Correspondence to: Yi Yang. Department of Ophthalmology, Guangdong General Hospital, #106, Zhongshan Second Road, Guangzhou 510080, China. Email: [email protected]. Background: To explore the difference between the outcomes of correlations between a series of variables and adverse reactions (ARs) to fluorescein from univariate and multivariate analysis and to evaluate the nausea effects in different age groups. Methods: A retrospective study of patients undergoing consecutive fluorescein angiography between March 2010 and February 2012 was conducted. No patients were excluded on the ground of age, presence of atopy, allergy history, previous procedures without severe allergic ARs, asymptomatic hypertension and kidney failure with serum creatinine levels lower than 250 μmol/L or with renal dialysis. Results: A total of 829 patients were enrolled and 22.2% of them had ARs. The majority of reactions were nausea (12.1%) which occurred less when age became old (P<0.0001). When the correlations between a series of variables and ARs were assessed separately, age (P<0.0001), prior reactions (P<0.0001) and motion sickness (P=0.0062) were highly and cardio/cerebrovascular disease (P=0.0015), diabetes (P=0.0001) and renal disease (P=0.0219) were lowly related to ARs. -

CT Venography: Technique and Indications
VENOUS CT Venography: Technique and Indications A brief summary of how to perform indirect and direct CT venography and when this imaging modality can be helpful in diagnosing venous disease. BY ANA MARIJA ALDUK, MD, PHD, AND GERARD O’SULLIVAN, MD T venography (CTV) is not a particularly well- A B validated technique, with most data derived from anecdotal experience. For a variety of reasons, CTV has become the go-to imag- Cing modality for a quick and efficient answer to most venous problems. For example, we work in a trauma center with a large oncology population, and we have learned that oftentimes ultrasound simply doesn’t cut it, particularly in the context of intra-abdominal C D malignancy. Even in very experienced hands, things can be missed. CTV/contrast-enhanced CT provides multiple extra levels of information, including the presence or absence of inferior vena cava (IVC) filters; the condition of the IVC, renal veins, collaterals, and internal iliac veins; potential iliac vein compression or Figure 1. CTPA showing massive bilateral PE (A). Indirect CTV nutcracker syndromes; presence of pelvic varicosities; demonstrates acute IVC thrombosis (B), right external iliac as well as ovarian vein thrombosis and undiagnosed vein scarring due to previous DVT (C), and right common malignancy. femoral vein thrombosis (D). TECHNIQUE A C Indirect CTV Often combined with CT pulmonary angiography (CTPA) in the acute setting, indirect CTV is performed as a standard, nonoral, post–intravenous contrast- enhanced CT at approximately 120 to 150 seconds after injection of contrast, which is considerably later than portal venous phase. -

Bilateral exudative retinal detachment in a patient with cerebral venous sinus thrombosis: a case report Liang Li The second Xiangya Hospital, Central South University Ling Gao ( [email protected] ) Second Xiangya Hospital https://orcid.org/0000-0002-9850-2038 Case report Keywords: exudative retinal detachment, cerebral venous sinus thrombosis, elschnig spot, retinal capillary ischemia Posted Date: June 6th, 2019 DOI: https://doi.org/10.21203/rs.2.9789/v1 License: This work is licensed under a Creative Commons Attribution 4.0 International License. Read Full License Page 1/8 Abstract Background: Cerebral venous sinus thrombosis (CVST) is a rare cerebrovascular disease, it’s ocular symptoms often characterized by a subacute bilateral visual loss, or diplopia and paralysis of eye movements. Fundus examination usually presents as bilateral papilledema and other ocular signs are rare. We report a case of bilateral multiple retinal detachments and nally diagnosed as CVST. Case presentation: A 49-year old woman with progressive headache and bilateral vision deterioration visited our clinic. Ophthaomological examinations including medical history, best-corrected visual acuity, intraocular pressure, slit-lamp biomicroscopy, fundus ophthalmoscopy, uorescein angiography and Optical coherence tomography and head Magnetic Resonance Venogram (MRV) was also performed. Blood tests for ruling out systemic diseases were also performed. Fundus exam revealed bilateral multiple retinal detachment with sub-retinal uid and blurred disc margin. Fluorescein angiography (FA) revealed early hypouorescence in the background stage, multiple pinpoint leakages at the level of retinal pigment epithelium (RPE), and late pooling to outline the boundary of retinal detachment, with some of the leakage shaped as multiple circles in the late stage of FA. -

Magnetic Resonance Angiography (MRA) and Magnetic Resonance Venography (MRV) Medical Policy The content of this document is used by plans that do not utilize NIA review. Service: Magnetic Resonance Angiography (MRA) and Magnetic Resonance Venography (MRV) PUM 250-0027-1712 Medical Policy Committee Approval 12/11/2020 Effective Date 01/01/2021 Prior Authorization Needed Yes Description: Magnetic Resonance Angiography (MRA) and Magnetic Resonance Venography (MRV) use Magnetic resonance imaging (MRI) technology to produce detailed 2-dimensional or 3- dimensional images of the vascular system and may be tailored to assess arteries or veins. It is often used for vascular conditions where other types of imaging are considered inferior or contraindicated, and to decrease risk of cumulative radiation exposure and often instead of invasive procedures. Indications of Coverage: A. MRA/MRV is considered medically necessary for the anatomical regions listed below when the specific indications or symptoms described are documented: 1. Head/Brain: a. Suspected intracranial aneurysm (ICA) or arteriovenous malformation (AVM). Any of the following: 1. Acute severe headache, severe exertional headache, or sudden onset of explosive headache, in individuals with signs / symptoms highly suggestive of a leaking/ruptured internal carotid artery or arteriovenous malformation. 2. Known subarachnoid hemorrhage or diagnosis of spontaneous intracerebral hemorrhage with concern for underlying vascular abnormality. 3. Suspected arteriovenous malformation (AVM) or dural AV fistula in an individual with prior indeterminate imaging study 4. Thunderclap headache with question of underlying vascular abnormality AND prior negative workup to include EITHER i. negative brain MRI, OR ii. Negative brain CT and negative lumbar puncture Page 1 of 15 5. -
Fluorescein and Indocyanine Green Angiography Guidelines ______
Fluorescein and Indocyanine Green Angiography Guidelines _______________________________________________________________________________ Approved by: Board Last reviews: 21 January 2012, 3 June 2015 Approval date: 2007 Next review: 3 June 2018 The Royal Australian and New Zealand College of Ophthalmologists ACN 000 644 404 94-98 Chalmers Street, Surry Hills NSW 2010 Phone: +61 2 9690 1001 Fax: +61 2 9690 1321 www.ranzco.edu Introduction and purpose These Guidelines have been issued by RANZCO for the guidance of ophthalmologists. They should not be used by any other persons or provided to patients as a replacement for medical advice. 1. Fluorescein angiography (FA) is an extremely useful and minimally invasive diagnostic investigation that is frequently performed in ophthalmologists’ private practices and ophthalmology departments. Indocyanine Green (ICG) angiography is a similar but less frequently performed investigation. Despite the generally low risks of the procedure, deaths have occurred during and following FA in both Australia and overseas. General 2. Guidelines in eye care are neither minimal nor aspirational but represent quality eye care commensurate with knowledge as at the date of issue. These Guidelines are based on the best available scientific data and on the collective judgement and evaluation of available evidence by retinal specialists in consultation with medico legal and medical (immunology) colleagues. 3. The Guidelines are for the pattern-of-practice rather than the care of a particular individual. While they may meet the needs of most patients, they cannot possibly meet the needs of all patients. 4. Adherence to these Guidelines will not ensure a successful outcome in every situation and the Guidelines should not be deemed inclusive of all proper methods of care or exclusive of other methods of care reasonably directed at obtaining the best results. -
