Inflammation is usually secondary to obstruction of the nasolacrimal duct. Clinical findings include swelling over the lacrimal sac, redness, tearing, eyelash matting and crusting, and conjunctival redness. Tears and mucopurulence may be expressed from the punctum when pressure is applied over the lacrimal sac. Complications include conjunctivitis and orbital or preseptal cellulitis.
