Surgical Outcomes in Macular Telangiectasia Type 2-Related Macular Holes: A Report on Four Patients

INTRODUCTIONThe 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. PURPOSE/. AIMTo describe the outcomes of four patients who underwent surgery for FTMH associated with MacTel Type 2. METHODSA 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% SF6 or 15% C3F8 gas tamponade within 3-9 months of initial vision decline. RESULTSVisual 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. CONCLUSIONOur 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.
