Immunomodulatory role of perfluorane in the preoperative preparation of patients with rhegmatogenous retinal detachment

: The paper presents the results of studying the effect of 10% perfluorane (PF) emulsion intravenously injected 1-2 days before surgical treatment for rhegmatogenous retinal detachment on the levels of the cytokines IL-1beta, TNF-alpha, IL-6, and IL-4 in the serum and subretinal fluid of patients. PF infusion was found to exert an immunomodulatory effect that favored a short-term increase in the serum level of proinflammatory cytokines (IL- 1beta and IL-6) at week 1 and TNF-alpha on day 1) with their gradual normalization. The subretinal fluid showed recovery of the mechanisms for local immunological reactions; eye inflammation reduced due to the decreased production of proinflammatory cytokines and simultaneously the elevated level of the anti-inflammatory cytokine IL-4.
