Iritis
Iritis, also known as anterior uveitis, is an inflammatory condition that affects the iris and other structures of the uvea (coloured part of the eye). The exact cause of iritis is often unknown, but it can be associated with general inflammatory conditions or have a genetic predisposition. It may affect one or both eyes and can be recurrent.
Symptoms of Iritis
Red eye: The eye may appear red or bloodshot due to inflammation.
Eye pain: Iritis can cause discomfort or pain in the affected eye.
Sensitivity to light: Photophobia, or sensitivity to light, is common with iritis.
Blurred vision: Vision may become blurry due to inflammation affecting the eye's structures.
Treatment
Treatment of iritis involves managing the inflammation and preventing complications. Steroid eye drops are the primary treatment to reduce inflammation. The frequency of drop usage will depend on the severity of inflammation.
Dilating drops may also be used to reduce pain and prevent adhesions between the iris and the lens.
In severe cases, additional treatments such as steroid creams, tablets, or injections may be necessary.
Possible complications of iritis include:
Elevated eye pressure: Inflammation or the use of steroid drops can increase eye pressure, leading to potential vision loss if left untreated.
Cataracts: Inflammation itself and long-term use of steroid eye drops can contribute to the development of cataracts.
Swelling of the central retina (macular oedema): This can cause blurred vision.
Important considerations for those with iritis
Do not stop using eye drops suddenly, even if symptoms improve, as there may still be residual inflammation in the eye.
Keep follow-up appointments as inflammation may occur without noticeable symptoms.
Iritis is not contagious.
Seek immediate medical attention if symptoms return or worsen after initial treatment.
Early treatment can help reduce the risk of complications and vision loss.
Prolonged use of steroids for iritis should be managed by an eye care specialist to monitor for potential side effects like glaucoma and cataracts.
If you suspect you have iritis or experience any symptoms mentioned above, it is essential to seek prompt evaluation and treatment from an eye care professional to prevent complications and preserve vision.
