New eye test criteria could speed up diagnosis of vision loss cause
NCT ID NCT07623252
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study looks at whether a new set of international criteria can accurately diagnose optic neuritis—a condition that causes sudden vision loss—in Chinese patients. Researchers will enroll 500 people with acute or subacute vision loss and compare the criteria's results against expert diagnoses. No new treatments are being tested; the goal is to improve diagnostic accuracy.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- What this could lead to
- If successful, this could lead to more accurate and faster diagnosis of optic neuritis, helping doctors choose the right treatment sooner.
- What could go wrong
- This is an observational study, not a treatment trial. The criteria may not perform as well in real-world settings, and results may not apply to other populations.

Who can take part
This study's own entry requirements. Only the study team can say for certain whether you qualify.
Who is studied
Individuals with a new acute or subacute episode of visual loss or optic nerve-related visual dysfunction in one or both eyes, for whom optic neuritis is included in the initial differential diagnosis at participating clinical centers. Each participant contributes only one clinical episode to the primary diagnostic accuracy cohort.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: 1. Individuals presenting with a new acute or subacute episode of visual loss or optic nerve-related visual dysfunction in one or both eyes, for whom optic neuritis is considered a reasonable differential diagnosis by the treating clinical team at the initial clinical assessment and before final diagnostic adjudication. 2. Symptom onset of the current episode within 90 days before enrollment. Exclusion Criteria: 1\. The participant has previously been enrolled in this study. Each participant may be enrolled only once. A history of optic neuritis or recurrent optic neuropathy before the current episode is not an exclusion criterion.
