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.
