Acute and subacute iridocyclitis: Understanding the condition

Acute and subacute iridocyclitis are two types of uveitis, which is inflammation of the uvea, the middle layer of the eye. In iridocyclitis, the inflammation affects the iris and ciliary body, which are responsible for controlling the amount of light that enters the eye and focusing the lens.

Symptoms of acute and subacute iridocyclitis

The symptoms of acute and subacute iridocyclitis are similar and can include:

  1. Eye pain and redness
  2. Sensitivity to light
  3. Blurred vision
  4. Tearing or watering of the eyes
  5. Small or irregularly shaped pupil

If you experience any of these symptoms, it is important to see an eye doctor as soon as possible to determine the cause and begin treatment.

Treatment options for acute and subacute iridocyclitis

Treatment for acute and subacute iridocyclitis may include:

  • Topical corticosteroids to reduce inflammation
  • Mydriatic eye drops to dilate the pupil and reduce pain
  • Nonsteroidal anti-inflammatory drugs (NSAIDs) to relieve pain and reduce inflammation
  • Oral steroids in severe cases

In addition to medication, your eye doctor may recommend rest and avoiding activities that may exacerbate the condition, such as reading or using a computer for extended periods of time.

Preventing acute and subacute iridocyclitis

While there is no guaranteed way to prevent acute and subacute iridocyclitis, there are steps you can take to reduce your risk:

  1. Protect your eyes from injury by wearing safety glasses when working with tools or participating in sports.
  2. Wash your hands frequently to reduce the risk of infection.
  3. Get regular eye exams to monitor for any changes in your vision and eye health.
  4. Manage chronic conditions such as arthritis or autoimmune disorders that may increase your risk of uveitis.

By taking these steps, you can help reduce your risk of developing acute and subacute iridocyclitis and other types of uveitis.
