Uveitis

Dr. Mervat El-Shabrawy

Associate Prof. of Ophthalmology, FOM, SCU

slide2
Def. :

- Inflammation of the uveal tract.

  • Classifications: The 4 most useful classifications are :-

(1) Anatomical :

Anterior

Uveitis

Intermediate

uveitis

Posterior

uveitis

Diffuse

uveitis

Iritis

Iridocyclitis

slide3
Cont.

(2) Clinical :

(3) Etiological :

(4) Pathological :

Acute

Chronic

Exogenous

Endogenous

Granulomatous

Non-Granulomatous

irido cyclitis
Irido-cyclitis
  • Def. :

- Inflammation of the iris & ciliary body.

  • Etiology :

A- Primary:

Syndromes of

Unknown etiology

Infection:

Allergy

Constitutional

Exogenous

Bacterial

Behcet’s

Endogenous

Non-bacterial

Vogt-Koyanagi-Harada

slide5
N.B.
  • Behcet syndrom:

- Oral ulcerations.

- Genital ulcerations.

- Uveitis.

  • Vogt-Koyanagi-Harada syndrom:

- Alopecia.

- Poliosis.

- Vetiligo.

- Uveitis

slide6
B- Secondary :

Cornea

Sclera

Lens

Retina

I.O. tumors

I.O.F.B

R.D.

Keratitis

Scleritis

Subluxation

Or

Dislocation

pathology 3 phases
Pathology: 3 phases:

1)Vascular Phase:

- Dilatation & congestion of the blood vessels to bring more leucocytes.

2) Exudative Phase:

- Exudation of inflamm. Fluids from dilated vessels.

* The result of this exudation:

a- Iris & ciliary body:-Edema of iris & C.B.

- Loss of iris pattern

- Pressure on the nerves

- Spasm of ciliary muscles

slide8
b- Outside iris & C.B. :

- Aquous flare.

- Collection of exudates in: Angle, pupil, between iris & lens and behind lens.

3) Cellular Phase:

- Keratic Precipitate (KPs): active & passive.

- Lenticular Precipitates (LPs):

- Vitrous opacities, Vitritis

clinical picture usually recurrent
Clinical Picture:usually recurrent.
  • Symptoms:

1) Pain: Dull aching.

Why???

-Nerves: Stretch & irritation of nerve ending.

- Muscles: Spam of intrinsic muscles & C.M.

- Glaucoma: Secondary.

slide10
Cont.

Reflex irritation of the

5th N. endings

2) Photophobia:

3) Lacrimation:

4) Blepharospasm:

5) Diminution of vision:

Why???

-Corneal edema.

- Aquous flare.

- Pupillary memb.

- Vitritis

- Toxic maculopathy.

- Hazziness of the lens.

2- Photophobia

3- Lacrimation

4- Blepharospasm

5- Diminution of vision

6- Redness of the eye

slide12
Cont.
  • Signs:

1) Lid: Edema.

2) Conjunctiva: Conj. & ciliary injections.

3) Cornea: Edema & KPs.

4) Iris: Muddy.

5) Ciliarry body: Tender.

6) Anterior chamber:- Aquous flare.

- Hypopon.

- Hyphaema.

7) Pupil:- Constricted.

- Irregular.

- Sluggish reaction.

8) Lens:- Iris pigment on the capsule (LPs).

9) Intra ocular pressure: raised, 2ry glaucoma.

10) Vitrous:Vitritis.

11) Macula:Toxic maculopathy.

complications
Complications:

1) Cornea: Deep keratitis.

2) Iris:- Post Synaechia.

- Atrophy “late”

3) Angle: P.A.S.

4) Lens: Cataract.

5) Cyclitic memb.

6) Secondary glaucoma.

7) Retinitis, optic neuritis & toxic maculopathy.

8) Endophthalmitis or Panophthalmitisin sever cases

investigations
Investigations:

Clinically

Radiologically

Laboratory

treatment
Treatment

(1) Local:

a) Atropine:- Internal eye rest.

- Relaxation of the C.M.

- Breaking fresh synaechia & dec. formation.

b) Cortisone:- Anti-inflammatory.

- Anti-Allergic.

- Fibrinolytic.

c) Hot Fomentation.

d) Dark Glasses.

slide19
(2) General:

a) Systemic cortisone:in sever cases.

b) Systemic broad spectrum A.B.s.

c) Analgesics & anti-inflammatory drugs.

- In sever resistant cases -

d) Cytotoxic drugs.

e) Immunosuppressive drugs.

(3) Causal TTT:

(4) TTT of complications:

posterior uveitis choroiditis
Posterior Uveitis- Choroiditis -
  • Def. :
