Undetectable Macular Neovascularization on OCT Angiography in Age Related Macular Degeneration: Comparison between Different Devices.

: The aim of this study was to report the characteristics of macular neovascularization (MNV) with undetectable flow on optical coherence tomography angiography (OCTA) in neovascular age related macular degeneration (nAMD), and compare them with the characteristics of detectable MNV. : Patients with a diagnosis of nAMD who underwent dye imaging and OCTA in the same day were included and divided into two groups: undetectable and detectable flow on OCTA. Three OCTA devices were used, two with spectral-domain technology (AngioVue, RTVue 100xAvanti, Optovue, Freemont, CA, USA and Heidelberg OCT2 Beta Angiography Module, Heidelberg Engineering, Germany) and one swept-source OCTA (PlexElite 9000; Carl Zeiss Meditec, Inc.

Swept-Source OCTA Imaging of a Presumed Solitary Circumscribed Retinal Astrocytic Proliferation.

Presumed solitary circumscribed retinal astrocytic proliferation (pSCRAP) is a rare, benign retinal tumor, typically presenting as a yellow-white, well-defined lesion. It was first qualified as astrocytic, but thanks to the development of optical coherence tomography (OCT), the lesion was identified as a deep glial lesion, as the nerve fiber layer appeared to be spared. Herein, the authors report the case of a 90-year-old man with inferopapillary pSCRAP who benefited from swept-source OCT angiography images.

Non-neovascular age-related macular degeneration with subretinal fluid.

Purpose: To evaluate the various patterns of subretinal fluid (SRF) in eyes with age-related macular degeneration (AMD) in the absence of macular neovascularisation (MNV) and to assess the long-term outcomes in these eyes.

Methods: This retrospective study included only eyes with non-neovascular AMD and associated SRF. Eyes with evidence of MNV were excluded.

Optical coherence tomography angiography findings of choroidal neovascularization secondary to laser injury: A case report.

Purpose: To report a case of choroidal neovascularization (CNV) secondary to laser injury imaged by optical coherence tomography angiography (OCTA) and treated by intravitreal anti-vascular endothelial growth factor (VEGF).

Observations: A 14-year-old boy presented with vision loss and central scotoma in the right eye (RE) in the last month, after having stared at the beam of a laser pointer. At presentation, his best-corrected visual acuity (BCVA) in the RE was 20/40 and spectral-domain OCT (SD-OCT) showed an interruption of ellipsoid zone and the presence of an hyperrelfective lesion in subfoveal region.
