Current Genetic Eye Disease Research on Fuch’s, Leber’s and Retinitis Pigmentosa

Current research on genetic eye diseases focuses mostly on genetic therapies. Scientists have learned how to sequence DNA at a relatively low cost. New tools for modifying genetic materials, such as the CRISPR, have opened the door for new treatments and even cures. Certain eye disorders are caused by mutated genes and genetic predispositions. This … Continue reading “Current Genetic Eye Disease Research on Fuch’s, Leber’s and Retinitis Pigmentosa”

Leber Congenital Amaurosis Gene Therapy Approved by FDA

The rare eye disease Leber Congenital Amaurosis, caused by a defective gene, has a new genetic treatment. This is the first time the US Food and Drug Administration has approved gene therapy for an inherited disease. The RPE65 gene provides a blueprint for a protein that makes light receptors work properly. Individuals with a defective … Continue reading “Leber Congenital Amaurosis Gene Therapy Approved by FDA”

Gene Therapy for Leber’s Disease

In 2009, Dr. Jean Bennett and his team from Albert Maguire of the University of Pennsylvania School of Medicine injected a benign virus carrying a connected copy of an essential gene into a teenage boy’s retina. This patient had lost vision due to a genetic disorder called “Leber’s Congenital Amaurosis (LGA). The result was improved … Continue reading “Gene Therapy for Leber’s Disease”

Leber’s Disease – Gene therapy transforms eyesight

Pennsylvania researchers using gene therapy have made significant improvements in vision in 12 patients with a rare inherited visual defect, a finding that suggests it may be possible to produce similar improvements in a much larger number of patients with retinitis pigmentosa and macular degeneration.

Research on Reversing Color Blindness

Approximately eight per cent of men and one-half of one per cent of women in the U.S. have a problem with their color perception. Most colorblind people have lost only part of their color vision. Usually, only one or two types of cones are either absent or not functioning normally. If the dysfunction is in … Continue reading “Research on Reversing Color Blindness”

Mitochondria: Essential Powerhouse for Brain & Vision

Why are mitochondria essential to your health and well-being? Mitochondria are the energy batteries of our cells. They are tiny organelles within most cells of the body that provide respiration and energy. Low metabolism develops in the brain as we age and is noticeable in brain regions where mitochondrial structure has changed. 1 The mitochondria … Continue reading “Mitochondria: Essential Powerhouse for Brain & Vision”

Retinitis Pigmentosa Gene Editing Studied on Human Embryos

The genetic eye disease Retinitis Pigmentosa is the target of gene editing research on human embryos by Dr. Dietrich Elgi at Columbia University. National Public Radio reported on this research1 shortly after a Chinese scientist announced he had created the world’s first two gene-edited babies.2 Both scientists use the CRISPR tool to genetically modify human … Continue reading “Retinitis Pigmentosa Gene Editing Studied on Human Embryos”

Which Parts of the Eyes Are Associated with Which Eye Diseases?

The eyes are small, but they have many parts including the eyelids, sclera, cornea, lens, optic nerve and retina. We depend heavily on our vision. When something goes wrong, the eyes are disproportionately affected. For example, a senior at risk of heart disease is also at risk of an ocular arterial or vein occlusion. Also, … Continue reading “Which Parts of the Eyes Are Associated with Which Eye Diseases?”

Rod-Cone Dystrophy – A Complete Overview by Natural Eye Care

Rod-Cone Dystrophy is a genetically-based deterioration of vision caused by damage to the photoreceptors in the eye. Rods and cones are the photoreceptor cells in the retina that give us daytime and night time vision. Genes that provide the blueprint for manufacturing proteins crucial to the eye’s rods and cones are damaged. Without enough of … Continue reading “Rod-Cone Dystrophy – A Complete Overview by Natural Eye Care”

What is Optic Nerve Atrophy?

Optic nerve atrophy, also called optic neuropathy, is damage to the optic nerve from any cause. Some of these causes include: diabetes, glaucoma, certain health problems associated with aging, brain tumors, head trauma, infection, multiple sclerosis, radiation, inflammatory blood vessel diseases, sleep apnea, excessive blood coagulation, high cholesterol, genetic disorders, poisoning, malnutrition, and drug side … Continue reading “What is Optic Nerve Atrophy?”
