Comparative Study of 27-Gauge Versus 25-Gauge Vitrectomy With Air Tamponade in the Treatment of Myopic Foveoschisis

BACKGROUND AND OBJECTIVE: To compare the surgical outcome of 27-gauge pars plane vitrectomy (PPV) with 25-gauge PPV and evaluate the efficacy of air tamponade for the treatment of myopic foveoschisis (MF). PATIENTS AND METHODS: Sixty eyes of 60 consecutive patients were recruited to undergo vitrectomy, internal limiting membrane (ILM) peeling, and air tamponade for treatment of MR These eyes were divided into two groups: the 27-gauge group (n = 29) and the 25-gauge group (n = 31). RESULTS: There were no significant differences in the mean operating time (P = .32), the mean time for vitrectomy (P = .20), and the suturing rate (P = .46) between the 27-gauge group and the 25-gauge group. At the final follow-up, anatomical resolution rate did not differ between the two groups (P = .65). CONCLUSION: The 27-gauge vitrectomy system is as efficient and feasible as the 25-gauge system for the treatment of MF. Air tamponade can provide good postoperative anatomic resolution of MF.
