Deep research and expert guides on maintaining your visual health.
Introduction Eyesight is more than letters on a chart. While visual field testing is the gold standard for glaucoma and other eye diseases, patients often notice vision problems in day-to-day life before standard tests change. For example, people may struggle to read a book in low light or feel unsafe driving at night, even if their Snellen acuity or visual field is “normal.” In this article we...
Teleophthalmology is the use of digital communication and imaging technologies to deliver eye care remotely. It allows patients to receive screenings, consultations, and some follow-up care without always traveling to a specialist’s office. The approach commonly involves taking photographs or scans of the eye at a local clinic or with portable devices, then transmitting those images to an eye care professional for review. Consultations can be synchronous, using video calls, or asynchronous, where specialists review stored images and reports later. The tools involved include retinal cameras, optical coherence tomography, secure messaging systems, and teleconferencing platforms. Teleophthalmology matters because it increases access to eye care for people in rural or underserved areas, for those with mobility challenges, and where specialists are scarce. It can speed up diagnosis, allow earlier treatment, and reduce unnecessary travel and wait times. Remote screening programs have been effective at finding sight-threatening conditions like diabetic retinopathy and referring patients for timely in-person care. Challenges include ensuring good image quality, protecting patients’ privacy and health data, and recognizing that some conditions still require face-to-face exams or procedures. When implemented thoughtfully, teleophthalmology complements in-person care by improving access, efficiency, and ongoing monitoring for chronic eye conditions.
