Scleritis

Scleritis is a serious eye condition where the white part of the eye, called the sclera, becomes inflamed and painful. This inflammation can affect your vision and overall eye health if not treated promptly, making it important to recognize the signs early and seek care to manage it effectively.

What Is Scleritis?

Scleritis involves inflammation of the sclera, the tough outer layer that protects the eye. It can be very painful and may signal other health issues, so learning about it empowers you to take better care of your eyes.

Types of Scleritis

Scleritis can present in several forms based on the area of the eye affected and its severity. Knowing your type helps your doctor choose the right treatment.

  • Diffuse anterior: Widespread inflammation over most of the front of the sclera, causing redness and pain.
  • Nodular anterior: Firm, raised, painful bumps on the sclera.
  • Necrotizing anterior: A severe form that can thin the sclera and threaten the eye's integrity.
  • Posterior: Inflammation at the back of the eye that can cause vision changes, sometimes without much visible redness.

How Common Is It?

Scleritis is rare, affecting about 3 to 4 people per 100,000 each year. It most often appears in adults between the ages of 40 and 60 and is slightly more common in women, which may be due to higher rates of autoimmune diseases.

Why the Sclera Matters

The sclera is the tough, protective outer layer that maintains your eye's shape and shields its delicate inner parts from injury. When the sclera is inflamed, its protective function is weakened, which can lead to discomfort and serious complications if left untreated.

Causes and Risk Factors

Scleritis often stems from underlying health issues, such as autoimmune diseases, or less commonly from infections that trigger inflammation in the eye. Identifying these causes can help manage the condition more effectively.

Autoimmune Diseases

Many cases of scleritis are linked to autoimmune disorders, where the body's immune system mistakenly attacks its own healthy tissues. Conditions like rheumatoid arthritis, lupus, granulomatosis with polyangiitis, and inflammatory bowel disease are common causes.

Infections

Infections from bacteria, viruses, fungi, or parasites can sometimes trigger scleritis, especially after an eye injury, surgery, or a corneal ulcer. Treating infections quickly is important to reduce this risk.

Other Triggers

In rare cases, certain medications, severe allergic reactions, or eye injuries can lead to scleritis. A history of eye surgery or exposure to irritants like chemicals may also play a role.

Risk Factors to Watch

Some factors can increase your chance of getting scleritis. Watching for these can help with early detection and management.

  • Having an autoimmune disease.
  • Being middle-aged, especially between 40 to 60 years old.
  • Smoking or having poor overall health, which can worsen inflammation.
  • A family history of inflammatory or autoimmune conditions.

Symptoms of Scleritis

The main signs of scleritis are deep eye pain and redness that do not go away easily. Early recognition of symptoms allows for faster relief and better outcomes.

Common Signs

One of the main symptoms is a severe, deep, aching pain in the eye that can spread to your head, face, or jaw. The eye often looks very red or purplish, and you may experience blurred vision or sensitivity to light.

When Symptoms Worsen

Pain may become stronger with eye movement or at night, making it hard to sleep or focus. In severe cases, the eye may swell or change shape. If pain persists despite over-the-counter medication, it is a strong signal to see a doctor.

Differences from Other Eye Issues

Unlike the gritty, itchy feeling of pink eye (conjunctivitis), scleritis causes a deep, constant pain. And unlike episcleritis, which is a milder inflammation, scleritis can threaten your vision if it is not treated.

Systemic Symptoms

When scleritis is connected to an autoimmune condition, it may be accompanied by symptoms like joint pain, fatigue, fever, or skin rashes. Reporting these symptoms to your doctor is important for a comprehensive diagnosis and treatment plan.

Diagnosis and Tests

Diagnosis and Tests

To diagnose scleritis, an eye doctor will perform a thorough eye exam and may order additional tests. These steps ensure you get an accurate diagnosis and the correct treatment plan.

Eye Exam Process

During an exam, your doctor will use a slit lamp, which is a special microscope with a bright light, to look closely at your sclera. They will check for signs of inflammation and ask about your health history and symptoms to distinguish scleritis from other conditions.

Common Tests

Blood tests are often used to check for autoimmune conditions or infections that could be causing the scleritis. Other tests may also be needed.

  • Imaging, like an ultrasound or CT scan, helps your doctor check the deeper parts of your eye, especially for posterior scleritis.
  • A biopsy, which involves taking a small tissue sample, is rare but may be done to identify specific infections or other unusual causes.
  • Vision tests will track any changes in your sight over time.

What to Expect

You may need more than one visit to confirm the diagnosis, especially if a systemic disease is suspected. Your eye doctor may also work with other specialists, like a rheumatologist, as part of your overall care.

Treatment Options

Treatment for scleritis focuses on reducing inflammation, relieving pain, and addressing any underlying illness. The specific plan will depend on how severe your scleritis is and what is causing it.

Medications

Over-the-counter anti-inflammatory drugs like ibuprofen may help in very mild cases. More often, stronger medications like corticosteroids in pill form or as injections are needed to control the inflammation.

Advanced Treatments

For severe cases, especially those linked to an autoimmune disease, newer drugs called biologics can be used to calm the immune system. If the sclera becomes very thin and is at risk of tearing, surgery may be needed to repair and strengthen it.

Home Care Tips

While following your doctor’s treatment plan is most important, you can also take steps at home to help your recovery and manage discomfort.

  • Use cold compresses on your eyes for comfort.
  • Limit screen time and rest your eyes when they feel strained.
  • Wear sunglasses outdoors to protect your eyes from bright light and wind.
  • Take all your medications exactly as your doctor prescribed.

Treatment duration varies; mild cases may improve in weeks, while those linked to autoimmune diseases may need ongoing treatment for months or years.
Healthy habits like balanced eating, not smoking, and managing stress can help support overall immune health and potentially lower risk.
Yes, if untreated, severe cases of scleritis can lead to permanent vision loss due to damage to the eye.
Scleritis is a deep inflammation of the sclera, while episcleritis is milder and usually causes less pain.
