Title : Universal slit lamp-mounted mobile adapter with 20D lens for fundus photography: A frugal innovation
Abstract:
Fundus photography is an arduous task using 90 diopters (D) in one hand and smartphone attached on an eyepiece of a slit-lamp biomicroscope. Similarly, with 20 D lens, the filming distance is adjusted by moving the lens or mobile forward or backward makes it difficult to adjust and focus image in busy ophthalmology OPDs. Moreover, fundus camera costs thousands of dollars. Authors describe a novel technique of performing fundus photography with 20 D lens and a universal slit-lamp-mounted mobile adapter made from trash. By the use of this simple yet innovative fugal innovation, primary care physicians or ophthalmologists without a fundus camera, can easily snap a fundus photo and subject them to digital analysis by retina specialists across the world. This will help in simultaneous ocular examination and fundus photos taken via mounted 20 D on a slit-lamp itself and also reduce the need for unnecessary retina referrals to tertiary eye care center.
