小児における片眼高度近視と弱視

Unilateral high myopia and amblyopia in childhood

緒　言

　視覚形成前に起こる高度近視，ことに片眼性高度近視は，不同視弱視との関係と病的近視（変性近視）の研究の面から検討を要する眼疾といえる。

　乳幼児期に起こる片眼高度近視には，他の眼疾に随伴する場合がある。例えば，瘢痕性未熟児網膜症，網膜有髄神経線維，牛眼などにみられる近視がそうである。

We studied 17 children with unilateral high myopia with amblyopia using electrophysiological methods, ultrasonography, orthoptic and routine ophthalmological examinations. We also evaluat-ed the response to treatment for amblyopia.

The cases were divided into two groups depend-ing upon their fundus findings. Group 1 included 11 cases showing myopic fundus changes only. Group 2 included 4 cases with cicatricial stage of retinopathy of prematurity and 2 cases with medullated nerve fibers.
