A literature review on Fuchs uveitis syndrome: An update

Fuchs uveitis syndrome is a chronic, typically unilateral, ocular condition characterized by an asymptomatic mild inflammatory syndrome that can result in cataract and secondary glaucoma. Diagnosis is largely clinical because the etiology remains obscure. Fuchs uveitis syndrome is most likely the result of different insults or pathogenic mechanisms, including infections, autoimmune diseases, hereditary and sympathetic dysfunction. According to the infectious theory, the infection of herpes simplex virus, ocular toxoplasmosis, cytomegalovirus, rubella virus, and other viruses have been implicated in the pathogenesis of the disease. There is no indication for corticosteroid therapy in Fuchs patients, and treatment should be mostly reserved to cataract and glaucoma. Phacoemulsification with intraocular lens implantation is a safe procedure with good visual outcomes in patients with Fuchs uveitis syndrome. Glaucoma is often unresponsive to treatment and should actively be monitored both preoperatively and postoperatively in these patients. We discuss the current understanding of Fuchs uveitis syndrome from its clinical presentations through recommended management and provide a comprehensive description and the updated knowledge of its pathophysiology.
