110
Q

What condition is an acute localized infection or inflammation of the eyelid margin involving sebaceous gland? It involves Straphylococcus aureus in 90-95% of cases and is most common in kids.

A

Hordeolum (external) “stye”

111
Q

What is the SSX sequence of hordeolum external?

A

Pain –> redness –> tenderness of lid margin –> small, round, tender induration –> lacrimation –> photophobia –> foreign body sensation –> pustule on lid margin –> ruptures –> heals spontaneously

112
Q

What condition is acute inflammation of meibomian gland, usually more severe than its other type, has pain, redness, edema is more localized, abscess can form, spontaneous rupture is rare, and recurrence is common?

A

Hordeolum (internal)

113
Q

What condition is chronic enlargement of meibomian gland from infection and occlusion of its duct, often following inflammation of the gland? At onset, looks like a stye but painless, chronic stage may appear like BCC or SCC, after a few days, infection resolves leaving a painless, slowly growing, firm mass in the lid.

A

Chalazion or meibomian cyst

114
Q

What is the term for lid inversion?

115
Q

What is the problem with entropion?

A

Lid area is atrophic in the elderly or scarred, then lashes grow inward, causing irritation, blepharospasm, and may lead to corneal ulceration and scarring.

116
Q

What is the term for a lid that turns outward?

117
Q

What is the problem with ectropion?

A

Tissue relaxes with aging resulting in edema, and leads to poor drainage of tears, excess tearing, redness, and irritation

118
Q

What condition has an enlarged lacrimal gland on upper lateral aspect of eye, is tender, red (if acute), painless (if chronic), and can abscess?

A

Dacryoadenitis

119

A

Dacryocystitis

120
Q

Which condition is a congenitally narrowed lacrimal duct in neonates, with excess tearing, may be pus expressed, and usually resolves in 6 months?

A

Daycryostenosis

121

  4. ) intraocular infection after eye surgery
  5. ) retinal artery occlusion
  6. ) retinal detachment
  7. ) eye trauma (foreign bodies, corneal abrasion)
  8. ) orbital cellulitis
  9. ) field defects
