As 2014 comes to a close and 2015 approaching, we will see phenomenal new studies on retinal diseases such as macular degeneration, diabetic retinopathy, glaucoma and cataracts. With the ever changing technologies and the findings from those studies scientists are discovering new treatments and therapy’s and possibly of a cure for all vision disorders wiping out Blindness. One new study that was recently concluded,  tested the effecetiveness of HIV/AIDS drugs to treat macular degeneration. The test subjects were mice and also contained human retinal cells. – MDA

A key discovery has shown that an anti-HIV drug can help treat age-related macular degeneration among the elderly. A study published today in the journal Science by an international group of scientists, led by the laboratory of Dr. Jayakrishna Ambati, professor & vice chair of the Department of Ophthalmology & Visual Sciences at the University of Kentucky.
It appears that HIV/AIDS drugs that have been used for the last 30 years could also be redirected in order to treat age-related macular degeneration (AMD), along with other inflammatory disorders, due to a previously undiscovered intrinsic and inflammatory activity those drugs possess.
AMD is a progressive condition that is up to 90 percent untreatable and is a leading cause of blindness in the elderly worldwide. The two forms of AMD, wet and dry, are classified based on the presence, respectively the absence of blood vessels that have invaded the retina. Macular degeneration causes cells to die in the macula, a part of the eye located near the center of the retina that permits vision in fine detail.
A detailed understanding of the molecular mechanisms underlying wet AMD has led to several robust FDA-approved therapies. In contrast, there are no approved treatments for dry AMD yet.
HIV drugs called nucleoside reverse transcriptase inhibitors (NRTIs), including AZT and three others, blocked age-related macular degeneration in mice and also worked well in experiments involving human retinal cells in the laboratory……
