Ocular Allergy Flashcards
What diseases can follicles be found?
Viral
Toxic
Chlamydial Disease
Compare the vasculature of follicles to papillae.
Papillae are tissues masses w/ a central vessel tuft while follicles have a central avascular zone
What diseases do papillae occur in?
Allergic
Bacteria
Chlamydial
Compare the origin of papillae to follicles.
Papillae are a focal infiltration of inflammatory cells while follicles are expansions of the lymph system.
What part of the conjunctiva do papillae and follicles occur?
Papillae occur on the upper and lower palpebral conjunctiva while follicles occur on the inferior palpebral conjunctiva
Follicles also are usually accompanied by preauricular adenopathy.
Bacterial conjunctivitis with diffuse papillary hypertrophy response
What is a good non-medication way to treat seasonal/perennial allergic conjunctivitis?
Lubricants and cold compresses
What is a vasoconstrictor you can use to treat allergic conjunctivitis and what should you take caution with while using it?
Naphcon
Be cautious of rebound
Name some mast cell stabilizers to use while treating allergic conjunctivitis.
Pemirolast (Alamast)
Nedocromil (Alocril)
Iodoxamide (Alomide)
Cromolyn sodium (Crolom)
Name some antihistamines that can be used to treat allergic conjunctivitis.
Emedastine (Emadine)
Levocabastine (Livostin)
What NSAID should you use to treat allergic conjunctivitis?
Keratolac (Acular)
Name some steroids you should use for allergic conjunctivitis patients?
Lotoprednol (lotemax, alrex)
Prednisone (Forte 1%, pred mild 0.25%)
How much of the general population has Eczematous dermatitis and what specific groups is greatest?
5-20%
Greatest in pediatrics
What should you use in your ocular allergy patients with rhinitis?
Oral antihistamines
What percent of atopic disease patients have atopic keratoconjunctivitis?
25-45%
AKC
What are the signs and symptoms of AKC?
Chemosis
Hyperemia
Papillary hypertrophy
Scarring
Itching, Tearing, Irritation
Stringy Mucous Discharge
Lids Sticking in AM
Eyelid issues
Chronic throughout the year
What are the eyelid issues associated with keratoconjunctivitis?
Flaking, scaling dermatitis, excoriated lesions
Madarosis
Periorbital hyperpigmentation
Thickening of margins
What are some ways to treat AKC?
Eliminate environmental antigens
Treat blepharitis w/ lid scrubs, warm compresses and massage w/ antibiotic ung and cool compresses for itch
Restasis
Ocular lubricants
Topical steroid to lids
How is VKC different from AKC?
Presents at younger ages
Burns out by late puberty
Less sight threatening
Spares the skin and eyelid margins
GPC on upper tarsus
Cornea Horner-Trantas dots at limbus
Giant (cobblestone) papillae
VKC Limbal Papillae
Gelatinous eosinophilic infiltrates in VKC
What disease are these found in?
VKC
