Ponatinib Inducing a Panuveitis with Choroidal Effusions and Neurosensory Retinal Detachment in a Patient with Chronic Myeloid Leukaemia

Abstract

Case summary: We present the case of a 50 year old male patient being treated for chronic myeloid leukemia by the tyrosine kinase inhibitor, Ponatinib. After 3 months of treatment, he developed a sight-threatening granulomatous panuveitis in both eyes, with choroidal effusions and neurosensory retinal detachments. Except for a positive interferon-gamma release assay suggesting previous Tuberculosis exposure, all uveitis investigations were normal. Discontinuation of the suspected causative drug led to resolution of signs and a consequent improvement in visual acuity.

Conclusion: Ponatinib use may be associated with with a uveitic phenotype that is reminiscent of Harada's disease. We compare and contrast this rare ocular phenomenon with Vogt-Koyanagi-Harada syndrome and discuss a possible immunological basis.
