Twenty-nine patients (30 eyes) with pseudo-opercula were followed up for six to 65 months (mean, 24 months). Visual acuity was 20/30 or better in all but one eye that was amblyopic. Only one eye developed a decrease in visual acuity and changes interpreted as a stage 1 (foveal detachment induced by tangential traction of the cortical vitreous) impending hole. After vitrectomy visual acuity returned to 20/20. Ultrasonographic examination confirmed the presence of pseudo-opercula in all 22 eyes examined. We concluded that the a pseudo-operculum is a favorable prognostic sign and that its presence is demonstrable ultrasonographically.
