Key Takeaways About Scleritis.
- Scleritis is a serious inflammation of the tough white outer wall of your eyeball called the sclera.
- Unlike minor eye redness, scleritis causes deep, throbbing pain that often radiates to your head and jaw.
- It is often linked to immune system conditions like rheumatoid arthritis or lupus affecting your whole body.
- Prompt medical care with specialized anti-inflammatory medicine or steroid eye drops is crucial to protect your vision.
- Never ignore persistent deep eye pain or vision changes. Always see an eye doctor right away.

What Is Scleritis?
To understand scleritis, you first need to know a little bit about how your eye is built. Your eye is like a tiny camera with several protective layers. The white outer wall of your eyeball is called the sclera. This tough, fibrous layer acts like a strong shield to protect the delicate inner parts of your eye. When this white wall becomes badly inflamed and swollen, doctors call the condition scleritis.
Scleritis is a rare but very serious medical condition that causes deep pain. It is much more severe than common pink eye or simple eye irritation. When the sclera gets inflamed, the blood vessels inside it swell up and turn your eye a deep purple or dark red color. Because your sclera has many nerve endings, any swelling causes intense, deep aches that can wake you up from a sound sleep.
Most of the time, scleritis happens because of an overactive immune system. Your body's defense system mistakenly attacks its own healthy tissues, including your eye wall. This is often connected to systemic autoimmune diseases like rheumatoid arthritis, lupus, or vasculitis. In rare cases, bacteria or fungi can cause the infection. Because the inflammation can weaken the eye wall, getting fast medical help from an eye specialist is essential to prevent permanent vision loss.
Check If You Have It: Symptoms and Causes.
Spotting the warning signs of scleritis early helps you get the medical help you need before damage occurs. The symptoms usually start slowly and get worse over a few days. You might feel a dull, constant ache deep inside your eye socket. This pain is so strong that standard over-the-counter pain relievers often do not touch it.
Here are the main symptoms of scleritis you must watch out for:
- Intense, deep, throbbing pain located inside or around your eyeball that often disrupts your sleep.
- Pain that spreads outward into your forehead, your brow line, your temples, or your jawbone.
- A dark red, purple, or crimson discoloration on the white part of your eye that does not improve with simple eye drops.
- Extreme sensitivity to light, making it painful to open your eyes in bright rooms or outdoors in the sunlight.
- Blurry vision, double vision, or a noticeable decrease in your overall visual clarity.
- Excessive tearing and watering from the affected eye as your body reacts to the deep inflammation.
Understanding what triggers this inflammation helps you and your doctor find the root cause. While some cases have no clear trigger, up to half of all people with scleritis have an underlying autoimmune disease. Your doctor will check for conditions where your immune system attacks your joints and tissues. Common links include rheumatoid arthritis, systemic lupus erythematosus, inflammatory bowel disease, and various types of blood vessel inflammation.
Comparing Scleritis and Episcleritis.
People often confuse scleritis with a much milder condition called episcleritis. Knowing the difference between the two helps you understand why doctors treat them so differently. The table below compares these two eye conditions clearly.
| Feature. | Scleritis. / Episcleritis. |
|---|---|
| Location of Inflammation. | Scleritis.: Deep in the thick white outer wall of the eye (sclera). Episcleritis.: In the thin layer of tissue sitting on top of the sclera (episclera). |
| Pain Level. | Scleritis.: Severe, deep, throbbing pain that radiates to the head and jaw. Episcleritis.: Mild discomfort, irritation, or a scratchy feeling without deep pain. |
| Eye Color Change. | Scleritis.: Deep red, purple, or bluish-red hue across the white of the eye. Episcleritis.: Bright pink or localized red patches that look less severe. |
| Vision Impact. | Scleritis.: Can cause blurred vision and severe complications if left untreated. Episcleritis.: Does not affect your vision or damage the inner eye structures. |
| Medical Urgency. | Scleritis.: High urgency. Requires immediate medical evaluation and prescription drugs. Episcleritis.: Low urgency. Often clears up on its own or with mild lubricating drops. |
When to Call the Doctor or Seek Emergency Care.
Scleritis is a medical concern that requires professional diagnosis and treatment. You should never try to treat deep eye pain at home with over-the-counter redness relief drops.
- Seek immediate emergency medical attention (call 911 in the US/Canada, 999 in the UK, or visit your nearest Emergency Department) if you experience sudden severe eye pain accompanied by sudden vision loss.
- Schedule an urgent appointment with an optometrist or ophthalmologist right away if you notice persistent deep eye ache, purple redness, or extreme light sensitivity lasting more than a day.
- Contact your doctor promptly if you have a known autoimmune disease like rheumatoid arthritis and develop new eye redness or pain.
