Development of Foveolitis in a Patient with Active Ocular Toxoplasmosis During a Dengue Epidemic in Misiones Province, Argentina: A Case Report

This report details the development of foveolitis in a patient undergoing antiparasitic treatment and corticosteroid taper for reactivated toxoplasmic retinochoroiditis.OCT findings included ellipsoid zone disruption and scattered hyper-reflective dots within the inner layers of the retina.Foveolitis is a frequent form of presentation of dengue maculopathy.Although the patient resided in Misiones Province, Argentina, amidst a Dengue epidemic, serological tests for IgM and IgG anti-Dengue antibodies were negative.In this manuscript we provide possible explanations on the association of active Ocular Toxoplasmosis and the sudden development of Foveolitis amidst a Dengue epidemic despite negative Dengue serology.
