Changes in visual field defects during 10-year follow-up for indocyanine green-assisted macular hole surgery.

Abstract

To determine whether the visual field defects detected within 3months of indocyanine green (ICG)-assisted inner-limiting membrane (ILM) peeling continue to worsen over longer periods. This was a retrospective observational case series. Four eyes with visual field defects that developed within 3years of ICG-assisted ILM peeling for a macular hole (MH) were examined yearly for 10years. The main outcome measures were the degree of mean deviation (MD) determined by Humphrey perimetry with the 30-2 SITA-Fast program and the best-corrected visual acuity (BCVA). Four patients were examined yearly for more than 10years, with a mean duration of follow-up of 139.5months (11.6years) and a range of follow-up of 137-156months (11.4-13years). The mean (±standard deviation) preoperative MD value was -4.99±3.26dB, and the mean postoperative MD values were -12.9±1.29dB after 1year, -14.1±0.75dB after 3years, and -12.73±2.65dB after 10years. The mean preoperative BCVA was 0.65±0.26 logarithm of the minimal angle of resolution (logMAR) units, and the postoperative BCVA was 0.21±0.07 logMAR units at 1year, 0.28±0.21 logMAR units at 3years, and 0.14±0.06dB logMAR units at 10years. The visual field defects detected soon after ICG-assisted ILM peeling continued to worsen for 3years, but not thereafter.
