Among diabetic macular oedema (DME) patients, those with diffuse retinal thickening (DRT) experience greater reductions in retinal thickening after undergoing focal laser photocoagulation when compared with either cystoid macular oedema (CME) or vitreomacular interface abnormalities (VMIA) patients, according to a study published online ahead of print by the British Journal of Ophthalmology.
Although there appears to be a relationship between open-angle glaucoma (OAG) and cardiovascular disease, its nature remains unknown, reported a study published online ahead of print by Eye.
Patients in need of visual corrections whose vision is not affected by existing high-order aberrations (HOAs) may have an alternative to wavefront treatment using an aberration-free method.
Quantitative analysis of colour vision defects provides the possibility of follow-up and may be a useful means for detecting early glaucomatous changes in patients with normal visual fields.
Biologists at the Florida State University, USA, have discovered a gene mutation in Zebrafish that determines if the cells develop as rods or as cones.
Many patients undergoing phacoemulsification want more than simply cataract extraction. Dr Detlev Breyer says that advances in surgical technique and IOL design have made it possible to satisfy most patients' requirements.
It is essential that clinicians familiarize themselves with the full spectrum of glaucoma medication available, concludes a study published in the March 2009 issue of Current Opinion in Ophthalmology.
