Abstract

Purpose:: To assess the relationship between the size of idiopathic macular hole and changes in visual function by pars plana vitrectomy.

Methods:: Subjects were 15 eyes of 14 patients (age 67.0 ± 3.5 years, mean ± SD) undergoing primary vitrectomy and inner limiting membrane peeling for idiopathic macular hole. On optical coherence tomography (OCT), macular hole diameter was determined both at the level of retinal pigment epithelium (base diameter) and the minimal extent of the hole (minimum diameter). Clinical data were collected including best corrected visual acuity, contrast sensitivity (CSV-1000, Vector vision), and the degree of metamorphopsia (M-CHARTS, Inami) before and 3 months after surgery.

Results:: Minimum diameter of macular hole was significantly correlated with preoperative contrast sensitivity (r = 0.63, p < 0.05), preoperative metamorphopsia (r = 0.54, p < 0.05), changes in logMAR best corrected visual acuity by surgery (r = -0.63, p < 0.05), changes in contrast sensitivity by surgery (r = -0.87, p < 0.001), and improvement of metamorphopsia by surgery (r = 0.75, p < 0.005). Base diameter of macular hole was significantly correlated with preoperative contrast sensitivity (r = 0.72, p < 0.05) and changes in contrast sensitivity by surgery (r = -0.80, p < 0.005).

Conclusions:: Minimum diameter of macular hole had strong relationship with contrast sensitivity and the severity of metamorphopsia. Base diameter of macular hole had correlation with contrast sensitivity. The current study represents the first report of significant association of macular hole size with contrast sensitivity.

Keywords: macular holes • contrast sensitivity • imaging methods (CT, FA, ICG, MRI, OCT, RTA, SLO, ultrasound)
