New digital tool could make eye scar assessment more accurate
NCT ID NCT07458126
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tested a digital color scale to objectively measure scarring of the eye's surface in people with recurrent pterygium, a growth that can come back after surgery. Researchers took photos of 25 patients' eyes and used software to analyze the scar tissue. The goal was to see if this digital method is more reliable than the usual subjective exam.
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 digital tool could provide a more objective and standardized way to assess scarring after pterygium surgery, improving follow-up care.
- What could go wrong
- This is a small, observational study with only 25 participants. The digital scale may not prove more reliable than current methods, and results may not apply to all patients.

Who is studied
Adult patients diagnosed with primary or recurrent pterygium evaluated at an ophthalmology clinic. Slit-lamp photographs of the anterior segment are obtained during routine clinical evaluation and analyzed using digital image analysis to quantify conjunctival vascularization and colorimetric characteristics.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Adults aged 18 years or older. * Patients diagnosed with primary or recurrent pterygium. * Availability of slit-lamp anterior segment photographs suitable for digital image analysis. * Ability to provide informed consent for participation in the study. Exclusion Criteria: * Presence of other ocular surface diseases that may interfere with conjunctival vascularization assessment. * Previous ocular surgery unrelated to pterygium that may alter conjunctival anatomy. * Poor quality slit-lamp photographs that do not allow reliable digital image analysis. * Incomplete clinical data.
