Abstract :

INTRODUCTION: Diabetic retinopathy is a common of diabetes mellitus and the leading cause of vision loss in India which is now having epidemic of diabetes. The pathology of this disease is well characterized by microvascular lesions but also includes deficits in visual function, possibly as a consequence of retinal neurodegeneration. AIMS: • To examine the contrast sensitivity of the patients with type 2 DM • To compare the contrast sensitivity changes in patients with diabetic and with healthy subjects OBSERVATIONS AND RESULT Mean age group diabetic individuals was 51.42 with SD 9.18 & healthy individual Mean age is 52.96 with SD 9.09. 34 were females and 80 were males taken into the study. Sex ration in diabetic group was male: female was 2.5:1 and healthy individual is 2.1:1. There was no relation between age and CSF(contrast sensitivity function) in present study. Mean CSF of both Eyes of subjects with diabetes was 1.19 and with healthy individual was 1.50, Binocular CSF is more than that of uniocular CSF. Mean decimal equivalent visual acuity of diabetic subjects were 0.30 in right eye and 0.26 in left eye which were less than healthy individuals who had 0.21 and 0.15 in respected eye (p value <0.05) suggestive of there was significant relation between visual acuity and diabetic retinopathy patients. Mean decimal equivalent BCVA of diabetic patients was 0.15 and 0.14 in right and left eye where in healthy individuals had 0.07 and 0.05, p value <0.05, which shows significant relation between BCVA and DR. Mean FBS and PP2BS level among diabetic retinopathy had 158.63 and 265.21 and without diabetic retinopathy patients had 113.66 and 179.82 (p value <0.05), which suggest blood sugar levels had significant relationship with diabetic retinopathy. Duration of diabetes had no significant relation with contrast sensitivity. Blood pressure had no significant relationship with contrast sensitivity. CONCLUSION : Contrast sensitivity testing can be used as a screening method for early diabetic retinopathy changes as it decreases in early diabetic retinopathy changes.
