Blepharitis (Yumori) Flashcards
Anterior blepharitis
irritation and inflammation at the base of the eyelashes caused by bacteria (staphylcoccal or seborrhoeic)
Blepharitis: symptoms
burning, grittiness, associated dry eye symptoms
ANterior Blepharitis: Signs
- Staphylococcal signs include: collarettes, increased vascularization, trichiasis and irregular lid margin
- Seborrhoeic signs include: greasy anterior lid margins, stuck together lashes, soft scales
bleph treatment: eyelid therapy
use a washcloth to wipe gently against lashes and lid margins. in the shower, with your eyes closed, wash the base of your lashes with a washcloth. Can also treat with topical antibiotic ointment (erythromycin or bacitracin oph ung OHS OU)
What should you be careful of with blepharitis?
intractable, unilateral, or asymmetric belpharitis: may be a manifestation of sebaceous carcinoma of the eyelid
Posterior blepharitis (Meibomitis)
caused by: meibomian gland dysfunction, changes in meibum. Leads to: ocular surface irritation, increased tear evaporation, hyperosmolarity, unstable tear film (TBUT)
Posterior bleph symptoms
burning, grittiness, associated dry eye symptoms
Meibomitis signs
expressibility (%glands secreting), secretion quality (clear vs white). You have to push!
Meibomitis treatment
- Warm compresses twice a day. Place heated mask over eyelids for 5-10min/session with your eyes closed. don’t put pressure on eyes
- Eyelid massages: pinch gently along the eyelid margin (base of lashes)
- Oral tetracyclins: reduces lid and conj bacteria load, decreases keratinization and bacterial lipase production, reduce matrix metalloprotinase activity
Oral tetracyclins for meibomitis
doxycycline 50mg qd, tetracycline 250-500mg qd
contraindicated in pregnant/nursing women and children use erythromycin 200mg BID
