Inherited retinal disorders affect millions of people worldwide (1). With more than ten types of diseases and around 200 identified genes, is considered a complicated disease (2). As a member of inherited retinal disorders, retinitis pigmentosa (RP) is a progressive rod and cone photoreceptor degradation that leads to tunnel vision, night blindness and finally complete blindness. Disease prevalence range from 1 in 3000 to 1 in 7000 individuals (3). The disease inherit in autosomal recessive (50-60%)

Genetic Disorder: Retinitis Pigmentosa Retinitis pigmentosa(RP) is an inherited, degenerative eye disease that causes severe vision impairment due to the progressive degeneration of the rod photoreceptor cells in the retina . Retinitis pigmentosa is one of the most common inherited diseases of the retina, affecting 1.5 million people worldwide. Up to 150 mutations are known to cause retinitis pigmentosa, which includes three genetic inheritance patterns- autosomal dominant inheritance, autosomal

The study proposed herein aims to accomplish the following: To determine the optimal exposure, gamma, contrast, and brightness corrections necessary to increase the perceived contrast of images by individuals affected by Retinitis Pigmentosa (RP) and to determine the optimal image overlay of input signals corrected at both high and low thresholds such that perceived contrast is maximized. Additionally, this study will develop an I/O system of minimal necessary size responsible for image processing

Retinitis pigmentosa is a group of inheritable diseases that is characterized by gradual deterioration of the photoreceptors in the retina. The photoreceptor cells in the retina, rod cells, are light sensitive cells that are able to sense low levels of light. The frequency of retinitis pigmentosa is one in four thousand births (Deng et al., 2015; Fahim et al., 2012; Haddad et al., 2016; Shu et al., 2012) People affected by retinitis pigmentosa will typically exhibit symptoms of night-blindness first

on low vision assessment in Retinitis Pigmentosa. Introduction : Retinitis Pigmentosa is a group of inherited diseases that damage the light-sensitive rods and cones located in the retina, the back part of our eyes. Rods, which provide side and night vision are affected more than the cones that provide color and clear central vision. The prevalence of Retinitis Pigmentosa worldwide is approximately one in 4000. Up to one-quarter of all patients with Retinitis Pigmentosa will become legally blind

Retinitis Pigmentosa (RP), also known as rod cone dystrophy, is a rare genetic disease that affects the retinas in the eyes. In the United States, it affects 1 in 4,000 people making it the most common inherited retina disease (Nash, et al., 2015). This disease usually leads to blindness because of the deterioration of the light-sensing cells in the retina. Within the retina, there are cells called rods and cones. For people who have RP, the rods, which are responsible for night and peripheral vision

A patient that is diagnosed with retinitis pigmentosa (RP), takes place in the retina lined the back inside wall of the eye. The cells within the retina captures and processes images transmitted through the optic nerve to the brain. Patients whose diagnosed with RP experience a gradual collapsing in their vision because retinal photoreceptor cells have died. The cause of Retinitis pigmentosa is due to the harmful changes in any one or more than 50 genes. The genes are carried by instructions that

Seeing the light: Smart glasses enhance vision for partially blinded people Visually weakened people could recover a degree of spatial awareness, cheers to some specially-developed smart glasses. Smart glasses that can benefit people with partial visualization to pilot and evade walking into obstacles have been developed by researchers at Oxford University. The smart glasses, which contain of a video camera attached on the frame of the glasses and a computer processing component that is slight

visually impaired. However, recent technological breakthroughs have allowed scientists and doctors to test out possible solutions to a particular niche in the blindness spectrum: degenerative retinal diseases. Degenerative retinal diseases such as Retinitis Pigmentosa (RP) attack the retina exclusively. Because of that exclusivity, the other structures in the eye are typically not compromised. Therefore, the use of a retinal implant or prosthetic device to restore functional “vision” is possible. While it
