Purpose: To evaluate the effect of one intravitreal injection of expansive gas in the treatment of vitreomacular traction (VMT). Method: Retrospective evaluation of results of treatment of VMT with the aid of a single intraocular application of 0.3 ml 100% C3F8 gas. The procedure was performed in outpatient treatment under topical anaesthesia. Results: Twelve patients (14 eyes) underwent pneumatic vitreolysis. The mean extent of vitreomacular adhesion was 490.5 µm (408-751). Detachment of the posterior vitreous membrane occurred in 13 eyes (92.9%) after one injection, in 11 of these eyes this took place during the first month of observation (84.6%), in the other two eyes within two months of the procedure. Visual acuity improved from a baseline mean value of 0.50 (0.16-0.18) to 0.67 (0.2-1.0) (p < 0.001). The procedure was also successful in two eyes in which a previous attempt to release VMT with the aid of ocriplasmin had been unsuccessful. In one eye macular hole developed. We did not record any other complications in this cohort. Conclusion: Intravitreal application of C3F8 represents an effective, safe and inexpensive method of treatment of VMT.

Odrobina D., Michalewska Z., Michalewski J., et al.: Long-term evaluation of vitreomacular traction disorder in re are few published cohorts, and the effectiveness appears to be rather lower in comparison with C3F8, which could be in connection with the shorter duration of its effect. Day et al. recorded release of VMT after the application of SF6 in 55.6% of eyes (4). Čokl et al. compared the effect of both gasses in a prospective study (3). With the aid of C3F8 they achieved release of VMT in 62% of eyes, whereas after application of SF6 traction was released in only 21.4% of eyes. C3F8 was more effective in eyes with an extent of vitreomacular adhesion of > 500 µm (p = 0.001), in the case of adhesions of lesser extent the effect of both gases was comparable. Experiences with the use of SF6 were published also by Buzzacco. Release of VMT was achieved in 83% of eyes. However, the cohort numbered only 6 eyes (1).
