MULTIPLE EVANESCENT WHITE DOT SYNDROME MEWDS • Unilateral, Young myopic women, idiopathic, Excellent prognosis • Acute unilateral VA, photopsia, scotomata/ Viral prodrome • Numerous migratory white dots (faint, PP, mid-periphery) • Foveal granularity- Pathognomonic- PERSISTENT • Mild papillitis/ vitritis/ disc oedema/ vasculitis • FFA: early punctate hyperfluorescence/ late: staining • ICG: typical multiple hypofluorescent spots throughout fundus • Hypofluorescence around optic nerve • VF: BS, disproportionate to clinical findings/ PERSISTENT • Recovery: 3-10/52, , no scarring
ACUTE POSTERIOR MULTIFOCAL PLACOID PIGMENT EPITHELIOPATHY/ APMPPE • Bilateral, young healthy adults, good prognosis • HLA-B7 ,DR2 / Influenza-like prodrome 50% • VA uni- bilateral in a few days • Creamy white placoid lesions at PP (RPE level) • Mild vitritis/ vessel sheathing/ disc oedema FFA: early: dense hypofluorescence late: staining Inactive: window defect ICG: Hypofluorescence (active+healed) Systemic microvasculopathy (Skin, kidney, CNS) Recovery: within 1/12, depigmentation and clumping
SERPIGENOUS CHOROIDOPATHY • Bilateral, chronic/ recurring, progressive, 40-60y, Poor prognosis • VA uni bilateral (asymmetric), Scotomata, Photopsiae • Active: Cream coloured,hazy borders, increasing brightness/ optic disccentrifugaly/ May start ANYWHERE/ Skip- satellite lesions/ Border inactive scars (DD APMPPE)/ Vascular predilection • Anterior uveitis/ vitritis • Inactive: choroidal atrophy (large chor. vessels) FFA: early: central hypo+ hyper rim late: hyper leaks into the lesion (spotty staining) Healed: visible large choroidal vessels CNVM No systemic associations Rx: steroids, azathioprine, cyclosporine/ laser
