Overview
Other diagnostic studies for blepharitis include Slit lamp examination, tear break up time (TBUT), and measurement of tear osmolarity.[1][2]
Other Diagnostic Studies
Other diagnostic studies for blepharitis include:[1][2]
- [Slit lamp|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 blepharitis concurrent with dry eye syndrome. On measurement of tear osmolarity, dry eye syndrome is characterized by the tear osmolarity of 316 mOsm/L or greater.
