[Ocular infections in immunodepressed patients].

Two kinds of immunosuppression must be distinguished: malignant diseases on one hand, and acquired immunodeficiency syndrome on the other hand. Ocular infections can involve any part of the eye and they can lead to blindness. They usually attest of a systemic infection. Their treatment consist of an induction course to provide complete healing of the lesions, immediately followed by a maintenance course to prevent relapses. Retinitis are the most common posterior involvement, especially the retinitis due to cytomegalovirus and Toxoplasma gondii. Zoster ophtalmicus is the most common anterior involvement. Mucormycosis is rare but very severe. A closed collaboration between ophtalmologists and internists is mandatory to provide the most appropriate management of these infections.
