为探讨眼内肿瘤细胞能否种植于经细针穿刺活检后的巩膜穿刺道内，我们将Y79Rb细胞注入已用透明质酸酶液化玻璃体的32只兔眼内，造成不同眼压状态下Rb细胞眼内播散的动物模型，然后用5号针头自睫状体平部刺入球内，吸取少许玻璃体行细胞学检查，再将眼球摘除对巩膜穿刺道行常规病理检查，结果28个完整穿刺道切片中均未见有Rb细胞种植、嵌顿，巩膜纤维组织断端向外反折，形成自身嵌闭，其中高眼压组这种改变更为明显。实验病理证实细针穿刺活检诊断方法是可行的。
To investigate whether intraocular tumor cells could be implanted in the scleral puncture tract after fine needle aspiration biopsy, we injected Y79Rb cells into 32 rabbit eyes that had been liquefied with hyaluronidase, resulting in different intraocular pressure Disseminated animal models, and then with a # 5 needle ciliary body from the Ministry of flat into the ball, draw a small amount of vitreous cytology, then enucleation of the scleral puncture pathological routine examination, the results of 28 complete puncture slice Rb cells were not seen in planting, incarcerated, scleral fibrillation outward fracture ends, the formation of its own closed, including the intraocular pressure of this change is even more apparent. Experimental pathology confirmed fine needle aspiration biopsy diagnostic method is feasible.
