Assessing Macular Function and Visual Field Loss

Frost & Sullivan honored AMA Optics, Inc. (Miami Beach, FL), as 2005 Ocular Diagnostic Devices Entrepreneurial Company of the Year for developing the Retinal Acuity Meter (RAM). Previously called the Illuminated Near Card, the RAM obtained FDA approval in 1995 and became commercially available in the US in July 2004. The device measures visual acuity through cataracts and is the first instrument capable of acquiring this measurement in eyes with visual field loss due to glaucoma as well as maculopathy.


The accuracy of the RAM depends on control of the illumination level, the pinhole aperture, and the visual angle. The RAM Pinhole Clip enables patients to choose the healthiest portion of their retinas when reading a vision line. Testing with the RAM can take less than a minute and requires little training. Additional benefits of the RAM, according to AMA Optics Director of Sales and Marketing Thomas Minero, include its portability, its high level of patient compliance due to its ease of use, and the prevention of surgical delays and unexpected poor outcomes
