简要总结
To determine the stage of Diabetic Retinopathy (DR) and the presenting symptoms at the time of ophthalmological examination of diabetic individuals .
详细描述
Diabetic retinopathy (DR) is the main cause of decreased vision and blindness in patients with diabetes throughout the world . In Egypt, the estimated prevalence of diabetes mellitus (DM) is expected to rise from 5-10% in the 1990s to>13% of the population over 20 years old by 2025 .
The estimation of the prevalence of diabetic retinopathy (DR) is challenging due to the great variation in the study populations, methodologies, and grading schemes .
Globally, the prevalence of DR and diabetic macular edema (DMO) is expected to rise from the estimates for the period 2015-2019 (27%) due to the expected increase in the life expectancy of people living with DM .
Diabetic retinopathy is now the 5th leading cause of blindness worldwide and is the main cause of blindness in working population .
Blindness due to diabetic retinopathy is more common in type 1 diabetics (4%) than in type 2 (1.6%) .
