Importing iron to the retina

In the retina, iron is particularly critical for the visual phototransduction cascade. In the retinal pigment epithelium (RPE), RPE65 activity leads to 11-cis-retinaldehyde, the photosensitive component of rhodopsin production and iron containing enzymes are necessary for disc replacement in photoreceptor...

Role of fundus autofluorescence patterns and baseline atrophy area on geographic atrophy progression

Central geographic atrophy (GA) is one of the morphological sub types of late-stage macular degeneration. The natural course of the disease is characterised by expanding areas of macular atrophy, which cause absolute scotoma. Fundus autofluorescence (FAF) is derived from lipofuscin...

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...

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)...

Moorfields Education: Ophthalmic peri-operative care pathway

The course will cover the patient pathway from the time they are listed in clinic for surgery through to Pre-assessment and on to the day of surgery until discharge.

My work experience with Great Ormond Street Hospital Young Persons’ Advisory Group for Research

For my school work experience I had the amazing opportunity to attend and work with the Great Ormond Street Hospital (GOSH) Young Persons’ Advisory Group for research (YPAG) (Figure 1). The GOSH YPAG is a group of young people aged...

Sickle cell eye disease: an overview of vitreoretinal complications and their surgical management

Sickle cell disease is the most common genetic disorder worldwide and is associated with lifelong anaemia, intermittent pain and multi-organ morbidity. Ocular involvement can be associated with significant visual impairment due to the complications of proliferative sickle retinopathy (PSR). Occasionally...

Expert vs. non expert grading of ROP from digital video images

The primary purpose of this study was to determine whether digital video images of the retina obtained using an indirect ophthalmoscope imaging system could be accurately graded for zone and stage of retinopathy of prematurity (ROP) and the presence of...

Insights in resistant diabetic macular oedema

This article gives a bird’s eye review of the different modalities for the treatment of diabetic macular oedema (DME). The debut of anti-VEGFs has brought a paradigm shift in DME management. This treatment has now become a major breakthrough in...

Autofluorescence patterns in subretinal haemorrhages associated with neovascular age-related macular degeneration

The aim of this retrospective study was to describe the surgical results and fundus autofluorescence (FAF) patterns occurring in sub-macular haemorrhage (SMH) of duration <60 days in age-related macular degeneration (AMD). Notes from 39 eyes of 39 patients with SMH,...

Chandelier-assisted versus standard scleral buckling for rhegmatogenous retinal detachment repair. Systematic review and meta-analysis

Despite a significant global decline in standard scleral buckling (SSB) procedures for rhegmatogenous retinal detachment (RRD), it continues to hold its place as an essential treatment option, offering distinct advantages such as cost-effectiveness, preservation of the vitreous, improved final visual...

The management of chronic central serous chorioretinopathy

Central serous chorioretinopathy (CSCR) is a common retinal disease characterised by one or more serous neurosensory detachments. Patients present with acute onset blurring of vision, metamorphopsia and / or central scotomas. The condition is six times more common in men...
