A case of retinal cavernous haemangioma – don’t let it slip through the grapevine

We present a case of a seven-year-old male who presented to the emergency eye referral clinic with red eye. He was diagnosed and treated for allergic conjunctivitis, however, on clinic review, wide field retinal imaging was performed (as has been...

Macular pigment and dark adaptation in older population with normal maculas

Macular pigment (MP) such as lutein, zeaxanthin and meso-zeaxanthin are highly concentrated in the fovea. They protect the retina from damage of ambient blue light via antioxidant properties. In older eyes with normal healthy retina, macular pigment optical density (MPOD)...

The embryology of the eye

Nobody claims to like embryology. At least nobody I know. It has been a neglected part of the curriculum since time immemorial and a vicious cycle occurs in which those with an incomplete understanding fail to appreciate the inherent beauty...

Assessment of retinal capillary VD and FAZ area in CSC using OCTA

The authors aim to report a cross-sectional, case controlled study, the purpose of which was to access the retinal capillary vessel density (VD) and foveal avascular zone (FAZ) area in acute and chronic central serous chorioretinopathy (CSC) patients compared to...

Retinal vessel diameter in pseudoexfoliation

Pseudoexfolation (PEX) is characterised by deposition of fibrillary extracellular material on ocular and extraocular tissue. Studies have shown that deposition in vascular structures cause hypoxia and ischaemia. In the eye, a decrease in blood supply to the optic nerve can...

Features of AMD treatment non-responders

This is a retrospective consecutive case series of 365 eyes with age-related macular degeneration (AMD) who had three monthly intravitreal aflibercept treatments for at least 12 months. Responders were defined as complete resolution of exudation, intraretinal oedema, subretinal fluid, pigment...

Nerve head in healthy humans using OCT-angiography

Optical coherence tomography angiography (OCT-A) is a recent, dyeless, and noninvasive imaging technique for evaluating depth-resolved vascular status by capturing the dynamic motion of the erythrocytes. It provides the flow map of major vessels and capillary plexuses separately in different...

Inflammation and microvascular changes in diabetic retinopathy

Studies have shown that neurodegeneration and inflammation in the retina start early in diabetic retinopathy (DR) and can be present before the latter is clinically evident. The aim of this retrospective review of 99 diabetic patients was to evaluate retinal...

Cutaneous malignant melanoma metastasis to pseudophakic lens

Metastases to the eye and orbit are rare and intraocular cutaneous malignant melanoma metastasis (ICMM) is exceedingly rare, representing around 5%. There have only been three previous cases of ICMM to the lens in the literature, all of which presented...

Diabetic Macular Oedema

Diabetes mellitus is a metabolic disorder that affects the metabolism of all three categories of carbohydrates, lipids and proteins. This condition is characterised by chronic hyperglycaemia [1]. This can cause end organ damage. The estimated worldwide diabetes prevalence for 2010...

Migraine attack: does retinal and peripapillary blood flow change?

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...

OCTA in angioid streaks

This paper reports on the optical coherence tomography angiography (OCTA) features of choroidal neovascularisation (CNV) secondary to angioid streaks and the ability to predict CNV activity. A total of 38 eyes of 19 patients were included in the study. Thirty...
