目的：研究近五年来眼肿瘤的临床病理类型，为临床提供诊断和治疗依据。方法：对华西医院眼病理室2003年1月-2008年1月间所检查的619例眼部肿瘤资料进行回顾性分析。结果：良性肿瘤374例，恶性肿瘤245例。按取材的解剖部位分：眼睑肿瘤218例，眼表肿瘤134例，眼球内肿瘤69例，眼眶肿瘤198例。结论：对眼肿瘤进行临床和病理分析有利于临床诊断和处理。
Purpose To investigate nucleoside diphosphate kinase (NDPK ) expression of tumor metastasis suppressor gene nm23 in heterotransplanted model of retinoblastoma(RB) in nude mice，and analyse the correlation between the expression of nm23 gene and the formation and progression of heterotran splanted RB． Methods SP immunohistochemical method was used to detect the expression of nm23 gene product NDPK in 20 tumors of heter otransplanted RB model and normal retinal tissue． Results The negative staining of nm23/ NDPK was found in normal retinal tissue , whereas 100% expression rate in RB tumors with positive number of 48.73plusmn;2.37． No statistical significance of the expression of nm23/ NDPK was observed between the intraocular growth phase （I～Ⅲ grade） and invasive phase （ Ⅳ～Ⅴ grade）in heterotransplantedRB tumors． Conclusion The function of nm23 gene as a tumor metastasis suppressor in heterotra nsplanted RB tumors was less prominent ,but it may play a role in carcinogen esis and progrssion of RB and may predict poor prognosis． (Chin J Ocul Fundus Dis, 2001.17:47-49)
Objective To observe the clinical and pathological characteristics of choroidal metastatic carcinoma from lung carcinoma.Methods The clinical and pathological data of 6 patients with choroidal metastatic carcinoma from lung carcinima were analysed retrospectively.Results All the 6 patients had severe visual impairment, including 3 with severe ophthalmalgia. Flat neoplasm were seen in the posterior pole of the eyes in all the 6 patients and retinal detachment were found in 5 patients. Fundus fluorescein angiography (FFA) examination had been performed on 1 patient and blocked fluorescence and hyperfluorescence were seen in the lesion with pinpoint fluorescein leakage loop around it. CT examination had been performed on 3 patients and the shadow of flat homogenous tumor was seen. MRI examination had been performed on 1 patient and high signal intensit ies on T1W and low signal intensities on T2W were found. In all the 6 patients with primary lung carcinoma, 5 were diagnosed with adenocarcinoma and 1 with cellule carcinoma through pathological examination, and 5 patients were diagnosed with choroidal metastatic carcinoma from adenocarcinoma and 1 with choroidal metastatic carcinoma from cellule carcinoma through pathological examination.Conclusion Rapid visual acuity decrease, severe ophthalmalgia, flat neoplasm in ocular fundus and secondary retinal detachment are the main clinical characteristics of the choroidal metastatic carcinoma from lung carcinoma. Most histopathologica l manifestations of the metastatic carcinoma like that of the primary focus, and adenocarninoma is the most common histoclassification. (Chin J Ocul Fundus Dis，2003，19：333-404)
