WAIKOLOA, Hawaii – The Holladay Automated Contrast Sensitivity Testing System was developed in response to the growing trend for contrast sensitivity to become a standard in vision testing, according to the manufacturer.

The automated device was developed by Jack T. Holladay, MD, and M&S Technologies. Using data buttons, the test subject reacts to onscreen gray discs or bull’s eye images to measure contrast sensitivity. The test takes about 8 to 9 minutes, but exam time may be shorter for repeat patients, Dr. Holladay said.

Incorporating the system into the clinical setting will “increase the quality of patient care you are giving,” said Joseph A. Marino, president of M&S Technologies. “The system can be used to verify the severity of the cataract and assist in deciding what lens to use. It puts a practice at the state-of-the-art.”

Dr. Holladay emphasized the repeatability of the test, which is designed to detect false positives.

“The best thing is that it is technician-free,” Dr. Holladay told Ocular Surgery News in an interview here at Hawaii 2005, The Royal Hawaiian Eye Meeting. “It saves valuable practice resources. It lets [the technician] work up that next patient.”
