Background: To determine the corneal densitometry(CD) values by using Scheimpflug imaging in myopic and hyperopic children and to compare the results with emmetropic children.

Methods: The CD measurements of the subject were obtained with Scheimpflug tomography. The values were automatically measured in standardized grayscale units over an area 12mm in diameter, which was subdivided into 4 annular concentric zones(0-2mm, 2-6mm, 6-10mm, 10-12mm) and 3 corneal depths(anterior layer: anterior 120µm; central layer: from 120µm to the last 60µm; posterior layer: last 60µm).

Purpose: The aim of this study is to perform a comparison of static and dynamic pupillometry measurements in patients with hyperopic anisometropic amblyopia and age-matched controls.

Methods: This prospective cross-sectional study consisted of 38 patients with hyperopic anisometropic amblyopia and 80 control subjects. A quantitative pupillometry system was used to evaluate the pupil characteristics of higher hyperopic eyes (Group 1), the fellow eyes (Group 2), and healthy eyes (Group 3).

Purpose: To evaluate the anterior segment biometric parameters of non-accommodative and accommodative refractive accommodative esotropia (RAE).

Methods: Eighty-one eyes of 81 patients were included in this prospective, case-control study. The patients were divided into three groups as follows: the RAE group (n = 31), the hypermetropia group (n = 25), and the emmetropia group (n = 25).
