Efficacy and retention times of intravitreal triamcinolone acetonide for macular edema

摘要

Purpose To evaluate the retention of intravitreal triamcinolone acetonide (TA) particles and the efficacy of TA therapy for patients with cystoid macular edema in branch retinal vein occlusion (BRVO) or diabetic macular edema (DME). We monitored the TA particles until absorption from the vitreous cavity was complete. The correlation between the intravitreal retention time of TA and its efficacy was evaluated based on central macular thickness (CMT).
