A Comparative Study of Retinal Sensitivity Test between Diabetic and Normal Adult

Diabetes mellitus is one of the most common diseases in the world and its prevalence is growing in both developed and developing countries. The complications of diabetes in the eye are due to damage in small blood vessels of retina known as Diabetic Retinopathy and Macular edema. This leads to gradual vision loss and blindness.

The present cross sectional observational study comprising of 84 cases was conducted in the Department of Physiology, Pt. Jawaharlal Nehru Memorial Medical College Raipur in collaboration with the Upgraded Department of Ophthalmology, Dr. B.R.A.M. Hospital, Raipur (Chhattisgarh) from August 2014 to July 2015. In the study, individuals was comprised in two different group i.e. Type 2 diabetic patients (Case) and normal healthy (Control) of age 30 years or older. Eye examination includes Best-corrected visual acuity, refraction, intraocular pressure, Slit lamp examination & Humphrey Visual Field Automated Perimetry 30-2 test were performed.

In diabetic cases 3 males and 6 females belong to 30–40 year age group. 8 males and 6 females belong to 41–50 age group and 15 males and 4 females were more than 50 years of age. The random blood sugars in diabetic case were 179 ± 42 mg/dl and control were 124 ± 12 mg/dl of blood. Severity of field defects were statistically significant in diabetic cases as compare to control group.

Early diagnosis of diabetes and regular ophthalmic examination with preventive measure and early treatment we can retard the progression of retinopathy.
