THURSDAY, Feb. 19, 2015 – Glaucoma patients are more likely to take medications to treat their eye disease if they're prescribed generic drugs, a new study finds. More than half of Americans with glaucoma do not take their medications as prescribed, which is one of the biggest obstacles in efforts to prevent glaucoma-related blindness, according to the researchers. Open-angle glaucoma is the most common form of the disease in the United States. It's treated with drugs called prostaglandin analogue (PGA) eye drops. These drugs are very effective, but brand name PGAs tend to be significantly more costly than other types of glaucoma drugs. A generic version of the PGA latanoprost was approved by the U.S. Food and Drug Administration in 2011 and at the time was $1,300 cheaper per year than brand name PGAs. In this study, researchers analyzed data from more than 8,400 glaucoma patients. All ... Read more

THURSDAY, Dec. 18, 2014 – Prostaglandin analogue eye drops – a common form of glaucoma drug – significantly reduce the risk of vision loss in patients with the eye disease, a new study finds. British researchers led by David Garway-Heath, of the Moorfields Eye Hospital and UCL Institute of Ophthalmology in London, tracked outcomes for more than 500 people newly diagnosed with open-angle glaucoma – the most common form of the disease and one of the leading causes of blindness. About 45 million people worldwide have this type of glaucoma, and the number is expected to rise to 53 million by 2020 and 80 million by 2040, according to the researchers. However, they found that the use of latanoprost – a form of prostaglandin analogue eye drops – reduced the risk of vision loss in these patients by more than 50 percent over two years, compared to those who received an inactive placebo. ...

FRIDAY, May 24 – Drugs commonly used to treat glaucoma may cause droopy eyelids and other side effects that can interfere with vision, according to a new study. The drugs, known as prostaglandin analogues (PGAs), which are used to reduce eye pressure, have already been shown to cause blurred vision, dryness and changes in eye color, the researchers said, suggesting that the new findings could lead to labeling changes for PGAs. Doctors should be conservative when prescribing these drugs, the researchers added, particularly as a preventive measure for patients at risk for glaucoma. "The loss of periorbital fat was previously described by us in a small series of unilateral PGA users," senior study author Dr. Louis Pasquale, director of the glaucoma service at the Massachusetts Eye and Ear Infirmary, said in an infirmary news release. "Those observations did ultimately lead to a change in ... Read more
