中文摘要 | 本篇以32位續發性外斜視的病例與165位術後一年以上(平均3.62年)仍維 持正位的穩定病例做分析比較,以探討續發性外斜視發生的相關成因。結果顯 示,調視性內斜視病人如果只矯正非調視部分,且予以較細心的術後追蹤治療, 其發展成續發性外斜視的機會較小。良好的兩眼同視機能及立體感,也是維持眼 位穩定的重要因素。長期的追蹤檢查,本篇發生續發性外斜視的比率在半年時為 6.0,平均3.62年的追蹤檢查為14.8,顯示開刀後雖成±10P.D的正位,但隨追蹤的 時間愈長,續發性外斜視的發生率會逐漸增加。因此許多與年齡變化有關的因 素,如輻輳力、調視力、遠視等,在本篇雖無統計學上的意義,但仍需加以考慮。 術後淨偏移眼位,在穩定組的平均偏位為輕度矯正不足1.67P.D,續發性外斜視組 平均偏位為矯正過度1.69P.D,有統計學上的意義,因此我們建議內斜視的開刀, 以做成輕度矯正不足為原則,日後可獲得最佳的最終眼位。 |
英文摘要 | To find out the possible mechanisms that con-stribute the ocu-rence of consecutive exotropia, several factors were compared and analyzed between the two groups: 32 cases of consecutive exotropia and 165 stable cases on an average follow-up periodof 3.62 years. All of these 197 patients were or the-tropic or within - 10. P.D. one week postoperatively and were followed up for more than one year. Cases of accommodative esotropia were noted to be more stable than those of basic type chiefly be-cause only non-accommodative component was corrected and more meticulous attentions were paid in these patients. Good binocular function might be a very im-portant factor in maintaining the stability of align-ment since none of the consecutive cases had refinedstereopsis( P> 0.01). The incidence of consecutive exotropia in our study varies from 6.0 in 6 months follow-up period to 14.8 at final visit (average 3.62 years). The tendency of exotropic progression was conspicuous even though postoperative or hthotropic alignment was acquired. It is evident that the longer we follow, the more consecutive exotropia we may have. So, we thought that factors related to aging change such as accommodation, convergence, and hyperopia need to be taken into consideration in planning the operation of esotropia even though no significantly statistical difference were revealed in this paper. The average initial postoperative alignment in stable group was slightly under correction 1.67 P.D. while the consecutive group was over correction 1.69 P.D. ( P < 0.005). We suggest that the preferred initial postoperative alignment on esotropia operation is slight under correction that will be expected to have the best long-term results. |
