摘要
本文应用静态立体视仪对111名弱视儿童进行立体视阈值的测定。年龄4至13岁.4~5岁组38人,6~7岁组43人;8~13岁组30人.单眼弱视56人;双眼弱视55人。测定立体视阈值的平均值为;4~5岁组149.64秒角;6~7岁组66.69秒角。8~13岁组48.48秒角;单眼弱视65.32秒角,其中轻度弱视38.6秒角,中度以下弱视88.84秒角.双眼弱视115.81秒角,其中轻度弱视44.09秒角;中度以下弱视175.44秒角.本文还对不同弱视年龄组的立体视分布,弱视程度对立体视阈值的影响,单眼弱视及双眼弱视的立体视比较作了初步分析。
The threshold of stereopsis was measured by static stereopter for 111 children with amblyopia aged from 4 to 13 years. They were divided into three groups; 38 cases ranging in age from 4 to 5 years, 43 cases 6 to 7 and 30 cases 8 to 13. Fifty six cases were unilateral and 55 bilateral amblyopia. The average threshold of stereopsis was 149. 64 second angle for the 4-5 group, 66. 69 for the 6-7 and 48. 48 for the 8-13. The average threshold for unilateral amblyopia was 65. 3, in which mild type was 38. 6 and under moderate type was 88. 84, whereas the average threshold for bilateral cases was 115. 81, in which mild type was 44. 09 and under moderate type was 175. 44. The distribution of stereopsis for different age groups, the threshold of stereopsis influenced by different types of amblyopia and the comparison of amblyopia between bilateral and unilateral are also discussed.
