Chorioretinitis may be caused by infection or by autoimmune diseases.
It is sometimes caused by an infection that you had when you were young, although the symptoms may not appear for 10 to 20 years.
Factors that may increase your chance of chorioretinitis:
Autoimmune disease, such as:
Rheumatoid arthritisSacrcoidosisPolyarteritis nodosaGranulomatosis with polyangiitis
Infectious disease, such as:
HIV/AIDSWeak immune statusExposure to pets, raw or undercooked meat, or contaminated waterHLA-A29 gene
Chorioretinitis may cause: Pain or redness in the eyeBlurred vision, or seeing floating objects in your visionSensitivity to light or glareExcessive tearingSensation of sparks or flashes of lightImpaired night visionImpaired color visionDistortion of objects
Your doctor will ask about your symptoms and medical history. A physical exam will be done.
To prepare for a complete eye exam, drops may be put in your eyes to numb them and to dilate your pupils. The slit lamp, a special microscope to examine the eye, will focus a high powered beam of light into your eye to examine the cornea and other eye structures. The doctor may measure the pressure in your eyes.
Your bodily fluids may be tested. This can be done with blood tests.
Talk with your doctor about the best treatment plan for you.
Medications may vary depending on the cause. Other causes will also need to be treated.
Chorioretinitis may be treated with: Corticosteroid eye drops or injections to control inflammationMedications for an infection, which may be present or possibleDilating drops—to prevent the iris from sticking to the lens underneath, which will reduce discomfort
