pci-32765 and Hyphema

Ibrutinib is a small-molecule drug approved for the treatment of haematological disorders and is known to be associated with visual disturbances, but uveitis has not yet been reported as an adverse effect of this medication. We present two cases of ibrutinib-associated severe uveitis in patients with chronic lymphocytic leukaemia.. Our first case is a 65-year-old woman who presented with acute onset of bilateral fibrinous anterior uveitis 1 day after starting ibrutinib. Her vision was hand movements in the right eye and 20/120 in the left with hyperaemic discs and subretinal fluid. Ibrutinib was stopped and she experienced a significant improvement under local and oral steroid treatment. The second case is a 64-year-old male with subacute onset of bilateral hypertensive anterior uveitis with pupillary seclusion and right eye hyphaema. He was on ibrutinib for the past 9 months. His vision at presentation was 20/80 and 20/60 for the right and left eye, respectively. He responded poorly to local steroid treatment until ibrutinib was stopped due to cardiac side-effects, after which his uveitis resolved and treatment was stopped.. The temporal association between changes in ibrutinib treatment and our patients' ocular inflammation suggests a causative link. Ibrutinib increases Th1-based immune responses which is proposed as a mechanism for drug-induced uveitis. Its antiplatelet effect may explain the fibrinous nature of the inflammation and hyphaema.
