Abstract
PURPOSE: To analyze quantitative changes in glaucoma treatment strategies between 1997 and 2000 in France. METHODS: Numbers of ab externo trabeculectomies and other glaucoma surgeries were extracted from the national database of the French Diagnosis Related Group system, which includes data for both public and private hospitals. Mean lengths of stay and hospital costs were estimated using national cost scales published by the French Ministry of Health. Numbers of patients treated per year with latanoprost, brimonidine, or the fixed combination of dorzolamide + timolol were estimated from drug unit sales using defined daily doses for each drug. RESULTS: Between 1997 and 2000, the number of patients treated with a glaucoma drug increased from 410,000 to 734,000 patients per year. This increase was associated with the introduction of three new glaucoma drugs: 245,000 patients received latanoprost (71.0%), brimonidine (28.8%), or the fixed combination of dorzolamide + timolol (0.2%). During the same period, the surgery rate in patients receiving medical treatment declined by 47%, from 5.9% to 3.1% . The total number of glaucoma interventions declined by 4.6% (-12% in public hospitals and 0% in private hospitals). This relative stability resulted mostly from a shift from trabeculectomies to other procedures, mainly to new filtering procedures in private hospitals. CONCLUSIONS: Between 1997 and 2000, new glaucoma drugs, primarily latanoprost and brimonidine, improved intraocular pressure control and delayed surgery, reducing the glaucoma procedure rate in patients receiving glaucoma-related medical treatment by 47%.
