Acute syphilitic posterior placoid chorioretinopathy: A case report.

A 25-year-old male presented with a complaint of acute visual loss in his right eye for two days. There was a history of visual loss in the left eye six months ago. Comprehensive eye examination showed evidence of posterior uveitis, and a placoid lesion on the right fundus. Further physical examination showed maculopapular rashes on the upper back which was highly suggestive of syphilis. Blood tests for venereal disease research laboratory (VDRL) test and fluorescent treponemal antibody absorption (FTA-ABS) test were ordered, which were both positive. Ocular syphilis should be suspected in all cases of uveitis. Early diagnosis and prompt treatment with appropriate antibiotics can prevent permanent visual loss.
