Infectious Uveitis
Toxoplasmosis
 Toxoplasmosis is the most common cause of retinitis in immunocompetent patients. Most cases are acquired postnatally; however, congenital cases occur as well, particularly in countries where infection is endemic. Symptoms of Treatment is recommended for patients with posterior lesions that threaten vital visual structures, such as the optic disk or macula, and for immunocompromised patients. Multidrug therapy is commonly prescribed; it includespyrimethamine, sulfonamides,clindamycin, and, in select cases, systemic corticosteroids. Corticosteroids should not, however, be used without concurrent antimicrobial coverage. Vision-threatening lesions in the macula or adjacent to the optic nerve require intravitrealclindamycininjections. Toxoplasmosis can recur, and patients with vision-threatening lesions may require long-term prophylaxis withtrimethoprim-sulfamethoxazole. Long-acting periocular and intraocular corticosteroids (eg,triamcinoloneacetonide) should be avoided. Patients with small peripheral lesions that do not directly threaten vital visual structures may be observed without treatment and should begin to show slow improvement in 1 to 2 months.
