BACKGROUND: Central retinal artery occlusion (CRAO) is an ophthalmological emergency, the retinal analog of a stroke. To date there is no consensus or national guidelines on how this disorder should be managed. As academic neurologists and ophthalmologists treat CRAO frequently, we set out to understand how these clinicians approach patients with CRAO with a national survey. METHODS: We identified university-associated teaching hospitals offering vascular neurology, neuro-ophthalmology and/or retina fellowships in the US and asked the directors of the programs to respond to questions in an open response format to profile the acute management of CRAO at their institution...

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 describe the characteristics of retinal telangiectasia in eyes with pathologic myopia. METHODS: The study included 10 patients (18 eyes) who were diagnosed with pathologic myopia combined with retinal telangiectasia. The patients visited our retinal clinic every 3 months. Nine eyes underwent vitrectomy for vision-threatening complications after diagnosis. All eyes underwent comprehensive ophthalmologic examinations including multimodal retinal imaging at presentation and at each follow-up...

REVIEW

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...

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...

The aim of the present study was to investigate the changes of retinal microvascular network in patients with central serous chorioretinopathy (CSCR). A total of fifteen patients (right eye) with CSCR and 15 normal controls (right eye) were recruited. We used optical coherence tomography angiography to scan 6x6 mm macular retinal blood flow images with the application of a series of customized image segmentation processing program software to obtain microvascular and macrovascular density, and compared the superficial microvascular (SMIR), superficial macrovascular ring (SMAR) and the superficial total microvascular (STMI) density between CSCR patients and control group...

Familial exudative vitreoretinopathy (FEVR) is a rare hereditary retinal disorder characterized by the premature arrest of vascularization in the peripheral retina. The aim of the present study was to characterize the clinical presentations of a Chinese family affected by bilateral severe FEVR, and to identify the underlying genetic variations. One family that presented with bilateral FEVR was recruited for this study. Comprehensive ophthalmic examinations, including best‑corrected visual acuity, slit‑lamp examination, fundus photography, fundus fluorescein angiography imaging and electroretinogram were performed...

The aims of this study were to evaluate the effects of CM082 on the development of choroidal neovascularization (CNV) in a laser-induced CNV rat model and to determine the drug concentration in the ocular tissues. After the laser-induced CNV model was established in rats, CM082 was orally administered. The effects of CM082 on the CNV lesions were assessed using fundus fluorescein angiography (FFA), CNV histology, and retinal pigment epithelium- (RPE-) choroid-sclera eyecup analysis. The concentrations of CM082 in the plasma and eye tissues were determined using liquid chromatography-tandem mass spectrometry (LC-MS/MS)...

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...
