IL6 and retinal detachment: The expression of IL6, an interleukin found to prevent photoreceptors from degeneration after retinal detachment [39] as well as retinal ganglion cell apoptosis in the setting of increased intraocular pressure [34], was strongly increased (9, 24, and 18-fold at 8, 24, and 48 hours, respectively) post-ESMV treatment.
