Resum:	Objective: To describe ocular findings associated with Rhodococcus equi bronchopneumonia in foals, and to determine whether severity of the ocular lesions is related with outcome. Animals studied: Foals diagnosed with R equi infection at the VTH-UAB from January 2002 to December 2017. Procedure: Rhodococcus equi infection was diagnosed by means of clinical signs, radiographic/ultrasonographic findings, and/or positive culture. In all the foals, a complete ophthalmic examination by a boarded ophthalmologist was performed and ocular signs were recorded and graded (0-4). Results: Thirty-nine foals were included in the study, from which 12 showed signs of bilateral anterior uveitis (30. 8%). Among these, three foals were classified as mildly uveitis-affected (MUA:7. 7%) and nine as severely uveitis-affected (SUA:23. 1%). Five SUA foals showed green aqueous flare (5/9;55. 5%). Despite the systemic treatment, 9/39 sick foals died (23. 1%), the fatality rate being different between groups: SUA (4/9;44. 4%), MUA (0/3; 0%) and nonuveitis-affected foals (5/27;18. 5%). Among SUA foals, only one with green aqueous flare died (1/5;20%). Conclusion: Bilateral anterior uveitis is highly prevalent in foals with R equi pneumonia (30. 8%). The severity of anterior uveitis might be considered a nonsurvival prognostic factor and, until proven otherwise, green aqueous flare could be taken as a strongly suggestive ocular sign of the disease. Findings of this study remark the clinical relevance of performing a complete ophthalmic examination in sick foals, in order to help in the diagnosis and prognosis of uveal diseases, as well as to guaranteeing visual soundness.
