Diabetes Care Urges Regular Eye Exams to Catch Silent Vision Threats
Managing diabetes involves monitoring blood sugar, medication, diet and exercise, but eye health is often neglected. On World Diabetes Day, 14 November, doctors emphasize that people with diabetes should have regular eye examinations because eye problems can develop without early visual symptoms. In India, the International Diabetes Federation reports that over 101 million adults aged 20‑79 have diabetes, a figure projected to rise to 156.7 million by 2050. Diabetic retinopathy, caused by high blood sugar damaging retinal vessels, can lead to bleeding, scar tissue and retinal detachment if untreated. Diabetic macular oedema, fluid buildup in the macula, impairs sharp vision and can hinder reading, face recognition and driving. Diabetes also increases the risk of early cataracts and certain glaucomas.
The All India Ophthalmological Society and the Vitreo‑Retinal Society of India recommend screening schedules: for Type 1 diabetes, a comprehensive dilated eye exam within five years of diagnosis and then annually; for Type 2 diabetes, an exam at diagnosis followed by annual checks. Those already diagnosed with retinopathy may need more frequent visits. During an exam, specialists examine the retina and may use retinal photography or optical coherence tomography for detailed assessment.
Patients should not wait for blurred vision or discomfort before seeing an eye specialist. While not all diabetic eye disease is preventable, controlling blood sugar, blood pressure, cholesterol, taking prescribed medication, eating a balanced diet, staying active, and avoiding smoking can reduce risk. Warning signs such as blurred vision, dark spots, floaters, difficulty focusing, distorted images, sudden flashes, a sudden increase in floaters or a dark shadow in the visual field warrant urgent care.
Treatment depends on severity. Early‑stage retinopathy may require monitoring and tighter metabolic control. Advanced cases may involve anti‑VEGF injections to halt abnormal vessel growth, laser therapy for certain retinal complications, or vitrectomy surgery for severe bleeding or retinal detachment. Early detection improves the chances of preventing serious vision loss.
