A Clinical Study on Correlation of Optical Coherent Tomography and Fundus Fluorescein Angiography Finding in Diabetic Macular Edema

Diabetic macular edema is a major cause of visual morbidity in patients with Diabetes. It usually results from breakdown of inner blood-retinal barrier. Early detection of Retinal abnormalities is important in preventing Diabetic macular edema and subsequent visual loss. AimTo know the correlation of Optical coherent tomography and Fundus fluorescein angiography finding in diabetic macular edema. Materials and MethodsThis was a cross sectional study done in Regional institute of ophthalmology, Gauhati Medical College. All patients who were diagnosed as CSME underwent complete ophthalmological examination and subjected to OCT and FFA. ResultsA total of 50 patients were studied. Among 92 eyes with CSME, OCT shows 54 eyes [58.69 %] having sponge like retinal thickening, 29 eyes [31.52 %] having cystoids pattern, Serous RD, in 6 eyes [6.52 %] and vitreomacular traction in 3 eyes [3.26 %]. FFA in eyes with CSME showed, focal leakage in 38 eyes [41.30 %], Diffuse leakage in 24 eyes [26.08 %], 27 eyes [29.34 %] showed both focal and diffuse leakage, whereas 3 eyes [3.26 %] showed ischemic maculopathy pattern. ConclusionThere is a significant (pless than0.0001) correlation between mean OCT (foveal thickness) with the types of maculopathy detected by FFA.
