#1
D Valler, M Ulbig, C P Lohmann, M Maier
Case report of a 23-year-old male patient suffering from Goldmann-Favre syndrome. The patient reported bilateral visual loss since 10 years of age and difficulties with dark adaptation for 2 years. Until recently a final diagnosis was not found. Multimodal imaging using multicolor fundus imaging (MCFI), optical coherence tomography (OCT), fundus autofluorescence (FAF), fluorescein angiography (FLA), electroretinography (ERG) and visual evoked potential (VEP) confirmed the diagnosis. We describe multimodal imaging of this rare hereditary retinal dystrophy...

Purpose: To report a case of bilateral choroidal neovascularization (CNV) in punctate inner choroidopathy (PIC) visualized utilizing optical coherence tomography angiography (OCT-A). Methods: Case report. Results: A 29-year-old woman presented with new visual symptoms in both eyes. Fundoscopic exam revealed bilateral multifocal, small, well-defined lesions consistent with PIC. Optical coherence tomography demonstrated subretinal fluid and retinal pigment epithelium detachments (RPEDs) in both eyes...

Optical coherence tomography (OCT) was one of the biggest advances in ophthalmic imaging. Building on that platform, OCT angiography (OCTA) provides depth resolved images of blood flow in the retina and choroid with levels of detailed far exceeding that obtained with older forms of imaging. This new modality is challenging because of the need for new equipment and processing techniques, current limitations of imaging capability, and rapid advancements in both imaging and in our understanding of the imaging and applicable pathophysiology of the retina and choroid, and the requirement for understanding the origins of image artifacts...

PURPOSE: To determine whether microvasculature dropout (MvD) in the parapapillary choroid is related to the presence of central visual field defects in primary open-angle glaucoma (POAG). DESIGN: Cross-sectional observational study. PARTICIPANTS: Thirty-two POAG patients with an initial parafoveal scotoma (IPFS) within a 10° radius in 1 hemifield and 42 POAG patients with an initial nasal step (INS) within the nasal periphery outside 10° of fixation in 1 hemifield...

Procedural guidance with intravascular ultrasound (IVUS) imaging improves the clinical outcomes of patients undergoing percutaneous coronary intervention (PCI) by: 1) informing the necessity for lesion preparation; 2) directing appropriate stent sizing to maximize the final stent area and minimize geographic miss; 3) selecting the optimal stent length to cover residual disease adjacent to the lesion, thus minimizing geographic miss; 4) guiding optimal stent expansion; 5) identifying acute complications (edge dissection, stent malapposition, tissue protrusion); and 6) clarifying the mechanism of late stent failure (stent thrombosis, neointimal hyperplasia, stent underexpansion or fracture, or neoatherosclerosis)...

In this Letter, we propose an adaptive digital classifier for flow contrast enhancement in optical coherence tomography angiography (OCTA). To solve the depth dependence in the initial motion-based classification, a depth-adaptive motion threshold was determined by performing a histogram analysis of an en-face image at each depth and identifying the static and dynamic voxel populations through fitting. In the follow-up shape-based classification, to adapt to the deformed vessel shapes in OCTA, a modified vesselness function along with an anisotropic Gaussian probe kernel was defined, and then a three-dimensional (3D) Hessian analysis-based shape filtering was utilized for effectively removing the residual static voxels...

BACKGROUND: Although multiple imaging modalities have been tested to predict periprocedural myocardial necrosis (PMN), the superior predictive efficacy of these imaging findings has not been established fully. We sought to evaluate which findings of the coronary imaging tools would best provide predictive efficacy of PMN among optical coherence tomography (OCT), intravascular ultrasound (IVUS), and coronary computed tomography (CCT) angiography. PATIENTS AND METHODS: A total of 130 patients with stable angina pectoris who underwent OCT, IVUS, and CCT examinations for a single de-novo preprocedural lesion were investigated...

BACKGROUND: Optical coherence tomography angiography allows an exact visualization of retinal vascular changes. To interpret the possibilities and limitations using OCTA in clinical practice, we analysed the quality of OCTA findings concerning the evaluability. Furthermore, we correlated our OCTA findings with fluorescein angiography (FAG) in relation of the presence of microaneurysms (MA) and enlargement of the foveal avascular zone (FAZ) in diabetic maculopathy. PATIENTS AND METHODS: 30 eyes from 15 patients with diabetic maculopathy were imaged in 3 × 3mm volume scans and were depicted in OCTA mode (SSADA algorithm)...

BACKGROUND: AZOOR was first described by Gass in 1993 as a syndrome with rapid loss of one or more extensive zones of the outer retinal segments. It is characterized by photopsia, minimal funduscopic changes, and electroretinographic abnormalities. The efficacy of systemic steroids in treating AZOOR has been previously described and advocated by the concept of autoimmune retinopathy. However, the use of intravitreal of sustained-released steroid had not been mentioned to date. CASE PRESENTATION: A 34-year-old man had sudden onset of central scotoma and photopsia in the left eye...

Introduction: Image-based early detection for diabetic retinopathy (DR) needs value addition due to lack of well-defined disease-specific quantitative imaging biomarkers (QIBs) for neuroretinal degeneration and spectropathological information at the systemic level. Retinal neurodegeneration is an early event in the pathogenesis of DR. Therefore, development of an integrated assessment method for detecting neuroretinal degeneration using spectropathology and QIBs is necessary for the early diagnosis of DR...

Purpose: To determine whether combination photodynamic therapy (PDT) and antivascular endothelial growth factor (VEGF) therapy is effective in the management of chronic central serous chorioretinopathy (CSC) recalcitrant to conventional therapy. Methods: This was a retrospective analysis of eight patients with chronic CSC unresponsive to topical nonsteroidal anti-inflammatory drugs, focal photocoagulation, anti-VEGF alone, or PDT alone. All patients were evaluated with a full ophthalmic examination, spectral-domain optical coherence tomography (OCT), fluorescein angiography (FA), and most with indocyanine green angiography (ICGA) followed by treatment with half-fluence PDT and intravitreal anti-VEGF injection (seven bevacizumab, one aflibercept)...

PURPOSE: Clinical trials have demonstrated that retinal blood flow deficiencies are present in patients with open-angle glaucoma (OAG). We introduce a method for facilitating retinal vessel analysis: The intensity of the distal shadow of vessels in optical coherence tomography (OCT) caused by the scattered signal is analyzed, compared between healthy subjects and OAG patients and correlated with OCT angiography (OCT-A) flow density. PATIENTS AND METHODS: We recruited 80 patients with diagnosed OAG (mean age 63...

BACKGROUND: Spontaneous reanalyzed coronary thrombus (SRCT) has been reported in autopsy series, but little is known about SRCT, and it is potentially under-diagnosed in clinical practice.Methods and Results:SRCT identified on OCT were included in a French multicenter series, the Lotus Root French Registry. A total of 34 SRCT were identified on OCT in 33 patients (23 male; median age, 56 years; IQR, 52-65 years); 23/33 patients (70%) presented with angina pectoris and/or dyspnea. Three angiographic aspects were distinguished retrospectively: braided, pseudo-dissected, and hazy...
