Eye help: Do retinal receptors, like rods and cones, grow back or is it that if you lose it, you lose it? - Help.com

Hello TravelerofWords. From as far as I know, glaucoma is caused by the “death” of retinal neurons, due to bad blood supply in tht area. I know glaucoma is not treatable, in the sense of reversing the process. BUT since there are 5 types of neurons in the retina… I don’t know about the photoreceptors part…

“Retinitis pigmentosa (RP) refers to a
heterogeneous group of hereditary eye
disorders characterized by progressive
vision loss due to a gradual degeneration
of photoreceptors.” I guess that is a “if you lose it, you lose it”

I’m sorry, it’s good I helped, but u make a confusion here. You see, the receptors u r talking about (rods and con) are neuron cells in themselves, not like the ends of the neurons, where the synaptic exchange takes place…
“The retina contains two types of photoreceptive cells —rods and cones—both
of which function to transduce light energy into action potentials.” (Fundametals of Human Neuropsychology). the rods and cons synapse with ganglionic cells, to convert the absortion of light based on chemical processes in electric action potential-signals … :)

don’t quite catch up with your words, still confused.
