Beijing Eye Public Health Care Project

Area of Science:

• Ophthalmology
• Public Health
• Telemedicine

Background:

• The Beijing Eye Public Health Care Project aimed to establish a telemedicine-based eye care system for elderly residents in rural Beijing.
• This initiative served as a preparatory step for implementing advanced ophthalmic public health services in China.

Purpose of the Study:

• To assess the feasibility of a large-scale ophthalmic screening program utilizing telemedicine.
• To determine the prevalence of visual impairment and its causes among the elderly population in Greater Beijing.

Main Methods:

• A population-based study involving over 560,000 elderly participants (aged 55-85) in rural Beijing.
• Ophthalmic examinations were conducted by trained technicians, with visual acuity assessment and ocular fundus photography for those with reduced vision.
• Telemedicine was employed to transmit images for diagnosis of visual impairment causes by a central reading center.

Main Results:

• A participation rate of 81.3% was achieved, with 9.62% of subjects exhibiting visual impairment in at least one eye.
• Cataract was the leading cause (3.41%), followed by other macular diseases (0.48%), glaucoma (0.29%), pterygium (0.25%), and diabetic retinopathy (0.16%).
• 1.04% of participants required cataract surgery, with 91.7% achieving improved visual acuity post-operation.

Conclusions:

• The Beijing Eye Public Health Care Project demonstrated the effectiveness of a telemedicine-based infrastructure for mass ophthalmic screening in a large elderly population.
• The study confirmed cataract as a primary cause of visual impairment, alongside significant prevalence of retinal diseases like diabetic retinopathy and glaucoma.
