Yes, the units are mmHg, his pressure is very high and likely he has
chronic angle closure glaucoma which is treated by surgery.

Not "routine", but if the other eye has a narrow or closable angle
which can be determined during examination, then that eye is at risk
of having the same thing happen. It is common for the other eye to
have a closable angle if one eye has already closed. The surgery is
prophylactic and will prevent a similar problem.
With acute angle closure the patient has pain and blurred vision which
drives them to the eye doctor and to treatment. With a slowly
developing chronic angle closure, there is little pain and often
little blur so the optic nerve may suffer considerable irreversible
damage resulting in permanent vision loss. The prophylactic treatment
carries little risk.

Thanks so much for a clear, concise explanation. It helps
tremendously, as did the refs you provided.
Have a great Thanksgiving if you're in the US, and a great weekend in
any case!
