| Abstract |
|
It is the purpose of this study to compare the postoperative results of 168 patients with exotropia of basic and simulated divergence excess type over 40 prism diopters; 86 patients had bilateral rectus muscle recessions and 82 patients underwent lateral rectus muscle recession and medial rectus muscle resection. The patients in the former group had averaged 13.7 years of age and 8.2 months of postoperative follow-up period. Those in the latter group averaged 22.9 years and had been followed up for 7.1 months. The postoperative success rates are as follows: 66.7%(57/86) in the bilateral rectus muscle recession group and 68.1%(58/82) in the lateral rectus muscle recession and medial rectus muscle resection group(P>0.05). And the success rates of those older than 16 years without amblyopia are 60.0%(18/30) in the former group and 75.0%(24/32) in the latter group(P>0.05). The lateral rectus muscle recession and medial rectus muscle resection group showed somewhat higher rates of success even though it proved statistically insignificant. |
