Chengfang Li, Rongrong Wang, Guojun Liu, Zhen Ge, Dongdong Jin, Yao Ma, Guixiang Liu
The aim of the present systematic review was to assess the efficacy of laser therapy for ischemic central retinal vein occlusion (CRVO). Relevant studies were retrieved by searching the PubMed, Embase, Chinese Biomedical Literature Database and, Chinese Science and Technology Periodicals databases using a combination of key words, including 'central retinal vein obstruction', 'CRVO', 'laser' and 'panretinal photocoagulation'. The titles, abstracts and full texts were screened by two independent reviewers and studies were selected according to specific inclusion criteria...

RATIONALE: Behcet disease is an autoimmune vasculitis, involving multiple systems and organs. It is often chronic and recurrent, and involves all levels of arteries and veins. PATIENT CONCERNS: A 40-year-old Chinese male with sudden vision loss in his right eye for 3 days was reported. DIAGNOSES: The patient was diagnosed as bilateral uveitis (obstructive retinal vasculitis in the right eye) and Behcet disease. INTERVENTIONS: The patient was given topical corticosteroids and compound tropicamide eye drops in our department...

PURPOSE: Continuous peripheral pulse oximetry for monitoring adequacy of oxygenation is probably the most important technological advance for patients' monitoring and safety in the last decades. Pulse oximetry has the disadvantage of measuring the peripheral circulation, and the only mean to measure oxygen content of the central circulation is by invasive technology. Determination of blood oxyhaemoglobin saturation in the retinal vessels of the eye can be achieved noninvasively through spectrophotometric retinal oximetry which provides access to the central nervous system circulation...

BACKGROUND: Obstructive sleep apnea (OSA) is a common pulmonary disorder with many systemic sequelae. Its association with diseases seen in neuro-ophthalmology is being increasingly recognized. Treatment of OSA with continuous positive airway pressure (CPAP) may reverse the pathology in some eye diseases. EVIDENCE ACQUISITION: We conducted a search of the literature using the Ovid Medline database and Google Scholar, focusing on articles that explored the association between OSA and ophthalmic conditions...

BACKGROUND/AIMS: To study the multimodal imaging findings of a large series of eyes with cilioretinal artery obstruction (CILRAO) and describe the systemic associations. METHODS: Multicentre, retrospective chart review from 12 different retina clinics worldwide of eyes with CILRAO, defined as acute retinal whitening in the distribution of the cilioretinal artery, were identified. The clinical, systemic information and multimodal retinal imaging findings were collected and analysed...

PURPOSE: Evaluate the prevalence of obstructive sleep apnea (OSA) in patients with retinal vein occlusion (RVO). METHODS: A prospective and controlled study including 114 patients from January to September 2016, who were divided into two groups: 69 patients with RVO (RVO+) and 45 controls (RVO-), matched for age, sex and disease. All the patients completed a simple questionnaire and the Epworth Sleepiness Scale and underwent a RUSleeping® (portable monitoring device and then continuously monitored the subject's respiration to detect respiratory events)...

Retinal vein occlusions (RVO) are common retinal diseases. They are caused by an obstruction of retinal veins. RVO often result in visual deterioration and, in rare cases, can lead to blindness, but also be asymptomatic. The prognosis is various and depends on the extent, the localization of the occlusion and the retinal perfusion, especially in the macular area. The etiology often is a thrombosis caused by vascular sclerosis, rarely a vasculitis. Because often an underlying disease is present the medical clarification is necessary...

Purpose: Vascular endothelial growth factor (VEGF) plays an important role in branch retinal vein occlusion (BRVO) with cystoid macular edema (CME). Monitoring changes in VEGF is crucial for evaluating treatment but requires vitreous or aqueous humor sampling, which hampers its clinical application. We investigated the correlation between VEGF and protein concentration in the aqueous humor (flare) and whether this could be used to monitor treatment-related VEGF changes. Design: This retrospective observational study involved 19 previously untreated patients with BRVO...

PURPOSE: Retinal vein cannulation is an experimental procedure during which a clot-dissolving drug is injected into an obstructed retinal vein. However, due to the fragility and minute size of retinal veins, such procedure is considered too risky to perform manually. With the aid of surgical robots, key limiting factors such as: unwanted eye rotations, hand tremor and instrument immobilization can be tackled. However, local instrument anatomy distance and force estimation remain unresolved issues...

AIM: To access the 10-year fundus tessellation progression in patients with retinal vein occlusion. METHODS: The Beijing Eye Study 2001/2011 is a population-based longitudinal study. The study participants underwent a detailed physical and ophthalmic examination. Degree of fundus tessellation was graded by using fundus photographs of the macula and optic disc. Progression of fundus tessellation was calculated by fundus tessellation degree of 2011 minus degree of 2001...

Many associations between ocular disorders and obstructive sleep apnea (OSA) have been studied, such as nonarteritic anterior ischemic optic neuropathy, glaucoma, papilledema, retinal vein occlusion, eyelid hyperlaxity, lower-eyelid ectropion and recurrent corneal erosions. The objective of this review is to synthetize the possible vascular disorders of the retina and the optic nerve associated with sleep apnea patients and to discuss the underlying pathophysiological hypotheses. Main mechanisms involved in the ocular complications of OSA are related to intermittent hypoxia, sympathetic system activation, oxidant stress, and deleterious effects of endothelin 1...

STUDY OBJECTIVES: Obstructive sleep apnea (OSA) incurs a host of systemic side effects. The eyes are particularly susceptible to both mechanical and vascular sequelae of the disease. This paper outlines the ocular manifestations of sleep apnea. The authors hope to increase awareness of the ocular complications of this common disorder and increase communication and co-management between eye-care providers and sleep specialists alike. METHODS: Data were collected from PubMed and the Brown University Library Collection...

Prothrombotic fibrin clot phenotype, involving faster formation of dense meshwork composed of thinner and highly branched fibers that are relatively resistant to plasmin-induced lysis, has been reported in patients with not only myocardial infarction or stroke, but also venous thromboembolism (VTE), encompassing deep vein thrombosis (DVT), and/or pulmonary embolism (PE). Prothrombotic fibrin clot phenotype, in particular prolonged clot lysis time, is considered a novel risk factor for VTE as well as venous thrombosis at unusual location, for example, cerebral sinus venous thrombosis, retinal vein obstruction, and Budd-Chiari syndrome...

PURPOSE: To examine the relationship between both static and dynamic retinal vascular caliber and the severity of obstructive sleep apnea (OSA). DESIGN: Prospective cross-sectional study. METHODS: Adult patients undergoing diagnostic polysomnography studies at a private Australian university teaching hospital were recruited. OSA severity was defined by the apnea-hypopnea index (AHI): severe >30, moderate >15-30, mild 5-15, and controls <5...

BACKGROUND: Obstructive sleep apnea syndrome (OSAS) has been shown to generate hypertension and endothelial dysfunction. Retinal vessel is the only vessel that can be observed directly and noninvasively; retinal vascular abnormalities can serve as a predictive marker for the occurrence, clinical course, and prognosis of cardiovascular and cerebrovascular diseases. The objective of this study was to identify the effect of OSAS severity on the morphological changes of retinal vessels. METHODS: Adult patients complained of snoring were included in this study...

The most serious complication of filler or fat injection is blindness. According to a recent systematic review of 98 patients of blindness provoked by filler or fat injection, only 2 patients had the outcome of a complete recovery of vision.In the literature, only 2 papers were found in which hyperbaric oxygen therapy (HBOT) was used in ophthalmic artery obstruction. However, no improvement of vision was obtained in either patient. Recently, the authors treated a patient who had central retinal vein occlusion and cilioretinal artery occlusion with HBOT (daily 2-hour sessions at 253 kPa for 14 days), and his visual acuity returned to normal...
