Idiopathic Macular Hole Area to Foveal Avascular Zone Ratio and Its Effects on Visual Acuity Before and After Surgery.

ABSTRACT:

Purpose

This study investigates factors influencing visual acuity logarithmic minimum angle of resolution (logMAR) in idiopathic macular holes (IMH), with a focus on the foveal avascular zone (FAZ).

Methods

En face images from optical coherence tomography and optical coherence tomography angiography of 152 patients with stages 2, 3, and 4 IMH were analyzed. The minimum area (MA), base area, and FAZ of the macular hole were quantified, and the ratio of minimum area to FAZ (MFR) was calculated. In addition, central subfield thickness was extracted. Relationships between preoperative and postoperative visual acuity and these parameters, along with age, sex, axial length, and stage, were assessed using univariate and multivariate analyses.

Results

The study included 113 p
