 What is ankyloblepharon? | adhesion on eyelid margins, occurs normallys from 10-14 days of life in dogs and cats. |
| What can be done for pups with ankyloblepharon after 15 days of life? | gentle traction on eyelids or blunt dissection |
| What is ophthalmia neonatorum? | infection behind the eyelids in newborns |
| In what species is eyelid agenesis more common? | cats and horses |
| What are some options to repair a small defect associated with eyelid agenesis? | -cryosurgery and ocular lubricants -simple wedge resection |
| Does micropalpebral fissure generally need surgical intervention? What about macropalpebral fissure? | No Yes- may need surgical treatment |
| What are the indications for surgical shortening of the eyelids for patients with macropalpebral fissure? | if there is pigmentation, exposure keratitis, or recurrent corneal ulcers |
| (entropion/ectropion) is the inversion of the eyelid margin whereas (entropion/ectropion) is the eversion of the eyelid margin. Entropion is a bigger concern/problem. | Entropion, ectropion |
| What are corneal sequelae to entropion? | -ulceration -vascularization -pigmentation -corneal scarring |
| What causes spastic entropion? | lid spasm associated with pain (from FB, ulcer, etc) that causes eyelid to fold in |
| Is it preferred to perform surgical repair in young animals with anatomic entropion? | no, use temporary treatments until animals are mature and then reassess |
| When performing a Hotz-Celsus procedure for entropion, should the incision be closer to the eyelid margin or away from the eyelid margin? | close to the eyelid margin. If it is too far away, then will not do anything to help pull the eyelid out. |
| How to determine how much skin to take for entropion repair? How would you assess the animal? | -apply topical anesthetic to relieve spasms -assess conformation in a conscious, unsedate animal |
| What treatment would be best for ectropion? A. wedge resection B. Hotz-Celsus C. Eyelid tacking D. Medial canthoplasty | A |
| Is it important to get the eyelid margins to oppose perfectly when performing wedge resection techniques, or will the tissues heal well regardless? | it is important to get the eyelid margin to oppose perfectly to heal well without gapping/scarring |
| Match the terms with their meaning: 1. trichiasis, 2. districhiasis, 3. ectopic cilia A-hairs emerge from meibomian gland openings B-hairs emerge through the palpebral conjunctiva C-normal facial hairs that contact the cornea/conjunctiva | 1-C 2-A 3-B |
| Which of the below are more likely to cause problems? A. trichiasis B. distichiasis C. ectopic cilia | C |
| What is the most common treatment method for distichiasis that is causing problems in their patients? | cryosurgery |
| Is ectopic cilia more common in older or younger patients? | younger |
| What is the term used to describe the infection of eyelid glands? | hordeolum (stye) |
| What is Chalazion? | granuloma fomation from insipissated meibomian gland secretions |
| When a patient has blepharitis, or inflammation of the eyelids, what should be the first thing you think? | Demodex! |
| What are some other causes of Blepharitis? | -bacterial- staph -mycotic-Microsporum or Trichophyton -immune mediated - allergies, pemphigus, uveodermatologic syndrome -traumatic- lye, acids, fire -actinic- sunlight related |
| What is another name for Juvenile Pyoderma/Cellulitis? | puppy strangles |
| What are some treatment options for puppy strangles? | topical and systemic broad spectrum antibiotics, systemic corticosteroids |
| When it comes to treating Blepharitis, are systemic or topical medications generally more efficaceous? | systemic |
| What are some consequences of poor lid margin apposition? | -trichiasis -exposure keratitis -marginal scar tissue can abrade cornea |
| In the canine patient, eyelid tumors tend to be (benign/malignant). Eyelid tumors in cats to tend to be (benign/malignant). | benign, malignant |
| In dogs, what is the most of the eyelid length that you might be able to take to remove eyelid tumor? | 30% (would not be possible in cats!) |
