R/O ARPE(OD) - Acute Retinal Pigment Epithelitis
R/O MEWDS(OD) - Multiple Evanescent White Dot Syndrome
R/O PIC(OD) - Punctate inner choroidopathy
Diagnostic plan
FAG(OD  OS)
VF 24-2
F/U 2 days later
Initial plan
Difficult to DDx.
<White dot synd.> -> exclusion diagnosis
MEWS - u/l, multiple, hypofluorescent lesions in ICG
PIC – b/l, may represent an autoimmune type of uveitis
The dot appears as a small granuloma which is composed of lymphocytes and macrophages.

9. VF24-2

10. FAG & ICG(OD) – early phase
FAG transmission hyperfluorescence(WD)
At the midphase of ICGA, a foveolar
patchy hyperfluorescence, which slowly faded, was
observed.
On ICGA midframe to late frame, a central
halolike hyperfluorescence, giving a cockadelike
appearance to the macular area, was seen.

11. FAG & ICG(OD) – late phase
FAG transmission hyperfluorescence(WD)
Generally FAG : mild stain(OD) / ICG : no NV
At the midphase of ICGA, a foveolar
patchy hyperfluorescence, which slowly faded, was
observed.
On ICGA midframe to late frame, a central
halolike hyperfluorescence, giving a cockadelike
appearance to the macular area, was seen.

14. Case Review ‘ACUTE RETINAL PIGMENT EPITHELIITIS’ (ARPE)

15. ACUTE RETINAL PIGMENT EPITHELITIS(ARPE) - Introduction
First described in 1972 by Krill and Deutman
a rare macular disorder affecting healthy young adults
acute, painless, unilateral ‘blurred vision’
or ‘central scotoma’

16. Anatomy(10 Retinal layers)

17. Interpretation of Spectral Domain OCT

18. Natural course of ARPE Self-limited
almost all patients regaining good visual acuity within 6 to 12 weeks
Recurrence is unusual

19. Inflammation on and around RPE !?
Pathogenesis
Inflammation on and around RPE !?
Unknown
May be an inflammatory disorder of the RPE
Transient dysfunction in the RPE/photoreceptor outer segments interface
Not been associated with any systemic conditions.
cf.) preceding viral illness has been reported
the foveal photoreceptors may be the primary site affected in ARPE, with a secondary
postinflammatory response in the RPE.

20. Pathogenesis of ARPE Initial lesion? RPE vs outer neurosensory retina
(with a secondary subacute post- inflammatory response in the RPE)
increased reflectivity at IS/OS interface
the RPE inner band
is disrupted
a disruption of the IS/OS interface associated with a wider
disruption of the RPE inner band
The RPE inner band is considered to correspond either to
the Verhoeff’s membrane constituted by tight junctions
of RPE cells or to basal infoldings and apical processes
that enclose the photoreceptor outer segments

21. Diagnostic clues
the presence of a characteristic fine pigment stippling in the macular area
at the level of the retinal pigment epithelium(RPE)
surrounded by yellow-white haloes of hypopigmentation
At the midphase of ICGA, a foveolar
patchy hyperfluorescence, which slowly faded, was
observed. On ICGA midframe to late frame, a central
halolike hyperfluorescence, giving a cockadelike
appearance to the macular area, was seen.

22. Discrete area of pigment stippling associated with a foveolar yellowish hypopigmented lesion
Fundus photography
Fundus photograph demonstrating
a discrete area of pigment stippling associated with a
foveolar yellowish hypopigmented lesion.

23. Angiographic findings(ICG)
At the mid-frame, Foveolar patchy hyperfluorescence From Mid to late frame, Central halo-like hyperfluorescence ; Cockadelike app. to the macular area (At the late-frame, ) numerous hyperfluorescent spots of RPE staining scattered throughout the posterior pole and mid-periphery
Indocyanine green angiography(4 and 16 minutes) showing
a patchy hyperfluorescence in the macular area.
A hyperfluorescent macular halo with a cockadelike
appearance of the macula is also seen.
The intermediate and late hyperfluorescence observed
with ICGA, and the associated normal choroidal vasculature,
suggest that the RPE may always be involved in ARPE.
Indeed, the described hyperfluorescence appears to be related to RPE staining with
indocyanine green accumulation within the inflamed RPE cells

24. Angiographic findings(FAG)
Transmission hyperfluorescence
(FAG 3 min)
‘transmission hyperfluorescence’
corresponding to the hypopigmented yellowish macular lesions. This hyperfluorescence
was observed in a part of and not in the whole area of the hypopigmented area.
No leakage of dye into the surrounding retinal tissue was observed in any phase of examination.

25. Management Prognosis Observation
F/U imaging studies to confirm the diagnosis
Prognosis
Excellent
치료는 일반적인 AMD의 치료를 유지하는 것이 현재의 방침입니다.
