FIGURE 4. DACRYOCYSTITIS. COURTESY OF EYEROUNDS.ORG AND DR. ANDREW DOAN (12). Dacryoadenitis involves inflammation of the lacrimal gland itself, which can present as either an acute or a slowly progressive chronic process. In the acute presentation, patients will note a rapid onset of unilateral pain, redness, and swelling in the superotemporal region of the orbit. The more common manifestation of dacryoadenitis, however, is the chronic form in which patients will display unilateral or bilateral painless enlargement that can last more than a month. #Clinical #Ophthalmology #Photo #Dacryocystitis #Nasolacrimal #Duct
