PUNE: In a seminal research, a team of eye surgeons at the Pune-based National Institute of Ophthalmology have found that measuring the dimensions of the abnormal network of tiny retinal blood vessels (capillaries) can be a more reliable way of tracking the vision loss in patients diagnosed with macular telangiectasia (MacTel), than their conventional grading.
Telangiectasia is a network of blood capillaries — a type of spider veins — that some people with underlying medical conditions may get caught up with. It develops when there are problems with the tiny blood vessels around the fovea, which is the centre of the macula that gives us our sharpest central vision.
