Purpose

Objective documentation of superior visual field loss is required for functional eyelid surgery but relies on time-consuming and resource-intensive perimetry.


Methods

A prospective cohort study of 106 patients was conducted from March 23, 2023, to December 31, 2024, at an ophthalmology center in Detroit, Michigan. Patients underwent the Color Ring Test (CRT) followed by conventional perimetry with the Goldmann visual field (GVF) test. Concordance was assessed based on improvement with eyelid taping, by either ≥12° by GVF or 1 unit by CRT.


Results

In this cohort, 203 of 211 eyes (96.2%) met GVF criteria and 171 eyes (81.0%) met CRT criteria. This shows concordance of 80.1% (95% CI, 73.7%-86.5%) and sensitivity of 81.8% (95%CI, 75.4%-88.1%).


Conclusion

This pilot study shows high sensitivity for CRT relative to conventional perimetry. This suggests that CRT may offer a rapid, low-cost screening alternative for functional visual field assessment in ptosis and dermatochalasis. Additional studies are needed to examine specificity.
