Scleritis sometimes occurs in people who have a bodywide inflammatory disease.
The main symptom is a deep, painful ache in the eye.
Sometimes imaging tests are done to confirm the diagnosis.
Treatment typically begins with corticosteroids.

Symptoms of Scleritis
Symptoms of scleritis include pain in the eye (typically a deep ache) that is often constant and severe enough to interfere with sleep and reduce appetite. Other symptoms include eye tenderness, increased watering of the eye, and sensitivity to bright light. Redness that is purplish in color occurs over part or all of the eye.
Rarely, inflammation is severe enough to cause a hole to form in the eyeball (perforation) and loss of the eye. Such severe inflammation is called necrotizing scleritis. People who have necrotizing scleritis often have many years of problems such as autoimmune disorders (for example, rheumatoid arthritis Rheumatoid Arthritis (RA) Rheumatoid arthritis is an inflammatory arthritis in which joints, usually including those of the hands and feet, are inflamed, resulting in swelling, pain, and often destruction of joints.... read more , granulomatosis with polyangiitis Granulomatosis with Polyangiitis Granulomatosis with polyangiitis often begins with inflammation of small- and medium-sized blood vessels and tissues in the nose, sinuses, throat, lungs, or kidneys.

Diagnosis of Scleritis
A doctor's evaluation of the symptoms and appearance of the eye
Sometimes imaging tests
Doctors diagnose scleritis by its symptoms and appearance during a slit-lamp examination Slit-Lamp Examination A person who has eye symptoms should be checked by a doctor.

Treatment of Scleritis
Sometimes surgical repair
To treat scleritis, doctors usually give corticosteroids taken by mouth (such as prednisone). Very rarely, nonsteroidal anti-inflammatory drugs taken by mouth are enough treatment for mild cases.

People who are at risk of a perforation may need surgical repair.
Prognosis for Scleritis
About 14% of people who have scleritis develop significant decrease in vision within 1 year, and 30% develop significant decrease in vision within 3 years.
