Gene Therapy Without Retinal Risk

Researchers have developed a method of delivering genes to the inner layers of the retina without the risks associated with injection into the delicate tissues themselves. This less invasive technique has been carried out successfully in animal models by a research team led by Drs. John G. Flannery and David V. Schaffer at the University [Read More]

Gene Expression in the Retina Expanded

Identifying the genetics of retinal degeneration has become especially important with progress of trials in gene therapy. Investigators have identified more than 200 retinal degeneration disease genes, but still haven’t been able to find the cause of disease in up to half of cases. Now Ocular Genomics Institute has announced that Drs. Michael Farkas, Eric [Read More]

Visual Field Grid

The Visual Field Grid was designed to allow you to map the scotomas (blind spots) in your central vision. It is easy to do, and it can be used to either monitor your own own progress or to explain your vision to others. To map your visual field, print this page and follow the steps [Read More]

Snellen Chart

This is the same chart that your doctor uses to determine your visual acuity. The normal height for the letter A is 88 mm, and the viewing distance is 6 meters. To properly view the chart on your monitor: Measure the height of the letter A in millimeters Divide by 88 Multiply by 6 The [Read More]
