Slide 2

Introduction Definition : Inflammation of the uveal tract ( the iris, ciliary body and choroid ). Anatomical Classification : 1. Aggravation of the iris ( iritis or foremost uveitis ). Accompained by expansion vascular penetrability: White cells ciculasting in fluid funniness of foremost chamber Proteins Picked out by its light disseminating properities( in the light emission light ) . 2. Aggravation of the standards plana ,back ciliary body, ( Cyclitis or Intermediate uveitis ). 3. Irritation of the back section ( Posterior uveitis ) . Inflamtory cells in the vitreous gel. 4. Aggravation of choroid or retina ( choroiditis and retinitis ). 5-Inflammation of front and back uveitis together ( Panuveitis ).

Slide 3

Epidemiology Incidence of uveitis : 15 for every 100 000 individuals. 75 % of these are Interior uveitis . - About 50 % of patients, have a related systemic infection.

Slide 4

History The patient grumble , incorporate : 1-Ocular torment ( less with back uveitis or choroiditis ) 2-Photophobia . 3-Blurred vision . 4-Redness of the eye .

Slide 5

3-Skin Problems : 1. Erythema nodosum ( Painfull raised red sores on the arm and legs ), present in agranulomatous illness, for example, sarcodosis and Behcet,s infection . 2. Patint with Behcets malady might likewise have : thrombophlebitis, dermtographia, oral and genital ulceration . 3. Psoriasis ( in relationship with joint pain ) may be accompained by uveitis . 4-Joint illness : AAU : connected with Ankylosing spondylitis with back agony . In youngsters : adolescent constant joint pain may be connected with uveitis Reiter,s sickness ( traditionally urethritis, conjunctivitis and seronegative joint inflammation ) may be connected with foremost uveitis . 5-Infectious Disease : Syphilis with its mutable sign can bring about uveitis ( es. Back choroiditis ) Herpetic sickness ( shingles ) may bring about uveitis. Cytomegalovirrus (CMV ) may bring about uveits ( es. In patient with AIDS Fungulinfections and metastatic contaminations may bring about uveitis ( usyally in immunocompromised patient )

Slide 6

Signs On examination : 1-Decrease visual sharpness . 2-Eye will be inflammed in intense front malady . 3-Inflamatory cells may be noticeable amassed together on endothelium of cornea ( es. Poorly )( Keratitic pps ). 4-Slight light examination : uncover aqueouscells and flare. In the event that irritation disjoin , White cells gather as a mass poorly ( hypopyon ) 5-Dilatation of vessels on the iris . 6-Iris may hold fast to lens ( back synechiae or PS ). 7-IOP may be raised. 8-cells may be available in the vitreous. 9-retinal or choroidal foci of irritation may be available . 10-Macular odema may be available .

Slide 7

Investigation Aimed at deciding a systemic affiliation and are coordinated to some degree by the sort of uveitis . A. Foremost Uveitis : More likely connected with ankylosing spondylitis and HLA-writing may help to affirm conclusion . Vicinity of vast KPs and knobs on iris recommend sarcoidosis; a mid-section radiograph, serum calcium and serum angiotensin changing over enzym would be proper In toxoplasmic retinochoroiditis , the center of irritation ofen at edge of an old provocative choroidal scar. B. Back Uveitis : - May have an irresistible or systemic incendiary reason - Disease, for example, CMV in HIV-positive patients have characteristc appearance with fitting history ( no requirement for further indicative test ) - Associated symptomns may help toward systemic sickness ( e.g. fever, looseness of the bowels, weight reduction ) NOTE : Not all instance of foremost uveitis requir examinations at first presentation unless systemic manifestations are available .

Slide 8

Treatment Goals of treatment : 1-Relieveing agony and inflamation in the eye. 2-Preventing harm to visual structures. 3-Preventing visual misfortune because of retinal or optic nerve harm. Pharmacological treatment Anterior Uveitis : Dilatation of the understudy keep the arrangement of Posterioor Synechiae , by isolating it from the foremost lens container. ( Synechiae interfer with ordinary dilatation of student ) . Dilatation is accomplished by : Homatropine, Cyclophentolate or Atropine drops. ( Atropine > delayed activity ) To break any synechiae , begin with concentrated beginning Cycophentolate, Phenylepherine , and Tropicamide drops. - Subconjunctival infusion of mydriatics may help to break safe synechiae.

Slide 9

B. Back Uveitis : Visual misfortune may happen because of damaging procedures created by : 1-Retina it self ( e.g. in toxoplasma or CMV ) OR 2-Fluid gathering in the macula\'s layers ( Macular Odema ) This oblige antiviral or anti-microbial or systemic steriod treatment Some uncommon however disjoin type of uveitis e.g. that connected with Behcet,s malady requir methodical immunosuppressive medications, for example, : Azathioprine , or Cyclosporine . Longe term treatment may be essential

Slide 10

Specific Conditions Associated with Uveitis There are countless ailment connected with Uveitis :

Slide 11

Special Conditions Ankylosing spondylitis Definition : Seronegative ( RF – ve ) inflamatory joint pain of the spine . Signs : Typical of foremost uveitis. Treatment : Ocular treatment + discontinuous mitigating + Physiotherapy. Anticipation : Recurrent assault . The out search for vision is great ( if intense assault treated early & energetically ). Adolescent perpetual arthrits Definition : A seronegative joint inflammation which display in youngsters , either systemic illness with fever and lymphadenopathy, specific or polyparticular joint pain. Signs : white eye + indications of a foremost uveitis + waterfall + glucoma ( because of uveitis or steroid drops . Treatment : Ocular treatment + systemic treatment for joint infection + glucoma hard to be dealt with ( if solution come up short , syrgery may be obliged ).

Slide 12

Special Conditions Toxoplasmosis The contamination may be inherent or aquired ( 50-75 % inborn ) Treatment : - Reactivated injuries will subsidebut treatment is obliged if macula or optic nerve is undermined or if the provocative reaction is exceptionally extreme. + systemic steroids are adminstered with antiproto zoal e.g. clidamycin ( tend to pseudomembranous colitis from clindamycin ) ( patient ought to be cautioned that if loose bowels dvelops they ought to look for restorative help promptly )

Slide 13

Patient Informations 1,2 : Take all pharmaceutical , don’t skip dosages , Take it 1 hr befor or 2 hr after dinners [ Enhance F ] . Missed dosage - take it as quickly as time permits.
