NCT ID NCT07241806

First seen Nov 21, 2025 · Last updated May 15, 2026 · Updated 19 times

Summary

This study looks at how the length of the eye and the strength of a person's glasses prescription relate to the health of the optic nerve and retina. Researchers will use a special camera (OCT) to take detailed pictures of the back of the eye in 266 adults who are nearsighted, farsighted, or have perfect vision. The goal is to better understand these connections, not to test a new treatment.
