The few published studies that exist on the surgical outcomes of full-thickness macular hole (FTMH) repair in Macular Telangiectasia (MacTel) Type 2 report poor rates of hole closure of around 30%. This study is the largest case series of patients with FTMH in MacTel Type 2 and describes an 80% hole closure rate.

To describe the outcomes of four patients who underwent surgery for FTMH associated with MacTel Type 2.
A retrospective review of clinical, surgical, and imaging data of five eyes in four patients with MacTel Type 2 FTMH who underwent pars plana vitrectomy (PPV) with internal limiting membrane (ILM) peeling and 30% SF or 15% CF gas tamponade within 3-9 months of initial vision decline.
Visual acuity (VA) at the time of surgery ranged from 20/50 to 20/200. Successful hole closure was achieved in four out of five eyes, and final VA ranged from 20/20 to 20/40 at follow-up visits greater than 20 months postoperatively. The single eye that did not achieve hole closure had a final VA of 20/60.
Our case series describes higher hole closure rates and better final VA than previously published reports for macular hole surgery in patients with MacTel Type 2 FTMH.
关于黄斑部毛细血管扩张症2型（MacTel 2）全层黄斑裂孔（FTMH）修复手术结果的已发表研究较少，报告的裂孔闭合率约为30%，效果较差。本研究是MacTel 2型FTMH患者最大的病例系列，描述的裂孔闭合率为80%。

描述4例接受与MacTel 2型相关的FTMH手术患者的手术结果。
回顾性分析4例MacTel 2型FTMH患者5只眼的临床、手术和影像学数据，这些患者在视力首次下降后3 - 9个月内接受了玻璃体切割术（PPV）联合内界膜（ILM）剥除，并使用30%的硅油或15%的全氟丙烷气体填充。
手术时的视力范围为20/50至20/200。5只眼中有4只成功实现裂孔闭合，术后随访超过20个月时，最终视力范围为20/20至20/40。未实现裂孔闭合的那只眼最终视力为20/60。
我们的病例系列显示，与之前发表的MacTel 2型FTMH患者黄斑裂孔手术报告相比，裂孔闭合率更高，最终视力更好。
