A 15-year-old healthy boy developed acute, rapidly progressing visual loss in left eye following herpes zoster dermatitis, with a combined central retinal artery occlusion (CRAO) and central retinal vein occlusion (CRVO), along with optic perineuritis. Laboratory tests were negative. Despite an empirical, intensive antiviral treatment with systemic corticosteroids, and vision could not be restored in the affected eye. Herpes zoster dermatitis, in an immunocompetent individual, may be associated with a combined CRAO and CRVO along with optic perineuritis, leading to profound visual loss...

BACKGROUND: Leukemic infiltration of the optic nerve is relatively rare. While previously described in acute leukemia, the infiltration in our case represents central nervous system (CNS) metastasis of Burkitt-type lymphoma that developed as a complication of solid-organ transplantation, resulting in a bilateral infiltrative optic neuropathy with sequential, bilateral central retinal artery occlusion (CRAO) and devastating vision loss. METHODS: The medical record, serial ophthalmic examination findings, clinical course, and imaging including magnetic resonance imaging (MRI), fundus photographs, and fluorescein angiography of a single patient were retrospectively reviewed...

INTRODUCTION: The prevalence and etiology of neovascular glaucoma (NVG) as a complication of central retinal artery occlusion (CRAO) is a debated issue. According to some authors, NVG associated with CRAO always involves underlying chronic ocular ischemic syndrome (COIS) as a primum movens for CRAO. However, we describe 5 cases of NVG following CRAO with no underlying COIS, confirmed by carotid Doppler studies and ultrasound color Doppler imaging (USCDI) of the ophthalmic artery (OA)...

PURPOSE OF REVIEW: This review will seek to answer if advances in ophthalmic imaging and evolution of treatment modalities have shed further light on the epidemiology, pathophysiology, diagnosis, and acute management of acute CRAO. RECENT FINDINGS: Imaging characteristics of acute CRAO have been further characterized with the use of fluorescein angiography, optical coherence tomography (OCT), OCT-angiography, and indocyanine-green angiography. Layer segmentation of OCT imaging has found inner retinal layer hyper-reflectivity to be a common finding in acute CRAO...

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...

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)...

Hypoxia plays an important role in several retinal diseases, especially in central retinal artery occlusion (CRAO). Although CRAO has been known for over a hundred years, no cure or sufficient treatment is available. Potential therapies are being evaluated in several in vivo models or primary cultures. However, in vivo models or primary cultures are very time-consuming, expensive, and furthermore several therapies or agents cannot be tested. Therefore, we aimed to develop a standardized organotypic ex vivo retinal hypoxia model...

BACKGROUND: Central retinal artery occlusion (CRAO) is a neurological and ophthalmologic emergency associated with poor visual recovery. There is a dilemma regarding the appropriate treatment, as formal guidelines are lacking. Despite being considered an ocular equivalent of cerebral infarction, the time window of intravenous (IV) thrombolysis administration for maximum efficacy and safety in CRAO remains uncertain. OBJECTIVE: To critically assess the current evidence regarding the safety and effectiveness of IV thrombolysis in the treatment of patients with CRAO...

Central retinal artery occlusion (CRAO) is an ophthalmological emergency. Various treatment modalities have been tried, but none have shown to alter natural history of the disease. Hyperoxia can restore retinal oxygenation, and favourable results were obtained with hyperbaric oxygen therapy (HBOT). We report two patients with sudden visual loss due to CRAO treated with HBOT. Case 1: a 61-year-old female, presented with CRAO in her left eye(OS). She was submitted to eight sessions of HBOT(2.4atmosphere absolute (ATA))...

BACKGROUND: Perfusion of the optic nerve has been widely studied using fluorescein angiography (FAG), which is currently regarded as the criterion standard. However, FAG has adverse effects associated with intravenous contrast administration and is limited in its capacity to characterize and stratify the different vascular layers of the optic nerve and retina. The use of new imaging techniques, such as optical coherence tomographic angiography (Angio-OCT), is therefore important. AIM: A qualitative description is made of the vascular layers of the optic nerve and of how vascular events affect radial peripapillary capillaries (RPC)...

Postoperative visual loss is a rare and devastating complication. The estimated incidence is 0.01-1% after non ocular surgery. It has been reported after spine, cardiac and head and neck surgeries. We report a patient who was operated for cervical laminectomy in prone position and complained of loss of vision in one eye postoperatively. He was thoroughly investigated after visual loss. The case was diagnosed as central retinal artery occlusion (CRAO) of the left eye. Here we consider the potential etiological factors causing this unilateral loss of vision and try to suggest strategies to reduce the incidence of the complication in spinal surgery...

BACKGROUND: Asthma with incomplete reversibility of airway obstruction (IRAO) may often be associated to smoking-induced changes. Nevertheless, a high proportion of patients showing IRAO have never smoked. These patients with IRAO often share features of patients with chronic obstructive pulmonary disease (COPD). Although IRAO is still a poorly defined condition, it has been associated with a higher morbidity and mortality than asthma with complete reversibility of airway obstruction (CRAO) or even COPD alone...

PURPOSE: Ischemic retinal damage can be reversed by hyperbaric oxygen therapy (HBOT) as long as irreversible infarction damage has not developed. However, the time window till irreversible damage develops is still unknown. The study aim was to evaluate the effect of HBOT and determine possible markers for irreversible retinal damage. MATERIALS AND METHODS: Retrospective analysis of 225 patients treated with HBOT for central retinal artery occlusion (CRAO) in 1999-2015...

REVIEW
N Feltgen, A Pielen
Retinal artery occlusion leads to profound visual impairment in the affected eye. It is rarely caused by local ophthalmic pathologies. Most patients present with a large number of cardio- and cerebrovascular risk factors. Visual loss is the leading symptom in central retinal artery occlusion (CRAO), whereas a circumscribed visual field defect is claimed in branch retinal artery occlusion (BRAO). Although many attempts have been made to improve the course of the disease, no effective therapy is available. There is some hope that intravenous fibrinolysis could influence the natural course but the therapeutic window is small (ca...
