Current treatments attempt to reduce this intraocular pressure through the daily application of eyedrops, or through surgery or implantation of medical devices, but these treatments are often unsuccessful. The most common treatments for glaucoma are eye drops and, rarely, pills. Most cases can be controlled well with these treatments, thereby preventing further loss of vision. Glaucoma is usually treated with eye drops, although laser treatment and surgery can also be used. Chair in the School of Chemical and Biomolecular Engineering at Georgia Tech, to use a tiny hollow needle to inject a polymer preparation into a structure just below the surface of the eye called the suprachoroidal space (SCS). The research, which was supported by the National Eye Institute and the Georgia Research Alliance, was published Dec. 7 in the journal Advanced Science. There is a lack of accepted safety for use under medical supervision. “The holy grail for glaucoma is an efficient way to lower the pressure that doesn’t rely on the patient putting drops in their eyes every day, doesn’t require a complicated surgery, has minimal side effects, and has a good safety profile,” said Ross Ethier, professor and Georgia Research Alliance Lawrence L. Gellerstedt Jr. Now, researchers from Georgia Tech have developed a procedure that may replace all those treatments with a twice-a-year injection. The effects of glaucoma are irreversible, so treatments for the condition are predominantly aimed at slowing the rate of vision loss or maintaining current vision. This research was supported by a grant from the National Eye Institute (R01 EY025286) and by the Georgia Research Alliance. Prescribing Information, Brand name:  Corgard, Brand names:  The possible treatment, which could become the first non-drug, non-surgical, long-acting therapy for glaucoma, uses the injection of a natural and biodegradable material to create a viscous hydrogel — a water-absorbing crosslinked polymer structure — that opens an alternate pathway for excess fluid to leave the eye. “We believe the injection could be done as an office procedure during routine exams that the patients are already getting. This group includes In the study, the researchers, including veterinary ophthalmologist and first author J. Jeremy Chae, did not observe significant inflammation resulting from the procedure. Animal reproduction studies have shown an adverse effect on the fetus and there are no adequate and well-controlled studies in humans, but potential benefits may warrant use in pregnant women despite potential risks. Treatment for other types of glaucoma may include: Some patients might benefit from using preservative-free formulations of long-term glaucoma drugs including those with aniridia, allergic tendencies, and corneal pathology. North Avenue, Atlanta, GA 30332 Often used as a short term measure for controlling very high intraocular pressure prior to more definitive treatment such as laser treatment or glaucoma surgery How does it work?

Glaucoma damage is caused by excess pressure in the eye that injures the optic nerve. The possible treatment, which could become the first non-drug, non-surgical, long-acting therapy for glaucoma, uses the injection of a natural and biodegradable material to create a viscous hydrogel — a water-absorbing crosslinked polymer structure — that opens an alternate pathway for excess fluid to leave the eye. The best treatment for your glaucoma will depend on the type you have, its severity, and how well you respond to drugs, laser treatment, or surgery. Care and Treatment.
