OBJECTIVE: To evaluate the prevalence of disc hemorrhage and parapapillary 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 parapapillary 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 the glaucomatous group than in the non-glaucomatous group (Fisher's test, P < 0.01). CONCLUSION: The prevalence of disc hemorrhage is low in the whole population and women are easier to have disc hemorrhage with aging. Disc hemorrhage and parapapillary atrophy have different prevalences in defined-population study and might have a close association with the early onset of glaucoma. LA: Chinese
