Eye Conditions

Uveitis and Iritis

There are three different layers of tissue in the eye. The protective outer layer called the sclera, the middle layer called the uvea, and the inner layer called the retina. Uveitis can be described as a broad number of inflammatory diseases that produce redness and swelling within the eye. Uveitis usually occurs within the uvea. It can also affect the lens, retina, optic nerve and vitreous. Uveitis is a serious condition which requires urgent examination and treatment.

What causes uveitis?

It is not always clear what the cause of uveitis is, however, some factors that can cause the condition are infection or injury to the eye, or an underlying health condition. Some of the associated health conditions may include:

  • Autoimmune or inflammatory conditions
  • Viral, bacterial fungal or parasitic infections
  • Immune-deficiency diseases

Symptoms

Depending on the type of inflammation, symptoms may affect one or both eyes.

Symptoms may include:

  • Red eye
  • Blurred vision
  • Eye discomfort or pain
  • Sensitivity to light
  • Increased tear production
  • Black floaters in vision
  • Smaller pupil in affected eye

Treatment

Treatment will depend on what is causing the uveitis and which area of the eye affected. Usually, it is treated with eye drops. If it caused by another condition, treating the underlying condition may eliminate the uveitis. The main aim of treatment is to reduce inflammation and or irritation.

Uveitis is usually treated by one or a combination of medications. Steroids are the commonly used and may delivered in a number of ways including eye drops, tablets or injections. In some cases immunosuppressive agents can also be taken.

What treatments are available for Macular Degeneration?

The type of macular degeneration you have will determine the type of treatment options that are recommended for you.

There is no current treatment or cure for dry macular degeneration, however, nutrition plays an important role in optimising your macular health. A well-balanced diet, with daily intake of green leafy vegetables and fruit, eating fish two to three times a week and handful of nuts a week can assist with keeping your eyes healthy.

There is treatment available for wet macular degeneration, however, it is important to remember that these treatments do not cure the disease but aim to stabilise and maintain the best vision for as long as possible.

A protein called Vascular Endothelial Growth Factor, or VEGF, is mainly responsible for the growth and leaking of new blood vessels that result in a rapid loss of vision.

To stop or slow this process, various drugs that block the protein, called anti-VEGFs, may be injected into the eye. There are several anti-VEGF drugs used to treat wet macular degeneration in Australia. Your ophthalmologist will discuss with you the most appropriate drug.
