Which statement is true about anterior scleritis?

• A. The most common type of anterior scleritis is diffuse non-necrotizing.
• B. The nodular non-necrotizing type is the most severe form.
• C. Necrotizing with inflammation is not a real category.
• D. Posterior scleritis is more common than anterior.

Answer: (A)

Anterior scleritis comes in several forms, but the most common by far is diffuse non-necrotizing anterior scleritis, where inflammation spreads across a large portion of the sclera without tissue death. This pattern typically presents with pronounced eye pain, redness, and tenderness, and the sclera remains structurally intact. The nodular non-necrotizing form is a localized scleral nodule, which can be painful but is not as common as the diffuse type. Necrotizing anterior scleritis with inflammation is a serious, destructive variant with scleral thinning and risk of complications, but it is relatively rare. Posterior scleritis involves the back part of the sclera and is less common than anterior forms. So, the statement describing the diffuse non-necrotizing type as the most common accurately reflects the usual presentation.
