Blepharitis

1.3. A: Blepharitis is associated with crusting of the eyelashes, thickening of the eyelids, telangiectatic vessels along the lid margins, and plugging of the meibomian glands.

1.4. Blepharitis may be associated with rosacea that is manifested by telangiectatic vessels on the skin and, as in the advanced case shown here, with rhinophyma.

1.7. In atopic blepharitis, there is an eczematoid reaction of the eyelids.

1.11.C: In severe adenoviral conjunctivitis, the patient may have lid ecchymoses in addition to subconjunctival hemorrhages.

1.12. D: Giant papillary conjunctivitis is characterized by papillae of the superior tarsus, which are thought to be caused by an allergic reaction to the coating on foreign bodies such as contact lenses or exposed sutures.

1.14. Acute bacterial conjunctivitis with mild lid swelling, conjunctival injection, and discharge along the lid margin.

FIG. 2.6. A: Conjunctivitis. B: Chemosis. C: Facial swelling caused by an allergic reaction.

Blepharitis.

FIG. 15.10. Allergic conjunctivitis with lid edema and conjunctival infection.

1.11. A: Viral conjunctivitis is associated with an acute follicular reaction. In follicles, vessels course on the surface from the periphery of the lesions toward the center rather than emerging in the center, as is the case in papillae.

FIG. 15.11. Allergic conjunctivitis with chemosis. Note the swollen conjunctiva extending up to the border of the cornea.

1.6. Seborrheic blepharitis is associated with crusting of the eyelids without meibomian gland inflammation and with seborrheic dermatitis of the eyebrows and scalp.

1.15. A: Hyperacute gonococcal conjunctivitis, with copious mucopurulent discharge and lid swelling.
