Background: Proliferative diabetic retinopathy (PDR) is a serious sight-threatening disease, and half of the patients with high-risk PDR can develop legal blindness within 5 years, if left untreated. This study was aimed at comparing panretinal photo

Background Angle lambda is the angle between the pupillary axis and the line of sight. It is important for accurate centration during anterior segment surgery. The purpose of this study is to identify the distribution of angle lambda and pupil center

This study obtained normative database for angle κ using Orbscan 3. The average angle κ values were 2.3 ± 1.34° in the whole sample, 2.23 ± 1.36° in myopic eyes, and 3.3 ±1.5° in hyperopic eyes. This is very important to optimize refractive s
