IDIOPATHIC SPECIFIC UVEITIS SYNDROMES 1. Fuchs uveitis syndrome 2. Intermediate uveitis 3. Juvenile chronic iridocyclitis 4. Acute anterior uveitis in young adults 5. Sympathetic ophthalmitis
Signs of Fuchs uveitis syndrome • Unilateral, chronic anterior uveitis • Resistant to therapy • No posterior synechiae • KP - small and scattered • throughout endothelium • Diffuse iris stromal atrophy • Feathery fibrin filaments • Occasionally iris nodules • Heterochromia iridis - • Iris retroillumination affected eye is usually hypochromic
Complications of Fuchs uveitis syndrome Cataract Angle new vessels Glaucoma Uncommon but control may be difficult Very common and frequently presenting feature May bleed during surgery
Intermediate uveitis • Typically affects children and young adults • Insidious and chronic • Frequently bilateral but asymmetrical • Usually presents with floaters Vitritis Vitreous snowballs Snowbanking in pars planitis Mild peripheral periphlebitis
Intermediate uveitis Cystoid macular oedema Treatment Posterior sub-Tenon steroids if poor VA
Juvenile chronic iridocyclitis • Majority are girls • Initially no systemic disease • Minority subsequently develop arthritis Progression of complications Posterior synechiae Band keratopathy Cataract
Acute anterior uveitis in young adults • Majority are men • 45% are positive for HLA-B27 • Initially no systemic disease • Minority subsequently develop ankylosing spondylitis Fibrinous exudate Residual pigment on lens
Sympathetic ophthalmitis Bilateral granulomatous panuveitis Typically follows penetrating trauma Granulomatous anterior uveitis Multifocal choroiditis
