■面部处理能力的发展是一个连续的过程,在成年后达到成熟。为了充分实现它,儿童必须有足够的视觉功能。这项研究的目的是评估生活在发展中国家的视力障碍儿童与相同环境下视力正常儿童的面部记忆能力。
■这是一项病例对照研究。患有不同原因的视力障碍儿童和年龄匹配的正常对照者接受了完整的眼部检查和儿童剑桥面部记忆测试(CFMT-C)。图像显示在计算机屏幕上,测试结果表示为正确答案的百分比(%)。将视力受损的儿童分为双眼和单眼缺陷,并将各组与Kruskal-Wallis检验进行比较。
■样本包括40名视力障碍儿童和31名年龄匹配的对照。各组在年龄和性别分布上没有差异。双眼损伤患者(18名受试者)的平均CFMT-C评分较低,与单眼患者(22例斜视性弱视患者)和正常视力儿童(分别为57.7±18.9、76.2±15.6和71.3±12.7,p=0.008)。
■双眼视力障碍儿童面部记忆能力下降。斜视引起的弱视不影响面部记忆。尝试应侧重于预防视力丧失和早期康复,以便这些儿童能够发展足够的面部记忆能力。
UNASSIGNED: The development of face processing abilities is a continuous process reaching maturity in adulthood. To achieve it in plenitude, children must have an adequate visual function. The purpose of this study was to assess how the face memory ability of children with visual impairment living in a developing country compares to those with normal vision in the same setting.
UNASSIGNED: This was a case-control study. Children with visual impairment of different causes and age-matched normal controls underwent a complete eye examination and the Cambridge Face Memory Test for Children (CFMT-C). Images were presented on a computer screen and the test results were expressed as a percentage of right answers (%). Children with impaired vision were assorted into binocular and monocular deficiency and the groups were compared with the Kruskal-Wallis test.
UNASSIGNED: The sample comprised 40 children with visual impairment and 31 age-matched controls. The groups did not differ in age and gender distribution. Patients with binocular impairment (18 subjects) had lower mean CFMT-C scores, as compared to monocular patients (22 patients with strabismic amblyopia) and children with normal vision (57.7 ± 18.9, 76.2 ± 15.6, and 71.3 ± 12.7, respectively, p = 0.008).
UNASSIGNED: Children with binocular visual impairment had diminished face memory ability. Amblyopia due to strabismus did not affect face memory. Attempts should focus on the prevention of visual loss and early rehabilitation so that these children can develop adequate face memory ability.
