Glaucoma causes dangerously elevated eye pressure in dogs, leading to pain and rapid vision loss if not treated promptly and managed long-term.
Glaucoma causes severe pain that is often underestimated by owners who may not recognize the behavioral signs in dogs. The pain of elevated intraocular pressure is intense, comparable to severe headache in humans, yet affected dogs often only show subtle signs like reduced activity or hiding. Acute crises demand emergency treatment to save remaining vision and relieve pain. Chronic glaucoma requires daily medication and regular monitoring, and the disease frequently progresses despite treatment. Many dogs eventually require enucleation, which, while appearing distressing, reliably eliminates pain and allows affected dogs to resume comfortable lives. Early recognition and prompt treatment are the most important factors in minimizing suffering.
