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
1. Creamy white placoid lesions at PP (RPE level)
2. 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
1. Active: Cream coloured,hazy borders, increasing brightness/
optic disccentrifugaly/ May start ANYWHERE/ Skipsatellite lesions/ Border inactive scars (DD APMPPE)/
Vascular predilection
2. Anterior uveitis/ vitritis
3. 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
BIRDSHOT CHORIORETINOPATHY/ BSR
Bilateral, women, middle age, guarded prognosis
Remissions- exacerbations
HLA-A29 ( HIGHEST RR of any disease~200x)
A29.2/ S-antigen/ CD8+/ Choroid + ret. vessels
Floaters, VA- nyctalopia- photopsia-  colour vision
1. Creamy –yellow ovoid deep spots/ centrifugal/ nasalinferior retina
2. Vitritis/ vasculitis/ narrowing of vessels
3. CMO/ disc oedema
4. Chronic: well defined atrophy/ NO PIGMENT
FFA: early: normal/ ‘Quenching’ of vessels
late: leakage (intraretinal, disc)
ICG: hypo-, fuzzy choroidal vessels: Activity
Rx: steroids/ immunosuppressants
PUNCTATE INNER CHOROIDOPATHY
PIC
Bilateral, young myopic women, guarded prognosis
Scotomata/ photopsia/ Blurred vision
1. Small spots (same age),PP/ same as MCP
2. SRD
3. NO uveitis/vitritis
DD from POHS
Weeks to recover
Residual scars (with  pigment)
CNVM
MULTIFOCAL CHOROIDITIS WITH PANUVEITIS
MCP
Uni bi, myopic, women, middle age, fair prognosis
Subacute blurring/ photopsiea/ scotomata/ floaters/
photophobia/ pain
1. Multiple, deep, yellow-grey lesions
2. Vitritis (all)/ ant. uveitis 50% (DD POHS)
3. Chronic: atrophy+pigmentation
FFA: early: hypolate: fuzzy leaking
ICG: hypofl. spots- peripapillary
Recurrences (common)
CMO, Subretinal Fibrosis, CNVM
Rx: Steroids/ Imunosuppressants/ Laser
PRESUMED OCULAR HISTOPLASMOSIS SYNDROME
POHS
H. capsulatum/ Missisipi- Ohio
30-40y
Good prognosis/ 2-10% ocular lesions in endemic areas
1/1000 maculopathy
HLA DR2, HLA-B7Maculopathy
1. Histo spots (PP, midperiphery)/ linear streaks-equator
2. PPA
3. CNVM (v if macular spots)
4. Clear Vitreous, No PED
Positive skin testing/ serology/ CXR
Laser/ Surgical
