PURPOSE: To investigate the morphologic changes on optical coherence tomography angiography (OCTA) of treatment-naive Type 3 neovascularization secondary to exudative age-related macular degeneration after 1 year of anti-vascular endothelial growth factor therapy. METHODS: Consecutive patients diagnosed with treatment-naive early-stage Type 3 neovascularization were enrolled in this retrospective study. All patients underwent color fundus photographs/MultiColor (Heidelberg Engineering) imaging, fluorescein angiography, indocyanine green angiography, structural spectral domain OCT, and OCTA Optovue RTVue XR Avanti (Optovue) at baseline, and repeated OCTA and structural spectral domain OCT at Month 12...

PURPOSE: To report a case that showed centripetal movements of the capillaries in the central macular region after vitrectomy with internal limiting membrane peeling. METHODS: A 57-year-old pseudophakic woman underwent successful vitrectomy with internal limiting membrane peeling and air tamponade for a vitreomacular traction. Optical coherence tomography angiographic images of the 3 mm × 3 mm inner retinal vascular plexus were examined preoperatively and at 3 months postoperatively...

Diabetic macular ischemia (DMI) is a phenotype of diabetic retinopathy (DR) associated with chronic hypoxia of retinal tissue. The goal of this prospective observational study was to report evidence of photoreceptor abnormalities using adaptive optics scanning laser ophthalmoscopy (AOSLO) in eyes with DR in the setting of deep capillary plexus (DCP) non-perfusion. Eleven eyes from 11 patients (6 women, age 31-68), diagnosed with DR without macular edema, underwent optical coherence tomography angiography (OCTA) and AOSLO imaging...

OBJECTIVES: To assess the effect of image registration and averaging on the visualization and quantification of the radial peripapillary capillary (RPC) network on optical coherence tomography angiography (OCTA). METHODS: Twenty-two healthy controls were imaged with a commercial OCTA system (AngioVue, Optovue, Inc.). Ten 10x10° scans of the optic disc were obtained, and the most superficial layer (50-μm slab extending from the inner limiting membrane) was extracted for analysis...

PURPOSE: To evaluate the influence of clinical and multimodal imaging parameters on the duration of acute central serous chorioretinopathy (CSCR) episodes. METHODS: Consecutive patients with first, treatment-naïve central serous chorioretinopathy episodes presenting within 20 days of symptoms onset were prospectively included. They were reevaluated 15 days to 20 days later, followed by monthly evaluation for 6 months. Subfoveal choroidal thickness (SFCT), fluorescein leakage intensity on fluorescein angiography, elevation of retinal pigment epithelium (RPE) lesions at leakage sites, focal/multifocal pattern of indocyanine green angiography (ICGA) at baseline, time-dependent pattern of subretinal fluid (SRF) resorption on OCT using volume segmentation, history of corticosteroid intake and mean blood pressure were evaluated using univariate (Log rank test) and multivariate (Cox proportional hazard regression) survival analysis...

BACKGROUND Central retinal artery occlusion (CRAO) is the occlusion of the central retinal artery resulting in retinal infarction and acute vision loss. Digital subtraction angiography (DSA)-guided superselective ophthalmic artery or selective carotid thrombolysis remains the preferred treatment method for CRAO. This study aimed to evaluate the safety and clinical efficacy of the novel ophthalmic artery branch retrograde thrombolytic intervention for CRAO. MATERIAL AND METHODS Fifty patients with monocular CRAO were enrolled, including 28 males and 22 females (mean age: 55...

A 65-year-old man with presumed choroideremia with preserved central vision was examined by fundus autofluorescence (FAF) and optical coherence tomography angiography (OCTA). FAF showed an isolated area of hyperautofluorescence that involved the fovea. Although the choroid capillary slab of the OCTA showed the medium and large choroidal vessels inferior to the area of retinal pigment epithelium (RPE) atrophy, the choriocapillaris was visible in a relatively wider area than the hyperautofluorescent area in the FAF images...

The aim of this study is to report the coexistence of retinal arterial macroaneurysms (RAMs) and cerebral aneurysms (CAs) in a 58-year-old woman with hypertension. She was noted as having a 1-week history of vision loss in her left eye, along with a 2-month history of a nonspecific headache. Visual acuity was 20/32 in her left eye and 20/20 in her right eye. A fundus examination revealed multiple areas of retinal hemorrhages that were surrounded by circinate exudation in her left eye, as well as the generalized attenuation of the retinal arteries in both of her eyes...

A former 24-week-old premature infant was treated with intravitreal ranibizumab (Lucentis; Genentech, South San Francisco, CA) in one eye and conventional laser in the other eye for aggressive posterior retinopathy of prematurity in both eyes. Fluorescein angiography performed at 149 weeks of age showed persistent avascularity of the temporal peripheral retina in the ranibizumab-treated eye. This case report confirms the need for long-term follow-up of patients treated with ranibizumab monotherapy. [Ophthalmic Surg Lasers Imaging Retina...

Two women with unilateral vision loss from multiple evanescent white dot syndrome were imaged serially with swept-source optical coherence tomography (SS-OCT). En face wide-field structural images revealed peripapillary outer photoreceptor disruption better than conventional fundus autofluorescence imaging. OCT angiography (OCTA) imaging showed preservation of flow within the retinal vasculature and choriocapillaris. As OCTA imaging of the choriocapillaris continues to evolve, these images may lay the groundwork for future investigation...

Optical coherence tomography angiography (OCTA) is a promising technique for non-invasive visualization of vessel networks in the human eye. We debut a system capable of acquiring wide field-of-view (>70°) OCT angiograms without mosaicking. Additionally, we report on enhancing the visualization of peripheral microvasculature using wavefront sensorless adaptive optics (WSAO). We employed a fast WSAO algorithm that enabled wavefront correction in <2  s by iterating the mirror shape at the speed of OCT B-scans rather than volumes...

In this case report we aimed to present a case of Lyme disease presenting as peripheral retinal vasculitis, intermediate uveitis and multifocal white dots in the posterior pole. The patient exhibited vitritis and snowball opacities in both eyes. A diagnosis of Lyme disease was made based on clinical, angiographic and laboratory findings. Fundus fluorescein angiography revealed optic nerve and retinal venous leakage as well as multiple hyperfluorescent foci in both eyes. The patient's symptoms and ocular findings significant improved after treatment with a combination of systemic antibiotics and steroids...

PURPOSE: Trabeculectomy has been regarded as a mainstay of initial treatment in eyes of angle closure glaucoma (ACG) with peripheral anterior synechia > 180° in the Chinese population while its efficacy in secondary ACG with BEST1 gene mutation remains unclear. We set out to investigate the treatment outcome of trabeculectomy for secondary ACG in a group of patients with autosomal recessive bestrophinopathy (ARB). METHODS: In this retrospective case series study, 8 secondary ACG patients with ARB and their 4 recruited family members underwent a thorough ophthalmic examination including best-corrected visual acuity, Goldmann applanation tonometry, gonioscopy, and fundus examinations...

PURPOSE: To describe the outcomes of intravitreal anti-vascular endothelial growth factor (VEGF) in the treatment of retinal angiomatous proliferation (RAP) in real-life practice in 7 Italian centers under the Progetto Luce initiative. METHODS: Clinical data of 95 eyes of 95 patients affected by RAP, regularly followed up and treated with either intravitreal ranibizumab or bevacizumab over 12 months, were examined. After a loading phase of 3 consecutive injections, retreatments were administered following a pro-re-nata regimen on the basis of the persistence or the recurrence of subretinal/intraretinal fluid on optical coherence tomography, or leakage on fluorescein angiography...
