Observations from multimodal ophthalmic imaging suggest the retinal pigment epithelium and retinal vasculature are often involved. Molecular profiling of biopsies from patients with syphilis involving the eye and brain indicates multiple leucocyte subsets infiltrate the posterior eye, and highlights the role of monocytes and macrophages in promoting inflammation. Aqueous and cerebrospinal fluid samples from patients with ocular syphilis contain high levels of inflammatory mediators, including C-C motif chemokine ligand (CCL) 2, C-X-C motif chemokine ligand (CXCL) 8, interleukin (IL)-6, IL-12, and tumour necrosis factor (TNF). Macrophages and dendritic cells exposed to the causative bacterium, Treponema pallidum, increase the production of pro-inflammatory cytokines, such as IL-1β, IL-6, and TNF. Toll-like receptor activation and nuclear factor of kappa light chain enhancer of B-cells (NFκB) signalling in non-ocular human cells play prominent roles in upregulating inflammatory molecules, and altering interactions between leucocytes and epithelial or endothelial cells; similar cellular and molecular changes at the outer and inner blood-retinal barriers could contribute to retinal inflammation in ocular syphilis.

He was referred to our hospital approximately one month after the injury; this first visit was defined as Day 0 (202X/11/27). At presentation, best-corrected visual acuity was 1.0 in the right eye.
