목적: 유리체 낭포로 진단받은 59세 여자 환자의 증례를 보고하는 바이다.
증례요약: 59세 여자 환자가 내원 약 3개월 전부터 지속된 좌안의 부유물을 주소로 본원에 내원하였다. 이전 외상의 병력이나 감염, 또는 염증의 과거력이 없었으며 선천적 질환 또는 출생 시 합병증 과거력은 없었다. 내원 당시 나안 시력 좌안 1.0 측정되었다. 안저검사상 시신경 유두의 하이측 방면의 유리체 후부에 직경 3-4 DD의 갈색 색소가 침착된 유리체 낭포가 관찰되었다. 안초음파(B-scan)상 echo-free 낭포가 발견되었으며 vitreous strands나 유착은 발견되지 않았다. 형광 안저 혈관 조영술(FluoresceinAngiography)상 유출 소견은 관찰되지 않았다. 처음 내원 후 1개월, 3개월, 6개월 경과관찰 시마다 크기를 비교하였으며 크기 증가나 시력 저하 소견은 발견되지 않아 특별한 치료는 하지 않았다.
결론: 특별한 과거력 및 시력 저하를 동반하지 않은 유리체 낭포의 1예로서 특별한 치료가 요구되지 않았으며 질병은 단기적 경과관찰시 악화되거나 진행하는 양상을 보이지 않았다.Purpose: To report a case of a 59-year-old female with a free-floating monolateral vitreous cyst localized in the posterior vitreous in the left eye.
Case summary: A 59-year-old female who complained of an intermittent floater in the left eye for 3 months visited our clinic. She had been suffering from visual disturbance for approximately 3 months. There was no previous history of trauma, infection, or inflammatory disorders. The best corrected visual acuity was 20/20 in both eyes. On fundoscopic exam, a 3-4 disc diameter (DD) sized, brown-colored pigmented vitreous cyst was detected at the inferior temporal side of the posterior vitreous in her left eye. B-scan ultrasound confirmed the presence of an echo-free cystic formation that was free from surrounding vitreous strands or other adhesions located at the posterior vitreous. No specific findings or leakage were observed on fluorescein angiography. We followed-up the patient periodically (1 month, 3 months, and 6 months after the initial visit) and monitored whether the size or location of the cyst had changed. At every follow-up exam, the size or location of the cyst was stationary and the patient's visual acuity was 20/20 in the affected eye, thus we suggested she should be followed-up periodically for her cyst without any intervention.
Conclusions: We report a case of a patient with no previous ocular history or impaired vision who had a free-floating vitreous cyst localized in the posterior vitreous in the left eye. The disease did not appear to progress or become aggravated over a short-term follow-up period and no specific treatment was required.
