In the U.S. transcleral cyclophotocoagulation is a treatment of last
resort; it is by definition destructive, is somewhat unpredictable, and
is very difficult to titrate.  It is better than cyclocryotherapy but
is not my idea of a good time.  The laser is aimed by just knowing
where the ciliary body is in relation to the limbus.

A less accepted but growing procedure in endocyclophotocoagulation
which is done from the inside of the eye and directly targets the
ciliary processes; the cells that produce aqueous.  It does not have
the dramatic effect of transcleral but is also far less dangerous.  It
is usually done in combination with cataract surgery.

I do not know what you mean by follow up the cyclophotocoagulation in
real time.  It takes weeks to really tell what the effect will be.
