Synoptophoreによる不等像視検査 第2報片眼無水晶体症について

Studies on aniseikonia using synoptophore slide. II. Unilateral aphakia

　片眼無水晶体症106例について，眼鏡矯正時，コンタクトレンズ矯正時IOL移植眼の各々の不等像視をsynoptophore slideを用いて測定した．

　その結果，眼鏡矯正時は13例中10例が24％以上の不等像視を示した．

　CL矯正時は平均＋4.57％，IOL移植眼では平均＋1.25％の不等像視を示した．不等像視の大小と視力の良否がstereo acuity，特にrandom dotstereogramの成績に影響すると思われた．

We evaluated the state of aniseikonia in 106 cases with unilateral aphakia by means of synoptophore slides. The aphakia was either corrected with ordi-nary glasses, contact lens, or posterior chamber lens implantation.

When corrected with ordinary glasses, the anisei-konia amounted to 24% and over. The aniseikonia averaged +4.75% when corrected with contact lens and +1.25% when corrected with posterior chamber lens.

The amount of aniseikonia and the visual acuity were major determining factors for stereoscopic visual acuity, particularly when tested by random dot stereogram.
