Endoscopic Cyclophotocoagulation at MedVet

In 2006 when we were introduced to endoscopic cyclophotocoagulation (endolaser, ECP).  At the time it was Drs. Dineli Bras, Milt Wyman, and me comprising the MedVet ophthalmology team.  We were all intrigued, excited, and apprehensive all at once about the potential therapy this laser might provide.  There were studies in people and certain MD ophthalmologists well versed in its utility, but how could we transfer it over to our patients?  Dogs aren’t small humans after all, but we were up for the challenge.

In 2006, the first dog patient in the world underwent ECP at MedVet.  The procedure involves a small limbal incision where the surgeon ablates the ciliary processes using a 19-gauge probe equipped with a camera, diode laser, and light source (Video 1).

Retrospective evaluation of our cases has shown an approximate 80% success rate for vision at one year post-ECP.  Compared to medical therapy with primary glaucoma where the success rate for vision at one year is close to 0%, ECP has become the recommendation of most ophthalmologists when owners want to know they have done all they can to prolong vision.
