Which condition is the leading cause of preventable blindness?

Diabetic retinopathy is indeed recognized as the leading cause of preventable blindness, particularly in working-age adults. This condition arises as a complication of diabetes, where high blood sugar levels can damage the blood vessels in the retina. Over time, this can lead to vision impairment and potentially blindness if not managed properly. Regular eye examinations can help identify the disease early, allowing for interventions that can significantly reduce the risk of vision loss.

Management strategies include maintaining tight control of blood glucose and blood pressure levels, alongside the use of laser treatments and intravitreal injections to address any significant changes in the retina. This preventative aspect is crucial since early detection and treatment can effectively prevent the progression of the disease, distinguishing it from conditions like cataracts or glaucoma, which, while serious, may not be as directly influenced by routine preventative care in the same way.
