Q

Unilateral

A

MEWDS, AZOOR

26
Q

Often have vitreous cells, venous sheathing and RAPD

27
Q

Enlarged blind spot

28
Q

FA-early hyperflu in wreath-like configuration. Late staining of lesions. Windows defects after resolution

29
Q

reduced a-wave in ERG

30
Q

may start unilateral but tends to be bilateral asymmetric

31
Q

persistent and stabilizes by 6 months in most cases

32
Q

Anterior uveitis (50%)

33
Q

ERG remains normal until there is advanced retinal atrophy

34
Q

involvement is predominantly macular

35
Q

in 50% stabilization occurs within 6 months but recovery is infrequent

36
Q

EOG shows absence or severe reduction of the light rise

37
Q

ERG - a-wave and b-wave amplitude reduction

38
Q

cones tend to be affected more than rods

39
Q

often temporal

40
Q

FAF. Hyperautofluorescent spots corresponding to the macular lesions are visible during active inflammation

41
Q

Headache and other neurological symptoms are common and can commence many months after ocular disease onset

42
Q

initially at the posterior pole

43
Q

HLA-B7 and HLA-DR2

44
Q

ICGA demonstrates non-perfusion of the choriocapillaris

45
Q

M>F

A

Serpiginous

46
Q

HLA-B7

A

APMPPE (also HLA-DR2), Serpiginous

47
Q

typically starts around the optic disc and extends gradually

A

Serpiginous

48
Q

Recurrence is usually contiguous with or adjacent to existing areas, eventually resulting in extensive chorioretinal atrophy

A

Serpiginous

49
Q

Relentless placoid chorioretinitis (RPC)

A

features of both APMPPE and serpiginous choroiditis

50
Q

Persistent placoid maculopathy (PPM)

A

similar to those of the macular variant of serpiginous choroidopathy, but which generally behave in a more benign fashion unless complicated by CNV

51
Q

Vitiliginous Chorioretinitis

52
Q

varying degree of vitritis is commonly found when the disease is active

53
Q

ERG and VF are the most useful diagnostic tools

54
Q

most numerous nasal to the optic disc

55
Q

shimmering photopsias

56
Q

100-200 um concentrated around the macula

57
Q

typically does not present with vitritis

A

serpiginous, presumed ocular histoplasmosis syndrome

58
Q

hypopigmented choroidal lesions 1/4 to 1/2 optic disc diameter, clustered around the optic nerve, radiating towards the periphery

59
Q

ICG multiple hypofluorescent spots, which are typically more numerous than apparent on slit lamp

60
Q

ERG prolonged 30 Hz flicker implicit times

61
Q

diminished b waves compared to a wave
