Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
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.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
adult patients (aged 18 years or older) with high myopia
The study population consists of adult patients (aged 18 years or older) with high myopia, defined as an axial length greater than 26 mm or a refractive error exceeding -6.00 diopters (D). Participants must be able to fixate for imaging procedures.
No interventions assigned to this group
