Eye disease (retinopathy) is a possible complication of diabetes, known as diabetic retinopathy. Diabetic retinopathy generally has no early warning signs and may surface suddenly. Sometimes, the person affected will have blurred vision, which deteriorates and improves during the course of a day. Retinopathy is medical term describing the damage to the tiny blood vessels (capillaries) that nourish the retina. The retina is located at the back of the eye and it captures light and relays the information to the brain. The tiny blood vessels are adversely affected by high blood sugar associated with diabetes. Eye disorders are treated by ophthalmologists or optometrists. Ophthalmologists are physicians and surgeons who specialize in the diagnosis and treatment of eye diseases. Opticians are technicians who can fit eyeglasses and contact lenses using prescriptions provided by an ophthalmologist or optometrist. Opticians do not diagnose or treat eye diseases. Present book has been complete to cater to the requirements of the teachers, researchers and students.
