Smartphone Attachment Developed for Remote Cataract Screening in Underserved Communities
Scientists, in collaboration with researchers from Johns Hopkins University and Aravind Eye Hospital in India, have developed a low-cost smartphone attachment designed to screen for cataracts and other eye problems in rural communities. This device, which costs less than £150 including the smartphone, clips onto a smartphone camera and includes a magnifying lens, two small white LEDs, and a silicone scope to ensure clear images. The system allows community health workers with minimal ophthalmic training to capture diagnostic-quality eye images in the field. These images can then be reviewed remotely by ophthalmologists, decoupling the need for a specialist to be physically present at every screening. A study involving 1,093 patients across 19 rural camps in South India demonstrated an 89% agreement between remote screening using the device and in-person examinations for identifying cataracts, rising to 96% for mature cataracts. The most clinically significant finding was a 96% agreement between remote and ...
