Can some eye conditions be explained by a problem in a given spine vertebra? We know that the spine is connected to the nervous system, I already saw some charts connecting each vertebra to an organ and the C-2 was defined for eyes and optic nerves.
I'm not entirely certain what you mean by "spine misalignment", but there are certainly traumatic injuries to the cervical neck that can indirectly result in full or partial blindness. This would usually occur due to neurovascular compromise. Cervical artery dissections with subsequent cerebral infarction and homonymous hemianopia are a classic cause of visual loss after trauma.
For further reading on post-traumatic visual loss, I would refer you to this review article.
No, not that I'm aware. You might see this referred to in Chiropractic charts but chiropractic is an alternative non-science based system.
Chiropractic is a form of alternative medicine mostly concerned with the diagnosis and treatment of mechanical disorders of the musculoskeletal system, especially the spine. Proponents claim that such disorders affect general health via the nervous system. These claims are not backed by any evidence.
