Feline/Equine Glaucomas
How does it work??
100
This is the normal range of IOP in a cat or dog.
What is 15-25 mmHg?
100
Glaucoma is a result of (increased/decreased) (production/drainage).
What is decreased drainage?
100
In acute glaucoma, these drugs may be used to bring down the intraocular pressure.
What is Xalatan or Travatan or IV mannitol or PO glycerin?
100
Of primary and secondary glaucomas, this is the most common in cats.
What is secondary glaucoma?
100
This is how the Tonopen works.
What is it measures force used to depress a metal plate?
200
When measuring IOP with a tonometer, this must not be occluded during the restraint?
What are the jugular veins?
200
When considering glaucoma in an animal, this distinction must be made as to its cause.
What is a primary vs secondary cause?
200
Cosopt is a combination of these two drug types.
What are beta blockers and carbonic anhydrase inhibitors?
200
This is the most common cause of glaucoma in horses.
What is ERU (moonblindness)?
200
This is how the Tonovet works.
What is measures speed at which probe bounces back into machine?
300
This technique is used to look for a closed iridocorneal angle.
What is gonioscopy?
300
This is the most common cause of glaucomas in dogs (primary/secondary).
What are secondary glaucomas?
300
What oral medication can we place animals on to lower their IOP?
What is methazolamide?
300
Horses are fairly resistent to developing glaucoma due to this.
What is greater uveoscleral outflow?
300
This is what carbonic anhydrase dose.
What is catalyze formation of carbonic acid from CO2 and H2O?
400
What signs are noted in the retina on fundic exam in an eye with chronic glaucoma?
What are tapetal hyperreflectivity and optic nerve cupping?
400
This condition in the iridocorneal angle is associated with glaucoma in certain breeds.
What is goniodysgenesis?
400
Latanoprost/Travaprost are part of this class of drug. This side effect in the pupil is observed as a result. (2 parts)
What are prostaglandin analogs? What is a pinpoint/miotic pupi?
400
Cats develop a condition called "malignant glaucoma" that is characterized by this.
What is aqueous misdirection?
400
Lasers do this to reduce IOP.
What is destroy ciliary body epithelium that produces aqueous humor?
500
These are 5 signs that you can see on your
ophthalmic exam in an eye with glaucoma (without a fundic exam).
Vision: Blind
Globe: Buphthalmos
Episclera: Episcleral injection
Cornea: Edema, Corneal striae
Iris: Fixed and dilated pupil
Lens: Aphakic crescent/Lens subluxation
500
In uveitis, secondary glaucoma can result because of these two processes.
What is pupillary block or obstruction of the iridocorneal angle?
500
These two indications are guidelines to enucleate or eviscerate an eye.
What are blindness and discomfort?
500
This drug is not utilized in cats when treating glaucoma due to decreased efficacy.
What are prostaglandin analogs?
500
This is the main way prostaglandin analogs help decrease pressure.
What is increase uveoscleral outflow?
