[Orbital cellulitis and permanent amaurosis: clinical case]. / Celulitis orbitaria y amaurosis permanente: caso clínico.

It is more frequent and benign in children, but in adults usually requieres surgical drainage of the affected sinus. We report a case of aggressive evolution with permanent blindness in an adult without general or local risk factors, in spite of adequate treatment. The literature is reviewed.
