[An investigation of 4,125 cases of Kazak childhood strabismus and amblyopia].
An investigation was made on 4,125 Kazak pupils (aged from 4 to 14 years) with strabismus and amblyopia in 9 schools of 5 countries. Among the subjects examined, 48 cases (1.1%) were strabismus including 32 (66.67%) external and 16 (33.33%) internal strabismus; 15 cases (31.25%) suffered from both strabismus and amblyopia and 33 (68.75%) were strabismus but had normal visual acuity; 139 cases (209 eyes) were amblyopia (morbidity rate: 3.37%) including 70 binocular and 69 monocular amblyopia, 73 males and 66 females. Out of the 209 amblyopia eyes, 84 (40.19%) were slight, 104 (49.76%) medium and 21 (10.05%) serious. Ametropia was also found to be in the majority in Kazak childhood amblyope. Only 106 of 209 eyes were simple farsighted. To prevent the occurrence of amblyopia the writer suggests that efforts of finding and correcting ametropia at early stage should be made.
