Thin retina is not optic nerve atrophy and the two are not equivalent. Retinal thinning is a common condition, mostly due to high myopia, resulting in a simple thinning of the retina, which does not require special treatment. If the blood vessels in the eye are scarred, atrophy should be considered. Optic nerve atrophy is associated with a number of diseases that can cause lesions of the retinal ganglion cells and their axons. Simple retinal thinning usually does not require special treatment, but if there is retinal atrophy, the patient needs to go to the hospital in time to do the relevant treatment, according to the severity of the atrophy and the cause of the treatment.
