简要总结
Globally1.1 billion people suffer visual impairment.1 The causes earlier were more infectious diseases like trachoma and onchocerciasis.2 But in the recent days due to increase in life expectancy, and widespread adoption of western diets/lifestyles non-communicable disease are on rise. Consequently, posterior segment diseases (PSD) such as diabetic retinopathy (DR), glaucoma, and age-related macular degeneration play a major role in causing visual impairment.2
From 1990 to 2015 visual impairment due to DR has nearly doubled from 1.4 million to 2.6 million and glaucoma has increased from 3.0 million to 4.0 million. This rising global burden of eye diseases is increasing both health and financial challenges for patients and the healthcare system.2 Approximately 47% of the population in developing countries are still living in rural or resource-limited areas where trained ophthalmologists are not available readily.3
Posterior segment screening is crucial for early diagnosis and treatment of PSD.4 Advances in technology and optics have led to the widespread use of fundus cameras, especially for screening in peripheral outreach services. There are a lot of fundus cameras in the market but are quite costly and not always affordable.
Along with this another modern era problem is electronic waste. LabSD (Inc., 7F, C Tower, Samsung Electronics Seoul R&D Campus, 33, Seongchon-gil, Seocho-gu, Seoul, Republic of Korea) and Samsung (have successfully combined these problems and made a product, EYELIKEâ„¢ digital ophthalmoscope, out of recycled polycarbonate materials and repurposed Samsung phones for making fundus camera that is portable and can be easily used by any trained technician.
We expect that this innovative fundus camera using upcycled smartphone will be helpful in strengthening the screening process and early detection, and referral of patients with posterior segment pathologies. If the device proves good in terms of sensitivity and specificity, in future it can be employed in capturing PSD in remote eye care settings such as vision centers and outreach camps**.**
