Analysis of Risk Factors of Diabetic Retinopathy

"1. The Slit lamb is a biomicroscope. It emits a beam of light that can be varied in height and width. It allows visualization of the anterior segment of the eye. With auxiliary lenses, the examiner can also view the posterior segment. These lenses are simple, affordable, and portable. Although high-end devices like fundus cameras and optical coherence tomography have revolutionized how practitioners detect eye diseases, they can never replace these handheld lenses.~2. OCT is a noninvasive method that yields a cross-section image of the retina by exposing the eye to near-infrared light. Specifically, an emitted light beam is scattered and reflected back by the retinal surface as well as its different layers."
