Clinical InformationClinical

  • Scleritis

    refers to any inflammation of the sclera including episcleritis, a benign condition affecting only the episclera, which is generally short-lived and easily treated. classic scleritis, on the other hand, affects deeper tissue and is characterized by higher rates of visual acuity loss and even mortality, particularly in necrotizing form. its characteristic symptom is severe and general head pain. scleritis has also been associated with systemic collagen disease. etiology is unknown but is thought to involve a local immune response. treatment is difficult and includes administration of anti-inflammatory and immunosuppressive agents such as corticosteroids. inflammation of the sclera may also be secondary to inflammation of adjacent tissues, such as the conjunctiva.

Patient EducationClinical

Eye Diseases

Even if your eyes feel healthy, you could have a problem and not know it. That's why regular eye exams are so important. Refractive errors are the most common type of vision problem that makes it hard to see clearly. But some eye conditions or diseases don't have any symptoms and can lead to a permanent loss of vision.
