A Study to Evaluate the Intraocular Pressure Variations in Type 2 Diabetes Mellitus.

Aim of the study was to evaluate the intraocular pressure variations in type 2 diabetes mellitus. Objectives of the study was 1. To establish if there is an increase of intraocular pressure in type 2 diabetes mellitus. 2. To evaluate if the increase in intraocular pressure has any relation to the glycosylated hemoglobin levels. 3. To study the types of primary glaucoma and establish the most common type of glaucoma seen in the study group. The findings of this study are as follows: The mean IOP in the study group was found to be 14.54±3.69 mmHg.2.5% of patients had IOP 20mmHg In our study group, patients diagnosed to have POAG, the mean HbA1c was 6.92±1.40 %, indicating good-fair glycemic control. The patients diagnosed to have OHT, mean HbA1c was 6.67±0.31%, indicating good glycemic control. The patients diagnosed to have NTG, the mean HbA1c was 6.65±0.35 %.The present study showed prevalence of POAG of 6.0%, OHT 3.0% and NTG 2.0% Conclusion: Diabetics are more prone for developing raised IOP. POAG being the most common type in the study group which constituted 6 % there by showing a strong association between POAG and diabetes. The strength of the association between diabetes and glaucoma did not vary by the degree of glycemic control. The regular screening for glaucoma in type 2 diabetic patients is strongly recommended.
