1. Lids & Lashes

2. Baby picture of the day!

4. Trichiasis  Inward-turned eyelashes

5. Madarosis  Missing eyelashes

6. Dermatochalasis  Weakened orbital septum causes sagging eyelid skin  Ptosis/pseudoptosis  Superior visual field loss

7. Blepharitis  Staph blepharitis – discharge, morning crusting  Seborrheic blepharitis – eyelash flakes

8. Hordeolum  Acute staph infection of glands  Tender  Internal – meibomian glands  External – Zeis/Moll glands (“stye”)

9. Chalazion  Chronic sterile inflammation of meibomian gland  Hard  Painless  Recurrent: think sebaceous gland carcinoma

10. Ectropion / Entropion  Eyelid oriented away from globe  Concerns: exposure keratopathy, epiphora  Eyelid oriented toward the globe  Concerns: trichiasis

11. Floppy Eyelid Syndrome  Lid eversion during sleep  Associated with sleep apnea in obese men  Morning redness & SPK

12. Benign Essential Blepharospasm (BEB)  Bilateral involuntary closure of eyes  Orbicularis oculi, procerus, AND corrugator  Idiopathic

13. Myokymia  Involuntary unilateral twiching of eyelids  Orbicularis oculi only  Causes: sleep deprivation, caffeine, stress

14. Malignant Eyelid Tumors  Basal Cell Carcinoma (BCC)  Squamous Cell Carcinoma (SCC)  Sebaceous gland carcinoma  Malignant melanoma

15. Basal Cell Carcinoma (BCC)  #1 eyelid cancer  Malignancy of basal cell layer of epidermis  Risk factor: sun  Pearly nodule, telangiectasia  “Rodent ulcer”

16. Squamous Cell Carcinoma (SCC)  #2 eyelid cancer  More dangerous than BCC  Associated with actinic keratosis (elevated, red, scaly lesion)

17. Sebaceous Gland Carcinoma  Neoplasm of sebaceous glands (meibomian & Zeis)  Associated with recurrent chalazia  Madarosis

18. Malignant Melanoma  Most lethal primary skin cancer  Malignancy of melanocytes

19. Signs of Malignancy  ABCDE:  Asymmetry  Border irregularity  Color differences  Large diameter  Enlargement
