Relationship between peeled internal limiting membrane area and anatomic outcomes following macular hole surgery: a quantitative analysis

purpose To quantitatively evaluate the effects of peeled internal limiting membrane (ILM) area and anatomic outcomes following macular hole surgery using spectral domain optical coherence tomography (SD-OCT). Methods. Forty-one eyes in 37 consecutive patients with idiopathic, Gass stage 3-4macular hole (MH) were enrolled in this retrospective comparative study. All patients were divided into 2 groups according to anatomic success or failure. BasalMHdiameter, peeled ILMarea, andMHheight were calculated using SD-OCT. Other prognostic parameters, including age, stage, preoperative BCVA, and symptom duration were also assessed. Results. Thirty-two cases were classified as anatomic success, and 9 cases were classified as anatomic failure. Peeled ILM area was significantly wider and MH basal diameter was significantly less in the anatomic success group (?? = 0.024 and 0.032, resp.). Other parameters did not demonstrate statistical significance. Conclusion.The findings of the present study show that the peeled ILM area can affect the anatomic outcomes of MH surgery.
