Retinal angiomatous proliferation appears to be a distinct subgroup of neovascular ARMD. It may present in one of three vasogenic stages: IRN, SRN, or CNV. Whereas ICG angiography is helpful in diagnosing RAP and in documenting the stage of the neovascularized process, it is frequently difficult to determine the precise nature and location of the new vessel formation. It is important for clinicians to recognize the vasogenic potential and the associated manifestations of this peculiar form of neovascular ARMD so that a proper diagnosis can be made, and when possible, an appropriate management administered.

IMPORTANCE Polypoidal choroidal vasculopathy (PCV) is common in Asian populations, but an optimal treatment approach remains to be confirmed. OBJECTIVE To evaluate intravitreal aflibercept injection (IAI) in participants with PCV and compare IAI monotherapy with IAI plus rescue photodynamic therapy (PDT). DESIGN, SETTING, AND PARTICIPANTS This 96-week, double-masked, sham-controlled phase 3b/4 randomized clinical trial was conducted at multiple centers in Australia,

We investigated the circadian change of choroidal thickness using high-penetration optical coherence tomography in healthy volunteers. The significant diurnal change was found and the choroid was thicker at night and thinner in daytime. Fluctuations in the choroidal thickness may be related to SBP.

Patients with active VKH disease have markedly thickened choroids, possibly related not only to inflammatory infiltration but also to increased exudation. Both the choroidal thickness and the exudative retinal detachment decreased quickly with corticosteroid treatment. Enhanced depth imaging optical coherence tomography can be used to evaluate the choroidal involvement in VKH disease in the acute stages and may prove useful in the diagnosis and management of this disease noninvasively.
