Glaucoma is a very painful condition, which leads to blindness due to an increased intraocular pressure if not treated early. Acute glaucoma is an emergency! Some dog breeds are predisposed to develop this disease due to an abnormality in their drainage angles. The conformation of the drainage angle of your dog can be easily evaluated by performing a gonioscopic examination. If your dog has glaucoma, a combined surgery may be recommended to maintain vision. A glaucoma shunt (silicone tube) is placed into the anterior chamber and underneath the adjacent conjunctiva to help fluid drain from the eye. The second procedure is laser therapy (cyclophotocoagulation) to destroy the tissue which produces aqueous humor.
