视网膜脉络膜炎极少见。②全身性感染多见于免疫缺损者(如艾滋病、、恶性肿瘤、主要为何杰金氏病、淋巴瘤等)以及实验室工作人员等，常有显著全身症状，如高热、斑丘疹、肌痛、关节痛、头痛、呕吐、谵妄，并发生脑炎、心肌炎、肺炎、肝炎、胃肠炎等。眼弓形虫病多数为先天性、后天所见者可能为先天潜在病灶活性所致。临床上有视力模糊、盲点、怕光、疼痛、泪溢、中心性视力缺失等，很少有全身症状。炎症消退后视力改善，但常不*恢复。可有玻璃体混浊。获得性弓形虫病较先天性弓形虫病的表现更为复杂。病情的严重性与机体的免疫功能是否健全有关。⒈免疫功能正常人的获得性弓形虫病大多数病人无症状，有症状者约%—%，主要临床表现有发热，全身不适，夜间出汗，肌疼痛，咽痛，皮疹，肝、脾肿大，全身淋巴结肿大等。淋巴结肿大较为突出，除浅淋巴结肿大外，纵隔、肠系膜、腹膜后等深部淋巴结也可肿大，腹腔内淋巴结肿大时可伴有腹痛。肿大的淋巴结质硬，可伴有压痛但不化脓。症状和体征一般持续—周消失。少数病程可达年。个别病人可出现持续性高热，单例视网膜脉络膜炎，一过性肺炎，胸腔积液，肝炎，心包炎，心肌炎，吉兰—巴雷综合征，颅内占位病变和脑膜脑炎等。
Retina choroiditis is rare. 2 Systemic infection is more common in immunocompromised persons (such as AIDS, malignancy, major reasons for JK, lymphoma, etc.) and laboratory workers, often with significant systemic symptoms such as high fever, rash, myalgia, Joint pain, headache, vomiting, spasms, and encephalitis, myocarditis, pneumonia, hepatitis, gastroenteritis, etc. Toxoplasmosis of the eye is mostly congenital, and what is seen in the day after tomorrow may be due to an innate potential lesion activity. There are clinically blurred vision, blind spots, photophobia, pain, tears, and lack of central vision. There are few systemic symptoms. Visual acuity improves after inflammation subsides, but often does not fully recover. There may be vitreous opacities. Acquired toxoplasmosis is more complicated than congenital toxoplasmosis. The severity of the condition is related to whether the body's immune function is sound. 1. Acquired toxoplasmosis in immunocompetent persons Most patients are asymptomatic, with about %-% of the symptoms. The main clinical manifestations are fever, general malaise, night sweating, muscle pain, sore throat, rash, liver and spleen Large, full-body lymphadenopathy, etc. Lymph nodes are more prominent, in addition to superficial lymph nodes, the mediastinum, mesentery, retroperitoneal deep lymph nodes can also be enlarged, intra-abdominal lymph nodes may be associated with abdominal pain. Swollen lymph nodes are hard and may be tender but not purulent. Symptoms and signs generally persist - weeks disappear. A few diseases can reach years. Individual patients may have persistent high fever, single case of retinal choroiditis, transient pneumonia, pleural effusion, hepatitis, pericarditis, myocarditis, Guillain-Barre syndrome, intracranial lesions and meningoencephalitis.
