Abstract:
We present a patient with recurrent mantle cell lymphoma (MCL) who was treated with zanubrutinib, a Bruton's tyrosine kinase inhibitor. He subsequently developed bilateral cystoid macular edema (CME) in both eyes. This is the first report of CME in a patient with MCL who was treated with zanubrutinib. CME was refractory to topical corticosteroid therapy, but sub-Tenon's steroid injections and holding off zanubrutinib managed to decrease the CME. Treatment managed to prevent further vision loss but did not restore lost vision. The prompt ophthalmic exam is recommended for patients on zanubrutinib with decreased vision.
