AUSTIN, Texas — The retina is the last of the four senses of sight to be lost.
But a new study suggests it is one of the best places to see the world.
The retinal is an almond-shaped organ that extends from the top of the eye to the back of the head.
It provides the most vivid sight for people suffering from retinal degeneration.
If you’ve ever wondered what it looks like to see with the rest of your body, now is the time to do it.
“Retinal vision is the most remarkable visual system in the human brain, with a very wide field of view,” said Dr. James Fiske, a professor of neurology and neurosurgery at Baylor College of Medicine.
People with retinitis pigmentosa (RP) often have poor visual acuity because their rods and cones have trouble reading fine detail in dark areas of the retina.
So the new study, published in the Journal of Vision, looked at patients with retinoid retinopathy (RRT) who underwent retinal surgery and compared the results to those of patients who had not undergone surgery.
In the retinal-neuron association study, patients with RRT were more likely to be classified as having normal vision, and had higher scores on a test that measures their visual acutiy, the researchers said.
This is a major finding because it indicates that patients with RP can benefit from retinoid therapy.
Dr. Fiskel said that although retinal vision loss can be devastating, it does not mean that you can’t see the whole world.
“People with RP have no more or less visual acuities than normal individuals, so they’re actually seeing the world better,” he said.
“The more retinal neurons you have in your retina, the better your visual acuches will be.”
The study found that patients who received the retinoids were at a higher risk of seeing a wider range of objects than those who did not.
“We found that, for example, when we asked patients with normal vision whether they would be able to see a tree or a building, they were twice as likely to say yes to a tree as a building,” Dr. Feske said.
Dr. J. David Smith, director of the Vision Research Institute at the University of Sydney and co-author of the study, said that the results of the retino-receptor therapy study could provide hope for patients with rRT.
RRT patients have been able to significantly improve their vision, which is a common feature of the disease.
However, Dr. Smith said that retinol therapy could be even more beneficial for patients suffering from RRT.
“There’s no doubt that retinoic acid has been shown to improve visual function, but there are some important limitations that must be addressed,” he told ABC News.
“Retinoic acids are made by the skin, and retinols are molecules that attach to the retinas and affect how the nerve cells in the retina work.”
But it’s also important to note that retinal function depends on the balance of the two, and a person who has poor vision with a balance issue can still benefit from the retina-enhancing drugs.
“Dr. Smith believes that retina retinal enhancement is a promising option for patients who have severe RP.”
When you’re looking for a new sight, retinal imaging can be a very useful tool, but if you have a condition where there’s no sight, or if you don’t have a very good visual acuracy, there are many other therapies that may be even better,” Dr Smith said.
