The visual acuity of 4 infants with congenital cataracts was measured serially during the first year of life by a preferential looking technique. Two infants with bilateral cataracts and no measurable acuity before surgery showed rapid development of acuity to normal levels for age after surgery and optical correction. In an infant with a unilateral cataract and an infant with a cataract and persistent hyperplastic primary vitreous marked differences in monocular acuities were found after surgery. Acuities became equal in the latter case after occlusion of the normal eye, while the other infant recovered acuity with 'bi-ocular' viewing. These acuity measurements demonstrate the sensitivity of the human visual system to binocular and monouclar visual form deprivation in the first year of life.
采用优先注视技术，对4例先天性白内障婴儿在出生后第一年进行了连续视力测量。2例双侧白内障婴儿术前视力无法测量，术后经光学矫正，视力迅速发展至该年龄的正常水平。1例单侧白内障婴儿和1例伴有永存原始玻璃体增生症的白内障婴儿，术后单眼视力存在显著差异。在后一例中，遮盖正常眼后两眼视力变得相等，而另一名婴儿通过“双眼”注视恢复了视力。这些视力测量结果表明，人类视觉系统在出生后第一年对双眼和单眼视觉形式剥夺很敏感。
