What is the most severe form of anterior scleritis?

• A. Diffuse non-necrotizing
• B. Nodular non-necrotizing
• C. Necrotizing with inflammation
• D. Necrotizing without inflammation

Answer: (C)

The most severe form of anterior scleritis is the one where scleral tissue is being destroyed (necrosis) and there is active inflammation at the same time. That combination—necrosis with ongoing inflammatory activity—drives rapid and extensive tissue damage, including scleral thinning or melt, which can threaten the eye's structure and lead to perforation. It also tends to be associated with more aggressive systemic autoimmune processes, so it usually requires strong, prompt immunosuppressive treatment to prevent vision loss. Other forms lack this destructive necrosis or lack the inflammatory component. Diffuse or nodular non-necrotizing scleritis involve inflammation without scleral melting, so while painful and sight-threatening, they don’t show the same level of tissue destruction. Necrotizing without inflammation has scleral necrosis but without the inflammatory signs, which is a different and typically less aggressive pattern than when active inflammation accompanies the necrosis.
