摘要

因單眼重度弱視或視力喪失所引起之斜視，一般被認為在斜視手術後之眼位穩定度不佳，但在文獻上卻鮮少有相關論文報告。本篇統計了兩組病人之手術結果，研究組共28人，視力在無光覺至20/200之間，術後追踪3至35個月，平均14.6個月；控制組共47人，視力20/25至20/20，術後追踪3至41個月，平均10.7個月。結果在研究組有60.7%，控制組有78.7%，在最後一次檢查結果為10個稜鏡角度以內之偏斜，最後平均眼位則分別為14.3±15.4及7.4±12.3個稜鏡角度，並無統計上之差別意義(P=0.191)。此外，在追踪期間內兩組分別有9.5±10.4及5.8±8.5個稜角度之變化，亦無明顯差異(P=0.142)，此結果顯示，雖然視力不佳者之手術成功率稍低，但仍可有好的外觀及維持穩定眼位之能力。

Sensory heterotropia is defined as a deviation of one eye following severe impairment of visual acuity. It is generally thought that these patients do not maintain the alignment of visual axes after strabismus surgery. A search of the literature has not revealed a great deal of information on this subject. The purpose of this study was to compare the surgical result of the study group (vision range light perception to 20/200) with that of the control group (vision range 20/25 to 20/20). The average follow-up period was 14.6 months (range 3 to 35 months) in study group (28 cases) and 10.7 months (3 to 41 months) in control group (47 cases). There were 60.7% in study group and 78.7% in control group had deviation within ±10 PD at the final visit (p=0.004). The average final deviation was 14.3±15.4 PD in study group and 7.40±12.3 PD in control group respectively (p=0.191). The average change in deviation was 9.5±10.4 PD in study group and 5.8±8.5 PD in control group during follow-up period (p=0.142). These results suggest that although the success rate in study group was not as high as that in control group, poor vision does not preclude good cosmetic outcome and stable alignment postoperatively.
