Explanation:
Detailed explanation-1: -Treatments. At this time there is no treatment available for Stargardt disease. However, researchers are studying gene and drug therapies. One promising study involves delivering a healthy version of the gene that causes Stargardt disease, ABCA4, into retinal cells to restore production of the normal protein.
Detailed explanation-2: -There’s no treatment for Stargardt disease, but vision rehabilitation can help people make the most of their remaining vision.
