Repurposed Drugs Restore Sight
Drug repurposing involves identifying new therapeutic uses for existing drugs. Examples include: Aspirin—Originally created as a pain killer, it was later found to be effective in preventing heart attacks and strokes. Thalidomide—Developed to treat morning sickness, it was later used as a treatment for multiple myeloma. Metformin—Initially an anti-diabetic drug, it was reworked as a […]

Unveiling the Secrets of Vision: Insights into Photoreceptors and Future Treatments
The photoreceptors in the eye are responsible for vision. There are two types of photoreceptors: rods and cones. Rods are responsible for vision in low level light and they have little to do with color vision. Cones function in bright light and are vital for color vision. Vision loss occurs when the photoreceptors aren’t working. […]
Night Vision Tests and AI Part One
The two forms of age-related macular degeneration progress at different rates. The wet form of the disease progresses faster than the dry form. Still regardless of the type, once someone is diagnosed with age-related macular degeneration, that person can expect a decline in vision to take place gradually over the course of five years. In […]
Light and Dark
While it is difficult to do near work like reading, writing or certain crafts like needlepoint, in low light, for the most part our eyes adjust and we can maneuver in the space or at least find the light switch. How does our eyes and brain work so that we can see both in low […]
Detecting & Fixing Eye Diseases
In eye diseases like retinitis pigmentosa, age-related macular degeneration and Leber congenital amaurosis, things are going on in the cellular level that occur before anything is detected by way of a test or observation. It would be great if these changes could be detected sooner and if there was a way to stop the deterioration […]
Stopping Degeneration in its Tracks Part One
Retinitis pigmentosa is a group of rare genetic disorders that leads to the loss of retina cells. Symptoms include difficulty seeing at night or in low light conditions and the loss of peripheral vision. Age-related macular degeneration is a disease that blurs the central vision that you need for reading and driving. Both disorders are […]
