A vitamin A discovery is changing what scientists know about vision
Johns Hopkins researchers have discovered how a vitamin A-derived molecule interacts with thyroid hormones to form sharp central vision in the human retina. This breakthrough could lead to new treatments for degenerative eye diseases like macular degeneration.
Scientists at Johns Hopkins University have uncovered how humans develop sharp central vision before birth, identifying a carefully timed interaction between a vitamin A derived molecule and thyroid hormones in the retina. The discovery challenges a decades old explanation for how key light sensing cells form and could guide future treatments for macular degeneration, glaucoma, and other diseases that damage vision.
