Which type of anterior scleritis is characterized by nodules?

Explanation:
Focal scleral nodules are the hallmark of this form of anterior scleritis. It presents with one or more firm, raised nodules on the sclera, often with marked eye redness and eye pain, but without scleral thinning or necrosis. This distinguishes it from diffuse non-necrotizing scleritis, which lacks discrete nodules and shows widespread scleral injection, and from necrotizing forms, which involve tissue death and thinning (with or without inflammation). So, the presence of nodules specifically points to nodular non-necrotizing scleritis.
