Ophthalmologists Discuss Methods to Help Physicians See What Patients Can’t See: Glaucoma Detection (part 5)

Quigley says he has found that the optic disk shows evidence of cupping early, a condition long suspected but never demonstrated. As the cells die, they no longer support the meshwork of collagen and astrocytes that makes up the disk. Hence, the disk begins to fall back behind the eye, cupping. Quigley says he hopes it will be possible for trained ophthalmologists to recognize cupping with an ophthalmoscope examination.

Using the red-free light, the ophthalmologist can observe cell atrophy in the back of the retina long before perimeter testing using current methods shows visual deficits (Arch Ophthalmol 1977;95:2149-2156). Whereas healthy areas show the striations of the individual nerve fibers traveling along the retina, in the diseased areas the striations are gone and the area looks “matte,” he says.

Quigley stresses that his group of 1500 patients needs to be followed up for another two to three years before he really has evidence that the loss of striations and cupping are early signs of a progressive disease. But he says, “there is an unmistakable impression from the large amount of data already collected that the examination method we advocate will detect that a considerable minority of early glaucoma patients have damage to their eyes requiring therapy.” It’s time for you to save some of the money every time you purchase cialis online pharmacy click here enjoying high level of service and amazingly cheap medications that can always be relied upon no matter which medical problems you have.
