PURPOSE:: To evaluate the outcome of vitrectomy with internal limiting membrane peeling and no gas tamponade in the treatment of eyes with myopic foveoschisis. METHODS:: Medical records of 10 eyes of 9 consecutive patients with myopic foveoschisis without macular hole treated by vitrectomy were reviewed. RESULTS:: The patientsÊ1/4 refractive error was-4.00 diopters to-34.00 diopters, and axial length was 28.38 mm to 35.90 mm. Six eyes had foveal retinal detachment with retinoschisis. All cases were treated by vitrectomy with internal limiting membrane removal without gas tamponade. The mean preoperative best-corrected visual acuity was 0.61 ± 0.42 in logarithm of the minimum angle of resolution units (Snellen equivalent of 20/82). Myopic foveoschisis was reduced in 8 eyes (80%) with a single surgery. Two eyes without improvement developed a postoperative macular hole and were treated by additional vitreoretinal surgery. All 10 eyes showed anatomical repair, and 5 eyes showed improvement in best-corrected visual acuity to 0.47 ± 0.48 (Snellen equivalent of 20/60), by 17 months after the initial surgery. CONCLUSION:: Vitrectomy with internal limiting membrane peeling and no gas tamponade can effectively treat some cases of myopic foveoschisis, suggesting that tractional forces at the vitreoretinal interface may contribute to the pathogenesis of myopic foveoschisis, thereby avoiding gas tamponade.
