目的：评价白内障摘除联合玻璃体切除内界膜剥除术治疗非黄斑裂孔超高度近视性黄斑劈裂的疗效。
方法：回顾性分析。选取我院收治的非黄斑裂孔超高度近视性黄斑劈裂患者32例32眼，屈光度为-12.00～-20.00(平均-15.78±2.16)D。平均最佳矫正视力(LogMAR)4.1±0.4。所有患者均行白内障超声乳化吸出人工晶状体植入联合玻璃体切除内界膜剥除术，内界膜采用吲哚菁绿染色并顺利剥除，术毕进行气体填充。术后随访1～9(平均4.5)mo，观察术后视力及黄斑劈裂愈合效果。
结果：共30例30眼(94%)患者劈裂腔消失，视力较术前提高，视物变形改善。手术前后最佳矫正视力比较，差异具有统计学意义(t=-7.91，P<0.05)。
结论：白内障超声乳化吸出人工晶状体植入联合玻璃体切除内界膜剥除术是治疗非黄斑裂孔超高度近视性黄斑劈裂安全有效的手术方法，可有效保存视功能，不同程度提高患者的视力。

[Abstract]
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, P<0.05).
CONCLUSION: Phacovitrectomy with ILM peeling is useful in treating foveoschisis in ultra-high myopia with visual function preserving.
