What to know
- VEHSS includes the percentage of people with diagnosed glaucoma who received treatment based on payment claims in administrative claims databases and medical record information in the IRIS Registry of electronic health records
- This indicator represents the percent of diagnosed glaucoma patients who received at least one instance of an included treatment during the year of observation.
- Therefore, all prevalence estimates are based on a denominator of glaucoma patients who had a visit that included a glaucoma diagnosis.
