Multimodal Imaging of Microvascular Abnormalities in Retinal Vein Occlusion.

The technologies of ocular imaging modalities such as optical coherence tomography (OCT) and OCT angiography (OCTA) have progressed remarkably. Of these in vivo imaging modalities, recently advanced OCT technology provides high-resolution images, e.g.

Morphologic Classifications and Locations of Microaneurysms and Clinical Relevance in Branch Retinal Vein Occlusion.

Purpose: To classify microaneurysms (MAs) and investigate the relationships with retinal edema in eyes with branch retinal vein occlusion (BRVO).

Study Design: Retrospective, observational, consecutive case series.

Methods: Eyes with MAs due to BRVO that underwent optical coherence tomography angiography (OCTA) were enrolled.

Multimodal Imaging in a Case of Idiopathic Neuroretinitis.

A 37-year-old woman presented with painful visual loss in the left eye for 2 weeks. The best-corrected visual acuity was 20/200. Ophthalmic examination of the left eye revealed vitreous cells, optic disc swelling, serous retinal detachment, and macular star-figure hard exudates.

Collateral vessels on optical coherence tomography angiography in eyes with branch retinal vein occlusion.

Aims: To detect collateral vessels using optical coherence tomography angiography (OCTA) in eyes with branch retinal vein occlusion (BRVO) and to investigate the associations with visual outcomes and macular oedema.

Methods: Eyes with macular oedema secondary to BRVO that underwent OCTA at baseline and were followed up for more than 6 months were enrolled. The presence of collaterals, whether the collaterals were leaky or not, and the associations with visual outcomes and macular oedema were investigated.

Structural and Functional Analyses of Retinal Ischemia in Eyes with Retinal Vein Occlusion: Relationship with Macular Edema or Microaneurysm Formation.

Purpose: To study the structural and functional changes of retinal ischemia and investigate their association with macular edema (ME) or microaneurysm (MA) formation in eyes with retinal vein occlusion (RVO).

Methods: Sixty eyes of 30 patients (27 eyes with branch [b]RVO, 3 with central RVO, and 30 fellow eyes) were retrospectively reviewed. Optical coherence tomography (OCT), OCT angiography (OCTA), and microperimetry were performed simultaneously to measure retinal thickness and sensitivity.

Peripheral Microvascular Abnormalities Detected by Wide-Field Fluorescein Angiography in Eyes with Branch Retinal Vein Occlusion.

Purpose: To evaluate the location of microvascular abnormalities using wide-field fluorescein angiography (WFFA) and investigate the impact on visual outcome in eyes with branch retinal vein occlusion (BRVO).

Methods: Forty eyes of 39 patients (24 males and 15 females with an average age of 71 years) were retrospectively reviewed. One patient had BRVO bilaterally.

Preoperative optical coherence tomography visualization of epiretinal membranes enhances surgical strategies.

Purpose: The aim of this study was to evaluate the usefulness of preoperative optical coherence tomography (OCT) findings in patients with macular epiretinal membrane (ERM) for the planning of surgical strategy.

Patients And Methods: One hundred twenty-three eyes of 121 patients (49 men, 72 women; mean age, 66 years) with an idiopathic ERM were enrolled. All patients underwent an ophthalmic examination including indirect ophthalmoscopy and OCT (Cirrus HD-OCT 4000 and/or 5000).

Retinal Hemodynamics Seen on Optical Coherence Tomography Angiography Before and After Treatment of Retinal Vein Occlusion.

Purpose: This study evaluates the retinal hemodynamics using optical coherence tomography angiography (OCTA) before and after anti-vascular endothelial growth factor (VEGF) therapy in patients with macular edema associated with retinal vein occlusion (RVO).

Methods: Twelve patients (23 eyes; mean age, 64 years) were included (eight eyes with branch RVO, four with central RVO, and 11 unaffected fellow eyes. The best-corrected visual acuity (BCVA) and central retinal thickness (CRT) were measured before and 6 months after treatment.

Characteristics of Polypoidal Choroidal Vasculopathy Evaluated by Optical Coherence Tomography Angiography.

Purpose: The purpose of this study was to compare the angiographic findings of polypoidal choroidal vasculopathy (PCV) detected by indocyanine green angiography (ICGA) and en face optical coherence tomography angiography (OCTA).

Methods: The study design was a retrospective chart review of 20 eyes with a clinical diagnosis of treatment-naive PCV, seen at Nagoya City University Hospital between December 2014 and January 2016. Indocyanine green angiography was performed with Heidelberg Retina Angiography 2 and OCTA was performed by using Avanti RTVue XR.

Microaneurysms cause refractory macular edema in branch retinal vein occlusion.

Intravitreal anti-vascular endothelial growth factor (VEGF) agents can treat macular edema (ME) in branch retinal vein occlusion (BRVO). However, refractory ME, the mechanism of which is not well elucidated, occurs frequently. Sixty-six eyes with ME secondary to BRVO were enrolled in this retrospective observational case-control study.

[Evaluation of Diabetic Retinopathy with Ultra-wide Field Fluorescein Angiography].

Purpose: The ultra-wide field scanning laser ophthalmoscope (Optos 200Tx, Optos, Scotland, UK) provides retinal images of 200 degrees in a single capture which covers more than 80% of the retina. Fluorescein angiography with Optos 200Tx is useful to visualize the microcirculations of peripheral retina. It allows to evaluate peripheral pathology more precisely than conventional fundus photography.

Microvascular Abnormalities on Optical Coherence Tomography Angiography in Macular Edema Associated With Branch Retinal Vein Occlusion.

Purpose: To determine the ability of optical coherence tomography (OCT) angiography to image the microvascular structures compared with fluorescein angiography (FA) in patients with macular edema associated with branch retinal vein occlusion (BRVO).

Design: Retrospective, observational, consecutive case series.

Methods: Twenty-eight eyes of 27 patients (14 men, 13 women; mean age, 68.
