Among working-age adults, it is among the most prevalent consequences of diabetes and a main cause of blindness. Higher blood sugar levels weaken and damage retinal blood vessels, which leak fluid or bleed and result in vision issues.
Early on, diabetic retinopathy sometimes exhibits no symptoms at all. Patients may have black patches, hazy vision, changing vision, poor colour perception, and eventually visual loss as the condition worsens. Risk factors include smoking, poor blood sugar control, high blood pressure, diabetes duration, and high cholesterol.
Maintaining appropriate blood pressure, sugar, and cholesterol levels helps prevent diabetic retinopathy. Early identification and intervention depend critically on regular thorough eye exams. Advanced stages of treatment call for vitrectomy to remove blood from the inside of the eye, anti-VEGF injections to lower swelling, and laser surgery to plug leaking blood vessels. Early diagnosis and suitable treatment help people with diabetes to avoid significant vision loss and safeguard eye health.
