Cytokine profiles in aqueous humour were studied in relation to corneal disease and subsequent corneal graft survival or rejection. Cytokine levels in samples obtained from eyes with clear grafts (n = 59) were all within the normal range. At the time of penetrating keratoplasty (n = 146), intraocular levels of IL-6 were increased in 38% (50/131), most markedly in eyes with previous allograft failure or herpetic stromal keratitis. The level of IL-10 was increased in 1 eye (n = 144) and of IL-4 and IFN-gamma in none. During rejection (n = 10), the levels of IL-6 in aqueous humour were increased in 75% (3/4), of IL-10 in 50% (3/6), of IL-4 in none (0/4) and of IFN-gamma in 40% (2/5). In conclusion, the levels of total protein and IL-6 were increased prior to penetrating keratoplasty in eyes with previous inflammation. These results could however not predict the final outcome of the graft. Increased intraocular levels of IL-6, IL-10 and IFN-gamma were observed during rejection
