Rheumatoid nodules involving the sclera of the eye may result in scleromalacia. The bluish choroid is visible because of thinning of the sclera. The surrounding bulbar conjunctiva appears slightly atrophic, and superficial vessels are dilated. Focal chronic inflammatory cell infiltration and necrosis may appear in the sclera. When these changes become more extensive, the lesion resembles the subcutaneous nodule of rheumatoid arthritis.
