AIM: To analyze the results of phacovitrectomy with internal limiting membrane(ILM)peeling to treat foveoschisis in ultra-high myopia. METHODS: Totally 32 eyes of 32 ultra-high myopia patients with foveoschisis were selected retrospectively. The preoperative refractive errors ranged from -12.00D to -20.00D with the mean of -15.78±2.16D. The best corrected visiual acuity(BCVA)were converted to LogMAR acuity, and the average BCVA was 4.1±0.4. Conventional phacovitrectomy with ILM peeling by ICG dying were performed. Gas tamponade were performed to end the operation. The BCVA and the foveoschisis cavity were observed by 1-9mo after the surgery, with the mean of 4.5mo. RESULTS: The foveoschisis cavity of 30 eyes were healed with BCVA increased and visual distortion alleviated distinctly(94%)(t=-7.91, PCONCLUSION: Phacovitrectomy with ILM peeling is useful in treating foveoschisis in ultra-high myopia with visual function preserving.

Pathological myopia are often complicated by a series of pathological changes in fundus including foveoschisis, which can lead to visual dysfunction when processing with retinal detachment, macular hole, epiretinal membrane and vitreoretinal traction diseases. According to the current knowledge, the main mechanism of foveoschisisi might be attributed to the impaired macular structure and function caused by a variety of traction on the retinal and retina poor condition. Surgical treatments have been reported to be effective in treating foveoschisis, however, the indications and surgical procedures are still controversial. In this article, we reviewed the clinical features, diagnosis, treatment strategies and prognosis of pathological myopia foveoschisis.

AIM: To evaluate the efficacy and safety of vitrectomy combined with internal limiting membrane(ILM)peeling for treating foveoschisis in high myopia.METHODS: Thirty high-myopia patients(30 eyes)with foveoschisis from March 2011 to March 2013 were divided two groups: the treatment group(16 eyes)was treated with vitrectomy combined with ILM peeling, and the control group(14 eyes)was treated only with vitrectomy. The foveoschisis reattachment and and best spectacle-correction were measured preoperatively and 2mo after surgery.RESULTS: The improvement of foveoschisis reattachment and best spectacle-correction in the treatment group was significantly better than those in the control group(P<0.05).CONCLUSION: Vitrectomy combined with ILM peeling is a safe and effective treatment for foveoschisis in high myopia.
