Surgical Procedures for Glaucoma: What the General Practitioner Needs to Know

Glaucoma can be treated by medical and surgical options. Most ophthalmologists believe that patients with glaucoma are best treated with surgery. Early recognition of clinical signs and selection of the most effective type of surgery depending on the stage of glaucoma and the underlying cause are important factors in glaucoma surgery. Several surgical procedures exist for dogs with primary glaucoma, which may include a cyclodestructive technique or an aqueous outflow bypass procedure or a combination of both procedures. Salvage procedures such as enucleation, evisceration with an intrascleral prosthesis, or chemical intravitreal injection may be advised for chronically blind eyes with no hope of vision. Client compliance and expectations, therapeutic goals, status of vision (visual versus blind), financial constraints, surgical expertise, and underlying systemic disorders should be considered in the selection of the most appropriate surgical option for each patient.
