A Clinical study on Cystoid Macular Edema due to Vein Occlusion and Its Management

AIM OF THE STUDY: To compare the functional , anatomical and therapeutic outcome of patients with cystoid macular oedema due to retinal vein occlusion. MATERIALS AND METHODS: This iaa prospective study conducted at Uvea and Retina department, RIOGOH, Egmore. About 30 patients were analysed and followed upto 3months on regular basis and as and when required. OBSERVATIONS AND RESULTS: The mean age of presentationwas 53.2 ± 5.6 years with a male : female ratio of 1.9:1. Supero temporalbrvo was found to be the leading cause. The reduction in mean macular thickness was significant in patients. After treatment all patients had a significant 2 Snellen line visualimprovement. The correlation between macular thickness and visualacuity was weak positive in post treatment. There was no Increase in intraocular pressure noted. Hypertension was considered as a major association in developing vein occlusions. CONCLUSION: The fall in Mean macular thickness after IVTA and Intra vitrealAntiVEGFwas statistically significant in all patients analysed.The visual acuity improvement also was statistically significant (p < 0.0001) butcorrelation with macular thickness was weak positive. Intravitrealtriamcinolone acetonide is a promising therapy in refractory cystoidmacular edema in terms of safety and effective.
