Visual changes and ocular pain in periorbital versus orbital infections are more suggestive of which condition?

• A. Preseptal cellulitis
• B. Orbital cellulitis
• C. Conjunctivitis
• D. Uveitis

Answer: (B)

Visual changes with ocular pain point to infection inside the orbit rather than just the eyelid tissues. When the infection is behind the orbital septum, it involves the orbital contents and often causes painful eye movements, limited extraocular movements, proptosis, and sometimes decreased vision. These red flags indicate orbital cellulitis, a condition that can threaten vision and spread seriously if not treated promptly with imaging and IV antibiotics. In contrast, preseptal (periorbital) cellulitis is confined to the eyelids and surrounding soft tissues in front of the orbital septum. It can produce eyelid swelling and redness but typically does not affect vision or cause pain with eye movement. Conjunctivitis mainly presents with surface redness and discharge without deep orbital signs, and uveitis presents with photophobia and deep-eye pain with cells in the anterior chamber rather than a post-septal infection.
