弓形虫并是由专性细胞内鼠弓形体所起,它是引起后部葡萄膜炎最常见的原因。其发生无种族和性别差异,其典型改变为,在陈旧性视网膜脉络膜瘢痕附近出现局灶性坏死性视网膜脉络膜炎。临床上根据其典型的病灶特征可以作出诊断,但对高度疑是弓形虫感染者,作血清抗原抗体的检查,对明确诊断是很有帮助的。我们用ELISA对临床上已诊断为葡萄膜炎患者进了弓形虫循环抗原、特异性抗体的检测。旨在确定可能的病因。 材料和方法 Toxoplasma gondii is caused by obligate intracellular Toxoplasma gondii, which is the most common cause of posterior uveitis. It occurs without ethnic and gender differences, the typical change is the presence of focal necrotizing retinochoroidal retinopathy in the vicinity of chronic retinal choroidal scarring. Clinically based on the characteristics of its typical lesions can make a diagnosis, but highly suspected Toxoplasma gondii infection, serum antigens antibody examination, a clear diagnosis is helpful. We used ELISA to detect Toxoplasma gondii antigens and specific antibodies in patients with clinically diagnosed uveitis. To determine the possible causes. Materials and Method
