Retinopathy is one of the several eye diseases caused by sub-optimal control of diabetes and other co-existing vascular risk factors. There are a variety of less common, but in some instances more severe, eye disease that can result from diabetes. It is worth knowing that well controlled diabetes rarely ever causes eye disease no matter how long a patient has had it for. Problems with focussing, pre-mature cataracts together with accelerated progression, optic nerve disease, major retinal vascular disease and eye movement disorders are some other problems caused by poor diabetic control. Early detection of retinopathy thanks to the national screening programme, vastly improved diagnostic technology and the use of targeted intra-ocular therapy have bolstered the time-tested efficacy of Argon laser photocoagulation treatment.
