This will require a period of hospitalization. Topically applied prostaglandins, such as lantaprost, also have been used in humans to reduce intraocular pressure. Yet more medications, known as carbonic anhydrase inhibitors, are aimed at reducing the production of aqueous humor. Once the pressure has been controlled, surgery is essential to maintain vision. A variety of surgical techniques have been developed to aid in the control glaucoma.
Laser surgery is the treatment of choice in pets with primary glaucoma who can still see.
As with the freezing procedure listed below, no cutting is required. The laser burns completely through the white outer layer of the eye without damaging it except for redness and swelling. The laser selectively kills small areas of the ciliary body and this reduces fluid production. The main complication of this technique is that it is like the Marshall of an old west movie who is shooting through the wall of a building to try to kill the villain. He can't see the villain and similarly the Doctor cannot see the ciliary body.
