Following successful surgery 20 cases of retinal detachment with previous separation of the macular area were submitted to examination of visual acuity, colour perception and metamorphopsia. Improvement of visual acuity usually developed during the 12-week-period of supervision; this improvement was related to the preoperative duration of the detachment. The disturbance of colour sense was confined to the perception of yellow and blue, beeing independent of the duration of the retinal detachment; as a rule a tendency to improvement was found during the time of observation. Labile postoperative metamorphopsias were more pronounced in the spoke-test than in the Amsler-test. No evident connexions between the duration of retinal detachment and the intensity of metamorpoptic distortions could be found. In cases with retinal tears in the posterior segment cured with a high plombade effect stable visual distortions occurred in the Amsler-test only. Such distortions seem to be due to mechanical factors and cannot be considered real metamorphopsias.
20例黄斑区先前已分离的视网膜脱离患者在成功手术后接受了视力、色觉和视物变形检查。视力改善通常在12周的观察期内出现；这种改善与术前视网膜脱离的持续时间有关。色觉障碍仅限于对黄色和蓝色的感知，与视网膜脱离的持续时间无关；通常在观察期间发现有改善的趋势。术后不稳定的视物变形在辐辏试验中比在阿姆斯勒试验中更明显。未发现视网膜脱离持续时间与视物变形扭曲强度之间有明显关联。在后部节段有视网膜裂孔且用高填充物效果治愈的病例中，仅在阿姆斯勒试验中出现稳定的视觉扭曲。这种扭曲似乎是由机械因素引起的，不能视为真正的视物变形。
