中文摘要 | 背景:探討水晶體脫位之原因與玻璃體併水晶體切除術,術後視力結果的相關性。 方法:從1995至2003年當中,排除水晶體脫位合併視網膜剝離及追蹤時間少於6個月者,共有36個病人36個眼精執行因水晶體脫位說作的玻璃體切除術。患者之臨床表現如文中所術。水晶體脫位之原因與術後之視力結果的相關性的探討是利用費氏統計法。 結果:造成水晶體脫位的原因包括創傷,及眼球內手術。在創傷組及眼球內術後組的玻璃體外除術術後之視力超過20/40者分別佔45%及31%,視力改善者分別佔90%及81%。兩組對於術後視力的好壞並無統計上的意義。39%的病例有明顯影響術後視力之併發症。術後明顯影響視力的因子包括視網膜剝離,黃斑部水腫,及青光眼。 結論:水晶體脫位的原因與其術後之視力並無明顯相關性,因此水晶體脫位的原因並不能成為預做術後視力的重要因子。然而術後之後極部併發症因為會造成術後較差之視力,故可作為評估術後視力之考量。 |
英文摘要 | Backgorund: The aim of this study is to determine the relationship between the cause of lens dislocation and visual outcomes with complications in patients undergoing trans pars plana vitrectomy (TPPV) and trans pars plana lensectomy (TPPL) for lens dislocation. Methods: This retrospective study was carried out from July 1995 through November 2003. after excluding patients with previous retinal detachment or combing lens dislocation and post-TPPV/TPPL follow-up intervals of less than 6 months, 36 eyes from 36 patients who had undergone vitrectomy and lensectomy for lens subluxation or dislocation due to trauma or intraocular surgery were examined. Their presenting features and complications were recorded. The relationship between the cause of lens dislocation and visual outcome with complications was tested using Fisher’s exact test. Results: The cause of lens dislocation included blunt and penetrating eye trauma, and intraocular surgery. Final best-corrected visual acuity was 20/40 or better in 45% of eyes in the traumatic arm and in 31% of eyes in the iatrogenic arm. Visual acuity improved after TPPV/TPPL in 90% of the eyes in the traumatic arm and in 81% of the eyes in the iatrogenic arm. Of all of the eyes, 39% had significant complications affecting postoperative visual outcomes, including retinal detachment, cystoid macular edema, vitreous hemorrhage and glaucoma. Conclusions: There were no significant differences in visual outcomes and complications between the traumatic and iatrogenic arms of the study. Therefore, the cause of lens dislocation was not a predicator of visual outcomes. Nonetheless, posterior segment complications including retinal detachment and glaucoma were major causes of poor postoperative visual outcomes. |
