Abstract

Purpose: To investigate whether preoperative retinal function as measured by full field ERG and mfERG correlates to postoperative visual acuity after macular hole surgery

Methods: 19 consecutive patients underwent macular hole surgery. Standard pars plana vitrectomy with removal of the ILM was performed and intraocular gas tamponade with (C2F6) gas-air mixture followed by a face-down position for at least 5 days. All patients were examined with ETDRS chart, full-field electroretinography (Espion), multifocal electroretinography (mfERG Veris 6) and optical coherence tomography (OCT) preoperatively, at 6 weeks and at 6 months after surgery.

Results: : In all patients longstanding alteration of cone and rod function reflected by mfERG and full field ERG were verified 6 months after surgery. A prolonged cone 30Hz flicker implicit time in the full field ERG and the cone implicit time in the sum mfErg before surgery was significantly correlated to the ETDRS visual acuity 6 months postoperatively p > 0.05; (Wilcoxon signed rank test nonparametric test).

Conclusions: Preoperative evaluation of retinal function with mfERG and fullfield ERG enhances understanding of the retinal recovery process after macular hole surgery. The cone implicit time in the fullfield 30Hz flicker ERG and the sum mfERG are valid predictors for long-term visual outcome, which may be useful for patient selection prior to surgery.
