“…Therefore, the veterinarian must help the owner to comprehend why his/her dog has developed a loss of vision (whether the blindness is complete or partial), if systemic signs of disease are present or systemic diseases have been previously diagnosed (because often several systemic diseases, such as infectious diseases, hypertension, etc., may initially be recognized by their ocular manifestations), and how to help the animal to adapt to ocular impairment. Furthermore, modern progress in veterinary ophthalmic surgery, such as cataract removal by phacoemulsification, retinal detachment surgery, and laser endoscopic cyclophotocoagulation, has increased the treatment options for the patients that previously would be permanently blind [ 9 , 10 , 11 , 12 ], thereby improving their life quality. Although many dogs with blindness diagnosis can live a good life [ 13 ], the owners require euthanasia of the animal but with a treatable and/or non-fatal condition (“convenience euthanasia”), either for financial reasons or simply because they do not want he/she anymore.…”
