Among 251 eyes successfully operated on for retinal detachment, the postoperative visual acuity was better in those without preoperative macular detachment (72 eyes) than in those with macular detachment (179 eyes). In eyes with macular detachment, the level of visual acuity obtained postoperatively was not statistically correlated with the duration of detachment for up to eight weeks. After eight weeks, the prognosis for recovery of macular function was reduced significantly according to the duration of detachment.
