Abstract

We determined the location for fixation and performed macular microperimetry using a scanning laser ophthalmoscope and examined binocular function with the Bagolini striated glass test, Titmus stereo test and TNO test in 19 patients with idiopathic macular holes that had closed successfully after surgery. The postoperative stereoscopic threshold correlated significantly with preoperative visual acuity, postoperative visual acuity, and retinal sensitivity in the foveal resion (Spearman correlation coefficients by rank were p=0.023, 0.026, and 0.023). No correlation was found, however, between stereoacuity and retinal sensitivity of the fixation point. The stereoscopic threshold in the 7 patients (37%) who had dense foveal scotoma was significantly lower than the threshold in patients without a dense scotoma, and patients with good retinal sensitivity in the foveal region were found to have good stereoscopic thresholds.
