A Choroidal Schwannoma Confirmed by Surgical Excision

Schwannomas rarely present as intraocular tumors and are often misdiagnosed as malignant melanoma. We describe a choroidal schwannoma confirmed by sclerouvectomy. A 30-year-old woman presented with a large nonpigmented intraocular mass of the choroid in the right eye and underwent surgical excision by sclerouvectomy. Histologically, the tumor was composed of a mixture of cellular solid components (Antoni A) and loose myxoid components (Antoni B). The tumor was eventually diagnosed as a schwannoma. Currently available ancillary studies are still of little value in definitively differentiating schwannomas from other choroidal tumors. In the case of atypical findings for a malignant melanoma, a benign neoplasm should be included in the differential diagnosis. This patient avoided enucleation by first having the mass excised. We are unaware of previous reports in which a choroidal schwannoma was diagnosed by surgical excision.

본 연구에서는 승마시뮬레이터 운동과 가상현실운동이 정상인의 균형능력에 미치는 영향을 알아보았 다. 그 결과 가상현실운동보다 승마시뮬레이터 운동이 균형능력 향상에 더 큰 균형능력 증진 효과가 있었다.
