3D Visual Function Trainer-ORTe®を用いた弱視訓練

Training of anisometropic amblyopia using 3D Visual Function Trainer-ORTe®

要約　目的：3D Visual Function Trainer-ORTe^®（ORTe）を用いた弱視訓練の成績の報告。

対象と方法：不同視による弱視者11例を対象とした。男児5例，女児6例で，年齢は4〜9歳，平均6.2歳であった。訓練開始時の弱視眼の視力は全例が0.4以下で，屈折は＋2.5〜＋8.0D，平均＋6.07Dであった。全例に完全屈折矯正眼鏡を装用させ，月1回のORTeによる訓練を1.7±1.3年間行った。

結果：訓練により，全例で1.0の視力が得られた。うち3例では屈折矯正とORTeによる訓練が行われ，8例ではこれに加えて訓練時に3時間の健眼遮蔽が行われた。

結論：不等視弱視の小児に対する完全屈折とORTeによる弱視訓練により，1.0の視力が得られた。

Abstract　Purpose: To report the outcome of training of anisometropic amblyopia using 3D Visual Function Trainer ORTe^®（ORTe）.

Cases and Method: The present study was made on 11 children with anisometropic amblyopia. The series comprised 5 boys and 6 girls. The age ranged from 4 to 9 years, average 6.2 years. All had unilateral amblyopia below 0.4 before start of treatment. The affected eye had refraction from ＋2.5D to ＋8.0D, average ＋6.07D. All cases were instructed to wear fully corrected eyeglasses and to attend a monthly session of training using ORTe.

Results: All cases attained visual acuity of 1.0 in the affected eye after training for an average of 1.7±1.3 year. Three cases received correction of refraction with training by ORTe. The other 8 cases received, in addition, occlusion of affected eye during ORTe training.

Conclusion: Visual acuity of 1.0 was obtained in 11 children with anisometropic amblyopia following full correction and monthly training using ORTe.
