Validation of Computerized Vision-Targeted Quality-of-Life Questionnaires
NCT00678860 · View on ClinicalTrials.gov ↗
Study Summary
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.)

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT00678860
The ClinicalTrials.gov registry entry for NCT00678860 describes a study currently listed as completed. It is categorized as an unspecified phase, which is the standard way researchers label where a study sits along the investigational pathway from early safety work through later efficacy and post-marketing evaluation. The registered enrollment target is 147 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is National Eye Institute (NEI), which has 214 total studies on file at ClinicalTrials.gov, and sponsors are the parties responsible for study design, oversight, and regulatory filings.
The record links to 1 condition, with Eye Disease appearing as the primary indexed condition, and to 0 interventions. Interventions can include drugs, devices, procedures, behavioral programs, or observational arms, and each is tracked as a separate registry field so that downstream queries can filter accurately. When a trial lists multiple interventions, it usually reflects a multi-arm design or a comparison protocol rather than a single treatment being tested in isolation. The brief summary published in the registry is the clearest source of protocol intent and should be read before drawing conclusions from any sidebar tags.
Geographic footprint matters for practical reasons: NCT00678860 reports 1 study location spanning 1 distinct geographic area — top geographies include Maryland. A larger site network tends to correlate with broader recruitment capacity, but it does not imply anything about study quality, and site-level enrollment status can diverge from the overall registry status shown above. Every data point on this page comes from the public ClinicalTrials.gov dataset and is reproduced here for reference only; it is not a medical recommendation, an endorsement of the sponsor, or an invitation to enroll. Verify current status, eligibility criteria, and contact details directly at ClinicalTrials.gov, and discuss any participation decision with your own healthcare provider.
