possible infectious agents leading to Blepharitis?bact, fungal, parasitic
two manjoy immune mediate causes of blepharitis (and examples of each)(1) allergic (such as to food or medication) (2) Vesicularbullous diseases (pemphigus!)
4 examples of things that can cause blepharitis which are not infectious or auto-immune?Solar, Drug reaction, foreign body, self-trauma
Granulomatous Blepharitis--> Chalazion--> what is this?Retained meibomian secretions. leads to Surrounding inflammation
Granulomatous Blepharitis-->Multifocal Granulomas--> what usually causes this problem?Infection of meibomian glands, aka Hordeolum
what is Hordeolum?multifocal granulomatous blepharitis
how do you treat Granulomatous Blepharitis?(could be Chalazion or Hordeolum) Surgical excision and curettage, Cryotherapy (+/-), Warm compresses, Topical antibiotics, Systemic antibiotics, steroids (+/-)
eyelid tumors more common in young or old animals?older animals
Biological behavior of eyelid neoplasia varies with species. How does the neoplasia behavior vary between dog, cat, and large animal?DOG: most commonly benign adenomas (dogs most favorable prog). CAT: tend to be invasive carcinomas. LARGE ANI: carcinomas common
dog: usually which neoplasia of the eyelid?Benign adenomas
cat: usually which neoplasia of the eyelid?Squamous cell carcinomas
horse: usually which neoplasia of the eyelid?Squamous cell carcinomas or sarcoids
cattle: usually which neoplasia of the eyelid?Squamous cell carcinomas (cancer eye)
how would you tx eyelid Adenomas?Debulk & Cryo, wedge resection
**when treating neoplasia of eyelid, never forget to...send for histopath!!!
how would you tx eyelid Carcinomas/Sarcoids?Resection & Reconstruction, Hyperthermia, Immunotherapy, Laser, Radiation, Combination Therapy
what agents do you use in Eyelid cryosurgery? what do you do/ what should you anticipate?Liquid nitrogen or nitrous oxide. Debulk lesion, Double freeze-thaw. Anticipate swelling and transient depigmentation
how to do Eyelid Tumors: Wedge excision (pic)
what is an option for Treatment of Equine Periocular SCC?Local Photodynamic therapy
(mentioned in class) 3 most common places for horse SCC eye tumors?eyelid margin, 3rd eyelid margin, temporal limbus (junction of corneal with sclera)

Slides 51-68 are additional cases and such which im not sure if she would test on... read over: just a few notes here. REFERRAL SHIT

Question Answer
refer when there is...primary repair (Greater than 1/3 margin affected, Large eyelid lacerations, Eyelid tumor resection), complex repair (Extensive entropion, Extensive ectropion, Entropion/Ectropion, Feline entropion)
why refer feline entropion?VERY thin eyelids compared to dogs, Specialized instrumentation, Overcorrect very slightly (various procedures)
refer with Hotz-Celsus with Arrowhead Modification. Technique Used withcomplex entropion, Entropion involving lateral canthus
H pasty is used for?repairing eyelid defect (like a mass)
refer is Hotz-Celsus and Wedge Resection. this technique used for...Complex entropion with euryblepharon, Combined ectropion/entropion
refer when Wedge Resection with Skin Flap...used for?Complex ectropion
(refer if) what is Stades Forced Granulation Procedure used for?Upper eyelid trichiasis-entropion with redundant facial skin
treat Upper eyelid entropion/trichiasis with?stades forced granulation procedure (includes Cilia/skin removal)
Upper eyelid entropion/trichiasis--> Excessive facial skin folds in Chow Chows--> do what about this?Orbital-frontal skin fold excision
Upper eyelid entropion/ can do a facelift!
Lateral canthal entropion is treated with?Arrowhead procedure with anchor suture
Lateral canthal entropion can be tx with..Lateral canthal tendonotomy
