PURPOSE: To investigate the change in the refractive status of patients who were recently diagnosed with diabetes mellitus . METHOD: The study was performed in the patients diagnosed with recent diabetes using various biochemical tests & clinical examinations. Fasting plasma glucose (FPG) levels were measured along with the refractive errors initially and after four weeks . The difference between the two was evaluated . RESULTS: The average value of the initial measurement were as follows : FPG level – 396 mg/dl , refractive value – +2.0 D The average values after four weeks were: FPG level – 202 mg/dl , refractive value – +0.50 D CONCLUSION: Refractive error is affected in patients with newly diagnosed diabetes mellitus.
