Purpose: To report the clinical features of tractional internal limiting membrane (ILM) detachment in highly myopic eyes with posterior staphyloma.
Design: Observational case report.
Methods: We reviewed the optical coherence tomography images of 249 eyes in the high myopia clinic. ILM detachment was observed in six eyes (2.4%). We investigated the clinical feature of this finding.
Results: Myopic foveoschisis (MF) was present in four of the six eyes (67%) (six patients, two men and four women; mean age, 57.3 years). The mean axial length was 29.3 mm and the mean refractive error was -15.0 diopters. The best-corrected visual acuity levels ranged from 20/400 to 20/13.
Conclusions: Rigidity of the ILM seems to cause tangential traction and results in a major cause of a disease specific to high myopia; that is, MF.
