Two cases of cyclic esotropia associated with accommodative esotropia

　調節性内斜視に合併した周期性内斜視の2症例について報告した。これらの症例は調節性内斜視の眼鏡装用後の経過観察において，斜視角の増加がみられ，部分的調節性内斜視の状態となり手術の目的で入院させ，術前の検査中に周期性を発見し，手術により周期性は消失し定型的調節性内斜視の状態に復帰した。

Two cases of accommodative esotropia which later became cyclic esotropia are described. The first case, a 5-year-old girl, had developed esotropia at agc 3 which was completely corrected with glas-ses for 8 months. A residual csodeviation gradually increased even with full correction of hypermetro-pia. The second case, a 6-year-old girl, was diag-nosed as esotropia at the age of 2 years and 9 months which was satisfactorily corrected with glasses for the initial 12 months. A residual esotropia started to build up reaching 40 prism diopters.
