EYE - Cataract
As the boundaries between technology and biology blur, retinal prosthetics, often dubbed ‘bionic eyes’, present a ground-breaking paradigm shift in addressing blindness. This article delves into the captivating scientific intricacies of these neural interfaces, exploring their mechanisms of action, current...
Principles of contact lens fitting in keratoconus
Keratoconus is an ectatic condition of the cornea characterised by progressive conical distortion with irregular astigmatism, myopia and apical protrusion. Most cases progress slowly resulting in varying degrees of myopic astigmatism. Management of keratoconus includes spectacles, soft contact lenses, a...Large-scale study uncovers demographic and sex factors behind genetic cause of age-related visual loss
A new study has identified a major genetic contributor to Fuchs’ Endothelial Corneal Dystrophy (FECD), a common cause of vision loss, also highlighting the significant roles of sex and ancestry. FECD is a common, inherited eye condition that primarily affects...
Maintenance therapy for CMV endotheliitis
Cytomegalovirus (CMV) has been associated with corneal endotheliitis, leading to endothelial cell loss and corneal decompensation. CMV corneal endotheliitis recurrence can affect between 5-60% of eyes after cessation of anti-CMV therapy. Each recurrence of endotheliitis has a detrimental effect on...
Same day air bubble removal after DSEK/DSAEK
A complete air removal on same day as descemet’s stripping endothelial keratoplasty (DSEK/DSAEK) leads to prompt restoration of the anterior chamber and thus has been hypothesised to assist with the recovery of endothelial function and promote graft adhesion. The results...

EYE - Glaucoma
The authors report a case of macular hole post YAG peripheral iridotomy (PI) of a patient with pre-existing vitreomacular adhesion. Although a relatively safe procedure, some anterior segment complications are well documented such as corneal endothelium damage, rise in IOP,...

EYE - Vitreo-Retinal
This review covers viral causes of anterior uveitis. A viral aetiology should be suspected when anterior uveitis is accompanied by ocular hypertension, diffuse stellate keratic precipitates or the presence of iris atrophy. Most common viruses associated are herpes simplex, varicella-zoster...

EYE - Cornea
The human retina is unique in the central nervous system (CNS) in that it can be directly visualised non-invasively. Technological advances of several imaging modalities, including optical coherence tomography (OCT), multichannel scanning laser ophthalmoscopy (SLO) and fundus photography, have afforded...

EYE - General
Introduction A sinus mucocele is an epithelium-lined sac filled with mucus and desquamated epithelium. It forms secondary to inflammatory processes that occur in a sinus with an obstructed ostium. Predisposing conditions include previous trauma, surgery, tumours, anatomical abnormalities, and chronic...
