IL-6 and IL-17A levels in BE (1611.8 ± 1193.7 pg/ml and 104.3 ± 115.6 pg/ml, respectively, 100% detection of both) were respectively about 3000-fold and 58-fold, 710-fold and 19-fold, 86-fold and 18-fold, and 3.3-fold and 7.7-fold higher than those in ERM (0.53 ± 0.7 pg/ml and 1.79 ± 0.58 pg/ml, 53% and 100%), IOL (2.28 ± 2.12 pg/ml and 5.38 ± 3.18 pg/ml, 92% and 100%), sarcoidosis (18.7 ± 47.4 pg/ml and 5.81 ± 2.82 pg/ml, 93% and 100%) and ARN (484.9 ± 617.2 pg/ml and 13.6 ± 18.3 pg/ml, 100% in both). Here, IL17A is linked to sarcoidosis.
