REVIEW
Daniel D Esmaili, David S Boyer
Retinal vein occlusions are the second most common form of retinal vascular disease. Previously, laser treatment for branch retinal vein occlusion and intravitreal triamcinolone acetonide for central retinal vein occlusion were the standard of care. Recent studies have demonstrated that anti-vascular endothelial growth factor (anti-VEGF) agents have a superior safety and efficacy profile for the treatment of both branch and central retinal vein occlusions. The use of wide-field fluorescein angiography has also allowed better visualization of the retinal periphery...

PURPOSE: To evaluate the long-term effects of intravitreal dexamethasone implants (IDIs) in eyes with macular edema (ME) due to retinal vein occlusion (RVO). METHODS: We reviewed the records of 10 patients followed for 5 years after they received their first IDI. The main outcome measures included changes in best corrected visual acuity (BCVA), central macular thickness (CMT), and central macular volume (CMV), and the incidence of side effects. RESULTS: Ten patients were included in the study with a mean follow-up of 65...

Retinal vein occlusion (RVO), including central (CRVO), branch (BRVO) and hemicentral and hemispheric RVO, is the second most common vascular cause of visual loss, surpassed only by diabetic retinopathy. The presence and extent of retinal ischemia in RVO is associated with a worse prognosis. On this basis, most previously conducted studies considered iRVO and non-iRVO as separate entities based on set thresholds of existing retinal ischemia, as determined by fundus fluorescein angiography (FFA). Other diagnostic technologies have been used specifically in the differentiation of iCRVO and non-iCRVO...

AIM: To evaluate changes in the ischaemic index (ISI) after targeted retinal photocoagulation (TRP) and to investigate the correlation between these changes and macular oedema (ME). METHOD: Twenty-four eyes of 24 patients with retinal vein occlusion (RVO) with recurrent ME were included. Ultra-widefield fluorescein angiography (UWFFA; Optos 200Tx) was obtained at baseline and every 4 months. The regions of retinal non-perfusion and the total gradable retina were manually segmented on UWFFA images for calculating the global ISI...

PURPOSE: To compare the effects of intravitreal ranibizumab injection and yellow (577 nm) subthreshold micropulse laser treatment in patients with macular edema following non-ischemic branch retinal vein occlusion. METHODS: The medical records of 51 patients who underwent intravitreal ranibizumab (0.5 mg) injection or subthreshold micropulse laser for the treatment of macular edema due to branch retinal vein occlusion were retrospectively reviewed. Subthreshold micropulse laser was administered with a 10% duty cycle, 100 μm spot diameter, 200 ms exposure time...

Purpose: To evaluate the efficacy, safety, and injection frequency of vascular endothelial growth factor (VEGF) antagonists in the treatment of macular edema secondary to retinal vein occlusion (RVO) in clinical practice. Patients and methods: A multicenter retrospective study of the medical records of 165 patients (95 branch RVO, 70 central RVO) treated with at least three anti-VEGF injections in the study eye was conducted. Available data collected for at least 6 months after the first injection included Snellen best-corrected visual acuity (BCVA), central retinal thickness (CRT) by time-domain optical coherence tomography (TD-OCT) or spectral-domain optical coherence tomography (SD-OCT), anti-VEGF injections, other treatments/procedures for RVO, and adverse events...

Background: We previously reported that pinpoint plantar long-wavelength infrared light irradiation (stress-free therapy; SFT) is useful for alleviating insulin resistance and improving intracranial blood flow in patients with type 2 diabetes mellitus. This study was undertaken to evaluate the influences of SFT on chorioretinal hemodynamics (retinal artery and vein blood flows) as well as atherosclerosis-related factors (TG, LDL-C) and VEGF in patients with dyslipidemia. Methods: Four patients with dyslipidemia received 15-minute irradiation with a stress-free apparatus (far-infrared wavelength, 30 mW)...

PURPOSE: To prospectively investigate the injection frequency of aflibercept and ranibizumab in the treatment of macular edema in central retinal vein occlusion. METHODS: Patients with treatment-naive central retinal vein occlusion and macular edema were randomized to receive intravitreal injections with aflibercept (n = 22) or ranibizumab (n = 23) in a treat-and-extend regimen with a follow-up time of 18 months. After 3 loading doses, the treatment intervals were extended by 2 weeks to a maximum of 12 weeks...

Optical coherence tomography angiography (OCTA) is a new, noninvasive technology that enables detailed evaluation of flow in the retinal and choroidal vasculature. The authors believe this to be the first report to describe the optical coherence tomography angiography findings associated with combined central retinal artery occlusion (CRAO) and central retinal vein occlusion (CRVO).

AIM: To evaluate the efficacy and safety of combined anti-vascular endothelial growth factor (VEGF) agents, oral glucocorticoid, and laser photocoagulation therapy for macular edema (ME) secondary to retinal vein occlusion (RVO). METHODS: This study included 16 eyes of 16 patients with RVO-associated ME. Patients were initially treated with oral prednisone and an intravitreal anti-VEGF agent. Two weeks later, patients underwent standard laser photocoagulation. Best-corrected visual acuity (BCVA), central retinal thickness (CRT), and retinal vessel oxygenation were examined over 12mo...

PURPOSE: To evaluate the degree of ischemia in eyes with retinal vein occlusion (RVO) using swept-source optical coherence tomography angiography (SS-OCTA) with the extended field imaging (EFI) technique, which extends the area encompassed by SS-OCTA by scanning through trial frames fitted with a +20-diopter lens. STUDY DESIGN: Retrospective observational study. METHODS: Twenty-three consecutive eyes of 22 patients with RVO underwent 12 × 12 mm SS-OCTA imaging both with and without EFI for determination of extension rate...

Background: Long-term antiepileptic drug (AED) therapy is considered a risk factor of atherosclerosis. Furthermore, the duration of therapy contributes to acceleration of large-vessel atherosclerosis. Therefore, in this study, we tested the hypothesis that long-term AED therapy plays a crucial role in the pathogenesis of microangiopathy in patients with epilepsy. Methods: We recruited 120 patients with epilepsy (age, 18-60 years) and 40 healthy controls. Optical coherence tomography (OCT) was used to measure the central macular thickness and diameters of the retinal artery and vein to evaluate atherosclerotic retinopathy; microalbumin and creatinine levels in urine were assessed to evaluate atherosclerotic nephropathy...

In this report, we describe three cases of retinal macrovessel. Two of the three patients presented to our clinic for annual eye exam and had no visual complaints. The third patient presented because of vision loss in the left eye. Two patients had 20/20 best corrected visual acuity in both eyes and the third patient had 20/20 in the right eye, 20/25 in the left eye. Pupillary exams were normal. Slit-lamp examinations of the anterior segment were unremarkable. Fundus examination revealed macrovessels in the left eyes of two patients and in the right eye of one patient...

REVIEW
Hiroyuki Iijima
Anti-vascular endothelial growth factor agents reduce macular edema and improve vision in eyes with macular edema associated with retinal vein occlusion (RVO), including branch RVO (BRVO) and central RVO. However, not all eyes with resolved macular edema show satisfactory best corrected visual acuity. Photoreceptor impairment can mostly explain the vision loss in these cases. Photoreceptor damage can be caused by subretinal hemorrhage in the central fovea and hard exudates or their precursor derived from concentrated lipoproteins originating from leaky retinal vessel extravasation...

PURPOSE: To evaluate the association between subfoveal choroidal thickness (SFCT) and branch retinal vein occlusion (BRVO) eyes treated with antivascular endothelial growth factor (anti-VEGF) therapy. METHODS: Retrospective cohort study of treatment naïve BRVO eyes treated with 3 monthly anti-VEGF injections. All patients received enhanced depth imaging spectral-domain optical coherence tomography scans to determine SFCT and central macular thickness (CMT). Baseline predictors (particularly SFCT) for functional response (best-corrected visual acuity (BCVA) gain ≥2 lines) were assessed at 3 months using univariate and multivariate analyses...
