Cataract detection using smartphone

Abstract

A cataract could be an evaporation of the ordinarily clear lens of the eye. Those having cataracts may experience seeing through their cloudy lenses which could be a bit like exploring through a frosty a fogged up window. Clouded vision caused by cataracts will create it tougher to browse websites, drive an automobile (especially at night) or see the expression on a friend's face. Most cataracts develop slowly and do not disturb sight early. However, with time, cataracts can eventually interfere with vision. There are some manual techniques to detect a cataract. An ophthalmologist or optometrist diagnoses a cataract by doing a comprehensive eye examination. The ophthalmologist uses a slit lamp camera to diagnose a cataract. By the lacking of ophthalmologist and slit lamp camera in rural areas, especially in developing country like Bangladesh are the main problem of diagnosing a cataract. There also have some automated smartphone based cataract detection techniques that will overcome these problems. In these research, we proposed a methodology that will be implemented on a smartphone (Android, iOS, Windows). This paper presents a proof-of-concept self-screening cataract detecting mobile application. It enables the public to carry out early detecting by using a smartphone with a well focusing front camera that allows self-screening to be performed by almost anyone, anytime, anywhere.
