Surgery for full-thickness macular hole in patients with idiopathic macular telangiectasia type 2

The authors report surgical outcomes of full-thickness macular hole repair in two patients with idiopathic macular telangiectasia in a non-comparative case series. Both patients underwent pars plana vitrectomy with indocyanine green-assisted internal limiting membrane peeling and injection of 16% C(3)F(8) gas. Patients were imaged with optical coherence tomography (OCT) before and after surgery. The first patient demonstrated macular hole closure on examination and OCT with visual improvement from 20/50 preoperatively to 20/30 after macular hole surgery and subsequent cataract surgery. The second patient's hole closed per OCT immediately after surgery but reopened 4 months later, and visual acuity remained 20/70. Macular hole surgery may be an effective treatment in patients with idiopathic macular telangiectasia and full-thickness macular holes and should be further investigated.
