Regarding the influence of the extent of retinal detachment, a previous study reported that a more advanced retinal detachment is correlated with a significant increase of interleukin‐8 (IL‐8) and transforming growth factor beta‐3 (TGFβ‐3) in the vitreous humour, which indicates an inflammatory reaction due to an underlying apoptotic process in the detached outer retinal layer.24 The gene discussed is CXCL8; the disease is retinal detachment.
