Chemical and environmental irritants contribute Ulcerative: Involves the lash follicle & the Meibomian glands of the eyelid. May be pustules at the base of the hair follicle that crust & bleed. Lashes break easy. Dry Eye Frequent hordeola or chalazia Facial/scalp seborrhea Immunocompromised state Acne DM Isotretinoin Ocular burning, eyelid margins red w/ scaling or crusting Pain Itching, tearing, chalazia, recurrent styes, photophobia, small ulceration at eyelid margin, broken or absent eyelashes Sebaceous carcinoma, Basal cell carcinoma, Squamous cell carcinoma, Dry eye syndrome, Conjunctivitis, Contact dermatitis, Atopic Kerato-conjunctivitis, Herpes simplex infection, Preseptal cellulitis, Acute dacryocystitis, Ocular rosacea TX: Warm compress; daily lid scrubs; erythromycin, quinolone or bacitracin ophthalmic ointment for anterior blepharitis. Consider oral ABX for resistance (Doxycycline or Tetracycline) Disinfect contacts Lid messages NONE Hordeolum An acute infection of one of the glands in the eyelid. The most common associated organism is Staphylococcus aureus More common in children and adolescents Localized tenderness, erythema, edema of eyelids; internal lesions pointing to external or internal eyelid surface; external lesions pointing to eyelid margin Pain Sebaceous carcinoma, Basal cell carcinoma, Squamous cell carcinoma, Dry eye syndrome, Conjunctivitis, Contact dermatitis, Atopic Kerato-conjunctivitis, Herpes simplex infection, Preseptal cellulitis, Acute dacryocystitis, Ocular rosacea TX: Warm compress; lid scrubs for recurrent lesions NONE Chalazion A granulomatous infection of a Meibomian gland More common in adults Nontender in chronic lesions; localized erythema, edema of eyelids No Pain Sebaceous carcinoma, Basal cell carcinoma, Squamous cell carcinoma, Dry eye syndrome, Conjunctivitis, Contact dermatitis, TX: Warm compress; daily lid scrubs; lid message; intralesional steroid injection NONE Atopic Kerato-conjunctivitis, Herpes simplex infection, Preseptal cellulitis, Acute dacryocystitis, Ocular rosacea Conjunctivitis Inflammation of the conjunctiva covering the front of the eye from a causative agent (bacteria, virus, allergen) Allergic conjunctivitis is seen more in Spring and Summer. Bacterial is seen more in pediatric population. ALLERGIC: Pruritus; conjunctival hyperemia, chemosis; 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 RED FLAGS
