Overview
Other diagnostic studies for blepharitis include slit lamp examination, tear break up time (TBUT), and measurement of tear osmolarity.[1][2][3]
Other Diagnostic Studies
Other diagnostic studies for blepharitis include:[1][2][3][4]
Slit lamp examination
On slit lamp examination, blepharitis is characterized by:
- Meibomian gland enlargement
- Waxy secretions at the gland openings
- Lid margin neovascularization and dilation of existing blood vessels
- Ulcerations along the eyelid margin
- Corneal nodules
- Corneal margin ulcer
- Superficial corneal pannus
Images

Tear Break Up Time
On tear break up time (TBUT), blepharitis is characterized by tear film instability and rapid evaporation.
Measurement of Tear Osmolarity
Other diagnostic studies for blepharitis include measurement of tear osmolarity. Blepharitis concurrent with dry eye syndrome may be characterized by tear osmolarity of 316 mOsm/L or greater.
Microscopic evaluation of eyelashes
On microscopic evaluation of eyelashes, chronic blepharoconjunctivitis may be characterized by the presence of Demodex mites.
