Pigs Used to Cure Blindness

May 24, 2016

In July, an artificial bioengineered cornea that Chinese scientists spent more than 10 years developing will go into mass production. The corneas come from the eyes of pigs. Doctors say this will help close the gap between 4 million  blind patients and 5,000 donors.


Medical workers implant a pig-derived cornea into a patient’s eye in a hospital in Wuhan, Central China’s Hubei Province.

 Topics include:

  • Description and use of low vision aids
  • Electronic technology for low vision
  • Eyeglass technology
  • Optical and non-optical aids
  • Adaptive techniques
  • Types of vision loss and the impact on vision
  • Clinical Reasearch
  • Resources

Skin-to-Eye cell transplant partially restores AMD patient’s vision

May 7, 2016

This article by Lauren Tappan:

Japanese scientists have successfully completed the first skin-to-eye stem cell transplant in humans. The procedure managed to partially restore the vision of an elderly woman suffering from age-related macular degeneration (AMD).

The results of the procedure, which took place in 2014, were shared at the 2016 conference of the Association for Research in Vision and Ophthalmology in Seattle earlier this week.

Scientists took a small 4 millimeter (.15 inch) piece of the patient’s skin from her arm and modified its cells, effectively reprogramming them into induced pluripotent stem cells (iPSC), Science Alert reported.

Because pluripotent stem cells have the capability to differentiate into almost any type of tissue within the body, the skin cells taken from the arm could be repurposed into retinal tissue.

From there, the cells were developed into retinal pigment epithelium (RPE) and cultured in the lab to grow into an ultra-thin sheet. This sheet was then transplanted behind the retina of the patient.

Device on Eyeglasses Helps Low Vision Readers

May 7, 2016

A miniature camera using optical character-recognition technology, mounted onto the eyeglasses of people who are considered legally blind, dramatically improves their ability to read an email, newspaper article, menu or page in a book, a study by researchers with UC Davis Health System has found.


Using the the study participants were significantly better able to perform activities of daily living. The device recognizes text and reads it to the user using an earpiece that transmits sound, and can also be programmed to recognize faces and commercial products.
