14. FOCAL CHOROIDITIS 03 04 CENTRAL CHOROIDITIS• Involves macular area • Alone or in combination with disseminated choroiditis • Toxoplasmosis, histoplasmosis, JUXTAPAPILLARY/ JUXTACAECAL CHOROIDITIS • Area adjoining to optic disc • Jensen’s choroiditis ANTERIOR PERIPHERAL CHOROIDITIS• Multiple small patches in peripheral part of choroid(Anterior to Choroid) • Syphilitic choroiditis EQUATORIAL CHOROIDITIS • Involves choroid in equatorial region only CHARACTERISED BY SINGLE OR FEW SMALL PATCHES OF INFLAMMATION DEPENDING UPON LOCATION OF LESION 01 01 02

15. MULTIFOCAL CHOROIDITIS DISSEMINATED CHOROIDITIS Multiple but small areas of inflammation scattered over the greater part of choroid ACTIVE SYPHILIS TUBERCULOSIS OBSCURE CAUSE S 02
