Abstract
Background and Objectives: Diabetic retinopathy is one of the four important reasons of blindness through out the world. The goal of present project was evaluation of types of diabetic retinopathy patients that were under coverage of Hamadan diabetic center in 1999.
Materials and Methods: This work was a descriptive-analytic retrospective study based on medical files of two thousands diabetic patients. It is acquired from patients’ files including ophthalmologic examination and patients past medical history and interview.
Results: Our results showed that 262 persons (96male and 166 female) of diabetic patients (13.1%). had one of the different kinds of diabetic retinopathies. The highest rate of frequency (26.6%) belonged to patients who had 16-20 years of positive history of illness. The rate of retinopathy was increased by increasing the diabetes period (p<0.01). According to our results, patients over 60 years had the highest rate (19.8%) and patients under 20 years had the lowest rate (3.1%) of diabetic retinopathy. This difference was significant (p<0.01). By evaluating factors related to diabetic retinopathy: hypertension had the highest association (54/6%). Hyperlipidemia, renal failure, cigarette smoking and ischemic heart disease were in the subsequent steps.
Conclusion: Frequency of diabetic retinopathy in our study (13.1%) was lower than other studies and hypertension was the most important risk factor.
