視網膜脈絡膜炎極少見。②全身性感染多見于免疫缺損者(如艾滋病、、惡性腫瘤、主要為何杰金氏病、淋巴瘤等)以及實驗室工作人員等，常有顯著全身癥狀，如高熱、斑丘疹、肌痛、關節痛、頭痛、嘔吐、譫妄，并發生腦炎、心肌炎、肺炎、肝炎、胃腸炎等。眼弓形蟲病多數為先天性、后天所見者可能為先天潛在病灶活性所致。臨床上有視力模糊、盲點、怕光、疼痛、淚溢、中心性視力缺失等，很少有全身癥狀。炎癥消退后視力改善，但常不*恢復。可有玻璃體混濁。獲得性弓形蟲病較先天性弓形蟲病的表現更為復雜。病情的嚴重性與機體的免疫功能是否健全有關。⒈免疫功能正常人的獲得性弓形蟲病大多數病人無癥狀，有癥狀者約%—%，主要臨床表現有發熱，全身不適，夜間出汗，肌疼痛，咽痛，皮疹，肝、脾腫大，全身淋巴結腫大等。淋巴結腫大較為突出，除淺淋巴結腫大外，縱隔、腸系膜、腹膜后等深部淋巴結也可腫大，腹腔內淋巴結腫大時可伴有腹痛。腫大的淋巴結質硬，可伴有壓痛但不化膿。癥狀和體征一般持續—周消失。少數病程可達年。個別病人可出現持續性高熱，單例視網膜脈絡膜炎，一過性肺炎，胸腔積液，肝炎，心包炎，心肌炎，吉蘭—巴雷綜合征，顱內占位病變和腦膜腦炎等。
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.
