Kyrieleis plaques are described in literature as calcific-appearing segmented inflammatory deposits along retinal arterial branches. (1) This clinical finding is most commonly unilateral and typically adjacent to an area of active retinal infection or inflammation. (2) The plaques do not appear to be intraluminal or extravasal, but rather within the vessel walls. (3) Considered to be a dishonourable eponym, this rare clinical entity is often also documented as segmental retinal periarteritis. Kyrieleis plaques are a diagnosis of exclusion and should be differentiated from other presentations of retinal vessel damage including emboli, artery sheathing, sclerosis, and periphlebitis all of which may warrant prompt referral or comanagement.

The aim of this study was to describe a case of a patient with ocular toxoplasmosis, which has resulted in Kyrieleis plaques formation (segmental periarteritis associated with severe inflammation) and later follow-up and alternative treatment due to documented allergy to sulfonamide. A 33-year-old Brazilian woman diagnosed with acute toxoplasmosis, initially treated with sulfonamide, developed a critical cutaneous rash. Cotrimoxazole was changed to clindamycin and pyrimethamine, and prednisone was started.

Retinal vasculitis is common in ocular toxoplasmosis (OT) and typically occurs in the same quadrant as retinochoroiditis. This is a case of atypical ocular toxoplasmosis with remote vasculitis distant from the retinochoroiditis lesion. Examination of the left fundus showed the classic posterior segment finding of "headlight in the fog" in the absence of a chorioretinal scar.
