Parameters affecting the anatomical and functional success of macular hole surgery

Abstract

Aim: To evaluate the effect of preoperative Spectral Domain Optical Coherence Tomography (SD-OCT) parameters on macular hole surgery (MHS) and their predictive value for postoperative best corrected visual acuity (BCVA).
 Materials and Methods: This retrospective study included 30 eyes of 30 patients with macular hole (MH). All patients underwent pars plana 23-gauge vitrectomy. A detailed macular analysis including MH minimum diameter (MD), base diameter (BD), opening diameter (OD), height, nasal arm (NA), temporal arm (TA), macular hole index (MHI), diameter hole index (DHI), tractional hole index (THI), hole form factor (HHF), macular hole area (MHA), and macular hole volume (MHV) were performed preoperatively. Presence of inner segment–outer segment (IS/OS) line, external limiting membrane (ELM), and cyst was noted postoperatively. Relationships between these parameters and postoperative BCVA were evaluated.
 Results: The study group comprised 25 (83.3%) women. Mean pre and postoperative BCVA values were 0.924±0.320 and 0.487±0.287 logMAR, respectively. BCVA improved significantly after MHS (p
