Idiopathic glaucoma in an 11-year-old crossbred mare
1Ontario Veterinary College, University of Guelph, 50 Stone Road East, Guelph, Ontario N1G 2W1.
Summary
A horse diagnosed with glaucoma experienced severe eye pressure and swelling. Despite initial treatment, the condition worsened, leading to the necessary surgical removal of the eye.
Area of Science:
- Veterinary Ophthalmology
- Equine Medicine
Background:
- Glaucoma is a significant cause of vision loss in horses.
- Early diagnosis and intervention are crucial for managing equine ocular conditions.
Observation:
- An 11-year-old mare presented with buphthalmia (enlarged eye), unresponsive pupil, and corneal edema.
- Intraocular pressure was critically elevated, exceeding 80 mmHg.
Findings:
- The clinical signs were consistent with advanced glaucoma.
- Despite medical management, the intraocular pressure remained uncontrolled.
Implications:
- This case highlights the aggressive nature of equine glaucoma.
- Enucleation may be the only viable option for advanced, unresponsive cases.

Glaucoma: Overview
1.5K
Glaucoma is an eye condition characterized by increased intraocular pressure that damages the retina and optic nerve, leading to irreversible blindness if left untreated. The human eye has various components, including the cornea, iris, pupil, lens, and optic nerve. Aqueous humor is secreted by the epithelium of the ciliary body in the posterior chamber and flows through the trabecular meshwork and canal of Schlemm, maintaining normal intraocular pressure. The trabecular meshwork and the canal...

Open Angle Glaucoma: Treatment
1.1K
In open-angle glaucoma, the iridocorneal angle remains open, but the trabecular meshwork becomes stiff, slowing down the outflow of aqueous humor. This causes a buildup of aqueous humor in the anterior chamber, leading to a sudden increase in intraocular pressure. The treatment for open-angle glaucoma focuses on reducing the elevated intraocular pressure by either decreasing the secretion of aqueous humor or increasing its outflow.

Angle Closure Glaucoma: Treatment
1.4K
Angle-closure glaucoma, or closed-angle glaucoma, is an eye condition where the iris bulges out and blocks the iridocorneal angle, resulting in a buildup of aqueous humor and increased intraocular pressure. Immediate medical attention is necessary due to the sudden onset of symptoms. The treatment for angle-closure glaucoma includes short-term and long-term approaches. Short-term treatment involves using eye drops like pilocarpine to lower intraocular pressure by increasing aqueous humor...
