Duke Researchers Developed Device To Detect Glaucoma Fast And Effective

At an exclusive interview to the FOXNews.com. Dr. Sanjay Asrani, associate professor of ophthalmology at Duke Eye Center in Durham has told that the researchers there developed an instrument that is able to detect the glaucoma decades before the disease claims the eyesight of the patients. Thus the high-resolution imaging tool is expected to bring a ray of hope to the patients fearing to lose eye sight.

The device, called fourier domain optical coherence tomography, can detect narrow angle glaucoma, which is the most serious form of the disease. Doctors said that there are no symptoms of the disease, especially of the open-angle glaucoma. But there are few symptoms of the narrow angle glaucoma that can include headaches, blurred vision and seeing colored halos or colored rings around lights in the evening. With glaucoma, the pressure in patients’ eyes can suddenly go to an extremely high level. If this attack is not treated immediately, the patient can go blind within a few hours. But the doctors said if a person is at risk for the disease, a two-minute laser treatment can prevent it altogether, 15 or 20 years earlier.

The new technology allows doctors to make a 2D cross-sectional image of the eye with high-resolution, high-speed beams of light without touching the eyeball, according to a news release. It also uses software that can zoom in on very detailed drain structures.

Dr. Asrani said,

"Because it is done with infrared light spectrum rather than artificial light, we can check the drain with the room lights on and off to know what patients experience in real dark and light settings. It's also a great tool to show the patients what we are seeing. They can see how narrow their drain is, and understand the necessity of preventive procedures such as laser surgery, which can open the drain."
