Abstract EN
Purpose.
Internal limiting membrane (ILM) peeling is important for macular hole (MH) surgery but may have secondary effects visible on spectral domain optical coherence tomography (OCT) and multifocal electroretinography (mfERG).
We relate integrity of inner and outer macular layers with functional results with mfERG.
Methods.
Nonrandomized prospective study of 33 consecutive eyes of 33 patients with macular hole who underwent vitrectomy with ILM peeling.
Best-corrected visual acuity was assessed, and integrity of external layers was measured using OCT.
Each component of mfERG, N1 and P1 amplitude and latency, was also measured.
Results.
All eyes showed macular hole closure.
Visual acuity improved from 20/400 to 20/40 in the Snellen visual acuity chart (P<0.001), and OCT external lines were intact in 19 eyes and disrupted in 14 eyes.
Postoperatively, N1 and P1 amplitudes in ring 1 increased compared to preoperative values (P<0.001 for both).
Latency remained delayed for both N1 and P1 wave.
In the group of 19 eyes with integrity of outer retinal layers, N1 amplitude in ring 1 was superior to the group of 14 patients with disrupted outer retinal layers (P=0.042).
Conclusions.
In macular hole surgery, structure analysis in OCT is one of the important outcomes for the retinal surgeon.
Functional results are parallel with anatomic results, but visual gain is limited.
The limited recovery in mfERG suggests an alteration of retinal physiology that could explain limited vision recover.
