4. Uveitis is a sight threatening disorder, and may be
associated with life threatening diseases.
Uveitis can be caused by various ocular or systemic
infectious, immunological, and malignant diseases.
5. Classification:
• Anatomical:
- Anterior uveitis 75% : inflammation of
the iris (iritis), and anterior part of the
ciliary body (iridocyclitis).
- Intermediate uveitis: inflammation of
the ciliary body (cyclitis, pars
planatis).
- Posterior uveitis : inflammation
behind ora serrata; inflammation of
the choroid and retina (choroiditis,
retinitis, chorio-retinitis, retinal
vasculitis).
- Pan uveitis: inflammation of the entire
uveal tract.
6. • Clinical:
- Acute: sudden, short duration
- Chronic: insidious, long duration,
sometimes with exacerbation and remission
- Recurrent: repeated episodes of uveitis
separated by periods of inactivity without
treatment.
7. • Pathological classification:
• suppurative / purulent -polymorphonuclear cells
,purulent exudates.
• Staphylococcus strepto,pneumo.gonococci
• Non suppurative
Non granulomatous - blood aqueous barrier break
down due to physical and toxic insult
- fibrinous exudate,lymphocytes,macrophages,plasma
cells.
-
8. • Small and medium sized fine kps seen in non
granulomatous.
9. Granulomatous uveitis:
• Chronic inflammation,proliferation in nature.
• Nonpyogenic,non virulent,inorganic or
organic,haemorrhage,necrotic tissue.
• Tb,leprosy,syphilis,brucellosis,leptospira,viral,protoz
oal.
10. • Infiltration of lymphocyte,proliferation of large
mononuclear epitheloid and giant cells aggregates to
iris nodules,mutton fat kps.
15. Anterior uveitis
Signs
- Reduced visual acuity (V.A.)
- Circum-corneal congestion
- Cornea: Keratic precipitate. KP: (aggregation of inflammatory cells
on the posterior surface of the endothelium)
small , endothelium dusting (non-granulomatous uveitis)
Large (muttan fat) (chronic, granulomatous uveitis)
- Ant. Chamber: cells and flare ( increase protein in the aqueous)
hypopyon (aggregation of inflammatory cells at the
bottom of anterior chamber with fluid level)
- Pupil: Miosed (constricted)
Irregular, posterior synechiae (adhesion between the iris and the lens),
- Iris: Rubeosis ( iris neo-vascularization).
Iris atrophy (chronic)
Iris nodules and granuloma (chronic, granulomatous uveitis)
- Intra-ocular pressure (IOP): may be normal, elevated or
depressed
18. Signs
-Cornea:
Keratic precipitate. KP:
aggregation of inflammatory cells on the posterior
surface of the endothelium)
Small , endothelium dusting
(non-granulomatous uveitis)
Large (muttan fat) (chronic,
granulomatous uveitis)
Band keratopathy: deposition of calcium at
Bowmann’s layer
19. Signs
-Ant. Chamber:
- cells
-flare ( increase protein in the aqueous)
-hypopyon (aggregation ofinflammatory
cells at the bottom of anterior
chamber with fluid level)
23. Ankylosing Spondylitits
Young adults
Male are affected more
Arthritis; axial skeleton
-sacroiliac joint and
intervertebral joints
90% positive HLA-B27
Acute, Recurrent,
non-granulomatous Anterior Uveitis
24. Juvenile idiopathic arthritis
Idiopathic,
Chronic arthritis
Age under16 years. Females are affected more commonly
Pauciarticular type (less than 5 joints are involved)
seronegative (for R.F.),
80% positive for ANA
Bilateral, Chronic, non-granulomatous Ant. Uveitis
painless,
Complications:
1- Cataract
2- Band keratopathy
.
30. - Posterior uveitis: inflammation behind
ora serrata, inflammation of the
choroid and retina (choroiditis,
retinitis, chorio-retinitis, retinal
vasculitis).
.
31. Posterior Uveitis
• Symptoms
- Floaters (moving shadows in the field of
vision caused by vitreous opacities)
- Blurring of vision
32. Posterior uveitis
Signs:
• Vitreous: cells, flare and opacities
• fundus lesions may be focal, multi-focal, or geographical lesions
-Choroiditis; yellow, well demarcated patches
-Retinitis; white cloudy patches with indistinct margins
-Old inactive lesion appears as white well defined area of
chorio- retinal atrophy with pigmented borders
-Vasculitis; fluffy haziness surrounding blood columns
vascular sheathening
33. Toxoplasmosis
• Toxoplasma gondii is an obligatory,
intracellular protozoan parasite
Acquired, congenital
- Vitritis.
- Retinitis;
Active lesion: creamy-white lesion with
indistinct margins
Inactive lesion: white well defined area of
chorio- retinal atrophy with pigmented
borders
36. Pan uveitis
• Idiopathic, multisystem disease
characterized by recurrent episodes of
orogenital ulceration and vasculitis
37. Behcet syndrome
• Diagnosis:
• 1 Recurrent oral ulceration characterized by painful minor or major aphthous
lesions that have recurred at least three times in a 12-month period.
2 Plus at least two of the following:
• Recurrent genital ulceration
• Ocular inflammation.
• Skin lesions include erythema nodosum, folliculitis, acneiform nodules
• Positive pathergy test, cutaneous hypersensitivity, which is characterized by the
formation of a pustule after 24–48 hours at the site of a sterile needle prick
40. Pan uveitis
Vogt Koyanagi Harada (VKH)
Multi-systemic auto-immune disorder affect pigmented
cells in the body.
Involves CNS, eyes, and skin
41. Vogt Koyanagi Harada (VKH)
- Neurological and auditory manifestations
Headache, Tinnitus
- Integumentary findings, not preceding onset of
central nervous system or ocular disease, such as
alopecia, poliosis and vitiligo
42. Vogt Koyanagi Harada (VKH)
- Bilateral uveitis
Acute stage:
Multifocal serous detachment of
sensory retina
Bilateral exudative retinal detachment
Chronic stage:
Depigmentation of the fundus; Vitilligo
of the fundus
Dalen Fuchs atrophic spots
43. Presumed Tuberculous Uveitis
According to WHO:
About one third of the world's population, are infected by tuberculosis
10% of infected people are symptomatic
90% have latent TB
TB is endemic in Iraq
TB uveitis develops following hematogenous spread from a
primary latent focus and usually occurs without evidence of
systemic TB.
46. Management of Uveitis:
1- Investigations: Aimed for determining the etiology.
Indications: chronic, recurrent, and granulomatous anterior uveitis
Intermidiate, posterior and pan-uveitis
2-Steriods:
Topical, Side effects of corticosteroids eye-drops:
• Flare up of pre-existing eye infection
• Predispose for microbial keratitis, e.g. viral keratitis.
• Inhibit collagen synthesis of the cornea, and predispose for corneal thinning
• Cataract (chronic use)
• Open angle glaucoma (chronic use)
Periocular injections of steroids; used in severe ant. , Intermidiate, posterior uveitis
Systemic steroids; used in; severe anterior, Intermidiate uveitis, posterior uveitis
3- Mydriatics: -decrease pain by relieve ciliary muscles spasm
- prevent synechiae, break down synechiae
4- Anti-microbial drugs: in infectious types; Toxoplasmosis, Presumed TB uveitis.
5- Immunomodulator and/or Immunoppressive agents:
In bilateral, severe , vision threatening , steroid sparing, non-infectious
-Cyclosporin; T-cell immunosuppressive agent
-Methotrexate
- Azathioprine
