Boz, a six-year-old male Boston terrier adopted by Dr. Suzanne Marrs and her sister LuAnn, was experiencing some redness, pain, and mucoid discharge in his right eye when he first became a member of the Marrs family.
Their veterinarian, Dr. Susan Thrash, diagnosed Boz with dry eye disease and began medical therapy; however, after several months, Boz’s eye was still giving him a lot of trouble so Dr. Thrash referred him to the MSU CVM ophthalmology service.
During their monthly clinic at the AERC, Dr. Caroline Betbeze and her team evaluated Boz and made some changes to his medical therapy to try and improve his clinical signs with medications but were uncertain how successful the new regimen would be, because they determined that Boz was likely born with congenital alacrima (or the lack of tear ducts) in his right eye.
After three months on the new medications and little to no improvement in Boz’s eye, Dr. Betbeze met with the Marrs family to discuss performing a parotid duct transposition surgery which moves a salivary duct from another area in the body to the eye in order for it to deliver saliva onto the eye as a replacement for tears. The surgery is reserved for non-responsive cases, and since Boz still had good vision, he was a candidate in order to preserve his vision and remain comfortable.
In January 2023, Boz underwent the procedure. He came through surgery fine, healed well, and has responded very well. At his recheck appointment, Dr. Betbeze saw that Boz’s vision was still intact, his eye was comfortable, and he was producing a small amount of saliva throughout the day to keep the eye moist—a perfect outcome!
When dry eye disease is severe, it’s very painful and can lead to vision loss due to corneal scar tissue and pigmentation. Thanks to Dr. Betbeze and her team, that is not the case for Boz Marrs.
