Pars planitis
Pars planitis
Pars planitis (pronounced: pahrz plan-eye-tis) is a form of uveitis, specifically a subset of intermediate uveitis. The term is derived from the Latin pars, meaning part, and the Greek planitis, meaning inflammation.
Definition
Pars planitis is an inflammation of the pars plana, a part of the eye located in the ciliary body and adjacent to the retina. This condition is characterized by the presence of white, inflammatory, exudative deposits known as "snowbanks" or "snowballs" in the periphery of the retina or pars plana.
Symptoms
Common symptoms of pars planitis include blurred vision, floaters, and red eye. In severe cases, it may lead to retinal detachment or neovascularization, which can cause vision loss.
Causes
The exact cause of pars planitis is unknown, but it is thought to be an autoimmune disease. It has been associated with other systemic diseases such as multiple sclerosis and sarcoidosis, but it can also occur in isolation.
Treatment
Treatment for pars planitis typically involves the use of corticosteroids to reduce inflammation. In some cases, immunosuppressive drugs may be used. Vitrectomy may be necessary in severe cases or if there is a significant impact on vision.
Prognosis
The prognosis for pars planitis is generally good with treatment, although it can recur. Regular follow-up with an ophthalmologist is important to monitor for potential complications.
