Comparison of OCT angiography and indocyanine green angiographic findings with subtypes of polypoidal choroidal vasculopathy

Abstract

Polyps of type 1 PCV were more difficult to detect with OCTA than those of type 2 PCV. Polyps of type 1 PCV were located just beneath the RPE. The BVNs of type 1 PCV were located between the RPE and Bruch's membrane.

Presenting characteristics and prevalence of polypoidal choroidal vasculopathy in Scandinavian patients with treatment‐naïve exudative age‐related macular degeneration

“…To overcome some of these issues, current studies are investigating the applicability of OCT angiography as a supporting or a substituting modality for PCV diagnosis (Tanaka et al 2017). One important limitation is the retrospective design of this study.…”

“…From a clinical and practical point of view, ICGA requires that the patient can tolerate indocyanine green and that the clinic has facilities/income that allows ICGA to be performed. To overcome some of these issues, current studies are investigating the applicability of OCT angiography as a supporting or a substituting modality for PCV diagnosis (Tanaka et al 2017). However, given the predominantly extramacular location of PCV in Caucasians that we find in this study and that OCT angiography at this point only provide information on a pre-specified limited field of view, and due to studies demonstrating varying experiences; we believe that it may be premature yet to fully substitute ICGA and are looking forward to future studies on this matter.…”

Optical Coherence Tomography Microangiography Imaging of Circumscribed Choroidal Hemangioma

“…12 It may be particularly helpful in providing detailed angiographic imaging of vascular choroidal lesions. 13,14 To our knowledge, this is the first description of OCTA findings in a choroidal hemangioma. We find OCTA to be particularly useful in evaluating the tumor boundaries and the vascular filling pattern, particularly in comparison to ICGA.…”

Future clinical applicability of optical coherence tomography angiography

“…Perhaps the most immediate clinical application of OCT‐A is in the detection and management of choroidal neovascularisation (Figure ). Based on the anatomical location of new vessel growth – either below the retinal pigmented epithelium layer (type 1 or occult choroidal neovascularisation); between the retinal pigmented epithelium layer and the retina (type 2 or classic choroidal neovascularisation); or starting within the retina and anastomosing with the choroidal circulation (type 3 or retinal angiomatous proliferation) – all subtypes of choroidal neovascularisation can be detected with OCT‐A …”
