本组脉络膜黑瘤6例6眼,均为男性,单眼。(1)临床表现:视力≤0.1者5例,>0.2者1例。眼底检查肿瘤呈青灰色者4例,棕灰色2例。肿瘤周围均有实性视网膜脱离,表面有大片状出血者1例,斑点状出血者5例。肿瘤表面视网膜均有毛细血管扩张。大块状色素沉着者2例,斑点状色素沉着者4例。(2)荧光造影特点:①肿瘤早期无荧光,随后出现斑驳状荧光。②肿瘤表面毛细血管扩张,有广泛荧光素渗漏。③瘤体内出现不规则血管形态。④肿瘤周边部有荧光亮点。⑤肿瘤表面出现散在微血管瘤。(3)病理检查:6例中3例均为混合
6 cases of choroidal melanoma in 6 cases, both men, monocular. (1) clinical manifestations: visual acuity ≤ 0.1 in 5 cases,> 0.2 in 1 case. Fundus examination of the tumor was blue-gray in 4 cases, brown-gray in 2 cases. Solid tumors around the real retinal detachment, the surface of a large flare in 1 case, spot bleeding in 5 cases. Tumor surface retinal capillaries are dilated. 2 cases of massive pigmentation, spot-shaped pigmentation in 4 cases. (2) fluorescence contrast features: ① early tumor no fluorescence, followed by mottled fluorescence. ② tumor surface telangiectasia, there are a wide range of fluorescein leakage. ③ tumor irregular blood vessels within the form. ④ tumor peripheral fluorescence highlights. ⑤ tumor surface scattered micro-hemangioma. (3) pathological examination: 6 cases in 3 cases were mixed
