通过对少数民族学龄前儿童的人群研究，确定视力下降的患病率和原因。基于人口的横断面研究。洛杉矶县44个人口普查区30至72个月的儿童。一个以人群为基础的儿童样本进行了全面的眼科评估，包括单眼VA测试，遮盖测试，睫状肌麻痹自动验光，眼前节和眼底评估，VA重新测试与屈光矫正。确定视力下降的患病率和病因，包括目前和最佳测量的视力，以及较好的眼睛和较差的眼睛。具有可识别眼科病因的就诊和最佳测量VA降低的患病率。对3207名儿童进行了VA评估，并对3364名儿童进行了最佳测量VA。虽然近三分之一的视力下降的病例没有可识别的眼科病因，但这一比例随着年龄的增长而下降。视力下降，复测解决，并与未矫正的屈光不正，存在于4.3%的非洲裔美国儿童和5.3%的西班牙裔儿童，在较好的眼睛1.9%的非洲裔美国儿童和1.7%的西班牙裔儿童。在1.5%的非裔美国儿童和1.9%的西班牙裔儿童的较差眼睛中，以及0.8%的非裔美国儿童和0.6%的西班牙裔儿童的较好眼睛中，观察到最佳测量视力下降，这种视力下降不能用眼镜立即矫正，并且是由于眼部疾病、单侧或双侧弱视或可能的双侧屈光不正性弱视。屈光不正性弱视是最常见的原因。在洛杉矶县，超过5%的非裔美国人和西班牙裔学龄前儿童患有未矫正屈光不正引起的可矫正视力损伤，或与屈光不正相关的弱视引起的视力损伤。
To determine the prevalence and causes of decreased visual acuity (VA) in a population-based study of minority preschool children. Population-based cross-sectional study. Children 30 to 72 months of age in 44 census tracts in Los Angeles County. A population-based sample of children underwent comprehensive ophthalmic evaluation including monocular VA testing, cover testing, cycloplegic autorefraction, anterior segment and fundus evaluation, and VA retesting with refractive correction. The prevalence and etiology of decreased VA were determined, for both presenting and best-measured VA, and better eye and worse eye. Prevalence of decreased presenting and best-measured VA with an identifiable ophthalmic etiology. Presenting VA was assessed in 3207 children and best-measured VA in 3364 children. While nearly a third of cases of worse-eye decreased presenting VA were without an identifiable ophthalmic etiology, this proportion decreased with increasing age. Decreased presenting VA that resolved with retesting and was associated with uncorrected refractive error was present in the worse eye of 4.3% of African-American children and 5.3% of Hispanic children, and in the better eye of 1.9% of African-American children and 1.7% of Hispanic children. Decreased best-measured VA that was not immediately correctable with spectacles and that was due to ocular disease, unilateral or bilateral amblyopia, or probable bilateral ametropic amblyopia, was seen in the worse eye of 1.5% of African-American children and 1.9% of Hispanic children, and in the better eye of 0.8% of African-American and 0.6% of Hispanic children. Amblyopia related to refractive error was the most common cause. Over 5% of African-American and Hispanic preschool children in Los Angeles County have either correctable visual impairment from uncorrected refractive error, or visual impairment from amblyopia related to refractive error.
