The use of the steroid prednisone and other medications can sometimes lead to cataracts. Although many cataracts are not significant enough to require treatment, surgical removal of cataracts is usually safe and effective, resulting in improvement of vision.

Dr. Shruti Sharma of the Center for Biotechnology and Genomic Medicine has a $1.5 million grant from the National Eye Institute to look at basic research into blocking inflammation among epithelial cells in light-sensing retina in the eye, Sharma is looking at a well-known agent in inflammation called interleukin-6 that can affect those cells even though they lack the receptor normally needed for such interaction, an effect called trans-signaling. While that effect had been known for a while it is not something that researchers had focused on in the past, she said. Sharma is looking at an experimental drug that in her early work seems to have blocked that type of action in those cells, using it both in the lab in human cells in the same kind of environment that is there in the eye and in a mouse model of diabetes. The hope is to prevent the barrier disruption to the cells that can cause them to become leaky and create inflammation, an early hallmark of the disease. The mouse model allows Sharma to test the compound in both late and early stages of the disease to see if it she can prevent diabetic retinopathy from happening, she said. Separately, the compound is being tested in human clinical trials in rheumatoid arthritis, which is also promising, Sharma said. Im more excited because I am re-purposing this drug, she said. I am not trying to develop a new drug. But that potential is why Augusta University has translational programs to try and bring those promising research ideas to the clinic, said Nussbaum , chair of the Department of Ophthalmology.

The following factors may increase a person’s chances of developing cataracts: Exposure to lead – lifetime lead exposure may increase the risk of developing cataracts, scientists from the National Institute of Environmental Health Sciences, USA revealed.
