PURPOSE: The aim of this report was to describe multimodal ocular imaging findings in a patient who presented with a ruptured retinal arterial macroaneurysm (RAM) associated with toxoplasmic Kyrieleis arteriolitis. METHODS: We report the case of a 64-year-old man with a history of systemic hypertension and dense amblyopia of the left eye who presented with decreased vision and new floaters in the left eye. Color fundus photography, spectral-domain optical coherence tomography, fluorescein angiography, and indocyanine green angiography were used as diagnostic imaging tools...

BACKGROUND: The aim was to make a real-world comparison of the efficacy of ranibizumab, dexamethasone and grid laser treatments in macular oedema due to branch retinal vein occlusion (BRVO). METHODS: Forty-four eyes of 44 consecutive patients with macular oedema secondary to BRVO were included. Treatment arms comprised standard care (StCARE, n = 15), intravitreal ranibizumab (RNB, n = 14) and dexamethasone implant (DEX, n = 15). No rescue laser was performed in DEX and RNB groups...

PURPOSE: The present study aimed to investigate the morphology of the retinal vasculature in eyes with branch retinal vein occlusion (BRVO) using optical coherence tomography (OCT) angiography. DESIGN: Observational case series. METHODS: Fluorescein angiography (FA) and OCT angiography were used to examine macular area and the retinal vasculature at the affected arteriovenous (AV) crossing in 46 patients with BRVO. RESULTS: FA revealed that the affected AV crossing pattern involved arterial overcrossing in 23 eyes (50...

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...

In this observational and cross-sectional study, capillary non perfusion (CNP) and vascular changes in branch retinal vein occlusion (BRVO, sample size (n) = 26) and choroidal neovascularization (CNV, n = 29) were evaluated. Subjects underwent imaging using Optical coherence tomography angiography (Angiovue™ OCTA , RTVue XR, Optovue Inc., Fremont, CA). Local fractal analysis was applied to the OCTA images of superficial, deep and choriocapillaries layer. CNP area (BRVO eyes) and vascular parameters were computed using local fractal based method...

PURPOSE: To compare the efficacy of intravitreal injection of ranibizumab, dexamethasone implant and aflibercept for the management of macular edema (ME) related to branch retinal vein occlusion (BRVO). METHODS: This retrospective and comparative study included 62 eyes of 62 patients with BRVO and ME. Patients received one of the following treatments: 0.5 mg ranibizumab (group 1, n = 22), 0.7 mg dexamethasone implant (group 2, n = 20) and 2 mg aflibercept (group 3, n = 20)...

WHAT IS KNOWN AND OBJECTIVE: Therapeutic effects of anti-VEGF agents, corticosteroids and laser therapy have been previously examined for treating macular oedema secondary to branch and central retinal vein occlusion (BRVO and CRVO). However, anti-VEGF efficacy has not been previously compared to corticosteroid or laser therapy efficacy. We performed a meta-analysis to compare these treatments. METHODS: Pertinent publications were identified through comprehensive literature searches...

PURPOSE: To evaluate the effects of intravitreal ranibizumab injection (IVR) on metamorphopsia in patients with branch retinal vein occlusion (BRVO) and to assess the relationship between retinal microstructure and metamorphopsia. METHODS: Subjects were 39 eyes of 39 patients with branch retinal vein occlusion. The severity of metamorphopsia was quantified using the M-CHARTS before and 1, 2, 3, 4, 5, and 6 months after treatment. Based on optical coherence tomography (OCT) images, we assessed central retinal thickness (CRT) and status of the external limiting membrane (ELM) and ellipsoid zone (EZ)...

BACKGROUND: The correlation between the short- and long-term effects of intravitreal ranibizumab (IVR) on macular edema after branch retinal vein occlusion (BRVO) remains unclear. We assessed the correlation between the short- and long-term effects of IVR on macular edema after BRVO. METHODS: Twenty-one eyes with macular edema after BRVO were enrolled in this prospective observational study. We measured the foveal thickness (FT) and the best-corrected visual acuity (BCVA) before, 1 day after, and 1 month after IVR (0...

PURPOSE: To analyze the repeatability of thickness measurements of the central macula, ganglion cell-inner plexiform layer (GC-IPL), and retinal nerve fiber layer (RNFL) using spectral-domain optical coherence tomography (SD-OCT) before and after treatment of macular edema in branch retinal vein occlusion (BRVO). METHODS: We analyzed patients with BRVO who visited our retinal clinic. The repeatability of the thickness measurements were compared using the intraclass correlation coefficient (ICC) and coefficient of variation (COV) of affected versus normal fellow eyes...

Vitreomacular adhesion (VMA) represents a prognostic biomarker in the management of exudative macular disease using anti-vascular endothelial growth factor (VEGF) agents. However, manual evaluation of VMA in 3D optical coherence tomography (OCT) is laborious and data on its impact on therapy of retinal vein occlusion (RVO) are limited. The aim of this study was to (1) develop a fully automated segmentation algorithm for the posterior vitreous boundary and (2) to study the effect of VMA on anti-VEGF therapy for RVO...
