ABSTRACT
Both the elderly and children can experience macular degeneration leading to significant vision loss. The cure for blindness may have been science fiction, when the sight-restoring visor worn by Star Trek’s character Geordi La Forge was replaced by ocular prosthetic implants. But gene therapy, stem cell therapy, and a genetically modified version of vitamin A are currently being researched as viable cures. And scientists have grown the precursor of the human eye in the laboratory (Cyranoski, 2012).
