Abstract Details



Purpose:

To localize the various levels of abnormalities in white dot syndromes by comparing en face optical coherence tomography (OCT) and OCT-Angiography with various conventional imaging modalities

Setting:

White dot syndromes. En face optical coherence tomography. Optical coherence tomography angiography

Methods:

In this retrospective case series, multimodal imaging was performed on 10 patients with white dot syndromes. Optical coherence tomography angiography (OCT-A) was performed at the level of the superficial and deep retinal capillary plexus and choriocapillaris. En face OCT was also performed

Results:

Three patients had punctate inner choroidopathy (PIC) with choroidal neovascularization (CNV), two patients had multiple evanescent white dot syndrome (MEWDS), two had acute posterior multifocal placoid pigment epitheliopathy (APMPPE), two had serpiginous choroiditis and one had unilateral acute idiopathic maculopathy (UAIM). MEWDS lesions were more easily detectable and localized with en face OCT. OCT-A analysis of the retinal microvasculature and choriocapillaris and choroid were unremarkable in our patients with MEWDS. OCT-A demonstrated transient inner choroidal flow changes associated with APMPPE. Dark areas were seen in the choriocapillaris layer and choroid layer of OCT-A in our patients with serpiginous choroiditis. CNV was identified in patients with PIC. The dark pattern of the choriocapillaris together with the photoreceptor outer-segment layer elevation and disruption was seen in the patient with UAIM

Conclusions:

OCT-A provides useful information of choriocapillaris and choroidal microvasculature in white dot syndromes. Our findings suggest that OCT-A and en face OCT are an important imaging modalities for managing white dot syndromes together with other diagnostic tools
