Your Question

Once an individual with pars planitis loses vision, can they get it back?  And what are the different surgeries that can treat pars planitis?

Our Answer

We have identified the following information that we hope you find helpful. If you still have questions, please contact us.

Can vision be restored after it has been affected by pars planitis?

Inflammation in pars planitis decreases the clarity of an affected individual's vision by causing the following complications: macular edema, clouding of the fluid in the center of the eye, inflammation of another part of the eye called the optic papilla (papillitis), inflammation of blood vessels in the eye (vasculitis), and cataracts.  The authors of one study stated that it is best to treat inflammation in pars planitis quickly and completely to reduce the chance of complications that may affect vision clarity.  Their research showed that appropriate treatment of pars planitis helps to restore vision.[1]

How might pars planitis be treated?

The first approach to treating pars planitis is to inject steroids near the eye to control inflammation.  If several injections are given without success, non-steroidal anti-inflammatory drugs (NSAIDs, including aspirin) or steroid medications (such as prednisone) may be taken by mouth.  If these are also unsuccessful, other medications may be given to reduce the body's immune responses (medications called immunosuppressants, such as methotrexate). 

If medications are not effective, surgery may be considered.  Cryosurgery has been performed in affected individuals to remove eye tissue that has inflammation.  Although this surgery has been shown to be effective in restoring clarity of vision, there are concerns that it may cause damage to other parts of the eye.  Another surgery, known as vitrectomy, can be done to remove cloudy fluid (vitreous humor) from the eye.[1]
