Uveitis diseases associated with

The autoimmune rheumatic diseases consists of Rheumatoid Arthritis (RA), Spondylarthritis (SpA), Systemic Lupus Erythematosus (SLE), Polymyositis, Dermatomyositis, Polymyalgia Rheumatica, Acute Temporal Arteritis, Giant Cell Arteritis, Behcet s Disease, Sjorgren s Syndrome, Felty s Syndrome and Mixed Connective Tissue Disease (MCTD). Spondylarthritis (SpA) can be subdivided in Reactive Arthritis (ReA), Ankylosing Spondylitis (AS), Psoriatic Arthritis (PsA), Arthritis associated with the inflammatory bowel diseases are Crohn s disease and Ulcerative Colitis (IBD), Undifferentiated SpA (UspA) and Sacro-ilitis, Juvenile SpA and Acute Anterior Uveitis (AAU). 

An additional clinical use of acetazolamide is unrelated to its ocular hypotensive properties.The 500-mg acetazolamide capsule administered daily for 2 weeks may produce either a partial or a complete resolution of macular edema in patients with cystoid macular edema (CME), retinitis pigmentosa, and chronic intermediate uveitis (pars planitis). Macular edema produced by primary retinal vascular diseases (branch and central retinal vein occlusion and macular telangiectasia) did not respond to acetazolamide therapy. It is believed that acetazolamide may improve visual function if the macular edema stems from retinal pigment epithelial dysfunction. Improved macular edema in these conditions may be associated with fluid movement from the retina to the choroid. However, acetazolamide does not appear to alter macular blood flow. 

Topical ocular steroid administration also may cause the development of cataracts in both children and adults. Use of topical steroids for several years to eliminate redness associated with contact lens wear resulted in PSC formation as well as glaucoma and visual field loss. The opacities associated with steroid administration resemble those produced by ionizing radiation and ocular disease such as uveitis, retinitis pigmentosa, and retinal detachment. They differ from opacities associated with diabetes and trauma but are indistinguishable from lens changes associated with posterior subcapsular age-related cataract. 

Several extended-release devices able to deliver a consistent level of corticosteroid to the retina have been devised. Two will be presented in this chapter, although other devices are under evaluation or in the development pipeline at the time of writing. The primary indications for these devices are persistent macular edema associated with several conditions, including diabetic retinopathy, retinal vascular occlusive disease, cataract surgery, and posterior uveitis. 

The main side effect associated with oral acyclovir, valacyclovir, and femciclovir is intestinal disturbance such as nausea and vomiting. Acyclovir is available in an 800-mg tablet that does not contain lactose therefore it is less likely to cause lactose-related diarrhea. Lower dosages are recommended for treatment of elderly patients with impaired creatinine clearance. Perhaps the most significant factor in fevor of antivirals is that they minimize the common complications of the disease, including dendriform keratopathy, stromal keratitis, and anterior uveitis. 

Iris In cases of granulomatous disease, inflammatory nodules may be detected in the iris. Nodules seen at the pupillary margin are termed Koeppe nodules, whereas Busacca nodules occur within the iris stroma. Iris nodules have been identified in association with a variety of disorders, including sarcoidosis, tuberculosis, leprosy, syphiUs, multiple sclerosis, Vogt-Koyanagi-Harada syndrome, and Fuchs hete-rochromic iridocycUtis.The pupillary margin and iris surfece should also be examined for neovascular membranes in cases of chronic uveitis. Additionally, iris... 

A number of laboratory tests and ancillary studies may aid in the management of uveitis. Such testing is indicated when the patient presents with any of the following conditions (1) recurrent uveitis or uveitis unresponsive to treatment, (2) bilateral uveitis, (3) uveitis with posterior involvement, or (4) uveitis associated with signs or symptoms suggestive of systemic disease. 

CME occurs in other somewhat imcommon posterior segment disease states. Pars planitis is associated with CME at a frequency of 28% of cases, and CME is the primary cause of vision loss in chronic severe uveitis. 

Ocular complications including iritis, uveitis, episcleritis, and conjunctivitis occur in up to 10% of patients with IBD. The most commonly reported symptoms with iritis and uveitis include blurred vision, eye pain, and photophobia. Episcleritis is associated with scleral injection, burning, and increased secretions. These complications may parallel the severity of intestinal disease, and recurrence after colectomy with ulcerative colitis is uncommon. 

There are no consistently recommended therapies for hver disease, skin manifestations, or uveitis associated with IBD. Some reports suggest that these manifestations are worse during exacerbations of the intestinal disease and that measures improving intestinal disease will improve these systemic manifestations. Unfortunately, this association has not been demonstrated consistently. Liver transplantation... 

Intraocular injections are associated with significant complications and often must be repeated at regular intervals in patients with a chronic disease such as uveitis. Similar difficulties are associated with periocular injections although the complication rate is lower and those that do occur are usually less severe. The main... 

Corticosteroids have been used to treat a variety of ocular diseases. Traditionally, delivery of corticosteroids for posterior-segment eye diseases has been achieved through oral systemic therapy and periocular injections. Oral corticosteroids have not been widely used to treat DME, but when used for posterior inflammatory uveitis, they require high concentrations to reach therapeutic levels in the posterior segment. These high doses often result in systemic side effects (24). Periocular corticosteroid administration often must be repeated and may be associated with complications such as ptosis and inadvertent needle penetration of the globe. 

Chlorambucil (0.1 to 0.2 mg/kg/d for 3 to 6 weeks) will provide palhation in chronic lymphocytic leukemia, mahg-nant lymphomas including lymphosarcoma, giant follicular lymphoma, and Hodgkin s disease. In addition, it has been used in the treatment of uveitis and meningoencephalitis associated with Behcet s disease. Chlorambucil is absorbed orally, metabolized extensively, and the metabolite is... 

Uses Daclizumab has been studied in cases of active posterior uveitis [206°] in children with refractory and steroid-resistant/depen-dent graft-versus-host disease [207°, 208°] for recalcitrant ocular inflammatory disease [209°] in multiple sclerosis [210° 211°] and in patients with moderate to severe persistent asthma [212 ]. Daclizumab has been used as induction therapy before liver transplantation [213°, 214 ] and renal transplantation [215°], as well as in active anterior uveitis associated with juvenile idiopathic arthritis [216°].
