Eyelid lesions – “Stye”Chalazion: A painless (usually, but acutely painfull), slowly enlarging bump,
usually chronic, formed by inflammation (not infection) of the meibomian glands.
Hordeolum: A localized infection or inflammation, usually acute, involving hair follicles of the eyelashes or meibomian glands.

HORDEOLUM/CHALAZION:TREATMENT
⦿ Goal› To promote drainage
⦿ Treatment› Acute/subacute: Warm-hot compresses and
eyelid massage (try to gently express the MG)› Chronic: incision and currettage or steroid
injection or can try topical gtt like Azasite or steroid gtts

BLEPHARITIS
⦿ AKA anterior blepharitis (lashes mostly)⦿ Inflammation of lid margin⦿ Associated with dry eyes⦿ Seborrhea causes dried skin and wax on
base of lashes⦿ May have Staphylococcal infection⦿ Symptoms: lid burning, lash mattering
Disorders of the Ocular Adnexa

Meibomian Gland Dysfunction
⦿ Probably most common cause of chronic eye irritation
⦿ Inadequate quantity and/or quality of meibomian gland secretions / oil
⦿ Can also have inflammatory component, hence AKA posterior blepharitis

How the Eye Works
Blepharitis and Meibomian Gland Dysfunction
These are very commonly seen together (anterior + posterior blepharitis) and treatment is similar and overlaps

Treatment⦿ Blepharitis
› Cleaning the eyelid margins (i.e. warm water with baby shampoo or commercial eyelid cleaner e.g. Ocusoft or Sterilid - http://www.dryeyezone.com/encyclopedia/lidscrubs.html
› Antibiotic ointment or antibiotic & steroid combination› Demodex blepharitis – TTO or Cliradex (4-Terpineol)› Hypochlorous acid - NEW (Avenova or Ocusoft)
⦿ Meibomian gland dysfunction› Warm compresses 2-3 times daily and eyelid massage (new:
Lipiflow - in-office thermal treatment)› Omega-3 FA’s
⚫ Diet: Fish, walnuts, etc⚫ Supplement: Fish oil tablets
› Oral antibiotics in severe cases (ocular rosacea) i.e. Doxycycline⦿ Both
› Artificial tears, best choices are name-brand and preservative-free

EXPOSURE KERATITIS: CAUSES AND MANAGEMENT
⦿ Due to incomplete lid closure⦿ Manage with lubricating
solutions/ointments⦿ Tape lids shut at night⦿ Careful about patching without taping –
may cause a corneal abrasion

MANAGEMENT⦿ Goals:
› Promote rapid healing› Relieve pain› Prevent infections
⦿ Treatment:› 1% cyclopentolate (or another cycloplegic)› Topical antibiotics
⚫ Drops polytrim, tobrex, fluoroquinolone, etc⚫ Ointment erythromycin, bacitracin/polymyxin, etc
› ± Pressure patch or tape lids shut ok but not necessary in all cases
› Bandage contacts another option› ± Oral analgesics, usually OTC options enough

CHEMICAL INJURY
⦿ A true ocular emergency⦿ Requires immediate irrigation with
nearest source of water, can use Morgan Lens hooked up to normal saline or ringers lactate, may need 8-10 liters, pH should return to 7-7.4.
⦿ Cederroth (sterile buffered isotonic sodium chloride) - buffer, even better than saline
⦿ Management depends on offending agent
