Abstract

Visual acuity was determined for both eyes of long-term monocular-deprived cats over a wide luminance range. The influence of luminance on the rate of pattern vision recovery was also examined. Unlike strabismic humans and cats, the acuity deficit of monocularly deprived cats is not luminance dependent. This acuity is much worse at all luminance levels in the deprived eye. Likewise, initial testing of the deprived eye at low luminance levels does not facilitate recovery of pattern vision. Therefore, monocular lid fusion results in a visual deficit that differs from the effects of strabismus but resembles the effects of anisometropia in man.

摘要

在很宽的亮度范围内测定了长期单眼剥夺猫双眼的视力。还研究了亮度对模式视觉恢复速率的影响。与斜视的人类和猫不同,单眼剥夺猫的视力缺陷不依赖于亮度。在所有亮度水平下,剥夺眼的视力都差得多。同样,在低亮度水平下对剥夺眼进行的初始测试并不能促进模式视觉的恢复。因此,单眼睑融合导致的视觉缺陷不同于斜视的影响,但类似于人类屈光参差的影响。
