RESUMO
BACKGROUND: Sarcoidosis is a multisystemic granulomatous disease of unknown etiology. Ocular manifestations commonly occur in patients with sarcoidosis, with a granulomatous anterior uveitis as the most-prevalent ocular sign. Acute symptoms of uveitis, such as pain, photophobia, lacrimation, or redness, may be absent. Without early detection and timely treatment, this "silent uveitis" may cause permanent ocular damage. CASE REPORTS: Two patients came in for routine eye examinations, with no symptoms of anterior uveitis. The first, a 36-year-old man, had a bilateral granulomatous anterior uveitis. The uveitis was treated with topical corticosteroids, with no complications. The second case involved a 44-year-old woman with chronic, recurrent, bilateral, non-granulomatous anterior uveitis. Despite treatment with topical and oral corticosteroids. the patient had a prolonged course with recurrent episodes leading to secondary sequelae, including glaucoma and cataract. Both patients were co-managed with internal medicine, and in each case, systemic workups were consistent with sarcoidosis. CONCLUSION: Anterior uveitis often manifests as the initial presentation of sarcoidosis. Without acute symptoms, the detection and diagnosis may be delayed, leading to visual deterioration. The diagnosis of sarcoidosis may be difficult, owing to the lack of definitive diagnostic criteria and a variety of presentations. Histologic confirmation may not always be possible or practical. However, a range of serological and radiological tests, when combined with physical and ophthalmic evaluation, can lead to the presumed diagnosis of sarcoidosis. Aggressive treatment is imperative in order to prevent permanent structural damage to the eye resulting from this idiopathic inflammation.
