Pars Planitis

Peripheral Uveitis


  • Patients with pars planitis may present with bullous retinoschisis and/or exudative retinal detachment.[ncbi.nlm.nih.gov]
  • Intermediate uveitis falls into the category of "vitritis" for purpose of differential diagnosis and therefore has to be differentiated from sarcoidosis, amyloidosis, active retinitis and recent trauma.[docksci.com]
  • Vitreous inflammation leads to exudate and cytokine formation, which mainly falls to the inferior eye, eliciting an endotheliopathy-like reaction.[crimsonpublishers.com]
  • Intermediate uveitis falls into the category of "vitritis" for purpose of differential diagnosis and therefore has to be differentiated from sarcoidosis, amyloidosis, active retinitis and recent trauma.[docksci.com]

Weight Gain
  • After a short course of oral prednisone, BCVA of the left eye improved from 20/200 to 20/50, but the patient could not tolerate the side effects, such as weight gain.[crimsonpublishers.com]

Blurred Vision
  • The Humphrey ultrasound biomicroscope was used for examination of the right eye of a 17-year-old boy, referred to our clinic because of blurred vision. The lens showed a posterior subcapsular cataract precluding fundus visualization.[ncbi.nlm.nih.gov]
  • Symptoms of pars planitis include blurred vision, floaters, flashes, redness of the eye and eye pain.[monmouthretina.com]
  • This may lead to blurred vision; dark, floating spots in the vision; and progressive vision loss. As the condition advances, cataracts, retinal detachment, or macular edema (fluid within the retina) may develop.[xpertdox.com]
  • The most common presenting symptoms are floaters and blurred vision. Diffuse vitreous cells, haze, snowballs and snowbanks are typical findings of pars planitis. Peripheral retinal vasculitis, optic disc edema and… CONTINUE READING[semanticscholar.org]
Anterior Uveitis
  • Resources - Pars planitis Other names: Iritis; Uveitis ; Choroiditis; Chorioretinitis; Anterior uveitis; Posterior uveitis[checkorphan.org]
  • —Pars planitis is a form of anterior uveitis, the cause of which is not known.[jamanetwork.com]
  • Evidence of anterior uveitis is minimal - a few cells may occasionally be evident in the anterior chamber. Anterior and posterior synechiae are rare. Posterior subcapsular cataracts are frequent.[gpnotebook.co.uk]
  • Topical steroids are employed only if there is a concomitant anterior uveitis. Oral prednisone is more commonly used. However, once a commitment to use oral steroids is made, typically they must be used for months.[louisvillediabeticeyedoctor.com]
Visual Impairment
  • Conclusions: : Pars planitis in pediatric patients may cause significant visual impairment, and its presentation may vary considerably.[iovs.arvojournals.org]
  • Complications Decreased Visual Acuity Severe Visual Impairment : 35% Legally blind: 10% Iris scarring Impaired pupillary movement Secondary Glaucoma XIII.[fpnotebook.com]
  • […] vision loss, pain on eye movement, double vision, oscillopsia, numbness or weakness in one or more limbs, tingling sensation or pain.The patient may also experience electric-shock sensations that occur with certain head movements (Lhermitte’s sign), tremor[digital.crojournal.com]

  • ’s sign), tremor, lack of coordination, fatigue, dizziness and a visual heat intolerance (Uhtoff’s sign).[digital.crojournal.com]


  • The diagnosis workup including blood work, MRI, and neurological exam were ordered; results, treatment, and prognosis for this case is discussed.[aaopt.org]
  • Systemic workup for conditions associated with intermediate uveitis including sarcoidosis evaluation was negative.[joii-journal.springeropen.com]
  • Although most pediatric IU cases are idiopathic, a systemic workup is recommended to evaluate for underlying disorders (see “Possible Etiologies”).[aao.org]
Retinal Phlebitis
  • The remaining five eyes from four patients showed similar findings and included retinal phlebitis, disc and macular oedema, and the presence of a 'snowbank' over the inferior peripheral retina and pars plana.[ncbi.nlm.nih.gov]

  • Three patients (five eyes) received scatter diode or argon photocoagulation treatment alone.[ncbi.nlm.nih.gov]


  • PURPOSE: To report the demographics and clinical characteristics, therapy logarithm, and prognosis of children with pars planitis.[ncbi.nlm.nih.gov]
  • A good prognosis can be expected for those who undergo appropriate treatment. The condition does not usually lead to permanent blindness Complications, such as glaucoma and cataract, can worsen the prognosis.[dovemed.com]


  • Although the etiology of pars planitis remains obscure, clinical evidence suggests a strong association with multiple sclerosis.[mayoclinic.pure.elsevier.com]
  • Clinical and histopathological findings suggest an autoimmune etiology, most likely as a reaction to endogenous antigen of unknown source, with T cells predominant in both vitreous and pars plana infiltrations.[ncbi.nlm.nih.gov]
  • Multiple sclerosis is a chronic inflammatory demyelinating disease of the central nervous system that is presumed to be an autoimmune etiology.[aaopt.org]
  • Although an autoimmune process with a genetic predisposition has been suggested, its etiology still remains unknown. The most common presenting symptoms are floaters and blurred vision.[semanticscholar.org]
