ClinConnect Summary

This clinical trial is studying how accurately three different imaging methods can measure the depth of the front part of the eye, known as the anterior chamber depth (ACD), in patients with high myopia, or severe nearsightedness. The researchers will compare results from three techniques: a special type of imaging called anterior segment optical coherence tomography (A-S OCT), ultrasound biomicroscopy (UBM), and the Pentacam imaging system. The goal is to see how consistent these measurements are with the level of nearsightedness in these patients.

To participate in this trial, you must be at least 18 years old and have high myopia, meaning your eyeball is longer than normal (more than 26mm) or your vision is significantly affected (greater than -6.00 diopters). You also need to be able to focus your eyes during the imaging tests. However, if you have had eye surgery, any eye injuries, certain eye diseases, or find it difficult to focus, you may not be eligible. If you join the study, you can expect to undergo a few imaging procedures to help researchers gather important data about eye measurements in high myopic patients, contributing to better understanding and treatment options in the future.
