To study the functional and anatomical effects of internal limiting membrane (ILM) peeling in macular hole surgery with a minimum follow-up of 10 years.Retrospective study of patients who underwent successful macular hole surgery prior to 2010. All patients underwent vitrectomy and ILM peeling after staining. Functional assessment included measurement of visual acuity and retinal sensitivity using microperimetry (NIDEK MP-3) as well as a subjective visual function questionnaire. Anatomical assessment was based on evaluation of the macular region and optic nerve using spectral domain optical coherence tomography (SD-OCT) with comparison to the fellow eye.Fourteen women and five men were included. Visual acuity of operated eyes (0.07±0.08logMar) was not significantly different from that of fellow eyes (0.04±0.08logMar) (P=0.10). The mean retinal sensitivity of the operated eyes was 25.1±1.9dB with no difference from the fellow eyes 25.2±1.6dB (P=0.82). However, 2 patients exhibited 2 relative scotomas10dB. On questioning, 3/19 patients (16%) described a disturbing scotoma in monocular vision, while 11/19 (58%) described metamorphopsia, and 3 subjectively assessed their visual loss at more than 60%. The external limiting membrane was present and intact in all patients, and the ellipsoid zone was restored in 16/19 patients (84%). The cone interdigitation zone was intact in 9 patients, altered in one patient and not interpretable in 9 patients. Retinal optic nerve fiber layer thickness showed a moderate loss of fibers in the operated group 95.9±9.5 versus 101.5±10.9 (P=0.001) in the fellow eyes. The ganglionic complex thickness in the operated eyes (90.1±8.3) was not significantly different from that of fellow eyes (91.9±8.8) (P=0.37).ILM peeling in macular hole surgery induces anatomical changes in the inner layers of the retina, still visible on SD-OCT 10 years after the procedure. However, this remodeling of the inner layers does not appear to have significant deleterious effects on patients' retinal sensitivity or vision. |
