Introduction:
Repeated eye rubbing and ocular microtrauma (F&MOR) have been identified as the main risk factors for the onset and progression of keratoconus. A questionnaire was developed and scientifically validated to provide a tool for screening and managing the behavioral and environmental components of this condition.
Methods:
A consortium of experts initially met to define a list of relevant questions aimed at profiling traits of patients coming for the first time to a National Reference Center for Keratoconus (CRNK). This questionnaire was administered twice to a prospective cohort of patients across eight centers. Statistical analyses were performed to retain only the fifteen most relevant questions. A final expert consultation using a nominal group method completed the validation process.
Results:
The finalized questionnaire includes 15 items designed to assess the risk of F&MOR. Its objective is to support clinical management and serve as a therapeutic tool for the prevention and inhibition of F&MOR in patients with keratoconus.
Conclusion:
This validated questionnaire enables ophthalmologists to standardize and strengthen preventive and therapeutic strategies for keratoconus.
