The term Diabetes is a disease in which the body cannot produce sufficient insulin to adequately control the level of glucose in their blood [1]. IOP is a routine examination in all the subjects. The measurement of IOP is usually done in both diabetics and glaucoma [2]. The commonly accepted range for normal in the general population is 10 to 21 mm of Hg [2].

It has been traditional to classify Diabetes as being type I or type II. Type I is also called insulin dependent, where the body’s immune system destroys the insulin producing beta cells in pancreas. Type II is characterized by insulin resistance and relative insulin deficiency. Any changes in retina due to diabetes are called Diabetic Retinopathy. Diabetic Retinopathy is again divided as Non-Proliferative and Proliferative type [3].
