Summary

This study aims to compare the accuracy and reliability of anterior chamber depth (ACD) measurements obtained using three imaging modalities: anterior segment optical coherence tomography (A-S OCT), ultrasound biomicroscopy (UBM), and the Pentacam Scheimpflug imaging system. The research focuses on high myopic patients and evaluates the consistency and correlation of these measurements with the degree of myopia.

Detailed description

The research is a cross-sectional, prospective, observational cohort study conducted in ophthalmological settings at Assiut University Hospital, Elforsan Center, and Tyba Center. It investigates the anterior chamber depth (ACD) in high myopes using three advanced diagnostic imaging tools: Anterior Segment Optical Coherence Tomography (A-S OCT): A non-invasive imaging technique for high-resolution cross-sectional imaging of the anterior segment. Ultrasound Biomicroscopy (UBM): An imaging method that uses high-frequency ultrasound to visualize anterior segment structures. Pentacam HR (Scheimpflug Imaging System): A device that provides three-dimensional imaging of the anterior chamber. The primary objective is to determine the mean differences in ACD measurements among these devices. Secondary objectives include assessing the correlation between ACD measurements and the degree of myopia, as well as evaluating the repeatability of measurements for each device.
