS) fulfilling the Ghent-2 criteria. Ghent-2 is a set of criteria by which MFS are identified and includes aortic root aneurysm...

Glaucoma, OCTA, field of vision, intraocular pressure, macula, optic nerve
Elevated IOP is important but not the sole factor responsible for retinal ganglion cell (RGC) death and optic nerve damage in glaucoma. There is increasing evidence that visual loss correlates with macular inner retinal thinning. A total of 148 eyes...
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...Migraine attack: does retinal and peripapillary blood flow change?

EYE - Neuro-ophthalmology
This prospective clinical study compared retinal and peripapillary blood flow parameters in migraine patients during an attack with healthy controls using optical coherence tomography angiography (OCTA). OCTAs were performed on 52 eyes from 26 migraine sufferers and 48 eyes from...
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 –...Changes in drusen and retinal layer volumes prior to CNV development

Age-related macular degeneration, Choroidal neovascularisation type, Drusen load, Imaging biomarkers, Retinal layer volumes
This retrospective longitudinal study looked at patients with wet age-related macular degeneration (AMD) in one eye who subsequently developed wet AMD in the fellow eye. The aim was to discover whether drusen characteristics or volumes of retinal layers correlate with...

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...

Cystoid macular edema, rhegmatogenous retinal detachment, vitreoretinal surgery
There are limited studies examining the incidence and risk factors for postoperative cystoid macular oedema (CMO) following rhegmatogenous retinal detachment (RRD) repair. Postoperative CMO is thought to be due to pro-inflammatory state, where numerous cytokines lead to tight junction dysfunction,...
