Timolol therapy in secondary angle-closure glaucoma post penetrating keratoplasty.

Timolol maleate (o.25% or 0.5% twice a day) was used in 13 eyes of 13 patients with secondary angle-closure glaucoma post penetrating keratoplasty uncontrolled on miotics, carbonic anhydrase inhibitors, or both. When added to each patient's current regimen, tomolol controlled 9 of the 13 eyes that no longer required cyclocryotherapy, and it was well tolerated locally and systemically. Its ocular hypotensive effect appears to supplement miotics and carbonic anhydrase inhibitors.
