N2 - Bacterial keratitis is an ocular emergency and is one of the leading causes of blindness worldwide. Pseudomonas aeruginosa is the most frequent causative agent of keratitis. The infectious process of P. aeruginosa is highly invasive and can rapidly lead to corneal ulcers, ocular infections (endophthalmitis), and corneal perforation. Delayed or inadequate treatment may result in complications such as corneal fibrosis and neovascularization. Platelet-rich fibrin (PRF), which contains high levels of platelets, can aid in hemostasis, cell migration, and proliferation to accelerate the wound healing process. PRF contains several growth factors, such as Platelet-derived growth factor (PDGF), Vascular endothelial growth factor (VEGF), and Transforming growth factor (TGF-β), which are released in a time-dependent manner during the wound healing process, ranging from 7 to 28 days. TGF-β regulates the expression and activity of matrix metalloproteinases (MMP-1, MMP-2, MMP-3, MMP-9) involved in wound remodeling and healing, where MMPs are regulated or balanced with tissue inhibitors of metalloproteinases (TIMP-1, TIMP-2). In previous studies, PRF was found to be effective in managing bacterial keratitis in cats. In this discussion, we explore the molecular effects of PRF as an adjuvant therapy for bacterial keratitis.
