The diagnostic test for iritis typically involves an eye examination, which may include a slit-lamp examination, an intraocular pressure measurement, and other tests such as a fundus examination. Depending on the results of the eye exam, the doctor may order additional tests such as imaging studies (ultrasound, CT scan, MRI) to look for signs of inflammation. Other tests such as blood tests may be ordered to check for associated conditions or to rule out other causes of eye problems.
Slit-Lamp Examination
The slit-lamp exam is used to examine the eye and look for signs of inflammation in the iris, lens, and other structures inside the eye. During the exam, the doctor will use a special microscope to look for signs of redness, swelling, or other abnormalities. The doctor will also measure the pressure inside the eye (intraocular pressure) to rule out glaucoma.
Imaging Studies
Imaging studies such as ultrasound, CT scan, or MRI may be used to look for signs of inflammation or other problems in the eye. These tests can help the doctor to determine the cause of the inflammation and can be used to measure the size and shape of the eye.
Blood Tests
Blood tests may be ordered to check for associated conditions or to rule out other causes of eye problems. These tests may include a complete blood count, an erythrocyte sedimentation rate (ESR), and other tests such as antinuclear antibody (ANA) testing.
