Abstract

AIMS—To determine if postoperative visual outcome after successful macular hole surgery can be predicted with preoperative scanning laser ophthalmoscope (SLO) microperimetry.
METHODS—A prospective non-comparative study of 16 eyes in 15 patients examined before the surgery.
RESULTS—Visual outcome following macular hole surgery correlated with the "maximum parahole sensitivity", the highest intensity of stimulus to which the patient did not respond to any of the stimuli around the hole. Preoperative visual acuity, duration of the symptoms, size of the macular hole, and the "minimum parahole sensitivity", the lowest intensity to which the patient responded to all the stimuli around the hole, did not correlate significantly with postoperative visual acuity.
CONCLUSION—Preoperative assessment of patients using SLO microperimetry is a good predictor of visual outcome after macular hole surgery.

The actual procedure of SLO microperimetry to evaluate macular holes. (A) When the stimuli were presented at 20 dB, two different coloured spots that the patient recognised (green) and did not recognise (red) are shown. (B) The intensity was decreased until the patient did not recognise all stimuli around the macular hole, which was defined as the "maximum parahole sensitivity" (22 dB). (C) Thereafter, intensity was increased until the patient recognised all stimuli around the macular hole, which was defined as the "minimum parahole sensitivity" (17 dB).
