Are most cases of scleritis anterior or posterior?

• A. Anterior
• B. Posterior
• C. Equally
• D. Unknown

Answer: (A)

Most cases of scleritis involve the anterior part of the sclera. Inflammation tends to be most evident and clinically detectable in the anterior sclera, producing the classic red, tender red eye with scleral injection that can be seen on exam. Posterior scleritis, while important, is much less common and can present without obvious anterior signs, often requiring imaging to diagnose and sometimes mimicking other posterior segment or orbital conditions. Because anterior scleritis accounts for the vast majority of cases, it is the correct answer.
