Analysis of the 17 subgroups yielded significant associations between intraocular IL-6 levels with glaucoma (2), pseudoexfoliation (PEX) syndrome (3), ocular inflammation 4, 4a1, 4b, 4b1–5), DR (5, 5a–c), macular oedema (MO) (6, 6a, and 6b), retinal vascular occlusion (7, 7a–c), retinal detachment (RD) (11), proliferative vitreoretinopathy (PVR) (12), retinopathy of prematurity (ROP) (13), and Coats’ disease (14). Here, IL6 is linked to retinal vascular occlusion.
