Objective To investigate the morbidity of ocular fundus diseases in Tibetan above 40 in Maqin county, Qinghai Province. Methods A total of 2511 Tibetan above 40 in Maqin county, Qinghai Province were seelected by cluster sampling method. The sampling survey of ocular fundus diseases was performed on the individuals with indirect ophthalmoscope, and the results were compared with the domestic existing epidemiological data. Results Two hundred and thirty five (9.35%) cases were found to have abnormal ocular fundus, and the blindness rate due to the abnormal ocular fundus was 20.5% (80/391 eyes) which was lower than the blindness rate due to cataract (52.5%). Low vision and blindness led by ocular fundus diseases were found in 155 eyes (65.96%)，including 74(47.74%) with age-related macular degeneration (AMD) and 23 (9.79%) with retinoangiopathy. Conclusions The morbidity of ocular fundus disorder is higher in high plateau than that in backland; AMD and retinoangiopathy are the main diseases leading to blindness.
