1 Conjunctiva

2 Baby picture of the day!

4 Papillae vs. Follicles Papillae Follicles
Think “pABillae” = Allergic & Bacterial Red dots of varying size (red due to central vessel) Non-specific Chlamydia, toxic, viral Avascular/white nodules, filled with lymphocytes

5 Cysts Benign Fluid-filled

6 Concretions Deposits of mucous secretions
Sometimes foreign body sensation

7 Nevi Benign proliferation of melanocytes

8 Primary Acquired Melanosis (PAM) Conjunctival Melanosis
Unilateral acquired pigmentation Flat, indistinct margins Progression from PAM Proliferation of melanocytes Metastasize to the liver

9 Conjunctival Intraepithelial Neoplasia (CIN)
Conjunctival Squamous Cell Carcinoma #1 conjunctival malignancy Unilateral pre-malignant Elevated, gelatinous mass with neovascularization Progression from CIN Malignant

10 Bacterial Conjunctivitis
Simple Gonococcal Children H. influenzae or Staph Acute redness, discharge Neisseria gonorrhea HYPERACUTE onset Severe purulent discharge

11 Adenoviral Conjunctivitis
Acute non-specific conjunctivitis Most common Red eye, follicles, tearing All 3 of these are very contagious! Pharyngo- conjunctival Fever (PCF) “Swimming pool conjunctivitis” Pharyngitis Acute follicular conjunctivitis Fever Epidemic Keratoconjunctivitis (EKC) Most serious Pain, corneal involvement

12 Molluscum Contagiosum
Associated with poor hygiene, children DNA pox virus Infectious Dome-shaped, umbilicated, waxy nodules Chronic follicular conjunctivitis

13 Allergy Allergic conjunctivitis Vernal Keratoconjunctivitis (VKC)
Atopic Keratoconjunctivitis (AKC) Giant Papillary Conjunctivitis (GPC)

14 Allergic Conjunctivitis
Seasonal allergic conjunctivitis Perennial allergic conjunctivitis Type 1 hypersensitivity History of allergy Ex: pollen allergy Type 1 hypersensitivity History of allergy Ex: dust allergy

15 Vernal Keratoconjunctivitis (VKC)
Rare Boys <10yo Family history of atopy Itching Papillae on superior lid Shield ulcer

16 Atopic Keratoconjunctivitis (AKC)
Young adults History of atopy Not seasonal Dennie’s lines (atopy) Inferior papillae

17 Giant Papillary Conjunctivitis
Associated with silicone hydrogel (SiHy) contact lens wear, mechanical trauma Non-infectious, immune, inflammatory response Itching, discharge, decreased wearing time Papillae of superior lid

18 Chlamydia/Trachoma Chlamydia Chlamydia is the most common STD!
Acute follicular conjunctivitis, becomes chronic Inferior follicles Usually unilateral Most common cause of ophthalmia neonatorum

19 Chlamydia/Trachoma Trachoma
Leading cause of preventable blindness worldwide Follicular conjunctivitis Bilateral Late-stage: Arlt Lines, tarsal conjunctival scarring, trichiasis

20 Phthiriasis Palpebrarum (Pediculosis Ciliaris)
Pubic lice on eyelashes Sleeves at base of lashes Itching Follicular conjunctivitis, bruises from bites

21 Subconjunctival Hemorrhage
Causes: valsalva (coughing), medications (blood thinners), hypertension, clotting disorders

22 Pingueculum Associated with UV exposure & chronic dryness
Abnormal growth of conjunctiva

23 Pterygium Associated with UV exposure & chronic dryness
Abnormal growth of the conjunctiva onto the cornea, destroys Bowman’s membrane Stocker’s line = iron deposit along leading edge of pterygium Blocks vision & causes irregular astigmatism
