Lids & Lashes
Baby picture of the day!
Trichiasis Inward-turned eyelashes
Madarosis Missing eyelashes
Dermatochalasis Weakened orbital septum causes sagging eyelid skin
Ptosis/pseudoptosis
Superior visual field loss
Blepharitis Staph blepharitis – discharge, morning crusting
Seborrheic blepharitis – eyelash flakes
Hordeolum Acute staph infection of glands
Tender Internal – meibomian glands
External – Zeis/Moll glands (“stye”)
Chalazion Chronic sterile inflammation of meibomian gland
Hard Painless
Recurrent: think sebaceous gland carcinoma
Ectropion / Entropion Eyelid oriented away from globe
Concerns: exposure keratopathy, epiphora
Eyelid oriented toward the globe
Concerns: trichiasis
Floppy Eyelid Syndrome Lid eversion during sleep
Associated with sleep apnea in obese men
Morning redness & SPK
Benign Essential Blepharospasm (BEB) Bilateral involuntary closure of eyes
Orbicularis oculi, procerus, AND corrugator
Idiopathic
Myokymia Involuntary unilateral twiching of eyelids
Orbicularis oculi only
Causes: sleep deprivation, caffeine, stress
Malignant Eyelid Tumors Basal Cell Carcinoma (BCC)
Squamous Cell Carcinoma (SCC)
Sebaceous gland carcinoma
Malignant melanoma
Basal Cell Carcinoma (BCC) #1 eyelid cancer Malignancy of basal cell layer of epidermis
Risk factor: sun Pearly nodule, telangiectasia
“Rodent ulcer”
Squamous Cell Carcinoma (SCC) #2 eyelid cancer
More dangerous than BCC
Associated with actinic keratosis (elevated, red, scaly lesion)
Sebaceous Gland Carcinoma Neoplasm of sebaceous glands (meibomian & Zeis)
Associated with recurrent chalazia
Madarosis
Malignant Melanoma Most lethal primary skin cancer
Malignancy of melanocytes
Signs of Malignancy ABCDE:
Asymmetry Border irregularity
Color differences
Large diameter Enlargement
