H47: Other disorders of optic [2nd] nerve and visual pathways

The ICD-10 H47 pertains to a group of disorders known as 'Other disorders of optic [2nd] nerve and visual pathways,' which affect the nerves that transmit visual information from the eye to the brain. Various conditions fall under this classification; each stems from damage to the optic nerve due to different causes like inflammation, compression, or inherited disorders. Typical symptoms can vary but often include blurry or decreased vision, different coloured vision in each eye or loss of colour perception, and sometimes pain when moving the eye. The progression of these disorders can range from slow and gradual to swift and sudden, generally causing irreversible vision loss. The system primarily affected by these disorders is the nervous system, particularly the visual subsystem.
