    1. An en face swept source optical coherence tomography study of the vitreous in eyes with anterior uveitis

      An en face swept source optical coherence tomography study of the vitreous in eyes with anterior uveitis

      Purpose: To analyse vitreous anatomy patients with anterior uveitis (AU) using swept source optical coherence tomography (SS-OCT). Methods: Patients with newly diagnosed AU and healthy participants were scanned using 16-mm SS-OCT B-scans and 12 × 12 mm cube centred at the fovea. Linear SS-OCT scans were evaluated to identify the premacular bursa (PB) above the macula and the Cloquet's canal above the optic disc. A dynamic evaluation of the 12 × 12 mm cube enabled en face measurement of the vertical and horizontal diameters of the PB and the presence/absence of communication between the PB and Cloquet's canal. Results ...

    2. Optical Coherence Tomography Angiography Findings of Iris Ischemia and Reperfusion in Cytomegalovirus Panuveitis

      Optical Coherence Tomography Angiography Findings of Iris Ischemia and Reperfusion in Cytomegalovirus Panuveitis

      Purpose : To report a case of iris ischemia in an eye affected by Cytomegalovirus (CMV)-related Chronic Retinal Necrosis (CRN) with partial reperfusion after antiviral therapy demonstrated by optical coherence tomography angiography (OCTA). Methods : Retrospective case report. Multimodal imaging was performed at each follow-up visits. Results : At baseline, the clinical findings and PCR on aqueous confirmed the diagnosis of CMV-induced CRN, while OCTA and Fluorescein Angiography showed multi-sectoral retinal and iris non-perfusion. After three weekly intravitreal injections of Foscarnet and retinal photocoagulation, the clinical and angiographic picture improved, with partial reperfusion of both retinal and iris vasculature. Conclusion : Retinal and ...

    3. Comparison between Widefield Optical Coherence Tomography Devices in Eyes with High Myopia

      Comparison between Widefield Optical Coherence Tomography Devices in Eyes with High Myopia

      Background: To compare four different optical coherence tomography (OCT) devices for visualization of retinal and subretinal layers in highly myopic eyes. Methods: In this prospective, observational, cross-sectional study, consecutive patients with high myopia and control subjects were imaged by four OCT devices: Spectralis OCT2, PlexElite 2.0 100 kHz, PlexElite 2.0 200 kHz and the Canon Xephilio OCT-S1. The acquisition protocol for comparison consisted of single vertical and horizontal line scans centered on the fovea. Comparison between the devices in the extent of visible retina, presence of conjugate image or mirror artifacts, visibility of the sclerochoroidal interface and retrobulbar ...

    4. Optical coherence tomography features of the repair tissue following RPE tear and their correlation with visual outcomes

      Optical coherence tomography features of the repair tissue following RPE tear and their correlation with visual outcomes

      To assess the optical coherence tomography (OCT) features of the repair tissue after retinal pigment epithelial (RPE) tear in neovascular age-related macular degeneration. Retrospective, observational study. Medical and imaging records of patients that developed tears after starting anti-VEGF treatment and with at least 12 months of follow-up were reviewed. OCT reflectivity of the RPE-subretinal hyperreflective tissue (SHT) complex was measured at 6, 12 and 18 months (when available). Reflectivity of the adjacent unaffected RPE-Bruch's membrane was taken as internal reference. Other variables: grade and rip occurrence (early/late); number of intravitreal injections; type of macular neovascularization; sub-macular hemorrhage (SMH ...

    5. Comparison and Repeatability of High Resolution and High Speed Scans from Spectralis Optical Coherence Tomography Angiography

      Comparison and Repeatability of High Resolution and High Speed Scans from Spectralis Optical Coherence Tomography Angiography

      Purpose : The purpose of this study was to evaluate and compare the repeatability of optical coherence tomography angiography (OCTA) derived retinal vascular quantitative metrics using high resolution (HR) versus high speed (HS) acquisition modes. Methods : Macular 4.4 × 2.9-mm OCTA images from normal, healthy volunteers were captured using both HR (768 A-scans × 256 B-scans) and HS (384 A-scans × 256 B-scans) acquisition protocols. Vessel density and vessel length density of the superficial capillary plexus and deep capillary plexus, as well as choriocapillaris flow deficit were computed. In a subset of eyes, the OCTA scans were repeated twice 2 days later ...

    6. Microaneurysms visualisation using five different optical coherence tomography angiography devices compared to fluorescein angiography

      Microaneurysms visualisation using five different optical coherence tomography angiography devices compared to fluorescein angiography

      Background To compare fluorescein angiography (FA) and five different optical coherence tomography angiography (OCTA) devices and to test their reproducibility in the evaluation of retinal microaneurysms (MAs) secondary to diabetic retinopathy (DR). Methods On the same day, patients with DR were imaged with FA and five OCTA devices: prototype Spectralis OCTA, prototype PlexElite, RTVue XR Avanti, AngioPlex and DRI OCT Triton. For all OCTA devices, a 3×3 volume scan pattern was performed. MAs were evaluated for the superficial capillary plexus (SCP) and deep capillary plexus (DCP). Results Twenty eyes of 15 patients with DR were included. FA counted a ...

    7. CHOROIDAL GRANULOMAS VISUALIZED BY SWEPT-SOURCE OPTICAL COHERENCE TOMOGRAPHY ANGIOGRAPHY

      CHOROIDAL GRANULOMAS VISUALIZED BY SWEPT-SOURCE OPTICAL COHERENCE TOMOGRAPHY ANGIOGRAPHY

      Purpose: To assess the visualization of choroidal granulomas with swept-source optical coherence tomography angiography (OCTA). Methods: Consecutive patients with granulomatous choroiditis due to tuberculosis, sarcoidosis, or Vogt–Koyanagi–Harada disease underwent baseline OCTA images using a 12 × 12-mm field of view, and the choroidal slabs were analyzed by two independent examiners who counted the oval areas of flow void. Simultaneously, indocyanine green angiography (ICGA) and enhanced-depth imaging OCT were performed to mark visible choroidal changes corresponding to granulomatous lesions. The lesion areas on OCTA and ICGA were assessed using the in-built caliper tool. Results: Three hundred and one round-shaped areas ...
