Applying 2 mA for ten minutes, Baum was able to achieve significant concentrations of three antibiotics — buy antibiotics online, Quigley says this is not reasonable. While he was a resident, he and a colleague, Alfred Sommer, MD, now also a faculty member at Hopkins, began grappling with the question of how to detect glaucoma earlier. Building on the work of William F. Hoyt, MD, out at the University of California, San Francisco, School of Medicine, those two began using red-free light to examine the retina. Hoyt had found that using red-free light and a common ophthalmoscope he could detect nerve damage in the retina (Invest Ophthalmol Vis Sci 1973;12: 814-829).
Since they began, Quigley has used electron microscopy to examine tissue from more than 100 eyes from patients with elevated intraocular pressure. Those patient’s conditions ranged from good visual acuity, and normal appearing optic disks and retinal nerve fiber layers, to blindness, and retinas devastated by glaucoma. He has developed a glaucoma model in primates that he used to study the progression of retinal nerve cell damage. And he has examined more than 1500 patients, about 1000 with elevated pressure, about 250 with glaucomatous visual deficits, and about 250 controls.
