Vitrectomie 25 g pour les membranes epiretiniennes et les syndromes de traction vitreo-maculaire: premiers resultats a 6 mois.

PURPOSE: to evaluate the safety and efficacy of the 25G transconjunctival vitrectomy in the treatment of epimacular membranes and vitreo-macular traction syndromes. METHODS: in this prospective study dealing with a consecutive series of 38 eyes with an epimacular membrane or a vitreo-macular traction syndrome, we recorded mainly the visual acuity the day before surgery, at day 1, 8 and 6 months after surgery, duration of surgery, and complications peroperatively, at day 1, 8, and at 6 months. RESULTS: 23 eyes had a 6-month follow-up (60%). Mean preoperative, day 1, day 8 and 6-month distance visual acuities were 0.3, 0.2, 0.4 and 0.5, respectively. Mean preoperative and 6-month near visual acuities were P4 and P3, respectively. At day 1 and day 8, 14/38 eyes (31%) and 33/37 eyes (89%), respectively, had a distance visual acuity equal or superior to the preoperative visual acuity. At 6 months, 16/23 eyes (70%) had a distance visual acuity improvement of at least 2 lines. 13/23 eyes (57%) had a near visual acuity improvement of at least 2 levels. Mean duration of surgery was 19 minutes (7 - 40'). Short-term complications were very few, and none were encountered afterwards. CONCLUSION: the 25G transconjunctival vitrectomy is a safe, effective, and convenient technique in the treatment of epimacular membranes and vitreomacular traction syndromes.
