Sarcoidosis diagnosis based on ocular involvement. Case report

Sarcoidosis is a multisystemic disease of unknown cause, secondary to a genetically determined immune reaction triggered by environmental factors, which leads to the formation of non-caseating granulomas. Ocular involvement is the second most frequent after pulmonary involvement. The most common finding is anterior granulomatous uveitis, but posterior uveitis, retinal peri-phlebitis, chorioretinitis, conjunctivitis, scleritis and optic neuritis can also be seen. We describe the case of a pediatric patient with long-standing multisystem involvement disease, in whom the demonstration of non-caseating granulomas in the conjunctival biopsy allowed a presumptive diagnosis of sarcoidosis.
