Threshold visual acuity for three cats which were reared from birth to 4--12 months of age with bilateral lid closure was measured and compared to visual acuity in three cats which had the use of a non-deprived eye. The results indicate that binocular deprivation (BD) results in significant deficits in visual acuity which are proportional to the duration of deprivation. Threshold visual acuities were 3.7 cycles/deg. following 4 months of BD, 3.25 cycles/deg. following 7 months of BD and 2.55 cycles/deg. following 12 months of BD compared to acuities of 6.0, 6.5 and 6.8 cycles/deg9 for cats using a non-deprived eye. All BD cats had recovered from the initial visuomotor deficits, seen in these cats and reported in the literature, following lid-parting. The implication of such deficits in visual acuity on visual discrimination learning in BD cats is discussed.
测量了三只从出生到4至12个月大时双眼睑闭合饲养的猫的阈值视力，并与三只使用未受剥夺眼睛的猫的视力进行了比较。结果表明，双眼剥夺（BD）会导致视力显著下降，且下降程度与剥夺持续时间成正比。与使用未受剥夺眼睛的猫的视力分别为6.0、6.5和6.8周期/度相比，BD 4个月后的阈值视力为3.7周期/度，BD 7个月后的阈值视力为3.25周期/度，BD 12个月后的阈值视力为2.55周期/度。所有BD猫在眼睑张开后，都从这些猫以及文献中报道的最初视觉运动缺陷中恢复过来。讨论了这种视力缺陷对BD猫视觉辨别学习的影响。
