L-671,152, a new potent water-soluble inhibitor of human carbonic anhydrase II in vitro, was applied topically to cynomolgus monkey eyes in which glaucoma had been produced by argon laser photocoagulation of the trabecular mesh-work. Intraocular pressure was measured at 0 hours, 0.5 hours, and hourly for 8 hours in eight eyes for 2 baseline days, 1 day receiving the vehicle and 5 days receiving therapy with 2% L-671,152 twice a day, after initial single-dose trials of various concentrations. Intraocular pressure was not significantly different comparing baseline and vehicle-treated days. Significant intraocular pressure reductions occurred from 1 to 8 hours after the first dose, and lasted for at least 16 hours after the second dose. The reduction in intraocular pressure became more pronounced from day 1 to day 5 at each time interval. The mean (+/- SEM) maximum reduction in intraocular pressure was 7.8 +/- 2.1 mm Hg on day 1 and 10.1 +/- 2.4 mm Hg on day 5 at 3 hours after administration, comparing the intraocular pressure in drug-treated and vehicle-treated eyes. L-671,152 has a longer duration of action than does previously studied MK-927 in glaucomatous monkeys. It appears to have great clinical potential.

D005901	Glaucoma	An ocular disease, occurring in many forms, having as its primary characteristics an unstable or a sustained increase in the intraocular pressure which the eye cannot withstand without damage to its structure or impairment of its function. The consequences of the increased pressure may be manifested in a variety of symptoms, depending upon type and severity, such as excavation of the optic disk, hardness of the eyeball, corneal anesthesia, reduced visual acuity, seeing of colored halos around lights, disturbed dark adaptation, visual field defects, and headaches.

D000287	Administration, Topical	The application of drug preparations to the surfaces of the body, especially the skin (ADMINISTRATION, CUTANEOUS) or mucous membranes. This method of treatment is used to avoid systemic side effects when high doses are required at a localized area or as an alternative systemic administration route, to avoid hepatic processing for example.
