Contact Information Available for logged-in reporters only Newswise A device created by an interdisciplinary group of researchers, including a UT Dallas professor, was recently named one of the best inventions of 2013 by Time magazine. The Argus II Retinal Prosthesis System restores partial vision to people blind from eye diseases such as retinitis pigmentosa and macular degeneration. It earned recognition as one of the 25 Best Inventions of the Year 2013 in the Nov. 25 edition of Time. It is one of five inventions featured in the accompanying video available on the magazines website. The device was developed by a group of researchers from five national laboratories, four universities and Second Sight Medical Products. Dr. Orlando Auciello, an endowed chair professor of materials science and engineering and bioengineering in the Erik Jonsson School of Engineering and Computer Science, was part of the team from Argonne National Laboratory that worked on the device. While at Argonne, Auciello worked on the fundamental and applied research to develop a special coating now known as ultrananocrystalline diamond (UNCD) film that protects the silicon microchip from being attacked by the saline in the eye. Without the layer of protection, the saline would destroy the microchip. … Continue reading →

By Marilyn Haddrill Retinitis pigmentosa (RP) is a rare, inherited disease in which the light-sensitive retina of the eye slowly and progressively degenerates. Eventually, blindness results. When retinitis pigmentosa is suspected, visual field testing likely will be conducted during or after your routine eye exams to determine the extent of peripheral vision loss. Other specialized eye tests may be needed to determine whether you have lost night or color vision. The first signs of retinitis pigmentosa usually occur in early childhood, when both eyes typically are affected. Night vision can be poor, and the field of vision may begin to narrow. When RP first starts to appear, the light-sensing cells that are responsible for vision in dim light (rods) gradually deteriorate and seeing at night becomes more difficult. During later stages of retinitis pigmentosa, only a small area of central vision remains, along with slight peripheral vision. It's very difficult to predict the extent of vision loss or how fast it will progress when you have retinitis pigmentosa. Your eye doctor will monitor the health of your retinal cells and administer tests to determine how well you can see. At some point, you may be advised to drive only during … Continue reading →

Richard L. Windsor, O.D., F.A.A.O. Laura K. Windsor, O.D., F.A.A.O. Published in Vision Enhancement Journal Retinitis pigmentosa is a term coined by Donders in 1855. It is not one disease, rather a group of retinal diseases with common attributes. The incident seems to be about one in every 4,000. It can be inherited by at least three different methods. Severity and speed of vision loss vary with each form of inheritance. The following are problems common to RP. Tunnel Visual Field Progressive loss of visual fields is a hallmark of RP. The visual field loss often begins as a donut like ring in mid-periphery. As it progresses both centrally and peripherally, the resultant tunnel vision begins to affect the patients activities, driving and mobility. Many patients still drive automobiles in the early stages of RP, but the risks for accidents increase as the field reduces. The functional field will be worse at night and in bad weather. Even RP patients in the early stages should not drive in these situations. As the field loss progresses, daytime driving must be curtailed. Studies suggest that on average, the visual field of the RP patient declines by 5% of the remaining field per … Continue reading →

Retinitis pigmentosa (RP) is an inherited, degenerative eye disease that causes severe vision impairment and often blindness.[1] The progress of RP is not consistent. Some people will exhibit symptoms from infancy, others may not notice symptoms until later in life.[2] Generally, the later the onset, the more rapid is the deterioration in sight.[citation needed] Those who do not have RP have 90 degree peripheral vision, while some people that have RP have less than 90 degree. A form of retinal dystrophy, RP is caused by abnormalities of the photoreceptors (rods and cones) or the retinal pigment epithelium (RPE) of the retina leading to progressive sight loss. Affected individuals may experience defective light to dark, dark to light adaptation or nyctalopia (night blindness), as the result of the degeneration of the peripheral visual field (known as tunnel vision). Sometimes, central vision is lost first causing the person to look sidelong at objects. The effect of RP is best illustrated by comparison to a television or computer screen. The pixels of light that form the image on the screen equate to the millions of light receptors on the retina of the eye. The fewer pixels on a screen, the less distinct will … Continue reading →

Toggle: English / Spanish Retinitis pigmentosa is an eye disease in which there is damage to the retina. The retina is the layer of tissue at the back of the inner eye that converts light images to nerve signals and sends them to the brain. RP Retinitis pigmentosa can run in families. The disorder can be caused by a number of genetic defects. The cells controlling night vision (rods) are most likely to be affected. However, in some cases, retinal cone cells are damaged the most. The main sign of the disease is the presence of dark deposits in the retina. The main risk factor is a family history of retinitis pigmentosa. It is an uncommon condition affecting about 1 in 4,000 people in the United States. Symptoms often first appear in childhood, but severe vision problems do not usually develop until early adulthood. Tests to evaluate the retina: There is no effective treatment for this condition. Wearing sunglasses to protect the retina from ultraviolet light may help preserve vision. Some studies have suggested that treatment with antioxidants (such as high doses of vitamin A palmitate) may slow the disease. However, taking high doses of vitamin A can cause serious … Continue reading →
