Iris color changes less in eyes treated with unoprostone

Orlando-The incidence of iris hyperpigmentation associated with unoprostone isopropyl ophthalmic solution 0.15% (Rescula, Novartis) was about 1% in two long-term studies, a rate that compares favorably with the incidence of 10% to 20% associated with latanoprost ophthalmic solution (Xalatan, Pharma-cia) in similar patient populations, reported Bernard E.
