COMPANIES OFFER NEW VISUAL FIELD TECHNOLOGY

Konan Medical USA has received 510(k) clearance from the U.S. Food and Drug Administration for objectiveFIELD, a perimeter designed to assess the human visual field in a completely objective and non-contact manner. Unlike the conventional method currently in use in most eye doctors’ offices, there is no need for any manual input from the patient. Using a patented multifocal pupil objective perimetry method (mfPOP), objectiveFIELD tests both eyes simultaneously in only a few minutes.

Konan acquired objectiveFIELD from the Australian National University (ANU), which clinically researched the device over a 12-year period that included more than 16,000 examinations. These included normal eyes as well as those in patients who have glaucoma, macular degeneration, diabetic retinopathy, multiple sclerosis, epilepsy, migraine, concussion, and other neuro-vision conditions. (The objectiveField is not cleared for specific diagnosis of these conditions.)

The perimeter includes features licensed from Seeing Machines and is the brainchild of researcher Ted Maddess, PhD, and his team “The Maddess Group—Diagnostics for Eye Diseases,” at the John Curtin School of Medical Research. Intellectual property acquired by Konan includes 15 issued patents in nine countries, six patents in process, and clinical data to support a wide range of important diagnostic indications.

The objectiveFIELD has also been clinically researched for use in concussion assessment at ANU that are thought to have visual-field manifestations.  Recently Gordon Waddington, Professor of Sports Medicine at the Australian Institute of Sport, and Professor Braden McGrath, at the University of Canberra, additionally have helped conduct novel measures of visual function related to concussion injuries with objectiveFIELD technology.

Konan will showcase the objectiveField next month at the American Academy of Optometry (Booth 1827) in San Antonio, TX. Go to KonanMedical.com.

COMPACT PERIMETER

Also new in the visual field testing arena is the Smartfield contact perimeter from OCULUS. The new Smartfield has been optimized to test for functional impairment of the central visual field, but it also can be used for peripheral measurements.

The Smartfield performs standard automated perimetry using an ultra-high luminance LCD display. Its short measurement times make it suited for standard screening methods. In addition, the control software offers a wide array of state-of-the-art measurement procedures for diagnostic and follow-up examinations.

With its compact design, the new OCULUS perimeter requires little set-up space. It can be operated in rooms with normal lighting conditions, saving the need for a darkroom. Also, a carrying handle makes the perimeter portable.

The new Smartfield comes with a translucent lateral eye shield, eliminating the need for an eyepatch, and patients with presbyopia require no refractive correction prior to testing.

The new Smartfield works entirely without moving parts for reduced maintenance costs and a longer service life. Go to OculusUSA.com.
