[The prevalence of disc hemorrhage and papillary atrophy in Beijing Eye Study].
OBJECTIVE
To evaluate the prevalence of disc hemorrhage and papillary atrophy in Beijing defined area.


METHODS
To review 4163 right eyes consecutive plain color fundus photographs of 4163 subjects (male/female = 1832/2331) who attended the eye screening.


RESULTS
The prevalence of glaucoma is 3.0% (135/4439). Disc hemorrhage was found in 42 eyes of 42 subjects (1.0%), and more frequently in women. The prevalences of papillary atrophy (alpha zone and beta zone) were 70.98% (2955/4163) and 20.95% (872/4163), respectively. The prevalence of beta zone was greater in glaucoma group than in non-glaucomatous group (Fisher's test, P < 0.01).


CONCLUSIONS
The prevalence of disc hemorrhage is low in whole population and women are easier to have disc hemorrhage with aging. Disc hemorrhage and papillary atrophy have different prevalences in defined-population study and might have close association on the early onset of glaucoma.
