Agreement between optical coherence tomography and fundus fluorescein angiography in post-cataract surgery cystoid macular edema

Abstract

Purpose: To evaluate the agreement between optical coherence tomography (OCT) and fundus fluorescein angiography (FFA) regarding the detection of cystoid macular edema (CME) following cataract surgery. Methods: Retrospective comparative observational series of 25 eyes with suspected CME. Patients with low visual acuity and alterations in fundus biomicros-copy after cataract surgery underwent OCT scanning followed by FFA on the same visit. The diagnosis of CME was established considering fluo-rescein leakage on FFA and retinal thickness andor cystoid spaces and/ or subretinal fluid on OCT. Results: Twenty-five eyes of 25 patients were enrolled. Twenty-two eyes had similar results on both OCT and FFA, of which 15 eyes had CME and 7 eyes had no CME. Two eyes had CME detected only by FFA and one eye only by OCT. The agreement between the two examinations was good (Kappa = 0.7331; p=0.0001) with no tendency to have neither more positive nor negative findings (p=1.0). Conclusion: According to these preliminary data, OCT seems to be as effective as FFA to detect CME with a good agreement between the two techniques.^ipt
