NURS 5433 Module 1
Blepharitis
nonulcerative form associated w/ seborrhea
- commonly seen in those w/ trisomy 21
- tends to affect people w/ psoriasis, seborrhea, eczema, allergies, and lice infestations
- contributing factors: chemical or environmental irritants, use of eye makeup and
contact lenses
ulcerative form
- involves lash follicle and meibomian glands of eyelid
- may be pustules at base of hair follicles that may crust or bleed
- lashes become thick and break easily
Blepharitis RF
- dry eye
- recurrent hordeola or chalazia
- seborrhea of face and scalp
- immunocompromised
- acne
- DM
- isotretinoin
,Blepharitis exam finding
ulcerative
- itching, tearing, chalazia, recurring styes, photophobia, small ulceration at eyelid
margin with loss or breakage of eyelashes
seborrheic
- chronic inflamed eyelid, erythma, greasy scaling to anterior eyelid, missing lashes,
seborrheic dermatitis of eyebrows and scalp
Blepharitis Treatment (rx/pharm)
- warm wet compresses
lid scrub w/ baby shampoo
lid massage to express meibomian glands
- remove contact lenses and disinfect
pharm management
- bacitracin, erythromycin, quinolone ointments
- consider oral atbx for resistant infections
- doxycyline 100 mg po BID
- tetracycline 250 mg po QID
Hordeolum (stye)
erythematous, tender lump within eyelid
- external hordeolum: inflammation/infection of eyelid margin affecting hair follicles of
eyelashes
- internal hordeolum: inflammation/infection of meibomian glands
,Chalazion
- granulomatous infection of a meibomian gland
- painless swelling on eyelid
- may be tender and erythematous before evolving into a nontender lump
- blepharitis is frequently associated w/ chalazia
Chalazion Treatment
- warm moist compresses
- intralesional steroid injection
- lid massage
- lid scrubs
Conjunctivitis (red eye)
inflammation of conjunctiva covering the front of eye
common causes
- bacterial, viral, or fungal
- sexual transmission and ophthalmia neonatorum
- HSV 1
- trachoma
- toxicity (from an inciting agent of some sort)
- allergy
- viral
- adenoviruses, Coxsackie virus, varicella, HSV, herpes zoster virus
Conjunctivitis assessment
ALLERGIC: Pruritus; conjunctival hyperemia, chemosis; a watery or stringy discharge
, BACTERIAL: Photophobia w/ blepharospasm; mucopurulent discharge w/ eyelash
mattering; edema; hyperemia; preauricular adenopathy only w/ hyperacute disorder
VIRAL: Acute onset often A/W systemic illness; photophobia or foreign body sensation;
preauricular adenopathy; hyperemia; chemosis; watery discharge; classic dendritic
corneal lesion present w/ herpes simplex; periocular lesions present w/ herpes zoster
opthalmicus
Conjunctivitis diagnostics
- snellen
- visual acuity
- dilated pupil exam for proptosis, optic nerve dysfunction, decreased visual acuity,
diplopia, or anterior chamber inflammation
- fluorescein staining to rule out corneal involvement or keratitis
- blue penlight illumination to visualize corneal scratches, corneal dendrites, or corneal
ulcerations
Conjunctivitis red flags
- diminished visual acuity, photophobia, severe foreign body sensation preventing pt
from keeping eye open, corneal opacity, fixed pupil, severe headache w/ nausea
- refer to ophthamologist
conjunctivitis management
allergic
- topic decongestant antihistamine combos (OTC)
- naphazoline hydrochloride 0.025% (Naphcon- A)
- naphazoline-antazoline 0.3% (vasocon-A)
- levocabastine hydrochloride 0.05% (Livostin)
- emedastine 0.05% (emadine)
