QUESTIONS WITH VERIFIED SOLUTIONS
PRACTICE SET
●● hordeolum
Answer: - commonly d/t staph
- internal (meibomian gland)
- external (Zeis gland, STYE)
- tx: warm compress, incision if no improvement, abx ointment (baci or
erythro) during acute stage
●● chalazion
Answer: - infection or retention cyst of a meibomian gland, showing as a
beady nodule on the eyelid
- tx: warm compress; incision if no improvement in 2-3wk
●● blepharitis
Answer: inflammation of the glands and eyelash follicles along the
margin of the eyelids
- s/s: irritation, burning, itching
- posterior: meibomian gland, lad rolled inward (entropion),
telangiectaias
- anterior - red rimmed, scales or colleretts
,- tx: warm compress, baby shampoo scrubs, baci/erythro in acute stages
●● endotropion
Answer: - Inversion of the lid and lashed caused by muscle spasm of the
eyelid. Friction from lashes can caused corneal irritation.
- usually lower lid
- common with age increase
- sx if lashes cause irritation
- botox temporary fix
●● Ectotropion
Answer: outward turning of the eyelid
●● basal cell carcinoma
Answer: most common malignant tumor of eye lid
●● dacryocystitis
Answer: - inflammation, infection of lacrimal sac
- usually UL
- s/s: tearing, d/c, pain, erythema
- patho: strep, staph epi
- tx: acute w/ sys abx or sx to resolve obstruction; congenital usually
resolves spont
,●● Viral conjunctivitis
Answer: adenovirus; highly contagious**
swimming pools - epidemic keratoconjunctivitis
- lg pre-auricular lymph nodes (not present in bacterial)
*erythema, copious watery discharge
tx: supportive
- if d/t herpes then need antivirals (usually UL)
●● Bacterial conjunctivitis
Answer: - pink eye
- staph, strep, moraxella, psuedomaonas
- s/s: purulent d/c and matting, mild vision blurring
- usually self-limiting (10-14d)
●● Chlamydial conjunctivitis
Answer: Trachoma - Most common cause of blindness worldwide due to
chronic scarring.
●● Vernal Keratoconjunctivitis
Answer: - conjunctivitis in late childhood, early adulthood
, - seasonal
- cobblestone papillae, trantas dots (yellow-white points in limbus) and
horner points (in conjunctiva), long eyelashes, dennie lines
- corneal involvement in severe cases
- affects more men than women
●● Atopic Keratoconjunctivitis (AKC)
Answer: -bilateral inflammation of conj and eyelids
- usually with atopic dermatitis (eczema) and erythema
- rarely seen before late teens
- ocular s/s worse and all year
- vision impairment d/t corneal damage
●● Pinguecula
Answer: - yellowish mass on the conjunctiva
- common in >35 yo
- usually BL and on nasal side
- rarely grow
●● pterygium
Answer: - fleshy, triangular encroachment of conjunctiva onto cornea
- usually caused from sun, wind exposure
