RESUMO
OBJETIVO: Describir un caso de absceso iridiano en un paciente con leucemia. CASO CLÍNICO: Varón, 46 años, con leucemia promielocítica y endocarditis presentó disminución de agudeza visual en ojo izquierdo (OI). A la exploración oftalmológica: en OI, lesión nodular iridiana a las 4 h con hipopión y exudado fibrinoso y en OD; tyndall +1. Cultivos de sangre y de humor acuoso dieron positivo a Staphylococcus aureus meticilina-sensible, descartando células blásticas en anatomía patológica. Se trató con antibióticos sistémicos con resolución completa de la inflamación. CONCLUSIÓN: El absceso iridiano es un foco inusual de émbolo séptico tras endocarditis bacteriana. En un paciente con leucemia es implescindible descartar metástasis extramedular porque condiciona el pronóstico
PURPOSE: To report a case of iris abscess due to bacterial endocarditis. CASE REPORT: A 46-year-old male under diagnosis of promielocitic leukemia and endocarditis presented with decreased vision in left eye (OS). Ophthalmic exploration revealed iris abscess and hypopyon with fibrinous exudate in iris of the left eye and tyndall +1 in right eye (OD). Blood culture and anterior chamber paracentesis was positive for methicillin-sensitive Staphylococcus aureus and negative for blastic cells in citology. Treatment with systemic antibiotic was initiated with total resolution of inflammation. CONCLUSION: Iris abscess is an unusual septic focus in bacterial endocarditis. It is crucial to rule out an extramedullary metastasis in a patient with leukemia due to the general prognosis
