Idiopathic anterior Uveitis

Iridocyclitis


Presentation

  • CONCLUSION: A disturbed expression of Fas and FasL on T cells is present in patients with Behcet's disease, VKH syndrome, and idiopathic anterior uveitis, which may be involved in the perpetuation and recurrence of uveitis.[ncbi.nlm.nih.gov]

  • In the present study, we assessed choroidal thickness in patients with unilateral, acute, anterior uveitis.[journals.plos.org]
  • Tearing, lid puffiness, and some drooping of the eyelid may also be present. Inflammation or infection in other parts of the eye may produce similar symptoms.[eyewiki.aao.org]

Chemosis
  • Ocular examination typically exhibits limbal vascular injection (ciliary flush) with occasional chemosis. Intraocular pressure is typically normal. However, severe chronic inflammation can lead to elevated intraocular pressure.[medtextfree.wordpress.com]
  • On examination, conjunctival chemosis can be prominent. Efforts should be made identify the causative agent if it is not readily apparent. Oral anti-histamines and cold compresses are helpful and the swelling usually resolves quickly, within days.[antimicrobe.org]

Workup

  • The basic workup for acute anterior uveitis includes an HLA-B27, syphilis testing, and testing for sarcoid (CXR at least–the utility of angiotensin converting enzyme (ACE) testing is debated among uveitis specialists as many factors impact the level.[eyewiki.aao.org]
  • A laboratory workup might include: A complete blood count (CBC) RPR or FTA-ABS (for syphilis) A chest x-ray (for sarcoid) A PPD (for tuberculosis) HLA-B27 What the Doctor Sees When a doctor examines the patient, he or she will use a slit lamp that projects[improveyourvision.com]

Treatment

  • The treatment period was at least 9 months (mean 20 months). We observed relapse in 4 patients during treatment, 13 patients are still in remission.[em-consulte.com]
  • Larger randomized trials are needed to better assess treatment effect and safety. Google Scholar[secure.emmes.com]
  • However the threat to vision in the long term is worse if adequate treatment is not given, and so the balance usually lies on the side of using whatever steroid treatment is necessary to completely stop the inflammation.[uveitis.net]
  • Apply the proven treatment strategies of hundreds of top experts in your field.[books.google.com]
  • There was no significant difference in mean IOP of the uveitic eye before and after treatment (13.8 3.9 and 14.3 2.9 before and after treatment, respectively, P 0.372 by paired t-test).[journals.plos.org]

Etiology

  • Etiology has, through extensive testing, both laboratorial and clinical, not been proven and thus the patient has been classified as having idiopathic scleritis.[sciencedomain.org]

  • However, only 1% of people who carry the HLA-B27 allele develop acute anterior uveitis. [1] Pathophysiology The exact pathophysiology is not known. Inflammation of the iris and the ciliary body causes a breakdown of the blood-ocular barrier.[emedicine.medscape.com]
  • Risk Factors HLA-B27 allele, anklyosing spondylitis, psoriatic arthritis Pathophysiology Unknown.[eyewiki.aao.org]
  • Causes Uveitis has more than 85 known causes, originating from several different pathophysiological processes—surgery, autoimmune disorders, infections, malignancy, or toxins.[odpcli.com]

Prevention

  • There is evidence that prevention of toxic aldehyde formation and accumulation may prevent inflammation and fibrosis associated with ocular inflammatory disease.[aldeyra.com]
  • Uveitis the pressure can be raised due to the inflamed iris "sticking" to the lens (adhesions or synechiae) preventing the fluid from passing through the pupil.[uveitis.net]
  • Anterior Uveitis – Management Goals of management Preserve visual acuity Relieve ocular pain Eliminate ocular inflammation Identify the source of inflammation Prevent formation of synechiae Control the IOP 44.[slideshare.net]
