A member asked:

Can you tell me: are visual field defects always present in glaucoma?

A doctor has provided 1 answer

Frequently: Changes in the field of vision are one of the hallmarks of the diagnosis of glaucoma. The aim of treatment is to prevent this from happening and also to prevent it when present from progressing. Some cases are detected early when other changes hint strongly that glaucoma could be a problem, and so field defects might not have occurred yet in such cases.
