Posterior retinal function following macula-off retinal detachment
PURPOSE: Visual functional macular study of patients with retinal detachment (RD) macula-off with successful reattachment by the conventional scleral buckling procedure. SETTING: Visual acuity (VA) and visual field (VF) tests may be imperfect visual function tests for RD. METHODS: Fifteen patients with primary rhegmatogenous RD with macular involvement, underwent, after 4 months, to a complete ophthalmological exams, including VA, optical coherence tomography (OCT), mutifocal electroretinogram (mfERG) and microperimetry (MP-1). Nonparametric statistical analysis was used to compare results from the affected and unaffected eye. The mfERG and MP-1 responses, were grouped by four successive rings from center to periphery. The P1 amplitudes and implicit times (mfERG), macular thickness (OCT), microperimetry (MP-1) and VA were compared between the affected and unaffected eye. RESULTS: Statistical significant difference was observed between MP-1 and P1 amplitudes and implicit times from de mfERG comparing affected and unaffected eye in all rings except for P1 implicit times in ring 1 (P=0,167). CONCLUSIONS: P1 amplitudes seem to correlate better with photoreceptor function than implicit times. OCT, mfERG and MP-1 are useful tools to evaluate the recovery of posterior retinal functional after retinal detachment surgery.
