Hyaluronic acid (HA) injection is a popular nonsurgical, facial rejuvenating procedure. Due to the rapidly expanding use of HA injections, significant potential complications have also increased in frequency. Among these complications, the rare but most devastating one is arterial occlusion, which can result in skin necrosis or blindness. To describe the mechanisms behind vision loss secondary to hyaluronic acid injection and the efficacy of treatments to restore vision and associated ocular functionality. We reviewed six cases of patients from October 2011 to December 2017 who experienced vision loss after receiving facial HA injections and the subsequent treatments undertaken to attempt to reverse the vision loss and additional eye complications...

Rho-associated coiled-coil containing protein kinase (ROCK) inhibitors are used to treat glaucoma patients and have protective effects on ischemic states. However, it is poorly understood how the ROCK pathway affects the pathological signs of retinal vein occlusion (RVO). In this study, we evaluated the effects of ripasudil, a ROCK inhibitor, on a murine RVO model. In vivo, RVO was induced by retinal vein laser irradiation in mice, and evaluated with ripasudil. In vitro, the effects of ripasudil were examined on tight junction protein integrity in human retinal microvascular endothelial cells (HRMECs)...

Sickle cell disease, the most common genetic disease in the world, is a chronic hemolytic disease that can be complicated by severe vaso-occlusive pain crises resulting in tissue necrosis and even death. Due to its increasing incidence, oral surgeons will inevitably be faced with the management of these patients. To limit the risk of crises, our goal is to share recommendations for the management of sickle cell patients in oral surgery. The vaso-occlusive crises (VOC), heart attacks and chronic anemia endured by these patients cause chronic lesions in various organs...

Cardiac myxomas are benign tumors of endocardial origin that usually occur in the left atrium. Trans-thoracic echocardiography is the diagnostic method of choice, and early surgical removal is the preferred method of treatment. We present a patient whose history of cerebral emboli and central retinal artery occlusion (CRAO) led to a diagnosis of cardiac myxoma. Neuroimaging studies showed multiple infarcts in the region of the left middle and anterior cerebral arteries. Ophthalmic examination showed gross retinal pallor compatible with left central retinal artery occlusion (CRAO)...

Branch retinal vein occlusion (BRVO) may be complicated with retinal ischemia in some cases. The purpose of the current study is to investigate the relationship between optical intensity on optical coherence tomography (OCT) and retinal ischemia in BRVO. Twenty-seven eyes diagnosed with BRVO without macular edema were classified into two groups based on the presence or absence of retinal ischemia. The optical intensity of inner retinal layers and photoreceptor inner segment ellipsoid zone/retinal pigment epithelium layer (ISe/RPE) in the affected and unaffected regions were measured on OCT...
