The aim of this work is to report two cases of cortical blindness, evaluated at an ophthalmologic service (Clínica de Olhos da Santa Casa de Belo Horizonte). Cortical blindness is a rare, usually ischemic, bilateral retrogeniculate lesion. The two diagnoses were based on patient complaints, ophthalmologic data and image signs. Both patients suddenly lost their visual function. None presented a significant improvement in their final vision acuity during the evolution. Subnormal visual acuity is an important ophthalmologic sign that must be seen with concern and attention since it may be caused by cortical blindness, a rare and serious condition not yet well studied in our Country.
