AIMS: To review clinical experience, efficacy, and safety of transluminal Nd:YAG laser embolectomy/embolysis (TYE) for retinal artery occlusion. METHODS:  Electronic databases were searched for all published clinical studies and case-reports reporting on TYE in central (CRAO) or branch (BRAO) retinal artery occlusion. Individual patient data was evaluated in a weighted pooled analysis. RESULTS: Sixty-one cases were reported, 47 with BRAO and 14 with CRAO...

PURPOSE: Report a case of concurrent unilateral optic neuritis and central retinal artery occlusion as the presenting signs of syphilis. METHODS: A case report of a 22-year-old man with progressive unilateral vision loss. RESULTS: With no known previous history of syphilis, genital lesions, or other extraocular manifestations, the patient presented with pain with eye movements and decreased color vision. His vision dramatically worsened after a course of oral steroids...

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)...

BACKGROUND: Patients with retinal vascular occlusion disease have an increased risk for ischemic stroke and share some risk factors with cerebrovascular disease. The purpose of this study was to analyze the prevalence of atrial fibrillation (AF) in subjects with retinal vascular occlusive disease and anterior ischemic optic neuropathy and to compare these data to an ischemic stroke group. METHODS: Prospective, observational single-center trial. Subjects with retinal artery occlusion (RAO), retinal vein occlusion (RVO) and anterior ischemic optic neuropathy (AION) were included...

Objective: To evaluate retinal changes in patients who underwent solid organ or bone marrow transplantation. Methods: A retrospective analysis of medical records of patients evaluated from February 2009 to December 2016. All patients included underwent funduscopy. Clinical and demographic data regarding transplantation and ophthalmological changes were collected. Results: A total of 126 patients were analyzed; of these, 108 underwent transplantation and 18 were in the waiting list...

RATIONALE: Visual loss after spine surgery in the prone position is a serious complication. Several cases of central retinal artery occlusion with ophthalmoplegia after spine surgery have been reported in patients with ophthalmic arteries fed by the internal carotid artery (ICA) in a normal manner. PATIENT CONCERNS: A 74-year-old man developed visual loss after undergoing a spinal decompression and fusion operation in the prone position that lasted approximately 5 hours...

OCT has revolutionized the practice of ophthalmology over the past 10-20 years. Advances in OCT technology have allowed for the creation of novel OCT-based methods. OCT-Angiography (OCTA) is one such method that has rapidly gained clinical acceptance since it was approved by the FDA in late 2016. OCTA images are based on the variable backscattering of light from the vascular and neurosensory tissue in the retina. Since the intensity and phase of backscattered light from retinal tissue varies based on the intrinsic movement of the tissue (e...

PURPOSE: To report clinical features of patients with retinal and choroidal diseases presenting with acute visual disturbance during pregnancy. METHODS: In this retrospective case series, patients who developed acute visual loss during pregnancy (including puerperium) and visited a tertiary hospital from July 2007 to June 2015, were recruited by searching electronic medical records. Patients were categorized according to the cause of visual loss. Clinical features and required diagnostic modalities were analyzed in the retinal and choroidal disease group...

Retinal artery occlusion (RAO) should be evaluated as an emergency and can be seen as an ocular analogue to the cerebral apoplex. Both have the same arteriosclerotic risk factors, which are also responsible for cardiac, circulatory and cerebrovascular diseases. That is why an intensive interdisciplinary clarification is necessary to recognize possible comorbidities in time and, if necessary, to treat them. The current therapeutic possibilities of an acute RAO are very limited in their efficiency regarding visual improvement...

The authors describe, for the first time to their knowledge, a case of a congenital macrocystic lymphatic malformation of the orbit with associated venous stasis retinopathy that acutely normalized after drainage and sclerotherapy of the lesion. Prenatal ultrasound revealed prominence of the left orbital soft tissue, and at birth, the patient was noted to have unilateral proptosis, tortuous retinal vessels, and intraretinal hemorrhages in all 4 quadrants in the left eye. MRI demonstrated a primarily intraconal, multiloculated, T2-hyperintense mass consistent with a lymphatic malformation...

AIM: to evaluate the functional state of the retina in patients with antiphospholipid syndrome (APS) through different types of electroretinography (ERG). MATERIAL AND METHODS: The total ERG (t-ERG), local macular ERG (m-ERG), and oscillatory potentials (OP) were recorded in 56 patients with verified APS. RESULTS: In most patients with APS, ERG was of abnormal appearance, particularly, t-ERG was notable for reliably lower a- and b-wave amplitudes (70% of cases), m-ERG - for lower amplitudes and shorter latency (64% of cases)...

PURPOSE: To evaluate whether retrobulbar blood flow and choroidal thickness (CT) are affected in patients with rheumatoid arthritis (RA), and the relationship between these values. METHODS: We evaluated 40 eyes of 20 RA patients and 40 eyes of 20 healthy controls. The enhanced depth imaging optical coherence tomography, color Doppler imaging, was held. Statistical analysis was performed. RESULTS: Peak systolic velocity (PSV) of ophthalmic (OA) and central retinal artery (CRA) were significantly higher in RA...

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: Although peripheral nervous system involvement is common in eosinophilic granulomatosis with polyangiitis (EGPA), central nervous system (CNS) manifestations are poorly described. This study aimed to describe CNS involvement in EGPA. PATIENTS AND METHODS: This retrospective, observational, multicenter study included patients with EGPA and CNS involvement affecting cranial nerves, brain and/or spinal cord. We also undertook a systematic literature review...

We present a case of a 30-year-old woman who suffered a central retinal artery occlusion while taking tranexamic acid. She had no vascular risk factors and was placed on the drug for treatment of menorrhagia. After 1 month of taking the drug, she suffered a central retinal artery occlusion in her left eye. Tranexamic acid was discontinued to prevent vision loss in the following eye. She remains with no perception of light vision in the affected eye.

INTRODUCTION: The present study is the largest registry study ever conducted in Japan exploring the prevalence of familial hypercholesterolaemia (FH) among patients with acute coronary syndrome (ACS). Our study aims to (1) evaluate the status of lipid management and the subsequent risk of major cardiovascular events following hospitalisation of Japanese patients with ACS in real-world clinical practice; (2) determine the proportion of Japanese patients with ACS who achieve the lipid management goal and have a reduction of event risks with strict lipid management (low-density lipoprotein-cholesterol <1...

Imaging techniques based on retinal autofluorescence have found broad applications in ophthalmology because they are extremely sensitive and noninvasive. Conventional fundus autofluorescence measures fluorescence intensity of retinal fluorophores. It mainly derives its signal from lipofuscin at the level of the retinal pigment epithelium. Fundus autofluorescence, however, can not only be characterized by the spatial distribution of the fluorescence intensity or emission spectrum, but also by a characteristic fluorescence lifetime function...
