Other Names:
Idiopathic retinal vasculitis-aneurysms-neuroretinitis syndrome; Idiopathic retinal-aneurysms-neuroretinitis syndrome
Categories:
IRVAN syndrome is an acronym for "idiopathic retinal vasculitis-aneurysms-neuroretinitis syndrome," a condition that primarily affects the eyes. Although this condition can occur in people of all ages, it is most commonly diagnosed in the third or fourth decade of life.[1][2] The severity of the condition varies from person to person with some affected people experiencing a mild form that resolves on its own and others experiencing a severe form that may progress to vitreous hemorrhage (leakage of blood into the eye), vision loss and/or glaucoma. The underlying cause of IRVAN syndrome is currently unknown. Most cases occur sporadically in people with no family history of the condition. Treatment varies based on the severity of the condition and the associated signs and symptoms. In severe cases, surgery or medications such as corticosteroids may be recommended.[1]

This table lists symptoms that people with this disease may have. For most diseases, symptoms will vary from person to person. People with the same disease may not have all the symptoms listed. This information comes from a database called the Human Phenotype Ontology (HPO) . The HPO collects information on symptoms that have been described in medical resources. The HPO is updated regularly. Use the HPO ID to access more in-depth information about a symptom.
