Have early stage glaucoma. drops have stabilized pressure, no damage. is it okay to have optometrist monitor but have yearly visit w/ opthmologist?

Should be fine: That should be fine. Od's are capable of measuring pressures and can refer you back to your ophthalmologist sooner if anything suspicious.

Depends: It depends on the comfort level you have with this, but more importantly, it depends on the skill set the od has & the working & trusting relationship the od & glaucoma specialist have. If there is accurate & meaningful exchange of information regarding your eye function & your response to treatment & data collection is showing stable disease, i think co manage care may be okay. I don't prefer it.
