목적: 열공망막박리에서 25게이지 기구를 이용한 유리체 절제술을 시행하고, 임상성적을 알아보고자 하였다. 대상과 방법: 열공망막박리로 25게이지 경결막 무봉합 유리체 절제술을 시행 받고 3개월 이상 경과관찰이 가능하였던 46명 환자,46안을 대상으로 수술 후 일차 성공률, 최종성공률, 최대 교정시력, 합병증 등을 후향적으로 조사하였다. 결과: 40안은 유수정체안, 6안은 인공수정체안이었고, 26안은 상부망막에 12안은 하부망막, 8안은 상하망막 모두에 열공이 위치하였다. 평균 수술시간은 56.3분이었으며, 일차수술 성공률은 93.48% (43/46)이었다. 재발한 3안 중 2안은 외래에서 액체-가스 교환술,추가 장벽레이저술을 시행하였으며, 1안에서 재수술을 시행하였고, 최종 성공률은 100%이었다. logMAR로 환산한 최대 교정 시력은황반부가 박리된 30안은 수술 전 1.34 ± 0.64 logMAR에서 수술 후 0.48 ± 0.41 logMAR로 향상되었고(p<0.01), 황반부가 유착된16안은 0.32 ± 0.61 logMAR에서 수술 후 0.07 ± 0.13 logMAR로 향상되었다(p=0.279). 합병증은 수술 종료 시 공막절개창 누출2안, 백내장 13안, 유리체 출혈 1안, 저안압 1안, 안압 상승 7안이 있었다. 결론: 열공망막박리에 있어서 25게이지 경결막 무봉합 유리체 절제술은 성공적인 망막 유착 및 수술 후 시력 호전에도 좋은 결과를보인다.
Abstract
Purpose: To evaluate 25-gauge transconjunctival sutureless vitrectomy for primary repair of rhegmatogenous retinal detachment(RRD). Methods: We performed a retrospective study of 46 consecutive eyes of 46 patients who underwent 25-gauge transconjunctivalsutureless vitrectomy to repair primary RRD. Outcome measures included single surgery anatomical success rate, final anatomicalsuccess rate, postoperative visual acuity, and surgical complications. Results: Forty eyes were phakic and six eyes were pseudophakic. Twenty-six eyes had superior quadrant retinal tear, 12 eyeshad inferior quadrant tear and eight eyes had both. The mean operation time was 56.3 minutes. The single surgery anatomicalsuccess rate was 93.48% (43/46). Two eyes with recurrent retinal detachment underwent fluid gas exchange: one received barrierlaser treatment in the outpatient clinic, and the other underwent reoperation; the final success rate was 100%. The best correctedvisual acuity improved from 1.34 log MAR to 0.48 log MAR (p < 0.01) in macula - off patients (30 eyes) and from 0.32 logMAR to 0.07 log MAR (p = 0.279) in macula - on patients (16 eyes). Postoperative complications included wound leaking (twoeyes), cataract progression (13 eyes), vitreous hemorrhage (one eye), transient hypotony (one eye), and increased intraocularpressure (seven eyes). Conclusions: Primary repair of RRD using 25-gauge transconjunctival vitrectomy resulted in an excellent final anatomical successrate and postoperative visual outcomes.
