Welcome to the December 2010 edition of At-A-Glance, Lighthouse International’s low vision newsletter. Read our feature article on an exciting new clinical trial to treat macular degeneration.
Biotech Company to Use Embryonic Stem Cells to Treat Macular Degeneration
Hope may have finally arrived for people with Stargardt’s Macular Dystrophy (SMD). Advanced Cell Technology (ACT), a biotechnology company located in Marlborough, MA, has received approval from the US Food and Drug Administration (FDA) to conduct a clinical trial using retinal cells derived from human embryonic stem cells to treat patients with Stargardt’s Macular Dystrophy.
SMD is the most common form of inherited juvenile macular degeneration and is usually diagnosed in children between 10 to 20 years of age. Since the progression of visual loss is variable, some individuals may have visual acuities in the range of 20/200 (legal blindness) to 20/400. There is currently no treatment for Stargardt’s disease.
"The announcement for the beginning of clinical trials with stem cells for Stargart's Macular Dystrophy gives hope to so many that their vision may once again be restored,” said Dr. Bruce Rosenthal, Chief of Low Vision Programs at Lighthouse International. “It’s hoped that research with stem cells will turn the tide and result in stabilization and improvement in visual function.”
ACT’s clinical trial, which includes 12 patients, will determine the safety of using stem cells to treat patients with advanced SMD. “Using stem cells, we can generate a virtually unlimited supply of healthy RPE cells, which are the first cells to die off in SMD and other forms of macular degeneration,” said Dr. Robert Lanza, ACT’s Chief Scientific Officer, in a statement. “Our studies showed that the cells were capable of extensive rescue of photoreceptors in animals that otherwise would have gone blind. We hope to see a similar benefit in patients with various forms of macular degeneration.”

Ask the Expert
Q: I have been suffering from low vision and dryness of the optic nerve. Is there anything I can do?
A: Depending on what type of optic nerve disease you have, there may be treatment available. Optic nerve disease encompasses a broad range of conditions. You may also suffer from dry eyes, which is an ocular surface condition, unrelated to the optic nerve condition … Read on for the answer to this question and the rest of December’s Ask the Expert selections.
