Symptoms might also show up in places you don’t expect, like your eyes. Here’s what you need to know.
How Psoriatic Arthritis Affects Your Eyes
Both psoriasis and psoriatic arthritis are autoimmune diseases. That means they cause your body to attack itself by mistake. This can trigger inflammation in certain parts of the body, including your eyes.
If your eyes are irritated and you have psoriasis, you may have uveitis. That's a term for any inflammation inside your eye. It can lead to swelling and damaged eye tissue. Uveitis may affect one or both eyes. Symptoms include:
- Blurry vision
- Dark, floating spots in your line of vision called floaters
- Eye pain and redness
- Light sensitivity
Ongoing inflammation can lead to other eye issues. These include:
Conjunctivitis (pinkeye). This is inflammation or infection of the layer that covers the white part of your eyes. Symptoms include:
- Red and itchy eyes
- Feeling like there’s something in your eye
- Crusty discharge
- Tearing up
Your eye doctor can treat pinkeye.
Glaucoma. This is a group of conditions that damage your optic nerve. It often starts with inflammation that causes a buildup of pressure in your eye. Symptoms include:
You may not have any of these if the disease is in its early stages. That's why regular eye exams are important. Your eye doctor can catch it even if yo’re not showing symptoms. Glaucoma can also be a side effect of taking corticosteroids for psoriatic arthritis. Talk to you doctor about how to lower this risk.
Cataracts. That ’s when inflammation turns the clear lens of your eye cloudy. Symptoms can include:
- Trouble seeing at night
- Blurry vision
- Double vision in one eye
- Changes to your glasses or contacts prescription
Steroids you put on your skin or take by mouth for long periods of time can raise your risk for this disease. Cataracts are usually treated with surgery. Your eye doctor will take out the cloudy lens and put in an artificial one.
