Official title
Pilot Validation Study of Computer Administration of Vision Targeted Quality of Life Instruments
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
This study will test and compare computerized and paper versions of eye questionnaires. Questionnaires are used in medicine to gain a better understanding of how a disease can impact a person's quality of life. Computerized versions of such questionnaires are often as good as or better than paper versions, but there has been no direct comparison of the two. This study may help in the development of eye questionnaires used to understand symptoms and monitor patients in clinical trials. People 21 years of age and older with ocular surface disease (OSD) and matched control subjects without OSD may be eligible for this study. All participants undergo the following procedures: * Medical and eye history. * Vision test and examination of the front part of the eye. * Tear measurement: A small piece of paper is placed on the surface of the eye to measure the amount of tears produced. The consistency of the tears is measured by looking at how fast they evaporate from the surface of the eye. * Completion of either paper-based or computer-based version of a questionnaire 15 minutes after the eye examination and completion of the other version within 1 week at home. (Subjects who complete the paper version in the clinic are told how to access the computer version online at home or on a library computer; those who complete the computer version in the clinic are given a paper version to take home.)
