Conjunctival Disorders Flashcards
Pinguecula and Pterygium are
benign growth of the conjunctiva that can result from chronic actinic irritation
Raised yellowish white mass within the bulbar conjunctiva adjacent to cornea - does not tend to grow into cornea
Pinguecula
Treatment of Pinguecula
rarely necessary, can be easily removed (ophtho)
Fleshy triangular growth of bulbar conjunctiva that may spread across and distort cornea, induce astigmatism, change refractive power of eye
Pterygium
Treatment of Pterygium
Symptomatic relief: artificial tears or short treatment with corticosteroid drops or ointments
removal indicated for documented growth, cosmetic concerns, to reduce irritation, to improve or preserve vision (ophtho)
most common cause of cause of eye redness, refers to inflammation or infection of conjunctiva
conjunctivitis
types of conjunctivitis
viral (children), bacterial (adults)
Infectious conjunctivitis “pink eye” - viral presentation
children more than adults
most cases highly contagious for 10-14 days
FB sensation, red eyes, itching, light sensitivity, burning, watery discharge
Treatment of viral conjunctivitis
sx relief: artificial tears, cool compress
resolution can take up to 3 wks - most 14 days
preventing spread
topical steroids, topical antiviral
Bacterial conjunctivitis presentation
redness, tearing, discharge from one/both eyes (glued eyes)
pain, vision loss, photophobia, no itch or burn
bacterial conjunctivitis treatment
resolve within one wk
topical abx
duration of treatment usually 5-7 days
Pts with contact lenses are more susceptible to ________ bacteria
gram negative
Pts with contact lenses are more susceptible to ________ bacteria
gram negative
Pts with contact lenses are more susceptible to ________ bacteria
gram negative
Inflammatory process involving both conjunctiva and superficial cornea - usually occur in association with viral, bacteral, autoimmune, toxic, allergic etiologies
keratoconjunctivitis
Viral Keratoconjunctivitis presentation
eye discomfort/ irritation
pruritus
light sensitivity
minor blurring
conjunctival injection, conjunctival chemosis, eye discharge
Viral Keratoconjunctivitis treatment
no effective treatment exists
artificial tears, cool compresses, topical antihistamines
Keratoconjunctivitis sicca treatment
sx relief - artificial tears, warm compresses, lid scrubs, oral flaxseed oil and fish oil supplements
meds - topical abx/ steroids, PO antihistamines
Procedural treatment
chronic, intermittent, bilateral burning, stinging, foreign body sensation, photophobia, eye fatigue, heavy eyelids, pruritus, epiphora, watery discharge, blurred vision, decreased tear production
Keratoconjunctivitis sicca - aka dry eye syndrome (DES)
Allergic conjunctivitis presentation
frequently accompanies seasonal allergy symptoms, specifically known allergy exposures or history of atopy
itchiness, diffuse conjunctival injection are the most common symptoms and presents in all types
Allergic conjunctivitis treatment
pt ed - eye care, rubbing eyes, avoidance of allergen, remove contact lenses
artificial tears and cool compresses
