NAGPUR: Diabetes over a period of time can severely affect vision of a person through an ailment called 'diabetic retinopathy'. Normally ophthalmologists burn retina's leaking blood vessels that cause this disease using lasers. Patients who do not respond to the laser treatment are then injected a drug called 'avastin'. A city eye surgeon Dr Ajay Ambade has now successfully tested a newer two-drug therapy to treat these patients as a part of a scientific study. Normal vision could be restored in about 23% of the patients.
The study recently presented at the Joint Congress of American Academy of Ophthalmology and European Society of Ophthalmology at Geneva received good response from the experts in the field. After about five years of onset of diabetes, most persons suffer vision impairment when fine blood vessels supplying to retina leak due to increase in blood pressure in them. The accumulated blood clots start affecting the vision. In medical terms, condition is called 'residual macular edema'. If untreated, patients can go completely blind.
