Traumatic ‘toy’ gun injury leading to permanent vision loss
Pseudoxanthoma elasticum (PXE) is a progressive, inherited disorder of connective tissue that affects the skin, cardiovascular system and retina. Ocular manifestations of the disease are related to Bruch’s membrane, a thin elastic tissue layer located between the retinal pigment epithelium...
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)...
Two-year results of a T&E aflibercept regime in caucasian PNV
This a retrospective study examining two-year outcomes of patients with pachychoroid neovasculopathy (PNV) treated with a treat and extend (T&E) regimen of intravitreal aflibercept. The mean age was 63.84 ± 7.92 years with nine males (35%) and 17 females (65%)....
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...
Retinitis pigmentosa (RP) associated cystoid macular oedema (CMO)
This is a review article from two units in the UK and Australia, highlighting the supporting evidence of possible pathogenesis and treatment modalities of CMO in RP. The authors proposed that the likely mechanisms for RP-CMO involved the breakdown of...
Ocular damage from laser pointers
This retrospective study of case notes from a tertiary eye centre over a five-year period, recruited nine children (12 eyes: eight boys) aged 9-15 years. Three presented with deteriorating vision whilst others had retinal changes noted as incidental findings at...
DALK as an early therapeutic option for Acanthamoeba keratitis
Eleven patients with Acanthamoeba keratitis (AK) were treated by early therapeutic deep anterior lamellar keratoplasty (DALK). All surgeries were performed in patients who had no response to standard medical therapy of chlorhexidine gluconate, propamidine isethionate and neomycin sulphate, within 10-15...
Nicotine accelerates diabetes induced retinal changes
This study investigated the influence of nicotine in an experimentally induced diabetic rat model. They used non-invasive high-resolution spectral domain optical coherence tomography (SD-OCT) imaging to provide quantitative information on the temporal alterations of retinal structures at the micrometer resolution...
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...
