What potential complication arises due to dacryocystitis?

Dacryocystitis is an inflammation of the lacrimal sac, typically resulting from a blockage in the nasolacrimal duct. One significant complication that can arise from dacryocystitis is the development of orbital cellulitis. This condition occurs when the infection spreads from the lacrimal sac into the surrounding orbital tissues, leading to swelling, pain, and potentially more serious consequences such as vision loss or the spread of infection to the brain.

Orbital cellulitis demands immediate medical intervention, as it encompasses inflammation and infection of the soft tissues around the eye, which can have severe implications if not treated promptly. The increased pressure and presence of infection can also interfere with ocular functions and vision.

In contrast, while conditions like corneal scarring, intranasal obstruction, and chronic dry eye syndrome may occur due to various ocular or systemic issues, they are not direct complications of dacryocystitis in the same way that orbital cellulitis is. The primary concern with dacryocystitis is the risk of the infection spreading, which makes orbital cellulitis the most relevant and serious complication associated with this condition.
