ABSTRACT

Purpose: The current study was performed in order to determine the prevalence, age, gender and diabetic retinopathy characteristics by clinical and fluorescein angiographic examination in diabetic subjects at the ophthalmology service of the Hospital General de Mexico from 1977 to 2004.
Material and methods: All the subjects having a previous diagnosis of type 1 or 2 diabetes mellitus were included and analyzed by a complete ocular clinical history, retinal fundus examination and fluorescein angiography. Retinal fundus and angiographic images were examined and classified according to non-proliferative and proliferative diabetic retinopathy with or without macular edema.
Results: 12709 subjects with diabetes mellitus type 1 or 2 were studied and 9078 were included in this report. In 3994 (43.9%) studies no retinal signs of diabetic retinopathy were found. 5084 (56.1%) studies had retinal signs of diabetic retinopathy. 1882 (37%) were classified to have the non-proliferative variety and 3203 the proliferative form. Macular edema was present in 814 (16%) studies. The fifth and sixth decades of life were the most affected groups according to age distribution and females demonstrated to have a higher number of affected individuals than men. Diabetic retinopathy prevalence was found to be higher in type 1 diabetes mellitus than in type 2.
Conclusions: The prevalence of diabetic retinopathy is high in the diabetic population at the ophthalmology service of the Hospital General de Mexico. The priority need of educational programs directed to the diabetic and general population is emphasized, in order to understand the importance of ophthalmologic intervention in the early stages, detection and treatment of this ocular problem and the implementation of future epidemiological works.
