Ahmed valve implantation to control intractable glaucoma after phacoemulsification and intraocular lens implantation in a dog.

An 11-year-old spayed female Miniature Poodle presented with bilateral senile cataracts. Treatment was cataract removal by phacoemulsification and intraocular lens implantation. Five hours after surgery the operated right eye was partially closed and painful. The right pupil was fully dilated, there was generalized corneal edema, and intraocular pressure (IOP) was increased. After 12 h of medication IOP was controlled. Ten weeks after surgery the owners reported cloudiness of right eye, and the dog was again evaluated. The IOP was again increased and an Ahmed valve was implanted. This case describes describe the progression of this case and benefits of controlling postcataract surgery glaucoma by the implantation of an Ahmed valve.
