Recurrent choroidal detachment following timolol therapy in previously filtered eye. Choroidal detachment post filtering surgery.

A 64-year-old patient with open-angle glaucoma was treated with timolol following two unsuccessful filtering procedures. While on timolol therapy, she developed three episodes of choroidal detachment, hypotony and shallow anterior chamber. These findings resolved upon cessation of timolol and reappeared on 3 occasions shortly after reinstitution of the beta blocker therapy.
