摘要:
The presence of interleukin 6 (IL-6), interleukin 1 (IL-1), interleukin 2 (IL-2) and tumour necrosis factor (TNF) was investigated in vitreous and aqueous aspirates from eyes undergoing vitrectomy for the treatment of different inflammatory conditions. Cadaveric vitreous from 10 normal subjects were used as controls. IL-6 was observed in 5 specimens from eyes with idiopathic uveitis (range = 26–264 pg/ml), in 2 specimens from eyes with uveitis complicated with retinal detachment (28 and 279 pg/ml, respectively), in 6 samples from eyes with diabetic retinopathy (range = 5–480 pg/ml), in one sample from an eye with phacolytic glaucoma (1190 pg/ml) and in one specimen from an eye with Behçet's disease (366 pg/ml). Although IL-1 was detected in 80% of all the samples investigated, concentrations of this cytokine>3 pg/ml were only observed in 2 specimens from eyes with uveitis (5 and 20 pg/ml, respectively) and 2 samples from eyes with diabetic retinopathy (3 and 31 pg/ml, respectively). TNF was present in 3 specimens from eyes with uveitis (range = 2–24 pg/ml) and 1 sample from eyes with diabetic retinopathy (4 pg/ml), but was not detected in the eyes with phacolytic glaucoma or Behçet's disease. IL-2 (≤0.1 U/ml) was detected in one sample from an eye with uveitis, one specimen from an eye with uveitis complicated with retinal detachment and 2 samples from eyes with diabetic retinopathy. None of the cytokines measured were detected in any of the control vitreous. The present observations suggest that cytokines, particularly IL-6 and IL-1, may act as local amplification signals in pathological processes associated with chronic eye inflammation.
