Endophthalmitis can be a devastating complication after cataract surgery. Therefore, this study sought to better understand the occurrence rate of acute-onset postoperative endophthalmitis after cataract surgery in Chinese small and medium-scale departments of ophthalmology, as well as identify its risk factors and assess the treatment options. This investigation revealed 52 postoperative endophthalmitis cases in 46,185 operations at 30 hospitals from 2011 to 2013, at an occurrence rate of 0.11%. A small cataract surgery volume of less than 500 cases per year (OR 2...

BACKGROUND Central retinal artery occlusion (CRAO) is the occlusion of the central retinal artery resulting in retinal infarction and acute vision loss. Digital subtraction angiography (DSA)-guided superselective ophthalmic artery or selective carotid thrombolysis remains the preferred treatment method for CRAO. This study aimed to evaluate the safety and clinical efficacy of the novel ophthalmic artery branch retrograde thrombolytic intervention for CRAO. MATERIAL AND METHODS Fifty patients with monocular CRAO were enrolled, including 28 males and 22 females (mean age: 55...

BACKGROUND: Acute symptoms of dizziness and/or imbalance commonly experienced in athletes postconcussion are speculated to arise from dysfunction at multiple levels (i.e., inner ear or central vestibular system) to appropriately integrate afferent sensory information. Disruption along any pathway of the balance system can result in symptoms of dizziness, decreased postural control function (vestibulospinal reflex), and reduced vestibulo-ocular reflex function. This may also lead to decreased gaze stability with movements of the head and may account for symptoms of blurred vision or diplopia reported in almost half of athletes sustaining a concussion...

PURPOSE: To determine the relationship between different spectral domain optical coherence tomography (SD-OCT) signs of retinal ischemia in acute central retinal vein occlusion (CRVO) and whether they predict anterior segment neovascularization (ASNV). DESIGN: Retrospective, observational study. SUBJECTS: Thirty-nine consecutive patients with acute CRVO and 12 months of follow-up. METHODS: We graded baseline SD-OCTs for increased reflectivity of the inner retina, loss of definition of inner retinal layers, presence of a prominent middle-limiting membrane (p-MLM) sign, and presence of paracentral acute middle maculopathy (PAMM)...

INTRODUCTION: Natural orifice transluminal endoscopic surgery (NOTES) is a challenging minimally invasive procedure. Although laparoscopic techniques for liver resection are gaining acceptance worldwide, few studies have investigated NOTES liver resection. We used a porcine model to assess the feasibility and safety of transvaginal NOTES liver resection (TV NOTES LR). MATERIALS AND METHODS: Nine female pigs underwent TV NOTES LR. A nonsurvival acute porcine model with general anesthesia was used in all cases...

The causes of posterior uveitis can be divided into infectious, autoimmune, or masquerade syndromes. Viral infections. a significant cause of sight-threatening ocular diseases in the posterior segment,, include human herpesviruses, measles, rubella, and arboviruses such as dengue, West Nile, and chikungunya virus. Viral posterior uveitis may occur as an isolated ocular disease in congenital or acquired infections or as part of a systemic viral illness. Many viruses remain latent in the infected host with a risk of reactivation that depends on various factors, including virulence and host immunity, age, and comorbidities...

BACKGROUND: Acute-onset postoperative endophthalmitis after cataract surgery remains a rare but important cause of visual loss. There is no global consensus regarding the optimal strategies for prophylaxis of endophthalmitis and practices vary substantially around the world, especially with respect to the use of intracameral antibiotics. The European Society of Cataract & Refractive Surgeons in a randomized clinical trial (2007) reported an approximately 5-fold reduction in endophthalmitis rates associated with the use of intracameral cefuroxime...

A 49-year-old female victim of violent crime with an acute bilateral loss of vision was referred to our hospital. The ophthalmological evaluation showed complete subconjunctival hemorrhage of both eyes, bilateral hemophthalmos and hypotonia of the left eye. These raised the suspicion of an occult scleral rupture. We immediately performed exploratory surgery and found a perforating scleral lesion of the left eye and a penetrating scleral lesion of the right eye. Furthermore, a small, cruciform wound was detected on the left temple...

Intermediate uveitis is described as inflammation in the anterior vitreous, ciliary body and the peripheral retina. It is a subset of uveitis where the vitreous is the major site of damage. It has been reported to be associated with many local and systemic inflammatory and infectious diseases. An infrequent cause is the tubulointerstitial nephritis and uveitis syndrome. We report a case of an acute visual acuity loss related with renal failure in a 64 years old woman with Hashimoto disease. It was an acute tubulointerstitial nephritis and uveitis syndrome case...

BACKGROUND: Ischemic arterial strokes of the ophthalmic artery and its branches and posterior cerebral artery are common causes of visual disability. Etiologies of stroke affecting the retina, optic nerve, optic radiation, and visual cortex overlap with other types of ischemic strokes. Stenosis of the internal carotid is the most common cause of central retinal artery occlusion (CRAO). One-fourth of patients with CRAO have cerebral strokes. We report recent developments in the acute treatment and secondary prevention of ischemic stroke of relevance to clinicians who encounter patients with acute vision loss...

Our aim is to report 13 unusual cases of acquired, temporal sectoral scotomas. Such stationary "wedge" field defects have been reported previously in cases of presumed congenital nasal hypoplasia of the optic disc and as a complication of vitreoretinal surgery. To our knowledge, the literature provides no reports of similar defects occurring spontaneously. This is a descriptive clinical case series of 13 patients presenting with sub-acute monocular temporal visual field loss. All were clinically assessed and investigated with Goldmann perimetry, automated Humphrey visual fields, retinal optical coherence tomography, orbital ultrasound, and standard and multi-focal electroretinography...

OBJECTIVES: Cognitive dysfunction from high altitude exposure is a major cause of civilian and military air disasters. Pilot training improves recognition of the early symptoms of altitude exposure so that countermeasures may be taken before loss of consciousness. Little is known regarding the nature of cognitive impairments manifesting within this critical window when life-saving measures may still be taken. Prior studies evaluating cognition during high altitude simulation have predominantly focused on measures of reaction time and other basic attention or motor processes...

BACKGROUND: Uncoupling protein 2 (UCP2) has been suggested to inhibit mitochondrial production of reactive oxygen species (ROS) by decreasing the mitochondrial membrane potential. Experimental acute pancreatitis is associated with increased UCP2 expression, whereas UCP2 deficiency retards regeneration of aged mice from acute pancreatitis. Here, we have addressed biological and molecular functions of UCP2 in pancreatic stellate cells (PSCs), which are involved in pancreatic wound repair and fibrogenesis...
