Corneal cross-linking for treatment of corneal ulcers
This was an observational cohort study looking at the usefulness of photo activated chromophore for infectious keratitis-corneal collagen cross-linking (PACK-CXL) in reducing the time to heal in suppurative corneal ulcers. This study, conducted in a tertiary care centre in South...
Microvasculature changes of mCNV after ranibizumab treatment using OCTA
In this study the authors aim to evaluate the vascular changes of myopic choroidal neovascularisation (mCNV) after ranibizumab treatment using optical coherence tomography-angiography (OCTA). The 3×3 OCTA en face images were analysed for the absence / presence of mCNV, CNV...
Vision screening standards for fitness to drive
Most countries require that vision meets a pre-defined standard in order to be legally permitted to drive, but these standards vary widely. The primary method by which vision is assessed to determine suitability for driving is by measuring visual acuity...Portable corneal topography – exploration of a prototype
Ophthalmic imaging devices, such as corneal topographers, are not widespread in the developing world. A small device that connects to a smartphone might be a solution to improve developing nation access to corneal imaging. I recently had the opportunity to...The role of aspirin in the treatment of NAION: Benefits and controversies
Non-arteritic anterior ischaemic optic neuropathy (NAION) is the most common acute optic neuropathy in individuals over 50 with estimated prevalence of 2–10 per 100,000 people, characterised by sudden, unilateral vision loss due to ischaemic injury to the optic nerve head....
Effects of topical anaesthetic on intraocular pressure
This prospective interventional study assessed the effects of repeated intraocular pressure (IOP) using Goldmann applanation tonometry and applanation resonance tonometry in six volunteers. Previous literature supports IOP reduction using repeated applanation tonometry. Repeated IOP measures were taken alternately on 12...
Effects of blood donation on the physiology of the eye
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...
