OBJECTIVES: This study sought to measure early strut coverage in patients receiving drug-eluting stents (DESs) and to explore the feasibility of short-term dual antiplatelet therapy (DAPT) based on the degree of early strut coverage. BACKGROUND: Data for early strut coverage in patients receiving new-generation DESs, and its implications for DAPT continuation were limited. METHODS: A randomized, multicenter trial was conducted in 894 patients treated with DESs...

PURPOSE: To investigate foveal avascular zone (FAZ) area after surgery in patients with rhegmatogenous retinal detachment (RRD) that involved or uninvolved the macula, and to evaluate the correlation between FAZ area and visual outcomes using swept-source optical coherence tomography angiography (OCTA). MATERIALS AND METHODS: This retrospective case-control study included 34 eyes (34 patients) with recent onset RRD that were successfully repaired with a single, uncomplicated surgical procedure (pars plana vitrectomy with gas tamponade)...

Purpose: We establish and characterize the chronic retinal neovascularization (RNV) induced by intravitreal (IVT) injection of DL-α-aminoadipic acid (AAA) in a rabbit model and investigate the extent and duration of inhibitory actions induced by IVT aflibercept on the RNV. Methods: Rabbits received a single IVT injection of AAA, with weekly follow-up fundus photography, fluorescein angiography (FA), and optical coherence tomography (OCT). After 10 weeks, they received a single IVT aflibercept or control injection...

A 30-year-old woman with photopsias and decreased vision was diagnosed with multiple evanescent white dot syndrome (MEWDS) with an atypical inflammatory subfoveal retinal pigment epithelial detachment (PED) and imaged using swept-source optical coherence tomography (SS-OCT) during several visits. SS-OCT imaging revealed a focal area of attenuated choriocapillaris underneath the PED. An attempt to treat the presumed macular inflammatory lesion with corticosteroids resulted in bilateral exudation consistent with central serous chorioretinopathy...

A patient previously diagnosed with Alport Syndrome was evaluated using multimodal imaging. Optical coherence tomography (OCT) demonstrated significant thinning of the inner retina within the macula, and inner retinal cysts were found in the peripheral macula. OCT angiography demonstrated loss of the choriocapillaris. Abnormal collagen appears to have multiple deleterious effects on the retinal and choroidal structure and vasculature.

BACKGROUND AND OBJECTIVE: To evaluate swept-source optical coherence tomography angiography (SS-OCTA) images in full-thickness macular holes (FTMHs). PATIENTS AND METHODS: SS-OCTA of FTMHs was performed before or after surgery. Vitrectomy with the temporal inverted internal limiting membrane flap technique was used. The authors measured the diameter and area of the foveal avascular zone (FAZ) in superficial and deep retina vasculature. RESULTS: In 88 patients, two artifact types were observed...

Laser-induced choroidal neovascularization (CNV) is a well-established model to mimic the wet form of age-related macular degeneration (AMD). In this protocol, we aim to guide the reader not simply through the technical considerations of generating laser-induced lesions to trigger neovascular processes, but rather focus on the powerful information that can be obtained from multimodal longitudinal in vivo imaging throughout the follow-up period. The laser-induced mouse CNV model was generated by a diode laser administration...

BACKGROUND AND OBJECTIVE: To demonstrate the coexistence of polypoidal choroidal vasculopathy (PCV) with type 2 neovascularisation (NV), we used multimodal imaging, including spectral-domain optical coherence tomography angiography (SD-OCTA), to identify both types of lesions in the same eye. STUDY DESIGN: This retrospective case series reviewed patients with PCV diagnosed with indocyanine green angiography (ICGA), fluorescein angiography (FA), SD-OCT and SD-OCTA...

Purpose: Here, we have tried to quantify the chorioretinal blood perfusion in patients who are clinically identified to be suffering from retinal ischemia using arterial spin labelling (ASL) MRI. Method: Four participants, diagnosed with retinal ischemia based on their structural OCT and angiography test, were then scanned using anatomical MRI as well as ASL. We optimized MR parameters to maximize resolution and target fixation, blinking, and breathing ques to minimize motion artifacts...

PURPOSE: To compare the foveal avascular zone (FAZ) area measurements produced by different optical coherence tomography angiography (OCTA). METHODS: Healthy enrolled volunteers underwent OCTA using 2 different devices: Spectralis HRA+OCTA (Heidelberg Engineering, Heidelberg, Germany) and RS-3000 Advance (Nidek, Gamagori, Japan). Two graders measured FAZ in both superficial (SCP) and deep (DCP) retinal capillary plexuses. The SCP and DCP en face images were visualized automatically segmenting 2 separate slabs defined by the arbitrary segmentation lines created by the software of each OCT device...

To evaluate ocular fundus biological changes after scleral collagen cross-linking (CXL) with riboflavin/ ultraviolet A (UVA) on rhesus monkeys in vivo by analyzing retina and choroid biological parameters. Six 3-year-old male rhesus monkeys (12 eyes) were observed in this study, with scleral CXL procedures applied on superior temporal equatorial sclera on random eyes of all rhesus. Optical coherence tomography (OCT) and optical coherence tomography angiography (OCTA) examination were performed before and 1 week, 1 month, 3 months and 6 months after CXL...

PURPOSE: To report a case of choroidal neovascularization (CNV) associated with rubella retinopathy (RR) treated with intravitreal aflibercept. CASE PRESENTATION: A 15-year-old girl presented a complaint of visual decrease in her left eye. She had a history of hearing decrease since she was 1 year old in addition to patent ductus arteriosus. On ocular examination, the best corrected visual acuity (BCVA) was 20/20 in the right eye and 20/400 in the left eye. Dilated fundus examinations revealed a classic salt-and-pepper appearance in both eyes and a whitish subretinal lesion with retinal hemorrhages in the left macula...

Intraocular pressure (IOP) is an important risk factor for glaucoma, and the response of the ONH and surrounding tissues to elevated IOP are often investigated to better understand pathophysiology. In vivo structure including that of the optic nerve head (ONH) and surrounding tissue of the eye are often assessed using optical coherence tomography (OCT). With advances in OCT technology, both large vessels and capillaries can be imaged non-invasively (OCT Angiography). Because a significant portion of retinal thickness is comprised of vasculature, the purpose of the current study was to investigate OCT structural and vascular changes in healthy non-human primate eyes with systematic graded increases and decreases in IOP...

BACKGROUND: The purpose of this study is to examine the choridal perfusion in patients with chronic central serous chorioretinopathy (CSC) after half-fluence photodynamic therapy (PDT) in the early post-treatment period. METHODS: This retrospective study included patients with chronic CSC. Indocyanine green angiography (ICGA) guided half-fluence PDT was applied to the all eyes. Best corrected visual acuity (BCVA) was assessed by Snellen chart and central retinal thickness (CRT) and subfoveal choroidal thickness (SFCT) was measured by spectral domain optical coherence tomography (SD-OCT) before PDT and at 3 and 30 days following the therapy...

BACKGROUND AND AIMS: This study examined the impact of CD14++CD16+ monocytes on coronary plaque vulnerability, as assessed by optical coherence tomography (OCT), and investigated their association with daily glucose fluctuation. Although increased CD14++CD16+ monocyte levels have been reported to increase cardiovascular events, their impact on coronary plaque vulnerability in coronary artery disease (CAD) patients with or without diabetes mellitus (DM) remains unclear. METHODS: This prospective observational study included 50 consecutive patients with CAD, receiving lipid-lowering therapy and undergoing coronary angiography and OCT...
