EVALUATION OF THE EFFECTIVENESS OF TREATMENT WITH INTRAVITREAL TRIAMCINOLONE IN CYSTOID MACULAR EDEMA SECONDARY TO RETINAL VEIN OCCLUSION

Abstract

PURPOSE. To evaluate retinal functional improvement by means of visual acuity after intravitreal triamcinolone in patients affected by cystoid macular edema secondary to retinal vein occlusion. Twenty-six consecut METHODS. ive patients affected by retinal vein occlusion complicated by cystoid macular edema were enrolled in this prospective interventional study. All patients underwent a baseline complete ophthalmological evaluation as well as retinal angiography and OCT examination. Baseline functional evaluation showed mean visual acuity of 0.63±0 RESULTS. .42 LogMAR after treatment, at day 30 we found, 0.43±0,.8 Log MAR (p<0.05, compared to baseline) at day 90, we found 0.44±0.32 (p<0.05), at day 180, we found 0.41±0.31 (p<0.05). Baseline morphological evaluation showed a central retinal thickness (CRT) of 398.21±181.65 μm after treatment; we found a CRT of 222.64±95.21 μm at day 30 (p<0.05, compared to baseline), 307.50±120.25 μm (p<0.05) at day 90, and 294.93±135.86 μm (p<0.05) at day 180. About 15.3% patients showed already at month 3 a recurrence of macular edema. They underwent a retreatment before month 6 as for treatment guidelines. Our analysis showed increase in retinal function in the early phases of the f CONCLUSION. ollowup. Visual Acuity showed a stronger correlation in macular edema reabsorption, better underlying progressive functional recovery and increase in quality of vision and life for the patients.
