Equine glaucoma.

This research examines the disease of equine glaucoma, a severe neurodegenerative ocular condition in horses causing blindness, predominantly found as a secondary condition to uveitis. The study discusses diagnostic strategies and therapy options but identifies that current prognosis for equine vision remains poor.

Understanding Equine Glaucoma

• Despite the in-depth knowledge of human glaucoma, our understanding of equine glaucoma remains underdeveloped. This disease is characterized by the progressive loss of retinal ganglion cells and their axons that form the optic nerve and eventually cause blindness.
• The disease is complex, driven by multiple factors and develops most commonly alongside uveitis. This piece points to the possibility that equine glaucoma may be frequently underdiagnosed or misdiagnosed in horses with uveitis.
• Increased awareness amongst clinicians, coupled with portable tonometers, or pressure meters, is improving diagnosis accuracy.

Treatment of Equine Glaucoma

• The focus of therapy for equine glaucoma is managing and reducing the production of aqueous humor – the clear fluid in the front of the eye, between the cornea and the lens. This relief strategy can be achieved via both medical and surgical methods.
• Despite these interventions, the research outlines that the long-term vision prognosis for horses suffering from glaucoma remains poor. Therefore, it underlines an urgent need for improved understanding, diagnostic methods and treatments for equine glaucoma.
