Autologous neurosensory retinal flap for closure of refractory macular hole in a patient with macular telangiectasia

Abstract

Purpose: This study explores autologous neurosensory autograph for a patient with a chronic full-thickness macular hole (FTMH) and idiopathic macular telangiectasia type 2 (IMT2). Observations: The patient had a chronic 1355 μm FTMH and best corrected visual acuity (BCVA) of 2 logMAR units after two unsuccessful attempts to close the macular hole. Following a 25-gauge vitrectomy, a 2-disc diameter neurosensory autograft from the supertemporal retina was mobilized and secured with perfluoro-N-octane (PFO) tamponade. After being postured supine for one week, the PFO was exchanged for silicone oil. Two months later, silicone oil was exchanged for 20% sulphur hexafluoride (SF6). Conclusions and importance: The graft achieved anatomical and functional success with BCVA of 0.6 logMAR units. This case supports autologous neurosensory autograph as a technique for achieving closure of chronic macular holes refractory to conventional treatment.
