Visual Field Staging
Question: When do we assign a stage to glaucoma: only upon visual field performance?
Answer: Yes. You use the visual field to determine staging. The last page of the Glaucoma Quick Reference Guide includes this language:
Indeterminate stage ICD-10 7th digit “4”:
- Visual fields not performed yet;
- Patient incapable of visual field testing;
- Unreliable/uninterpretable visual field testing.
