[The prevalence of disc hemorrhage and papillary atrophy in Beijing Eye Study]
1Beijing Tongren Eye Center, Beijing Institute of Ophthalmology, Affiliated Beijing Tongren Hospital, Capital University of Medical Sciences, Beijing 100005, China.
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).
Conclusion:
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.
