  Swept-source optical coherence tomography angiography (SS-OCTA) is a promising new imaging modality for assessing retinal and choroidal vasculature. Faster scanning speed, large number of A-scan acquisition, and enhanced depth penetration has enhanced the detailed analysis of retinal layers. The authors discuss SS-OCTA features of a rare case of retinal arteriovenous malformation. Image analysis revealed the anomalous large-caliber vessels occupying up to the entire retinal thickness with associated echolucent changes in the inner retinal layers surrounding the retinal vessels, along with disruption of the outer retinal layers, including the inner/outer segments of photoreceptors beneath the large tortuous vessels outside the ...

  Background Subacute sclerosing panencephalitis (SSPE) is a potentially fatal complication of measles. The authors report a case of recurrent myoclonic jerks under investigation, whose ophthalmic examination pointed to the diagnosis. Case presentation A 12-year-old boy with recurrent episodes of myoclonic jerks was found to have optic disc pallor and an irregular macular scar with pigmentation in the left eye. The retinal finding proved to be a strong diagnostic clue for SSPE. There was a history of exanthematous fever in childhood. Antibodies against measles were detected in both the cerebrospinal fluid and serum. Retinitis with intraretinal and subretinal hemorrhage in the ...

  The authors report the use of optical coherence tomography angiography (OCTA) (DRI OCT Triton; Topcon, Tokyo, Japan) to localize, characterize, and confirm the presence of a choroidal neovascular membrane in a patient of focal choroidal excavation (FCE) with recent-onset metamorphopsia and visual blurring. En face OCTA images just above the level of the retinal pigment epithelium-Bruch's membrane complex typically showed the presence of a glomerulus-like neovascular network with an adjacent dark area suggestive of a Type 2 choroidal neovascularization (CNV). OCTA was found to be a very useful, noninvasive, and quick imaging modality to detect secondary CNV formation in ...
