Objective
To determine risk factors of a disease like open-angle glaucoma (OAG) it is essential to have incidence data.
Methods
Participants of the population based Rotterdam Study were examined at baseline (1990-1992) and at follow-up (1997-1999) for the development of OAG. The criteria for the diagnosis OAG were based on ophthalmoscopic and semiautomated Imagenet estimations of the optic disc parameters and visual field testing with kinetic Goldmann perimetry. OAG was diagnosed as possible, probable, or definite.
Results
There were 5999 participants at risk. After a mean follow-up time of 6.5 years (22.826 person years) 117 developed OAG. The overall incidence rate was 5.1 per 1000 person-years and varied from 3.0 between age 55 and 60 to 9.0 above age 80.
Conclusions
The incidence of OAG increases with age and, contrary to its prevalence, does not differ between men and women.
