Choroidal Involvement in a Case of Viral Retinitis.

PURPOSE: To describe a challenging case of acute retinal necrosis. METHODS: Clinical data, including medical history, clinical findings and imaging features were retrospectively collected in a 28-year-old female with unilateral active retinitis. RESULTS: The yellowish area of retinitis surrounding a pigmented chorioretinal scar and the full thickness retinal hyper-reflectivity associated with diffuse increase in choroidal demonstrated a challenging case of necrotising retinitis, where baseline clinical and tomographic features were atypical and misleading towards a toxoplasmic aetiology. The detection of virus genome in ocular samples was necessary to achieve a correct diagnosis of acute retinal necrosis. CONCLUSION: Although rare, choroidal involvement may occur in acute retinal necrosis along with the well-known retinal features.
