Abstract:

Objective To evaluate visual and anatomical outcomes in patients with myopic foveoschisis who underwent vitrectomy and internal limiting membrane (ILM) peeling with room air tamponade. Design Retrospective case series. Participants 24 eyes of 20 patients with myopic foveoschisis were included. Methods Pars plana vitrectomy (25 Gauge) and ILM peeling with room air tamponade were performed in all patients. 6 eyes which combined with cataract were simultaneously accepted phacoemulsification with intraocular lens implantation. All recruits were accepted best-corrected visual acuity (BCVA) testing (logMAR), slit lamp, indirect ophthalmoscope and optical coherence tomography scans. Central foveal thickness (CFT) detected by OCT in pre-operation and 3, 6 months after surgery. According to the ETDRS, CFT was recorded in 5 areas (C, central; S, superior; I, inferior; N, nasal; T, temporal). All patients completed follow-up for more than 3 months (20.54±38.63 weeks). Main Outcome Measures BCVA and CFT. Results Preoperative and postoperative CFT was (1.41±0.51) and (0.58±0.69) LogMAR units respectively (P=0.001). The CFT of the postoperative eyes in the areas of C, S, I, N,T (233.09±78.72 μm, 260.18±41.04 μm, 260.36±29.85 μm, 289.41±28.38 μm, 237.55±53.57 μm) were significantly thinner than the corresponding areas of preoperative eyes (452.36±111.28 μm, 425.05±78.39 μm, 415.10±74.43 μm, 404.55±56.03 μm, 451.45±93.49 μm)(all P=0.000). Conclusion Vitrectomy combined ILM peeling and room air tamponade results in favorable visual and anatomical outcomes in myopic foveoschisis.
