Although widely reported in children, the malarial retinopathy has rarely been described in adults. We observed a case in the department of ophthalmology at the pediatric and gynecology-obstetrics Yaoundé Hospital. The diagnosis revealing a decrease in visual acuity was confirmed by thorough ophthalmological and biological assessments. The basic treatment by quinine therapy was conclusive. The authors point out the need to consider this diagnosis in case of any decrease in visual acuity in febrile context for any adult living or recently having stayed in endemic areas.
