Answer

Infections of the lacrimal system are classified based on the location of the infection; they include the following (see Presentation, Workup, Treatment, and Medication):

  • Blepharitis - Inflammation of the lid margins; anterior blepharitis affects the area of the lid where the eyelashes attach; posterior blepharitis affects the inner portion of the eyelid margin that is in contact with the eye; blepharitis primarily affects older persons (mean age 40-50 years) [4]

  • Canaliculitis – Inflammation of the canaliculi

  • Dacryoadenitis - Inflammation of the lacrimal gland

  • Dacryocystitis - Inflammation of the lacrimal duct or sac; obstructed lacrimal ducts causing dacryocystitis are common in infants and usually resolve by age 9-12 months (see the image below) [5]

    Acute dacryocystitis. Acute dacryocystitis.
