Tuberculosis (TB) is an infectious disease of global importance with major economic and social burden accounting for 25% of all avoidable deaths in developing countries. Extrapulmonary involvement may occur either in association with clinically apparent pulmonary tuberculosis or in isolation. This cross-sectional descriptive study aimed to evaluate the impact of ocular tuberculosis in visual acuity at baseline and after two months of intensive anti-tuberculous therapy. A sample of 133 pulmonary TB patients, seven disseminated TB, and three pleural TB patients was evaluated...

Susac's syndrome (SS) is a triad of encephalopathy, branch retinal artery occlusion (BRAO), and sensorineural hearing loss as a result of microvascular occlusions of the brain, retina, and inner ear. It is also a disorder of autoimmune endotheliopathy. SS usually affects young women between the age of 20 and 40 years. SS can be misdiagnosed as multiple sclerosis (MS) or acute disseminated encephalomyelitis (ADEM) because of similar findings. A 15-year-old girl presented in June 2015 with vomiting and severe headache...

BACKGROUND: The critical time from onset of complete occlusion of the central retinal artery (CRA) to functionally significant inner retinal infarction represents a window of opportunity for treatment and also has medical-legal implications, particularly when central retinal artery occlusion (CRAO) complicates therapeutic interventions. Here, we review the evidence for time to infarction from complete CRAO and discuss the implications of our findings. METHODS: A Medline search was performed using each of the terms "central retinal artery occlusion", "retinal infarction", "retinal ischemia", and "cherry red spot" from 1970 to the present including articles in French and German...

Background: We previously reported that pinpoint plantar long-wavelength infrared light irradiation (stress-free therapy; SFT) is useful for alleviating insulin resistance and improving intracranial blood flow in patients with type 2 diabetes mellitus. This study was undertaken to evaluate the influences of SFT on chorioretinal hemodynamics (retinal artery and vein blood flows) as well as atherosclerosis-related factors (TG, LDL-C) and VEGF in patients with dyslipidemia. Methods: Four patients with dyslipidemia received 15-minute irradiation with a stress-free apparatus (far-infrared wavelength, 30 mW)...

Optical coherence tomography angiography (OCTA) is a new, noninvasive technology that enables detailed evaluation of flow in the retinal and choroidal vasculature. The authors believe this to be the first report to describe the optical coherence tomography angiography findings associated with combined central retinal artery occlusion (CRAO) and central retinal vein occlusion (CRVO).

Central retinal arterial occlusion is an ocular emergency. Central retinal artery occlusion following cardiac procedures have been described in adults. We describe a pediatric patient who developed central retinal artery occlusion following pulmonary artery stenting. It is important to highlight this potential risk to ensure early diagnosis and prompt treatment.

Objective: This case report presents a patient with central retinal artery occlusion (CRAO) who was successfully treated with hyperbaric oxygen (HBO₂) but subsequently suffered a recurrence of his visual loss. Methods: CRAO may be treated successfully with HBO₂ if treatment is undertaken promptly after the onset of vision loss. The goal of HBO₂ therapy is to oxygenate the ischemic inner retinal layers via diffusion from the hyperoxygenated choroidal circulation until recanalization of the central retinal artery occurs...

Animal models of disease are an indispensable element in our quest to understand pathophysiology and develop novel therapies. Ex vivo studies have severe limitations, in particular their inability to study individual disease progression over time. In this respect, non-invasive in vivo technologies offer multiple advantages. We here used bilateral common carotid artery occlusion (BCCAO) in mice, an established model for ischemic retinopathy, and performed a multimodal in vivo and ex vivo follow-up. We used scanning laser ophthalmoscopy (SLO), ocular coherence tomography (OCT) and electroretinography (ERG) over 6 weeks followed by ex vivo analyses...

A 25-year-old male patient presented to the emergency department with the chief complaint of sudden blindness and was found to have suffered bilateral central retinal artery occlusion (CRAO). This process is most commonly the result of a thrombus or embolus that occludes the retinal artery, and normally presents in a single eye in patients older than 65 who are predisposed to vascular disease. Diagnosis relies most heavily upon funduscopic exam. Potential treatments involve ocular massage, acetazolamide, anterior chamber paracentesis and systemic or local fibrinolysis...

Excitoneurotoxicity is regarded as one of the mechanisms of the death of retinal ganglion cells induced by retinal central artery occlusion and glaucoma. Oxidative stress is at least in part involved in excitoneurotoxicity. Fenton reaction, which is catalyzed by Fe2+ , is known to cause formation of hydroxyl radical, one of reactive oxygen species, suggesting that chelation of iron may be protective against excitoneurotoxicity. In the present study, we histologically evaluated whether zinc-deferoxamine (Zn-DFO) and deferasirox (DFX), common iron-chelating agents, were protective against N-methyl-D-aspartate (NMDA)-induced retinal injury in the rat in vivo...

Background and purpose: Acute central retinal artery occlusion (CRAO) is a serious ophthalmologic emergency that may result in monocular blindness. To date, studies evaluating intra-arterial thrombolysis (IAT) have not shown a definitive clinical benefit. We have conducted a systematic review with a meta-analysis to effectively evaluate this treatment option. Methods: A systematic literature search was focused on studies containing five or more patients undergoing IAT that included a control group treated with standard therapy...
