Abstract

AbstractBackground: Diabetic retinopathy occurs in the retina due to changes in blood vessels. It may cause fluid or blood leakage and fragile vascular bundles which make the sent image to the brain blurry. About half of patients with diabetes mellitus have some degrees of diabetic retinopathty. Most of the patients with diabetic retinopathy initially have mild problems in visual sense; but this situation could get worse and threaten the patients' visual power. This study aimed to compare axial length of eyes in patients suffering from proliferative and non-proliferative diabetic retinopathy.Methods: In this case-control study, from patients with type II diabetes admitted to Feyz Hospital in Isfahan, 130 patients with more than 15 years duration of diabetes, were selected. Fluorescein angiography initially was done to identify the type of retinopathy in the patients. Then, 50 patients with proliferative retinopathy (PDR) and 50 patients with non-proliferative retinopathy (NPDR) were selected among them and with the aid of IOL Master, their axial length of eyes were measurements. Data were analyzed using chi square and Student t tests via SPSS software.Finding: The mean axial length of eyes in patients (both eyes) was 23.1 ± 0.89 mm with a minimum of 20.51 and a maximum of 27.19 mm. A significant difference between the axial length of eyes in patients with proliferative (22.85 ± 0.82 mm) and non-proliferative (23.36 ± 0.89 mm) diabetic retinopathy was determined (P = 0.004).Conclusion: The mean axial length of eyes in patients with proliferative and non-proliferative retinopathy is different. Some factors such as increased intraocular pressure, myopia, hypertension, hypercholesterolemia, may also affect the axial length and the effect of these factors should also be considered in reviews.
