Which symptom is NOT associated with orbital cellulitis?

Orbital cellulitis is an infection of the tissues surrounding the eye and is characterized by several specific clinical symptoms. The symptoms commonly associated with this condition include pain with eye movement, proptosis (which is the forward displacement of the eye), and diplopia (double vision). These symptoms arise due to the inflammation and involvement of the structures within and around the orbit.

Severe vision loss, while it can occur in some complications of orbital cellulitis—such as from severe intraocular pressure or direct damage to the optic nerve—is not a classic or defining symptom of the condition itself. Instead, it is more indicative of complications that arise from the infection rather than an immediate symptom seen in all cases of orbital cellulitis. Regularly, patients with orbital cellulitis retain their vision unless there are secondary complications that affect the optic nerve or the eye itself.

Thus, recognizing that severe vision loss is not a primary symptom helps differentiate orbital cellulitis from other ocular or orbital conditions that might present with visual disturbances as more prominent features. In summary, while severe vision loss can be a concern in the context of orbital cellulitis, it is not a typical symptom that would be immediately observed in patients with this condition.
