摘　　要：Introduction: Ischemic retinal vasculitis is an inflammatory disease affecting the retinal vessels. Visual acuity decreases due to macular ischemia, macular edema, neovascularization leading to vitreous hemorrhage, fibrovascular proliferation or tractional retinal detachment. Purpose: To present the case of a patient with ischemic retinal vasculitis. Material and Methods: The case involves a 34-year-old woman. The following tests were performed: complete blood count, biochemistry, coagulogram, rheumatological tests, serum calcium level, angiotensin-converting enzyme, CT of the lungs, MRI of the brain and spine, serological tests for: cytomegalovirus, herpes simplex virus (type 1 and 2), varicella-zoster virus, toxoplasmosis, tuberculosis, syphilis, as well as fluorescein angiography and optical coherence tomography. Results and Discussion: The patient was admitted to the hospital with visual acuity of the right eye, 0.8/0.9, and of the left eye, 1.0. The intraocular pressure in both eyes was normal: 14 mmHg in the right eye and 15 mmHg in the left eye. The following pathological finding was detected in the right eye fundus: an old chorioretinal cicatrix under the inferior temporal vascular arch with an ischemic exudate next to it, occlusion of the inferior temporal retinal arterial and venous branches, neovascularization and a preretinal hemorrhage. Fluorescein angiography showed delayed filling of the affected vessels, neovascularization, and major ischemia in the lower temporal part of the retina. The results of the serological tests for varicella zoster virus, herpes simplex virus type 1 and toxoplasmosis were outside the reference ranges. The patient was treated with Clindamycin and Acyclovir. Emergency laser therapy was performed in the ischemic retina area. Previous toxoplasma chorioretinitis was diagnosed, which had led to ischemic retinal vasculitis with sectoral involvement of the retinal vessels. The patient has been monitored over 3 - 4 month periods, showing high visual acuity and stable ocular conditIntroduction: Ischemic retinal vasculitis is an inflammatory disease affecting the retinal vessels.
