How Glaucoma is Diagnosed
Glaucoma can be diagnosed with a combination of methods. Your vet will begin by testing the vision of your dog. After, measurements of the intra-ocular pressure will be taken, along with a detailed examination inside the eye and gonioscopy (a test that uses a special type of contact lens to look inside the eye in order to identify primary closed angle glaucoma). Ultrasound scanning of the eye could also be recommended if the vet is unable to see into the eye directly.
Is Glaucoma Reversible?
Oftentimes, glaucoma goes unnoticed as pets adapt very quickly to declining eyesight so the disease progresses past the point of treatment. If you are able to catch the symptoms of canine glaucoma, medications that can decrease fluid production and promote drainage can be prescribed to treat the increased pressure.
In more severe cases, surgery can be preformed by a veterinary ophthalmologist.
If the glaucoma has progressed to the point of blindness and your dog in extreme discomfort due to the increased pressure, the ophthalmologist may remove your dogs eye to remove the source of the pressure and pain.
