Celiac disease (CD) is a digestive disorder caused by an abnormal immune reaction to gluten, leading to severe malabsorption syndrome. Central retinal vein occlusion (CRVO) was reported in a couple of cases worldwide in patients with this disease entity. Herein, we are reporting a rare case of combined central retinal vein and artery occlusion in a young female celiac disease patient presented with a counting finger vision at six feet and improved to 20/60 vision after conservative management.

Although ocular complications following COVID-19 vaccination have been reported, particularly retinal vascular occlusion and uveitis, their definitive causal relationships remain uncertain. This report presents a case of central retinal artery occlusion (CRAO) with paracentral acute middle maculopathy (PAMM) developed one day after receiving Pfizer COVID-19 vaccine, with a favorable outcome. The patient experienced sudden vision loss in her left eye, and her vision dropped to hand motion the day after vaccination...

OBJECTIVES: Central retinal artery occlusion (CRAO) is a stroke of the retina potentially amenable to intravenous thrombolysis (IVT). We aimed to determine feasibility of an emergency treatment protocol and risk profile of IVT for CRAO in a comprehensive stroke center (CSC). METHODS: We performed a retrospective, observational cohort study including patients with acute CRAO admitted to a CSC over 4 years. Patients are offered IVT if they present with acute vision loss of ≤ 20/200 in the affected eye, have no other cause of vision loss (incorporating a dilated ophthalmologic exam), and meet criteria akin to acute ischemic stroke...

Purpose: To determine the time-based incidence of total blindness after central retinal artery occlusion (CRAO) with secondary ocular neovascularization (ONV). Methods: In this retrospective cohort study, electronic records were queried using ICD-9 and ICD-10 codes to identify patients with secondary ONV post-CRAO. Patients with possible alternative ONV etiologies, previous panretinal photocoagulation (PRP), and/or previous antivascular endothelial growth factor (anti-VEGF) therapy were excluded. Clinical data included demographics, medical comorbidities, ONV manifestations, medical/surgical management, and best-corrected visual acuity (BCVA)...

INTRODUCTION AND IMPORTANCE: Acute sinusitis can cause intraorbital complications. Although subperiosteal abscesses generally do not cause severe vision loss, rare cases of decreased vision due to central artery or vein occlusion have been reported since 2003. Central retinal artery occlusion (CRAO) is an eye emergency that can cause sudden loss of vision. This condition is commonly found in elderly individuals with other metabolic diseases. The authors report a case of a type 2 diabetes mellitus (T2DM) patient with CRAO due to suspected rhino-orbital-cerebral mucormycosis (ROCM)...

INTRODUCTION: Reperfusion therapies represent promising treatments for patients with Central Retinal Artery Occlusion (CRAO), but access is limited due to low incidence and lack of protocols. We aimed to describe the benefit of implementing a Retinal Stroke-Code protocol regarding access to reperfusion, visual acuity and aetiological assessment. PATIENTS AND METHODS: Prospective cohort study performed at a Comprehensive Stroke Centre. Criteria for activation were sudden monocular, painless vision loss within 6 h from onset...

CLINICAL RELEVANCE: Central retinal artery occlusion (CRAO) is an ophthalmic emergency with a poor prognosis. Several initial CRAO presentation factors can influence the final visual outcome. Fluorescein angiography filling of retinal vessels in CRAO has not been studied in great detail. BACKGROUND: The aim of this paper is to study the aberrant filling of the retinal vessels on fluorescein angiography in patients with CRAO and understand its clinical relevance...

PURPOSE: To assess visual acuity (VA) outcomes in a large cohort of patients diagnosed with nonarteritic central retinal artery occlusion (CRAO), and to ascertain whether time from symptom onset to presentation, presenting VA, or conservative treatment delivery (anterior chamber paracentesis, ocular massage, intraocular pressure lowering drugs, hyperventilation, or some combination of those) impacted ultimate VA outcomes. DESIGN: Retrospective cohort study. SUBJECTS: The study included 794 patients who presented with CRAO between 2011 and 2020...

Local intra-arterial fibrinolysis (LIF) is a promising therapeutic option for CRAO. However, the narrow time window of 6 h has greatly limited the application of LIF. In this study, we explored the efficacy of LIF beyond the conventional time windows and compared the result with conservative therapy. This prospective study included 179 CRAO patients with baseline visual acuity (VA) ≤ 20/400 treated at Renmin Hospital of Wuhan University. The mean time from vision loss to presentation was 5...

PURPOSE: To describe a typical case of acute central retinal artery occlusion (CRAO) with an ink-blot pattern of hyperfluorescent leak on fundus fluorescein angiography (FFA). CASE DESCRIPTION: A 21-year-old woman came to the clinic with one day of painless right eye vision loss. Her right eye had finger counting at ½ meter. Her right eye had a relative afferent pupillary defect, but her anterior segment and intraocular pressure of both eyes were normal. RESULTS: The right eye fundus showed signs of acute CRAO with severe grade on optical coherence tomography (OCT)...

We report a rare case of central retinal artery occlusion (CRAO) with triple cilioretinal artery sparing in a 76-year-old male with hypertension who presented with sudden diminution of vision in the left eye (OS) for one day. Optical coherence tomography angiography (OCTA) demonstrated the presence of three cilioretinal arteries and the absence of flow signals in the rest of the macula. Primary ophthalmic treatment was instituted immediately in the form of ocular massage, and acetazolamide 500 mg per oral (PO) stat was given...

The authors report a rare case of pediatric central retinal artery occlusion (CRAO) and spontaneous late recovery, with associated literature review. A retrospective review of patient medical records and literature search of four relevant databases was conducted. A 7-year-old girl with sudden, painless loss of vision in her right eye was referred to the authors' center where she was found to have a CRAO with hand motion visual acuity. One month later, the patient developed multiple retinal hemorrhages throughout the fundus...

INTRODUCTION: Restricted retinal diffusion (RDR) has recently been recognized as a frequent finding on standard diffusion-weighted imaging (DWI) in central retinal artery occlusion (CRAO). However, data on early DWI signal evolution are missing. PATIENTS AND METHODS: Consecutive CRAO patients with DWI performed within 24 h after onset of visual impairment were included in a bicentric, retrospective cross-sectional study. Two blinded neuroradiologists assessed randomized DWI scans for the presence of retinal ischemia...

Central retinal artery occlusion (CRAO) is an ophthalmologic emergency that can lead to irreversible loss of vision. Intravenous thrombolysis (IVT) has been used experimentally for its treatment. Our study aimed to evaluate the effect of emergency IVT on CRAO and its impact on visual acuity outcomes. We conducted a retrospective observational study of patients with CRAO. A total of 46 patients with CRAO were analysed; 16 patients received IVT treatment (IVT group) while 30 did not (no-IVT group). Seven patients from the IVT group received IVT early, within 4...

BACKGROUND: To analyze the clinical profile, presentation, possible pathophysiology, and outcomes of central retinal artery occlusion (CRAO) following blunt trauma in pediatric subjects. METHODOLOGY: The medical charts of subjects aged 18 years or less with a diagnosis of CRAO following blunt ocular trauma were analyzed retrospectively for demography, details of the trauma, ocular findings, additional imaging reports if any, and final outcome. A Medline search was done (key words like central retinal artery occlusion, blunt trauma, children, pediatric subjects, and adolescents) to gather information available in the literature on the subject...

OBJECTIVES: Central and branch retinal artery occlusions are disabling ischemic strokes of the retina for which established acute treatments are lacking. This is the first published report of the use of intravenous tenecteplase (TNK) for retinal artery occlusion, in which we describe the clinical course of four patients with central retinal artery occlusion (CRAO) and one patient with branch retinal artery occlusion (BRAO). MATERIALS AND METHODS: Patients were retrospectively recruited to the study from two stroke centers...

UNLABELLED: Central retinal artery occlusion (CRAO) is a rare emergency department presentation with high morbidity and potential for long-term vision loss. Additionally, this finding requires an expeditious embolic workup for possible systemic pathology (i.e., stroke). The gold standard for diagnosis is visualization of a pale retina with a "cherry-red spot" on the fovea seen under dilated fundoscopic examination. However, performing a dilated fundoscopic exam is often not practical and technically challenging in the emergency room setting...

PURPOSE: To identify all reported cases of retinal artery occlusion (RAO) associated with patent foramen ovale (PFO) in the literature and present a similar case of CRAO from our clinic. METHODS: PubMed database was searched for studies reporting RAO in individuals with PFO. Relevant data were tabulated and reviewed. We estimated each case's Risk of Paradoxical Embolism (RoPE) score. RESULTS: 23 cases of CRAO (n=10; including ours), BRAO (n=10), and CILRAO (n=3) were reviewed...

To characterize and compare macular vessel density in central retinal artery occlusion (CRAO) eyes with retinal arterial cannulation and CRAO eyes with standard treatment. This study was Cross-sectional, observational study. Twenty-two eyes with nonarteric CRAO which underwent retinal arterial cannulation and 19 eyes with nonarteric CRAO with standard treatment were included. Optical coherent tomography angiography (OCTA)-based macular vessel density and visual acuity were examined. The dynamic ranged-based normalized rates of vessel density was compared within each group at the first visit to the clinic and 7 days after the onset...

OBJECTIVE: To describe a single surgeon's experience utilizing prompt primary slow-burn transscleral cyclophotocoagulation (CPC) with prior or concurrent anti-VEGF and subsequent aqueous shunt as needed in NVG eyes with near-total synechial angle closure at presentation. METHODS: Retrospective chart review of all NVG patients with uncontrolled IOP, active anterior segment NV, near-total synechial angle closure, and no contraindications to prompt anti-VEGF who received CPC within 3 days of presentation with at least 6 months of follow-up...
