Q

What are some common ways to assess lid margin disease?

A
  • TBUT (reduced due to stasis, reduction of oil in tear film)
  • Bulbar Conjunctiva Stain (appears before corneal stain)
  • Corneal Stain
  • Lissamine Green
  • Digital Expression
  • Forceful expression
  • Palpebral conjunctival signs

Q

Describe Meibomian Keratoconjunctivitis

A
  • meibomian gland disease with associated corneal changes
  • Sign and Symptoms: inflammation around the glands
  • glands difficult or impossible to express
  • expressions is thick
  • posterior inflammation
  • tear film is unstable with debris
  • associated papillary hypertrophy
  • associated keratitis (10, 2, 4 and 8’ o clock lesion)
  • clear zone between lesions and limbus
    Tx: steroids
    Lid Changes: Madarosis, pachylblepharon, scalloped margins
    Associations: rosacea, seborrhea

Q

Describe Meibomian Seborrhea or MGD

A
  • overproduction of sebaceous material, rapid turnover of epithelial cells
  • precursor to MKC
  • responsible for C/L intolerance
  • Associated with rosacea and seborrhea
  • Tx: lid hygiene, Restasis and Azasite
  • Grading 1-4
