脉络膜骨瘤是一种良性骨化肿瘤,多见于年轻的健康女性,但也有男性和儿童患者的报道。75%的病例为单侧,好发于靠近视乳头区域。瘤体基底部大小为2～22mm,隆起度不高,可伴有视网膜下液和新生血管形成。本病需与脉络膜恶性黑色素瘤、脉络膜痣、脉络膜转移癌,脉络膜血管癌等多种病变进行鉴别。超声波扫描和计算机X线断层扫描,可察见脉络膜的钙化斑块,有助于本病的诊断。荧光血管造影可显示出新生血管组织,为激光光凝提供依据。本病的发病机理尚不清楚,也还没有明确的治疗方法。患者的视力预后差异较大,但全身预后较好。
Choroidal osteoma is a benign ossified tumor, more common in young healthy women, but there are also reports of male and child patients. 75% of cases are unilateral, occur in the area near the optic disc. Tumor base size of 2 ~ 22mm, elevation is not high, may be associated with subretinal fluid and neovascularization. The disease with choroidal malignant melanoma, choroidal nevus, choroidal metastasis, choroidal vascular cancer and other lesions were identified. Ultrasound scan and computerized tomography, the choroidal calcification can be found in the plaque, contribute to the diagnosis of the disease. Fluorescent angiography can show neovascularization and provide basis for laser photocoagulation. The pathogenesis of this disease is not yet clear, there is no clear treatment. Patients with different visual outcomes, but the overall good prognosis.
