In monitoring open angle glaucoma, if oct test results taken 1 yr. Apart are different, can it mean glaucoma isn't stable? No change in visual field.

In brief: Open angle glaucoma

By definition will diminish your retinal nerve fiber layer (rnfl) over time if not well controlled.
Serial rnfl scans are highly sensitive and can detect small changes prior to a formal visual field test demonstrates changes. Questions if loss is occurring can be answered by looking at serial scans of the rnfl over time and looking for trends. So, yes, it may not be stable and requires follow up.

Also, ganglion cell layer analysis done at the same time adds even greater accuracy. BUT... Please make sure the quality of the tests are good and they are repeatable! A single test doesn't mean the world is ending!

Quality scanning is definitely key. Eventually statistical programs will be devised for serial scan analysis.

In brief: Good ?, difficult

Unfortunately it is still difficult to answer this question from a statistical progression analysis.
The whole picture of your disease has to be utilized to answer whether your glaucoma is controlled well enough. This includes iop stability/reduction, visual field stability (statistically analyzed over time), clinical optic nerve changes, and other health related factors. Genetics are a given.

I agree with Dr. Fishburn. Tests like OCT and HRT help to confirm if glaucoma is progressing, but typically shouldn't be used by themselves to change treatment if the other exam findings appear to be stable.
