Abstract
목적 : 백내장수술 전 구후마취 주사 직후 발생한 망막중심동맥과 중심정맥폐쇄에 대하여 보고하고자 한다. 증례 요약 : 4일 전 좌안의 초음파수정체유화술 및 인공수정체 삽입술을 받은 62세 여자 환자가 전원되었다. 시력은 좌안 안전수지였고 구심성동공장애가 관찰되었으며 안저 검사상 후극부에 불규칙한 형태의 점상 및 원형출혈과 부분적으로 선형의 다양한 망막출혈이 산재되어 있었다. 형광안저촬영상 비측 및 이측의 분지동맥들은 형광이 전혀 충만되지 않았고, 정맥도 충만이 매우 지연되어 있었다. 2주 후 좌안 시력은 안전수동이고, 안압은 좌안 10 mmHg이었다. 안저검사상 후극부 망막출혈은 크기와 양이 좀 더 증가하였고 황반의 창백한 부종은 지속되었다. 형광안저촬영에서 비측 및 이측의 분지동맥과 정맥들은 여전히 형광이 충만되지 않았고, 안저 전체의 모세혈관비관류가 더욱 뚜렷해졌다. 2개월 후 시력은 좌안 안전수동이고, 안압은 좌안 35 mmHg, 신생혈관녹내장이 합병되었다. 결론 : 본 환자를 통해 수술 전 구후마취 시 심각한 망막중심혈관의 폐쇄가 일어날 수 있음을 알 수 있으며 좀 더 안전한 구후마취 주사방법이 연구되어야 할 것으로 사료된다.
PURPOSE To report central retinal vein and artery occlusion after retrobulbar anesthesia for a cataract operation. CASE SUMMARY: A 65-year-old woman was transferred to our facility 4 days after she had undergone cataract extraction with IOL implantation. She could count fingers and had a relative afferent papillary defect in her left eye. As seen upon fundus examination, dot-shaped, circular-shaped irregular, and partially linear-shaped retinal hemorrhages were evident. Fluorescein angiography revealed that branch arteries around the nasal and temporal areas were not filled, and that the filling of veins was delayed. After two weeks, the patient was only able to recognize hand motion, and her intraocular pressure was 10 mmHg. According to a fundus examination, the size and quantity of retinal hemorrhages increased, and a pale, macular edema was observed. Following fluorescein angiography, the filling defect of branch vessels on the nasal and temporal areas was still evident, and the blocked fluorescence of capillaries on the fundus was prominent. After two months, she could still only recognize hand motion, and her intraocular pressure had increased to 35 mmHg; we therefore diagnosed a neovascular glaucoma. CONCLUSIONS: A patient experienced a serious central retinal vessel occlusion after retrobulbar anesthesia for cataract extraction. Retrobulbar injections should therefore be administered with great caution to prevent this outcome.
