Posterior orbital cellulitis: case report and literature review.
It is rare for isolated sphenoid sinusitis to cause orbital cellulitis. We present a rare case of posterior orbital cellulitis, so caused, together with a review of the relevant literature. ⋯ Isolated sphenoid sinusitis is rare but can cause significant visual disturbance and permanent loss of vision. Vague symptoms unsupported by clinical signs at presentation are a feature of posterior orbital cellulitis. The presented case highlights the problem, and the need for a high index of clinical suspicion even in the absence of firm clinical signs, in order to prevent permanent visual loss.
