2 Iris (4)- metabolism of Ant.seg
Middle coat (Iris,Ciliary body,Choroid) Vascular Provides nutrition Iris (4)- metabolism of Ant.seg Ciliary body (Pars plicata ; Pars plana) - secrete aqueous – nutrition to avascular structures Choroid – nutrition to outer retina

3 Inflammations (Uveitis) Vascular & circulatory distyrbances
( CSR ; NVI ; UES ) Degenerative changes ( Atrophy / Iridoschisis /PDS /Myopic / ARMD ) Cong. Abnormalities ( Persistent pupillary membrane / Coloboma ) Cysts / Tumors ( Malignant melanoma )

4 UVEITIS - Classification
Based on Anatomical site 1.Anterior ( Iritis / Ant.cyclitis / Iridocyclitis ) 2.Intermidiate ( Post.cyclitis / Pars planitis ) 3.Posterior ( Choroiditis / Chorioretinitis ) Pan Uveitis ( all uveal tissue ) Based on Etiology infective / allergic/ toxic/ traumatic/ asso with sys diseases/ idiopathic. Based On Duration ( Acute / Chronic ) Based on Pathology(Granulomatous/Non-granulomatous)

5 Etiopathogenesis Etiology – 1. Infective a. Exogenous
b. Secondary infection c. Endogenous 2. Allergic(hypersensitivity linked) a. Microbial allergy b. Anaphylactic c. Atopic d. Auto immune e. HLA - associated

6 3. Toxic a. Endotoxins b. Endo ocular toxins c. Exogenous toxins 4
3. Toxic a. Endotoxins b. Endo ocular toxins c. Exogenous toxins 4. Traumatic 5. Associated with non- infective systemic diseases 6.Idiopathic

7 PATHOLOGY Supperative uveitis Non granulomatous uveitis

8 Anterior Uveitis / Iridocyclitis
Definition Etiopathogenesis Classification Clinical features Symptoms: Pain Redness Photophobia Lacrimation Diminision of Vision

9 Signs Lids –oedema Conjunctiva – CCC Cornea – oedema, KPs Anterior chamber – Flare (tyndall / brownian ), Cells / Hypopyon Changes in depth/angle Iris – Loss of pattern/colour Iris nodules (Koppe’s/Busacca’s) Synechia (posterior/anterior) Pupil - irregular , <reaction,Seclusio/Occlusio Pupillae Lens – Pigment.on ALC / Complicated cataracts Anterior Vitreous - cells

10 KPs Keratic precipitates
Proteinaceous cellular deposits on endotheliun of cornea Arranged in traingle ( Artls) Severity/duration/type of uveitis Fine KPs –small/nongranulomatous/lymphocutes/numerous/acute Mutton fat KPs – large,waxy/granulomatous/chronic/epitheloid&macrophages/fewer Old KPs - pigmented kPs/Groundglass appearence

13 Koppe’s Busacca’s

14 Festooned pupil

15 Complications Complicated cataracts
Secondary Glaucomas ( Early /Late ) Cyclitic memebrane Choroiditis Band-shaped keratopathy Pthisis bulbi

16 DD(Differential Diagnosis) of RED EYE
Acute Conjunctivitis Acute irido cyclitis Acute Congestive Glaucoma

17 Differentiating features of red eye
Acute acute acute conjun irido cong gla Onset Pain Discharge Coloured halos Vision Congestion Tenderness Pupil Media AC Iris IOP Constitutional sym

18 Investigations Heamatological – TLC , DLC & ESR RBS, bl uric acid
Serological tests Other tests Urine examination Stool examination Radiological Skin tests

19 Treatment Non specific Rx – Local Rx Corticosteroids
( Topical / Sub-conjunctival/ Sub-tenons ) Cycloplegics (Atropine/Cyclopentolate/Homide) Systemic Rx Cortico steroids NSAIDs Immuno-suppressives Hot applications Specific Rx for underlying Cause Rx of complications

20 ENDOPHTHALMITIS Definition : Inflammation of endo cavities of eyeball (Anterior chamber & Vitreous ) With uveal tissue Etiopathogenesis: Infective : Exogenous/Endogenous/sec Non-infective(sterile): . Post operative .post traumatic .intra ocular tumor .phacoanaphylactic Clinical features: Symptoms : Cardinal features Pain / Swelling of lid / < vision

21 Signs: Lid-oedema Conjunctiva – congestion/chemosis
Cornea – Odema/Infiltrates Anterior chamber – Exudates/Hypopyon Iris – oedematous/muddy Pupil – yellow reflex(amaurotic cat’s eye) due to exudates in vitreous IOP-

22 Endoph.- Organisms Gram +ve Gram -ve
Pseudomonas- 8% Proteus- 5% Haemophilus influenza-0-1% Klebsiella Staph. Epidermidis-43% Streptococcus-20% Staph. Aureus- 15% Propionibacterium Bacillus cereus 1%

23 Treatment Intra Vitreal AB & diagnostic tap Topical /Systemic AB
Steroid therapy Supportive therapy Vitrectomy Enucleation ( End Stage)

24 Clinical management - suspected endophthalmitis
Aq. And vitreous biopsy Inject intravitreal AB Obtain C/S report Consider vitrectomy No improvement Repeat intravit. Inj.( Abs indicated by C & S reports) Clinically worsening

25 Intravitreal antibiotics
Combination of 2 drugs to cover G+ and G- organisms Gentamicin (G-) + Cefazoline (G+) Vancomycin (G+) + Amikacin (G-) Vancomycin (G+) + Ceftazidime (G-)

26 Vitrectomy in Endophthalmitis
“Core” vitrectomy Periphery not attacked “½ vit. Volume” removed No attempt at vit. Separation Low suction Endo. Phc - if needed for ret. Tears Fluid - gas exchange

27 Endophthalmitis Patient Personnel Environment Endophthalmitis
Instruments Personnel

28 Panophthalmitis Definition: Inflammation of cavities of eyeball with all coats of eyeball Endopthalmitis + outer coat involvement Etiopathogenesis- Clinicalfeatures – All C/F of endoph + Proptosis , Painful limitation of movements,Near total loss of vision Compl’ : (Orbital cellulitis / Cavernous sinus thrombosis/meningitis) Management – Systemic ABs & Eviseration

29 MALIGNANT MELANOMA OF CHOROID
Most common / adults / 40 to 70yrs / unilateral. Neural crest derived pigment cells. Pathology : pre-existing nevus cells / denovo gross – two forms – circumscribed diffuse Histo pathology : 4 types (modified CALLENDERS) 1. spindle cell type 2. epitheloid cell type 3. mixed cell type 4. necrotic type

30

31 3. stage of extra ocular extention 4. stage of distant metastasis
C/ P : 4 stages 1. Quiescent stage – small / large 2. Glaucomatous stage 3. stage of extra ocular extention 4. stage of distant metastasis

32

33

34 naevus,melanocytoma,hyperplasia of pigment epithelium.
D/D : Quiescent stage – without RD naevus,melanocytoma,hyperplasia of pigment epithelium. - with RD – simple RD, choroidal hemangioma & secondary deposits. Glaucomatous stage -

35 Transillumination test USG FFA Radio active tracer MRI
INVESTIGATIONS : Indirect ophthalmoscopy Transillumination test USG FFA Radio active tracer MRI

36

37 Treatment : 1.conservative - Brachytherapy <10mm in elevation
<20mm diameter - External beam radiotherapy - Trans pupillary thermotherapy(TTT) - Trans scleral local resection - Steriostatic radio surgery 2. enucleation 3. exenteration or debulking 4. palliative
