2
RED EYE- UVEITIS
  • Brig Mazhar Ishaq
  • Advisor in Ophthalmology,
  • Comdt Armed Forces Institute Of Ophthalmology,
  • Rwp

3
ANATOMICAL CLASSIFICATION
  • ANTERIOR UVEITIS
  • IRITIS
  • IRIDOCYCLITIS
  • INTERMEDIATE UVEITIS
  • POSTERIOR UVEITIS
  • PANUVEITIS

4
POSTERIOR UVEITIS
  • Involves the fundus posterior to the vitreous
    base
  • - Retinitis - Choroiditis -
    Vasculitis

5
SARCOIDOSIS
  • Presentation
  • - Acute
  • - Insidious
  • Ocular features
  • - AAU - CAU
  • - Intermediate
  • - Candlewax drippings
  • - Multifocal choroiditis
  • - Retinal granulomas

6
TUBERCULOSIS
  • Anterior segment involvement
  • Tuberculous uveitis
  • - Anterior uveitis, - Choroiditis
  • - Periphlebitis

7
TOXOPLASMOSIS
  • Presentation
  • - Unilateral sudden onset of floaters
  • Signs
  • - Spill-over anterior uveitis -
    Satellite lesion - Multiple foci are uncommon
    - Severe vitritis (headlight in the fog)

8
TOXOPLASMOSIS
9
BEHCET SYNDROME
  • Recurrent oro-genital ulceration
  • Ocular features
  • AAU - cold abscess
  • Retinitis
  • Retinal vasculitis
  • Vitritis,

10
BEHCET SYNDROME
11
FUNGAL UVIETIS
12
INVESTIGATIONS
  • Indications
  • Recurrent granulomatous anterior uveitis
  • Bilateral disease
  • Systemic manifestations with out a specific
    diagnosis
  • Confirmation of suspective ocular picture such as
    HLA-A29 testing in birdshort chorioretinopathy

13
NOT NECESSARY
  • Single attack of mild unilateral acute anterior
    uveitis
  • A specific uveitis entity
  • When a systemic diagnosis compatible with the
    uveitis is already apparent

14
INVESTIGATIONS
  • Obtain a history, attempting to define the
    etiology.
  • Complete ocular examination, including an IOP
    check and a dilated fundus examination.

15
SKIN TESTS
  • Tuberculin skin test (montoux Heaf)
  • Intradermal inj of purified protein
  • Positive
  • Induration of 5-14 mm with in 48 hours
  • Negative
  • Excludes TB
  • May occure in advanced disease

16
PATHERGY TEST
  • Increased dermal sensitivity to needle trauma
  • Behcet syndrome
  • Rarely positive in absence of systemic activity
  • Pustule formation

17
SEROLOGY
  • SYPHILIS
  • Non-treponemal tests
  • RPR or VDRL
  • Primary infection
  • Monitor disease activity
  • Response to therapy

18
  • Immunofluorescent antibody test
  • Haemagglutination test

19
Enzyme-linked Immunosorbent Assay (ELISA)
  • Antibodies in aqueous (more specific)
  • Other conditions (cat-scratch fever
    toxocariasis
  • Antinuclear Antibody (ANA)
  • In children with JIA who are at high risk of
    developing ant uveitis

20
ENZYME ASSAY
  • Angiotensin converting enzyme (ACE)
  • Nonspecific test
  • Granulomatous disease like
  • - Sarcoidosis (elevated in 80 in acute)
  • - TB
  • - Leprosy
  • Lysozyme
  • Good sensitivity but less speceficity for
    sarcoidosis

21
HLA TISSUE TYPING
  • HLA type Associated disease
  • B27 Spondyloarthropathies
  • A29 Birdshot chorioretinopathy
  • B51 Behcet syndrome
  • HLA-B7 POHS APMPPE
  • HLA-DR2

22
IMAGING
  • Fluorescein angiography (FA)
  • Retinal vasculitis
  • CMO
  • Indocyanine angiography (ICG)
  • Better for choroidal disease

23
  • Ultrasonography (US)
  • It is useful in opaque media especially in
    excluding a RD or intraocular mass
  • Optical coherence tomography(OCT)
  • Detecting CMO
  • Identify vitreoretinal traction as a mechanism of
    CMO

24
BIOPSY
  • Histopathology still remains the gold-standard
  • conjunctiva And Lacrimal gland
  • - Sarcoidosis
  • Aqueous samples
  • - For (polymerase chain reaction) PCR
  • - Viral retinitis (occasionally)
  • Vitreous biopsy
  • - Infectious endophthalmitis

25
RADIOLOGY
  • Chest X-rays
  • - To exclude TB and Sarcoidosis
  • Sacro-illiac joint X-Rays
  • - Diagnosis of spondyloarthropathy
  • CT MRI
  • - Sarcoidosis
  • - Multiple sclerosis
  • - Primary intraocular lymphoma

26
TREATMENT
  • AIM
  • Prevent vision threatening complications
  • Relieve patients discomfort
  • Treat the underlying cause
  • FOUR GROUP OF DRUGS
  • Mydriatics
  • Steroids
  • Cyclosporine
  • Cytotoxic agents

27
TREATMENT
  • Mydriatics
  • To give comfort
  • To prevent formation of posterior synechia
  • To break down synechia
  • Drugs (atropine, homatropine, scopolamine,
    tropicamide)

28
TREATMENT
  • Steroids (mainstay of treatment)
  • Topical administration
  • Complications (glaucoma, posterior sub capsular
    cataract, corneal complications, systemic side
    effects)
  • Periocular injections
  • Severe acute anterior uveitis
  • Adjuvant to topical/systemic
  • Poor compliance
  • Pre op

29
TREATMENT
  • Systemic therapy
  • Preparations
  • Prednisolone 5mg
  • Indications
  • Rules
  • Start with large dose then reduce
  • Initial dose 1-1.5 mg/kg BW
  • Before breakfast
  • Taper off
  • Less than 2 weeks abrupt stop

30
TREATMENT
  • Side effects
  • Short term
  • Long term

31
TREATMENT
  • Cyclosporin
  • Steroid sparing agent
  • Complications are hypertension and nephrotoxicity
  • Cytotoxic drugs
  • Potentially blinding bilateral reversible uveitis
  • Intolerable side effects from systemic steroids
    therapy.
