Standardized Vision Testing for Clinical Trials

Eye care-related clinical trials typically occur across a variety of locations, with many different clinicians administering the test on a wide range of patients and test subjects. The clinical trials testing regimens require standardization from location to location and ease of use for the test administrator and patient. Without standardized testing and easy to capture repeatable and accurate data, the clinical trials may provide little usable results. Low maintenance of the test instruments is also a definite plus since the locations are often spread across the country and around the world. VectorVision products are widely selected for use in clinical trials because they automatically standardize the test conditions and make it easy to capture the data; and are extremely low maintenance.

Both the CSV-1000 and ESV-3000 have been selected for a number of clinical trials.

The CSV-1000 has been used for trials to measure contrast sensitivity, glare sensitivity, ETDRS acuity and low contrast acuity. Visit this page to learn more about the use of the CSV-1000 in clinical trials.

The ESV-3000 has been used in clinical trials to measure ETDRS acuity, low contrast acuity and letter contrast sensitivity. When ETDRS testing is required from 4 meters in clinical trials, the ESV-3000 is often used. The device is also used in conjunction with the ELCT for trials which measure letter contrast sensitivity in patients. Visit this page to learn more about the use of the ESV-3000 in clinical trials.
