Purpose: To compare the capability of indocyanine green angiography (ICGA) and optical coherence tomography angiography (OCTA) in detecting choroidal neovascularization (CNV). Methods: In this prospective study, patients with CNV detected with fluorescein angiography (FA) underwent ICGA and OCTA, spectral domain OCT (SD-OCT), and infrared or fundus color photographs. CNV lesions were outlined on ICGA and OCTA images, and the composition and size of the CNV was documented...

In this review, we summarize the progression of several parameters assessed by spectral-domain optical coherence tomography (SD-OCT) in recent years for the detection of glaucoma. Monitoring the progression of defects in the retinal nerve fiber layer (RNFL) thickness is essential. Imaging and analysis of retinal ganglion cells (RGCs) and inner plexiform layer (IPL), respectively, have been of great importance. Optic nerve head (ONH) topography obtained from 3D SD-OCT images is another crucial step. Other important assessments involve locating the Bruch's membrane opening (BMO), estimating the optic disc size and rim area, and measuring the lamina cribrosa displacement...

Our objective was to compare the diagnostic accuracies of and to determine the correlations between the disc damage likelihood scale (DDLS) and anatomical and functional tests used for glaucoma detection. A total of 54 healthy subjects (54 eyes) and 47 primary open-angle glaucoma patients (47 eyes) were included in this cross-sectional observational study. DDLS scores and cup-to-disc (C/D) ratios were evaluated. Subjects underwent standard automated perimetry (SAP), optic disc and retinal nerve fiber layer (RNFL) imaging with time and spectral-domain optical coherence tomography (TD and SD-OCT), Heidelberg Retina Tomograph (HRT II), and scanning laser polarimetry (GDx-VCC)...

BACKGROUND: Coxsackieviruses are members of a group of viruses called the enteroviruses, which may cause respiratory and gastrointestinal symptoms, erythema, meningoencephalitis, myocarditis, pericarditis, and myositis. Unilateral acute idiopathic maculopathy caused by coxsackievirus A16 has been associated with hand, foot, and mouth disease, but only a few reports describe retinitis associated with coxsackievirus serotype B3 or B4. We report a case of bilateral multifocal obstructive retinal vasculitis that developed after coxsackievirus A4 infection...

PURPOSE: The purpose of this study was to investigate the occurrence of outer retinal tubulation (ORT) among patients with different types of choroidal neovascularization (CNV) over time. MATERIALS AND METHODS: In this retrospective chart review, disease type was classified as typical age-related macular degeneration (t-AMD), polypoidal choroidal vasculopathy (PCV), retinal angiomatous proliferation (RAP), or myopic CNV (mCNV). Spectral domain-optical coherence tomography (SD-OCT) images were evaluated for the appearance of ORT and subretinal fibrosis and fluid...

PURPOSE: To evaluate the early effects of dexamethasone (DEX) intravitreal implants in patients with diabetic macular edema (DME). METHODS: This was a prospective, single-arm, interventional clinical series. Eighteen patients (18 eyes) with chronic/recalcitrant or naive DME were included. Patients underwent single DEX intravitreal implant. Clinical assessments, including ophthalmologic examination, central retinal thickness (CRT) measurement by spectral-domain optical coherence tomography (SD-OCT) scan, best-corrected visual acuity (BCVA), and intraocular pressure (IOP) were carried out at baseline, 1-3 hours, and then 3, 7, and 30 days after treatment...

INTRODUCTION: The newly developed optical coherence tomography angiography (OCT-A) has provided new means to depict the vascular plexus in neovascular age-related macular degeneration (nAMD). If these images are to be used as a basis for therapeutic decisions, it is of vital importance to classify choroidal neovascularization (CNV) as either classical or occult. This study aimed at comparing the findings in OCT-A imaging of CNV with the traditional multimodal imaging through fluorescein angiography (FLA) and indocyanine green angiography (ICGA)...

This cross-sectional study compared the retinal morphology between patients with progressive supranuclear palsy (PSP) and healthy controls. (The retinal nerve fiber layer (RNFL) around the optic disc and the retina in the macular area of 22 PSP patients and 151 controls were investigated by spectral domain optical coherence tomography (SD-OCT). Additionally, the RNFL and the nerve fiber index (NFI) were measured by scanning laser polarimetry (SLP). Results of RNFL measurements with SD-OCT and SLP were compared to assess diagnostic discriminatory power...

BACKGROUND: To report the clinical, electrophysiological and the anatomical findings in a patient with Kearns-Sayre syndrome (KSS). CASE PRESENTATION: We present the case of a 55-year-old female with KSS, who developed systemic features and ocular manifestations as ophthalmoplegia and retinal dysfunction, that were corroborated by electrophysiological test and High Definition Spectral Domain Optical Coherence Tomography (HD SD OCT) and OCT-Angiography (OCT-A). CONCLUSION: We report a patient with KSS, accompanied by some alterations of the RPE and photoreceptors observed in the external HD SD OCT and OCT-A...

Incurable neuroretinal degeneration diseases cause severe vision loss and blindness in millions of patients worldwide. In previous studies, we demonstrated that transplanting human bone marrow stromal cells (hBMSCs) in the extravascular spaces of the choroid (EVSC) of the Royal College of Surgeon rats ameliorated retinal degeneration for up to 5 months. Assessing the safety of hBMSC treatment and graft survival in a large animal is a crucial step before initiating clinical trials. Here, we transplanted hBMSCs into the EVSC compartment of New Zealand White rabbits...

A 54-year-old white man presented with a "blind spot" temporally in his left eye. Best-corrected visual acuity in the affected eye was 20/20 and Humphrey visual field revealed an enlarged blind spot. Funduscopic examination revealed subtle peripapillary pigmentary changes corresponding to a well-demarcated peripapillary region of hyper- and hypoautofluorescence on fundus autofluorescence (FAF). Outer retinal degenerative changes were detected on spectral domain optical coherence tomography (SD-OCT). A diagnosis of Acute zonal occult outer retinopathy (AZOOR) was made based on clinical history and imaging studies...
