Cell death in photoreceptor cells is reversible, study finds‎

Photoreceptors are specialized cells in the eye that convert light energy into neural signals. Several diseases that cause irreversible vision loss, including age-related macular degeneration, retinitis pigmentosa and retinal detachment, are associated with dying photoreceptors. While there are many molecular pathways that result in cell death, there are also many that try to keep the cell alive.
