What is being measured
The primary outcome is the main question the study is designed to answer.
Incidence and prevalence of visual conditions in the Public Service in Brazil
- The ages ranged from 0 to 99 years
- The mean age was 56.9 years
- There was a predominance of females (58.1%)
- The main reason for the consultation was low visual acuity (70%), followed by burning (26%) and itchiness (24.4%)
- Among the abnormal tests there was a high prevalence of refractive errors (73.4%) and presbyopia (59.6%)
- The cause of refractive errors was astigmatism (70.5%), hypertrophy (58.6%) and myopia (15.1%)
Measured: 6 months
