| Outline of Final Research Achievements |
Glaucoma is characterized by progressive visual field (VF) damage, which is irreversible, so it is important to predict VF progression in clinical use. In Humphrey Field Analyzer (HFA), which is commonly used in clinical settings, employs simple linear regression for analysis of VF data. However, it ignores the correlation between test points and so on.
We created a novel model for VF progression, and by means of learning the model using a lot of data we had, we were able to predict future VF more precisely than simple linear regression.
