What are the complications associated with orbital cellulitis?

• A. Conjunctival scarring only.
• B. Cavernous sinus thrombosis, abscess, loss of vision, and possibly death.
• C. Blue scleral discoloration.
• D. Hair loss.

Answer: (A)

Orbital cellulitis is a serious infection behind the orbital septum that can rapidly spread to nearby structures. The key idea is that it can extend beyond the orbit and cause life- and sight-threatening complications. The most significant risks include cavernous sinus thrombosis with multiple cranial nerve palsies and potential death from sepsis, as well as orbital or intracranial abscess formation. The infection can also involve the optic nerve or retina, leading to permanent vision loss, and it can spread intracranially to cause meningitis or a brain abscess. Because of these dangers, prompt recognition and aggressive treatment with IV antibiotics and possible surgical drainage are essential. Conjunctival scarring is not a typical complication of orbital cellulitis, and blue scleral discoloration or hair loss do not fit this condition.
