Histopathologic findings | Clinical correspondents/Ancillary exams |
---|---|
Diffuse granulomatous inflammatory infiltrate of choroid (lymphocytes, macrophages, epithelioid cells, multinucleated giant cells) | In the acute and chronic stages: |
Creamy white lesions in deep retina/choroid | |
Diffuse choroid thickening (US, EDI-OCT) | |
Dark dots (?) (ICGA) | |
Dalen-Fuchs nodules (conglomerate between Bruch’s membrane and RPE consisting of lymphocytes, pigment-laden macrophages, epithelioid cells, and proliferated RPE) | In the acute stage: |
Focal leakage at the RPE level (?) (FA) | |
Choroidal melanocytes without melanin granules | In the convalescent stage: |
“Sunset glow fundus” (diffuse depigmentation) | |
Focal RPE atrophy with retinal and choroidal adhesion | In the convalescent stage: |
Atrophic nummular hypopigmented lesions in the mid periphery | |
Window defect in FA (OCT) | |
RPE hyperplasia | In the convalescent stage: |
Pigment clumps (OCT, FAF (?)) | |
RPE hyperplasia without melanin granules | Subretinal fibrosis (OCT) |
