目的对高度怀疑Ｃｏａｔ’ｓ病而从临床上不能排除眼内占位性病变的小儿病人进行临床细胞学诊断。方法在实验研究的基础上应用了细针穿刺细胞学检查方法。结果３／１０病例因排除眼内占位性病变明确诊断为Ｃｏａｔ’ｓ病而得以保存眼球。结论细针穿刺细胞学检查方法对明确诊断Ｃｏａｔ’ｓ病、鉴别诊断视网膜母细胞瘤（ＲＢ）有重要临床意义。
OBJECTIVE: To perform clinical cytologic diagnosis of pediatric patients who are highly suspected of Coat’s disease and can not rule out intraocular space-occupying lesions. Methods Based on the experimental study, fine needle aspiration cytology was applied. Results 3 of 10 cases were preserved due to the exclusion of ocular mass lesions diagnosed as Coat’s disease. Conclusions Fine needle aspiration cytology has important clinical significance for the differential diagnosis of Coat’s disease and differential diagnosis of retinoblastoma (RB).
