Brief Summary:
This study will be a single-center observational prospective validation study with survey and sample characteristics comparable to similar validation studies in the literature
Pain represents a physiological response to the presence of tissue damage and is associated with numerous pathological conditions of the ocular surface
Furthermore in the presence of dysfunction of the nociceptive system ocular pain can occur chronically with neuropathic features
Pain quantification systems used to guide symptomatic therapy include the Ocular Surface Disease Index OSDI the Ocular Pain Assessment Survey OPAS and the Standardized Patient Evaluation of Eye Dryness SPEED
The OSDI assesses the presence of ocular symptoms their impact on activities of daily living and the presence of any aggravating factors Although it is used in clinical practice and research activities in a translated version it has never been validated in Italian
The OPAS studies in more detail the characteristics of pain and associated symptoms and their impact on the patients overall quality of life This instrument has neither been translated nor validated in an Italian version
The failure to validate the OSDI and OPAS questionnaires in the Italian version marks the starting point for this validative study
The SPEED questionnaire already translated and validated in Italian will be used as the Gold Standard and will allow comparison of the other instruments
Finally six questions regarding imaginary scenarios of pain experiences will be proposed to assess the individual threshold of nociceptive sensitivity taken from the Pain Sensitivity Questionnaire two for mild pain assessment two for intermediate intensity stimuli and two for intense pain situations
Therefore the primary objective of the study is to validate the Italian version of the OSDI and OPAS questionnaires while the secondary objective is to analyze the responses to the questionnaires by subgroups of general sensitivity to nociceptive stimuli
