【摘要】：目的探討20G和23G聯(lián)合玻璃體切割術治療玻璃體視網膜疾病的臨床療效。方法本研究為前瞻性臨床研究,將首次行玻璃體切割術的玻璃體視網膜疾病患者99例99眼納入研究,利用隨機數(shù)字表法將患眼隨機分為傳統(tǒng)20G玻璃體切割組(A組)、經結膜20G玻璃體切割組(B組)、20G和23G聯(lián)合玻璃體切割組(C組),每組各33眼。觀察各組患者行玻璃體切割術的手術時間,術后1 d、3 d、7 d術眼的舒適度,術后1周的矯正視力、眼壓及并發(fā)癥等情況。結果各組手術前后矯正視力比較,差異有統(tǒng)計學意義(均為P=0.000),各組之間手術前后視力差異無統(tǒng)計學意義(均為P0.05)。各組手術時間比較,A、B、C各組的手術時間分別為80~135 min、65~115 min、64~100 min,A組與B、C兩組之間比較,差異有顯著統(tǒng)計學意義(P=0.003、0.002)。B、C兩組之間進行比較,差異無統(tǒng)計學意義(P=0.12)。各組患者術后不同時間點術眼舒適度進行比較,A組與B、C兩組分別比較,差異均有顯著統(tǒng)計學意義(均為P0.01),B、C兩組之間進行比較,差異無統(tǒng)計學意義(均為P0.05)。術后1周內,患者的眼壓為(14.25±3.18)mmHg(1 kPa=7.5 mmHg),術后不同時間點,各組患者無一例發(fā)生低眼壓等并發(fā)癥。術后并發(fā)癥各組之間比較,差異無統(tǒng)計學意義(均為P0.05)。結論 20G和23G聯(lián)合玻璃體切割手術,手術安全高效,操作簡便易行,易于推廣和使用。
[Abstract]:Objective to investigate the clinical effect of 20g and 23G combined with vitrectomy in the treatment of vitreoretinal diseases. Methods 99 cases (99 eyes) of vitreoretinal diseases who underwent vitrectomy for the first time were included in the prospective clinical study. The eyes were randomly divided into traditional 20G vitrectomy group (group A) by random digital table method. There were 33 eyes in each group through conjunctival 20G vitrectomy group (group B) and 20G and 23G combined vitrectomy group (group C). The operation time of vitrectomy, the comfort of eyes 1 day, 3 days and 7 days after operation, the corrected visual acuity, intraocular pressure and complications 1 week after operation were observed. Results there was significant difference in corrected visual acuity before and after operation (all P 鈮，
