    1. Retinal Arteriovenous Malformation Assessment Using Swept-Source OCT Angiography

      Retinal Arteriovenous Malformation Assessment Using Swept-Source OCT Angiography

      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 ...

    2. Utility of microscope-integrated optical coherence tomography (MIOCT) in the treatment of myopic macular hole retinal detachment

      Utility of microscope-integrated optical coherence tomography (MIOCT) in the treatment of myopic macular hole retinal detachment

      Macular hole-associated retinal detachment in high myopia is described as a final stage in progression of myopic traction maculopathy (MTM). 1–3 Shimada et al 4 described the progressive stages of MTM from macular retinoschisis to serous retinal detachment in high myopia. Stage 4 MTM is characterised as disappearance of retinoschisis with progression to retinal detachment due to macular hole formation. It is hypothesised that vitreoschisis and abnormal vitreo-retinal interface create the premacular tangential traction. 5 6 Intraoperative triamcinolone acetonide is used to visualise the residual posterior vitreous cortex (PVC). We hereby describe the utility of microscope-integrated optical coherence tomography ...
