Episcleritis ddx

Episcleritis is a common inflammatory condition that affects the episcleral tissue, which is the thin layer of tissue located between the conjunctiva and the sclera of the eye. The hallmark symptom of episcleritis is redness and inflammation of the eye, which can be accompanied by discomfort or pain. However, the differential diagnosis of episcleritis can be challenging, as it shares many similarities with other ocular conditions.

One condition that can be easily confused with episcleritis is conjunctivitis, also known as pink eye. Both conditions present with redness and inflammation of the eye, but conjunctivitis tends to be more diffuse and affects the conjunctiva, whereas episcleritis tends to be more localized and affects the episcleral tissue.

Scleritis is another condition that can be mistaken for episcleritis. However, scleritis tends to be more severe and can cause more significant pain and discomfort, as well as potentially leading to complications such as corneal thinning or scleral perforation.

Inflamed conjunctival cysts and phlyctenular keratoconjunctivitis are other conditions that can present with redness and inflammation of the eye, but they typically have unique features that distinguish them from episcleritis.

When diagnosing episcleritis, it is essential to take a thorough medical history and perform a comprehensive eye examination. Treatment for episcleritis typically involves artificial tears, topical steroids or oral nonsteroidal anti-inflammatory drugs, but treatment may vary depending on the severity and underlying cause of the condition.
