A STUDY ON CHANGES IN RETINAL SENSITIVITY AMONG DIABETIC PATIENTS

Journal Title: International Journal of Basic and Applied Physiology - Year 2018, Vol 7, Issue 1

Abstract

There is an increasing problem burden of diabetes with increasing age; adult diabetics are also at risk of vision threatening retinopathies. The absolute number of the over 60 population in India will increase from 76 million in 2000 to 137 million by 2021. Diabetic Retinopathy is the most common ocular manifestation of diabetes. Patients with diabetic retinopathy have a sensitivity loss in the mid-peripheral visual field detected by white-on-white Perimetry; this loss has been correlated with the retinal area of non-perfusion in proliferative diabetic retinopathy (PDR). Methods: 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 (C.G.) from August 2014 to July 2015. Study subject were selected by simple random sampling, those fulfilling inclusion criteria. 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. All patients underwent complete clinical examination. 42 eyes were examined in each group one eye per patient was assessed in all subjects. Eye examination includes Best-corrected visual acuity, refraction, intraocular pressure, Slit lamp examination & Humphrey Visual Field Automated Perimetry 30-2 test were performed. Results: Out of 42 diabetics or cases 26(61.91%) were male while 16 patients (38.09%) were female. In diabetic cases 3 males and 6 females belong to 30-40 year age group. Mean age of diabetic was 50.69± 10.69 years in which male was 53.69 ± 10.69 years and female was 45.81 ± 9.01 years. 11 (26.19%) males and 8 (19.05%) females had diabetes of less than or equal to 5 years. Maximum cases 19(45%) had diabetes of less than or equal to 5 years. 64.28% diabetic cases while 43.24% control had decreased vision means visual acuity < 6/6. The mean Intraocular Pressure in diabetic males was 17 mm of Hg. The mean Intraocular Pressure in diabetic females 16 mm of Hg. In 42 diabetic cases, lens opacity present in 29 (69 %) cases while in control group it was present in 23(55%) eyes. Retinal sensitivity was statistically lower in diabetic case as compare to control. Conclusion: The primordial, primary as well as secondary preventive measure by periodic ophthalmic examination helpful in early diagnosis and appropriate management of diabetic Retinopathy cases.
