In patients with unilateral detachment of the retina after successful operation (buckling 3x, cerclage 3x, combined operation 4x), the visual acuity was assessed on Snellen optotypes or Landolt's ring chart. Optotype charts with rings were made according to recommendations of the commission for vision of the American Academy of Sciences. Snellen's visual acuity of healthy and affected eyes was 6/9-6/6. In all patients moreover sensitivity to contrast was examined assessed by means of a VISTESCH testing table. It was revealed that sensitivity for contrast in all operated eyes is significantly lower than in healthy eyes and that the threshold visual acuity and steepness of lines is significantly lower.
在视网膜单侧脱离手术成功的患者中（巩膜扣带术3例、环扎术3例、联合手术4例），通过斯内伦视力表或兰多尔特环视力表评估视力。带环的视力表是根据美国科学院视觉委员会的建议制作的。健眼和患眼的斯内伦视力均为6/9 - 6/6。此外，所有患者均使用VISTESCH测试表检查对比敏感度。结果显示，所有手术眼的对比敏感度均显著低于健眼，且阈值视力和线条陡度也显著降低。
