Restoration of the Ellipsoid Zone and Visual Prognosis at 1 Year after Surgical Macular Hole Closure

Abstract EN

Purpose.

To evaluate the restoration of the ellipsoid zone (EZ) and its influence on visual prognosis 1 year after surgical macular hole (MH) closure.

Method.

Subjects were patients with stage 2, 3, or 4 idiopathic MH who underwent primary vitrectomy that resulted in successful hole closure.

Nineteen eyes with both EZ disruption with foveal detachment and a continuous external limiting membrane on optical coherence tomography during the early postoperative period were included in this study.

Result.

EZ disruption was restored in 10 eyes (53%, Group A) and remained in 9 eyes (47%, Group B) at 1 year after surgery.

In Group B, the diameter of the residual EZ disruption was 54.7 ± 33.1 μm.

LogMAR visual acuity (VA) 1 year after surgery was significantly better than preoperative VA in each group (Group A: - 0.007 ± 0.102 ; P < 0.001 ; Group B: 0.051 ± 0.148 ; P < 0.001 ), but there was no significant difference between the 2 groups ( P = 0.332 ).

There was no significant correlation between logMAR VA and EZ disruption diameter at 1 year after surgery.

Conclusion.

EZ was restored in 53% of eyes at 1 year after surgical closure of idiopathic MH.

Mean residual EZ disruption diameter was 54.7 ± 33.1 μm.

Neither resolved nor residual EZ disruption influenced postoperative VA.
