[Cause of unusual unilateral vitreous hemorrhage: neuroretinitis of Cat-Scratch disease. Presentation of a case].
A 49 years old woman presents an unilateral decrease of vision. An important vitreous hemorrhage obscures the fundus. After partial resorption a typical aspect of neuroretinitis is seen: macular and disc edema with macular star formation. Cat-Scratch disease is suspected after general examination of the patient. This diagnosis will be confirmed by the laboratory investigation. This disease is not so rare and represents one of the principal causes of neuroretinitis. The vitreous hemorrhage can be due to vascular insult by the bacterium responsible for Cat-Scratch disease which one has an important tropism for endothelial cells and can be responsible for vascular occlusive phenomena. Clinical signs, treatment and evolution of this disease are going to be discussed in this article.
