This prospective study aimed to investigate metamorphopsia in eyes with central retinal vein occlusion (CRVO) and included 28 eyes (28 patients) with unilateral CRVO that had macular edema (ME) in the acute phase. The ME was treated with anti-vascular endothelial growth factor agents. At baseline and at 1 and 6 months after initiation of treatment, quantitative measurements of metamorphopsia were performed using M-CHARTS and the retinal morphologic changes were examined by optical coherence tomography. At baseline, metamorphopsia was detected on M-CHARTS in 14 (50...

BACKGROUND AND OBJECTIVES: Several imaging modalities have been developed to characterize ischemia inherent in retinal vascular diseases. This study aims to predict the impact and to better establish the mechanisms of visual deterioration. A high-resolution functional imaging device is used, yielding quantitative data for macular blood flow and capillary network features in healthy eyes and in eyes with central retinal vein occlusion (CRVO) or branch retinal vein occlusion (BRVO). PATIENTS AND METHODS: This prospective, cross-sectional, comparative case series measured blood flow velocities (BFVs) and noninvasive capillary perfusion maps (nCPMs) in macular vessels in patients with BRVO/CRVO and in healthy controls using the Retinal Function Imager (RFI; Optical Imaging, Rehovot, Israel)...

Central retinal vein occlusion (CRVO) can cause vision loss. The pathogenesis of CRVO involves a thrombus formation leading to increased retinal capillary pressure, increased vascular permeability, and possibly retinal neovascularization. Vision loss due to CRVO is commonly caused by macular edema. Multiple treatment modalities have been used to treat macular edema. Currently, the most common therapy used is intravitreal inhibition of vascular endothelial growth factor (VEGF). The three most widely used agents are aflibercept, bevacizumab, and ranibizumab and they are effective at blocking VEGF...

BACKGROUND: Central retinal vein occlusion (CRVO), is the second-most common disorder after diabetic retinopathy that threatens the vision related to retinal vessels. One of the main reasons of vision loss is CRVO in acute and chronic forms. OBJECTIVE: The aim of this study was to investigate the response to intravitreal injection of triamcinolone, bevacizumab, and a combined form in patients with CRVO. METHODS: This study was a double-blinded randomized clinical trial conducted on patients with CRVO who were referred to the ophthalmology clinic of Urmia Imam Khomeini Hospital from May 2015 to May 2016...

PURPOSE: To evaluate the effects of dexamethasone intravitreal implant (Ozurdex) and identify risk factors for repeated treatment in patients with macula edema due to branch retinal vein occlusion (BRVO) or central retinal vein occlusion (CRVO). METHODS: Patients followed up for at least 6 months were enrolled from 2013 to 2016. Dexamethasone intravitreal implant was given as the baseline treatment. For evaluation of dexamethasone intravitreal implant effects and complications, the demographics, medical history, best-corrected visual acuity (BCVA), intraocular pressure, and central retinal thickness (CRT) were recorded...

PURPOSE: To report our findings in 2 patients who developed a central retinal vein occlusion (CRVO) and were chronic users of antipsychotic medications. CASE PRESENTATION: Case 1 was a 62-year-old woman who had a sudden reduction of vision in her right eye to 20/2,000. Her fundus showed signs of an impending CRVO with marked macular edema. She had been taking antipsychotic drugs (quetiapine fumarate and risperidone) for about 2 years. She refused anti-VEGF therapy for her macular edema but selected systemic kallidinogenase...

Presentation of a combination of branch retinal artery occlusion (BRAO)/central retinal artery occlusion (CRAO) and central retinal vein occlusion (CRVO) in systemic lupus erythematosus (SLE) is extremely rare. Herein, we have presented the case of a 29-year-old female with SLE, who simultaneously developed bilateral CRVO and BRAO/CRAO in the absence of antiphospholipid syndrome (APS) as a catastrophic form of clinical flare. A combinatorial diagnosis of CRVO and BRAO/CRAO should be considered during clinical flare-up in a patient with SLE who presents with rapidly progressive visual loss...

Purpose: We develop a longitudinal statistical model describing best-corrected visual acuity (BCVA) changes in anti-VEGF therapy in relation to imaging data, and predict the future BCVA outcome for individual patients by combining population-wide trends and initial subject-specific time points. Methods: Automatic segmentation algorithms were used to measure intraretinal (IRF) and subretinal (SRF) fluid volume on monthly spectral-domain optical coherence tomography scans of eyes with central retinal vein occlusion (CRVO) receiving standardized anti-VEGF treatment...

PURPOSE: To evaluate the anatomical and functional outcome of intravitreal dexamethasone implant for macular edema secondary to central (C) or branch (B) retinal vein occlusion (RVO) in patients with persistent macular edema (ME) refractory to intravitreal antivascular endothelial growth factor (VEGF) treatment compared to treatment naïve patients and to dexamethasone-refractory eyes switched to anti-VEGF. METHODS: Retrospective, observational study including 30 eyes previously treated with anti-VEGF (8 CRVO, 22 BRVO, mean age 69 ± 10 yrs), compared to 11 treatment naïve eyes (6 CRVO, 5 BRVO, 73 ± 11 yrs) and compared to dexamethasone nonresponders (2 CRVO, 4 BRVO, 69 ± 12)...

Purpose: Biomarkers for several eye and brain diseases are reviewed, where retinal oximetry may help confirm diagnosis or measure severity of disease. These include diabetic retinopathy, central retinal vein occlusion (CRVO), retinitis pigmentosa, glaucoma, and Alzheimer's disease. Methods: Retinal oximetry is based on spectrophotometric fundus imaging and measures oxygen saturation in retinal arterioles and venules in a noninvasive, quick, safe manner. Retinal oximetry detects changes in oxygen metabolism, including those that result from ischemia or atrophy...

PURPOSE: To examine the effects of retinal endovascular surgery (REVS) with tissue plasminogen activator injection into the retinal vein in central retinal vein occlusion (CRVO) eyes. METHODS: Sixteen consecutive CRVO patients with macular edema and decreased visual acuity who were referred to Toyama University Hospital between March 2014 and February 2016 were included in this study. Changes in visual acuity (VA) and central retinal thickness (CRT) were evaluated up to 6 months after REVS...

AIM: We aimed to evaluate the 1-year efficacy and safety of low-frequency intravitreal bevacizumab in the treatment of macular edema due to retinal vein occlusions (RVOs). METHODS: The study comprised an interventional prospective study of patients with macular edema due to central retinal vein occlusion (CRVO) or branch retinal vein occlusion, followed for 12 months. Treatment-naïve patients with reduced best-corrected visual acuity (BCVA) and central macular thickness (CMT) of at least 250 μm received intravitreal injection of bevacizumab...

BACKGROUND: Ocular vascular occlusions following intraocular procedures are a rare complication. We report a case series of patients with retinal vascular occlusions or anterior ischemic optic neuropathy (AION) after anterior and posterior segment surgery and demonstrate possible risk factors. METHODS: Observational case series. RESULTS: In ten patients, vascular occlusions were observed within ten weeks after intraocular surgery: branch retinal arterial occlusion (BRAO) (n = 2), central retinal artery occlusion (CRAO) (n = 2), central retinal vein occlusion (CRVO) (n = 1), branch retinal vein occlusion (BRVO) (n = 1), anterior ischemic optic neuropathy (AION) (n = 3), and combined central artery and vein occlusion (n = 1)...

IMPORTANCE: In Australia, knowledge of the epidemiology of retinal vein occlusion (RVO) remains scarce due to a paucity of recent population-based data. The National Eye Health Survey (NEHS, 2015-16) provides an up-to-date estimate of the prevalence of RVO in non-Indigenous and Indigenous Australian adults. BACKGROUND: To determine the prevalence and associations of retinal vein occlusion (RVO) in a national sample of Indigenous and non-Indigenous Australian adults...
