4 Principles of treatment similar despite diverse aetiologies treat infectious uveitis with specific antimicrobial therapy + judicious use of corticosteroids & IMT therapy depends on presence cause & severity of a threat to vision specific therapy for non inflammatory complications treat inflammatory visual loss with antiinflammatory drugs

5 Inflammatory causes of vision loss cystoid macular oedema ischaemic retinal vasculitis progressive retinitis/ choroiditis optic neuropathy vitritis severe anterior uveitis Systemic Therapy for Uveitis

6 Principles of treatment topical corticosteroid therapy controls most anterior uveitis CME in > 40% of patients with posterior uveitis CME is a common driver of ocular therapy - usually treat unilateral CME locally - typically treat bilateral disease with systemic therapy - often combine local & systemic therapy (up to 60% in MUST)

7 Local Therapy topical: steroids, NSAIDs, CAIs periocular steroids intravitreal: steroids, avastin, methotrexate, infliximab, sustained release: retisert, ozudex Surgery vitrectomy Systemic Therapy NSAIDs corticoseroids immunosuppressives: methotrexate, cyclosporine, mycophenolate, azathioprine, cyclophosphamide biologics: anti-tnfs, anti-il2, anti-il17, anti-il6, anakinra, anti- CD20, interferons

8 Systemic Therapy systemic steroids gold standard therapy for CME & vision threatening ocular inflammation usually for bilateral disease need sufficient therapy to control inflammation & CME rapid response with high dose steroids, then combination immunotherapy in longer term minimum 6-36 month commitment to therapy

9 Drug Selection Systemic Therapy for Uveitis IMT immunomodulatory therapy - corticosteroids + immunosuppressive drug steroid sparing drugs must get steroids to a safe maintenance dose at least < 7.5mgs per day, preferably 5mgs/day or zero evidence that all steroid sparing drugs effective some drugs more effective for eye disease - methotrexate - mycophenolate

10 commonly used drugs methotrexate mycophenolate azathioprine uncommonly used drugs cyclosporine tacrolimus cyclophosphamide dapsone sulphasalazine biologics interferon 2a monoclonal antibodies - anti-tnf - anti-cd20 - others: anti-il1β, IL6, IL17, IL2, IL12/23, CD52 IVIG

35 VISUAL I & II: drug safety > 10 years of adalimumab use in other diseases side effects: - injection site reactions - infection no new safety signals esp malignancy & infection must exclude latent TB intermediate uveitis: must have MRI to exclude demyelinating disorder

36 Biologics for eye disease: early Sydney experience Behcet s 6 interferon 1 poor responder JIA uveitis 11 adalimumab 8 infliximab 3 3 poor responders => multiple TNFs + IL-6 SpA + RAAU/CAU 13 adalimumab 1 poor responder => multiple TNFs sarcoid uveitis 2 adalimumab scleritis 3 adalimumab 1 infliximab 1 rituximab 1 36

40 The challenge TNF blockers are very useful therapy for patients with vision threatening uveitis often challenging co-morbidities Ophthalmologists do not have the skills to manage patients on TNF blockers in isolation significant potential for systemic complications will require new team management paradigm 40

41 Who does what: The team approach Ophthalmologist Physician Is it working? I/S Drug is it causing side effects?

42 The challenge when are biologics contra-indicated???? - infective uveitis - demyelinating disease - infective co-morbidities what are the risks????? - infection - latent TB - demyelinating disease in IU patients - non lethal malignancy 42

43 Emerging Treatment Paradigm relapse relapse systemic steroids + methotrexate / mycophenolate / azathioprine aim to taper & stop oral steroids change to / add biologic consider local therapy + systemic therapy No one should go blind without a dose of intravitreal triamcinolone 43

44 Take Home Messages: long term commitment by both patient and ophthalmologist get help team approach for systemic therapy defining role of biologics about to start biologics revolution in uveitis
