[Visual acuity and color sensitivity in retinal detachment]

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.
