Abstract
Purpose: To report a case of acute syphilitic posterior placoid chorioretinitis in an immunocompetent patient. Method: Interventional case report. Results: A 41-year-old male patient presented with progressive blurred vision and multiple placoid patches of chorioretinitis in both eyes. The placoid lesion improved after oral prednisolone treatment, but blurred vision persisted. Serum test showed a positive rapid plasmin reagin and treponema pallidum particle agglutination test, compatible with acute syphilitic placoid posterior chorioretinitis. The patient responded quickly and well to an intramuscular benzathine penicillin injection. Conclusion: Owing to a wide variety of presentations and a lack of pathognomonic features, the diagnosis of ocular syphilis requires a high index of suspicion. Routine survey of rapid plasma reagin is feasible for patients presenting with ocular inflammation of an unknown origin. It is important to establish an early diagnosis because such patients respond well to appropriate treatment. Thus, unfavorable results caused by unnecessary steroid use can be avoided.
