Treatment of Vitreomacular Traction with Intravitreal Injection of Perfluoropropane

Abstract

Purpose: To evaluate the effect of one intravitreal injection of expansile gas in the treatment of vitreomacular traction (VMT). Methods: A retrospective review of eyes with VMT treated with singl injection of 0,3 ml of 100% C3F8 gas was performed. The procedure was performed on an outpatient basis under topical anesthesia. Results: Twelve consecutive patient (14 eyes) with symptomatic VMT underwent pneumatic vitreolysis. Mean extend of vitreomacular adhesion was 490,5 µm (408-751). A posterior vitreous detachment developed in 13 eyes (92,9 %) after a single gas injection, in 11 eyes (84,6 %) during the first month of follow-up, in 2 eyes within two month of injection. Mean baseline and last BCVA were 0,5 (0,16-0,18) and 0,67 (0,2-1,0) respectively (p < 0,001). Mean folow-up time was 5,8 (1-16) months. The procedure was also successful in two eyes, which where previously unsuccessfuly treated with ocriplasmin. One eye formed a macular hole. There were no other complication. Conclucion: Intravitreal injection of C3F8 is an effective, safe and inexpensive therapy of vitreomacular traction.
