[Idiopathic vitreomacular traction syndrome. Vitrectomy results].

PURPOSE

Evaluate the visual results, the complications and the prognosis factors of surgery for idiopathic vitreomacular traction syndrome.

METHODS

We retrospectly reviewed 29 consecutive eyes that had undergone pars plana vitrectomy and posterior epiretinal membrane peeling for idiopathic vitreomacular traction syndrome.

RESULTS

The mean follow-up after surgery was 17.7 months. Among the 29 cases, 21 were phakic. Visual acuity improved by 2 lignes or more in 72.4% of the cases and the mean improvement was 2.7. Eyes with preoperative visual acuity of 0.25 or more had better postoperative vision than the others (0.42vs0.65;p=0.006). During the follow-up, 10 patients underwent phacoemulsification and posterior chamber implantation (47.6%). The mean visual acuity of these 10 cases was poorer than the mean visual acuity of the 8 pseudophakic patients that underwent vitrectomy (0.45vs0.61;p=0.046). Five recurrences of epiretinal membrane were observed (17.2%).

CONCLUSIONS

Surgical treatment of vitreomacular traction syndrome improves visual acuity in most of cases. Further studies with optical coherence tomography are necessary to understand the pathogenic mechanisms of vitreomacular interface syndromes.
