Emerging Simplified Retinal Imaging.

Diabetic retinopathy (DR), a major microvascular complication of diabetes, has a significant impact on the world's health systems. Globally, the number of people with DR will grow from 126.6 million in 2010 to 191.0 million by 2030, and it is estimated that the number with vision-threatening diabetic retinopathy will increase from 37.3 million to 56.3 million if prompt action is not taken. Lack of early diagnosis and management is the leading cause of blindness in working-age populations The gap between demand and annual eye examinations has been a big challenge. Furthermore lack of availability of cost effective simplified retinal imaging tools has limited the diabetic retinopathy screening program in many parts of the world in last few decades. This has led to the development of innovative ideas and availability of cost effective simplified retinal imaging tools. In this chapter we will be describing some of the well known commercially available emerging simplified (Non Tabletop, Hand Held, Portable) retinal imaging tools that have potential to help in screening diabetic retinopathy with ease and without increasing financial burden.
