Purpose: : Endophthalmitis is the most feared complication of all ophthalmologic surgeries. Taking into account the opposing needs of limiting pathogen multiplication and minimizing tissue destruction, both antibiotics and anti-inflammatory drugs are needed for endophthalmitis care. The aim of our study is to study the immune response in aqueous humor of infected patients.

Methods: : In a prospective and multicenter study, aqueous humors of patients with endophthalmitis and control (cataract surgery) were collected. Multiplex immunoassay (Bioplex*) was done in order to define cytokines patterns. Twenty-seven cytokines, chemokines and growth factors were studied. Two-way ANOVA test was realized for each inflammatory marker to determine any difference between infected and control patients.

Results: : Aqueous humor was sampled in 24 patients with endophthalmitis and 88 controls. Endophthalmitis was leading to high levels of cytokines and chemokines of the Th1 (Interleukin (IL)-2, IL-15, IFN-γ, TNF-α, IL-7, G-CSF, MCP-1, IL-8, IP-10) and Th17 (IL-17, IL-6, IL-1b) ways (p < 0,0001). To the contrary, Treg markers (IL-10, IL-27) were not increased. Moreover, very high levels of VEGF and FGF were noted in aqueous humors of patients with endophthalmitis as compared to the control (p < 0,0001).

Conclusions: : Th1 and Th17 cells may play an important anti-infectious role in modulating pathogen proliferation in infected eyes, and repressing Treg cells. But this huge inflammatory response may be responsible for retinal destruction as a collateral effect. Moreover, pro-angiogenic factors are secreted in infected eyes. Antagonism of TH17 by Tregs cells and anti-angiogenic drugs could be a way to limit ocular lesion and may open new therapeutic approach by stimulating Tregs cells or repressing TH17 cells.
