Use of this new apparatus permits earlier, accurate identification of glaucoma-related problems.
Glaucoma occurs when pressure increases within the eyeball, seriously threatening vision.
The disease may make itself known by the appearance of colored rings and halos around bright objects, or by vision that remains good in front, but dim peripherally. Traditional diagnostic methods for glaucoma include measuring the pressure in the eye and testing peripheral vision. Sperling's invention goes a step beyond, and can detect glaucoma in patients who have no inkling that the disease is threatening their vision. The device works by a series of intricate steps that assess the patient's response to the color blue. Glaucoma patients lose their ability to recognize the color blue before becoming unable to detect other colors.
