Posterior scleritis
Updates to Case Attributes
Scleritis is rare, usually underdiagnosed disease that can significantly compromise patient's vision if left untreated. The most common cause of this entity is a non-infectious inflammatory process that can be either idiopathic or secondary to an underlying systemic disease, most commonly rheumatoid arthritis or granulomatosis with polyangiitis.
Anterior scleritis is more common and easily diagnosed clinically. Posterior scleritis, constituting 2-12% of cases, is more difficult to diagnose clinically
MR imaging is the most useful and accurate modality used to diagnose this condition. The most common imaging finding is scleral enhancement and thickening. Other imaging findings include focal cellulitis and optic perineuritis secondary to the involvement of the adjacent optic nerve sheath.
Patient's usually present with orbital pain, which is the most common presenting clinical feature. Limited eye motion, headaches, eye redness and blurred vision may also be present.
In diffusiondiffuse scleritis, differential diagnosis may include posterior uveitis, lymphoma or diffuse melanoma.
