Purpose: To compare the sensitivity of optical coherence tomography(OCT) and fundus fluorescein angiography (FFA) for detection of cystoid macular oedema (CME).
Methods:Prospective comparative observational study on 50 patients with suspicious biomicroscopic picture suggesting CME selected.FFA and OCT performed on same day. Diagnosis by OCT was based on retinal thickness, cystoid spaces and subretinal fluid. In FFA CME diagnosis was based on mild to severe perifoveal hyperfluorencence. Images were obtained from dye injection time to late venous stage and studied. CME was identified by accumulation of dye in petalloid or honeycomb like pattern. Purpose was the comparison between FFA and OCT in diagnosis of CME.
Result: The common causes of CME were retinal vein occlusion (63%), diabetic retinopathy (22%), posterior uveitis (4%) & ARMD (4%). CME was undetected by FFA in 19%-RVO, 33%-ARMD, 33%-DR.
Conclusion:OCT showed more sensitivity than FFA in detecting CME and also late complications.
