Question
What are the symptoms of optic nerve atrophy?
Answer
Optic nerve atrophy is a degenerative disease of the optic nerve caused by gliofibrous proliferation and circulatory disorders. It is a chronic progressive retinal disease, often seen in young adults. Clinical features include gradual vision loss, ultimately leading to blindness, with the optic disc appearing pale or even cyanotic, and the visual field showing concentric contraction or sectoral defects. In the early stages, there may be no conscious symptoms, but the condition may not be discovered until central vision and color perception (starting with red then green) are impaired.
