Overview
Other diagnostic studies for blepharitis include Slit lamp examination, Tear break up time (TBUT),and Measurement of tear osmolarity.
Other Diagnostic Studies
Slit Lamp Examination
Slit lamp examination is currently used for differentiating between anterior and posterior blepharitis. On slit lamp examination, blepharitis is characterized by:
- Meibomian gland Enlargement (posterior blepharitis)
- Waxy secretions at the gland openings (posterior blepharitis)
- Lid margin neovascularization and dilation of existing blood vessels
- Ulcerations along the eyelid margin.
- Corneal nodules
- Corneal margin ulcer
- Superficial corneal pannus
Tear Break Up Time
On tear break up time (TBUT), blepharitis is characterized by tear film instability and rapid evaporation.
Measurement of Tear Osmolarity
Measurement of tear osmolarity is used for diagnosing concurrent dry eye syndrome.
