PCLAF and atopic conjunctivitis: Therefore, in addition to the direct deleterious effects of PAF on the ocular surface epithelial cells such as apoptosis [34], corneal remodeling [35], and neovascularization [36], the further amplification of its downstream effects due to the release of cytokines make PAF a powerful inflammatory agent that is implicated in allergic conjunctivitis, pain, and neovascularization of the ocular surface [37-39].
