Corneal Sensitivity with the Non-contact Esthesiometer as Compared to the Cotton Wisp Test in Patients with Ocular Surface Diseases

Key Points

A high likelihood of false-positive results was indicated by the cotton wisp test outcomes.
Results showed broad confidence intervals, indicating uncertainty in the test's effectiveness for ruling out hyposensitivity.
A qualitative approach questioned the reliability of the cotton wisp test for assessing corneal sensitivity.
Further evaluation of corneal sensitivity methods is essential in the context of positive cotton wisp test results.

Abstract

Our results demonstrate that the low specificity of the qualitative CW test, combined with a broad confidence interval, indicates a high likelihood of false-positive results. This suggests that a positive CW test may not reliably rule out hyposensitivity, underscoring the need for further evaluation in the setting of a positive CW test result.
