Feasibility Analysis of Teleophthalmology Diagnosis and Referral in Remote Areas of Taiwan

Remote areas of Taiwan lack routine and specialized ophthalmology services. This study aimed to analyze feasibility of teleophthalmology service for diseases diagnosis and referral in remote areas of Taiwan. A retrospective study of medical records from 11 remote teleophthalmology clinics in the Taitung area of Taiwan was conducted from May 2020 to December 2021. Vision and intraocular pressure were checked. Ophthalmic imaging was performed by local trained nurses using a hand-held ophthalmoscope and slit lamp biomicroscope. The images were transmitted by telemedicine system to a medical center. Consultation was conducted via face-to-face real-time video calls. Ophthalmologists in the medical center provided diagnosis and treatment advice based on the real-time images and interactive history taking via the telemedicine system. All the images and data were collected and well-reviewed by ophthalmologists in the medical center, and disease prevalence and referral were analyzed for the program. A small-scale satisfaction questionnaire survey was conducted for efficacy evaluation of the program. A total of 1,401 medical records from 1,094 patients were collected and screened. Patients' ages ranged from 9 months to 94 years, with a mean age of 57.27 (standard deviation ±20.47) years. The most frequent ophthalmologic diagnosis was dry eye disease (20.2%), followed by conjunctivitis (12.4%). Among 322 patients with underlying diseases of diabetes mellitus, 59 patients (18.3%) were diagnosed with diabetic retinopathy. Major diagnosis was made in 102 patients (7.3%) and referral to hospital for further management was suggested. This program had high overall satisfaction score of 89% (mean 4.43 ± 0.52 points) in satisfaction questionnaire survey. Teleophthalmology provides an alternative tool for ocular disease diagnosis and screening for patients in remote areas, especially during the COVID-19 pandemic. This service helps to detect major but undiagnosed diseases and promotes health care accessibility and availability in remote areas that lack specialists.
