What is the most common type of anterior scleritis?

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

Answer: (D)

Anterior scleritis shows several patterns, but most cases are non-necrotizing rather than necrotizing. Within that non-necrotizing group, the diffuse form is the most frequent presentation, meaning inflammation sweeps across a broad area of the anterior sclera rather than clustering in a single spot. Clinically, diffuse non-necrotizing scleritis presents with widespread scleral injection and eye pain that’s typically deep and continuous, without actual scleral tissue destruction.

In contrast, nodular non-necrotizing scleritis features a discrete scleral nodule with focal tenderness, which is less common than the diffuse pattern. Necrotizing forms are far less common and tend to be more severe and destructive, with or without inflammation, and they carry a higher risk of vision-threatening complications. So the diffuse non-necrotizing type best fits the most frequent presentation of anterior scleritis.
