Significance of preoperative external limiting membrane height on visual prognosis in patients undergoing macular hole surgery

Geenen, Caspar, Murphy, Declan C., Sandinha, Maria T., Rees, Jon and Steel, David H. W. (2019) Significance of preoperative external limiting membrane height on visual prognosis in patients undergoing macular hole surgery. RETINA, 39 (7). pp. 1392-1398. ISSN 0275-004X

Item Type: Article


To investigate the association between the vertical elevation of the external limiting membrane (ELM) and visual outcome in patients undergoing surgery for idiopathic full-thickness macular hole.
Retrospective observational study of a consecutive cohort of patients undergoing vitrectomy to treat macular hole. The greatest vertical height of the central ELM above the retinal pigment epithelium (ELM height) was measured on spectral domain optical coherence tomography preoperatively. The relationship of ELM height to other preoperative and postoperative variables, including macular hole width and height, and visual acuity was analyzed.
Data from 91 eyes of 91 patients who had undergone successful hole closure were included. The mean ELM height was 220 μm (range 100–394). There were significant correlations between the ELM height and the diameter of the hole, hole height, and worsening preoperative visual acuity. For holes less than 400 μm in width, better postoperative visual acuity was significantly predicted by a lower ELM height.
The ELM height varies widely in idiopathic macular hole. It is higher in eyes where the hole is wider and also when the hole itself is higher. For holes of less than 400 μm in width, a lower ELM height is a strong independent predictor of a good postoperative outcome.
