Abstract

Introduction

Diabetic retinopathy (DR) mainly in Type 2 diabetics is one of the major causes of permanent vision loss in working population.¹ In DR, before significant visual loss patient may suffer other disturbances such as waviness, blurring, relative scotoma which is not assessed by routine examination. Therefore, suspicion and detection of early signs of neuro degeneration could be beneficial in preventing vision loss and deciding appropriate therapeutic approach in the management of diabetic retinopathy which is achieved by integration of retinal details by fundus related perimetry (microperimetry) & correlating it with the precise location of oedema or thickness by OCT.²   

Spectral domain OCT is a newer-generation high-resolution OCT with the advantages of high-speed data acquisition, three-dimensional reconstruction of acquired retinal images, and improved visualization of retinal architecture, layer by layer whereas microperimetry offers the possibility to obtain an exact fundus related quantification of retinal sensitivity. Therefore, this study will help us to identify, among diabetic patients, a population at higher risk of developing vision threatening retinopathy.³
