Abstract

Background: High intraocular pressure (IOP) is discussed as a risk-factor for ocular disorders such as diabetic retinopathy and optic nerve atrophy. Also, type 2 diabetes is mentioned as a risk-factor for increased intraocular pressure. There was not any study comparing the intraocular pressure in patients with type 2 diabetes and normal subjects. Regarding the increasing prevalence of diabetes, especially in our society, this study aimed to determine the relationship between the intraocular pressure and duration of diabetes mellitus.Methods: In a descriptive analytical study, the records of patients with type 2 diabetes, who were admitted to Feyz hospital, Isfahan, Iran, during 2013-2014, were studied. The Demographic characteristics, intraocular pressure and duration of diabetes were collected and analyzed.Findings: The mean ± standard deviation of duration of diabetes was 12.2 ± 5.6 years (range: 1-25) and the mean ± standard deviation of intraocular pressure in right (OD) and left (OS) eyes was 15.6 ± 3.5 and 15.5 ± 3.5 mmHg, respectively. Between the duration of diabetes and intraocular pressure, a significant correlation, with the rate of 8%, was found (P = 0.006).Conclusion: Intraocular pressure, in patients with type 2 diabetes, depends on many factors including age, sex, duration of diabetes and related disease. Also, due to lack of proper control of diabetes, different parts of the body, especially the eyes, are exposed to the destructive effects of diabetes and impaired performance. Despite all the progresses in the treatment of diabetic retinopathy, prevention is still the most appropriate way. Sugar and blood pressure control, proper nutrition and regular physical activity can reduce the risk of diabetic retinopathy.
