A 55-year-old woman developed no light perception vision in her right eye 5 days after an injection of polylactic acid cosmetic filler into her right forehead. Diffuse corneal edema and anterior chamber inflammation prohibited any view to the posterior segment to identify the cause of her profound vision loss. MRI of the orbits with diffusion-weighted imaging showed hyperintensity of the right optic nerve with signal reduction on apparent diffusion coefficient mapping, consistent with ischemia. Our patient also was found to have acute infarctions in the distribution of the right anterior cerebral artery on MRI of the brain despite having no permanent focal neurologic deficits aside from vision loss...

PURPOSE: Comparison of the demographic, ocular, systemic and microbiological characteristics of eyes with bleb related infection (BRI) and bleb related endophthalmitis (BRE). METHODS: Retrospective chart review of patients with BRI from January 1996-July 2013. Identification done via the center's longstanding endophthalmitis audit, BRI audit and laboratory database identifying all conjunctival swabs from blebs. Blebitis was defined as anterior segment inflammation with mucopurulent material in or around the bleb, with anterior chamber cells but no hypopyon...

«Minimally invasive» techniques have been recently been developed in order to achieve good clinical results with a low incidence of complications. The extralateral interbody fusion or direct transpsoas is a minimally invasive anterior arthrodesis. A total of 97 patients with 138 segments received surgery between May 2012 and May 2015. The follow-up was from 12-44 months. The mean age was 68 years (41-86). The most common cause of intervention was the adjacent segment (30%), deformity (22%), and lumbar disc disease (21%)...

Purpose: To investigate the ocular immune response following exposure to airborne titanium dioxide (TiO2) microparticles. Methods: Rats in the TiO2-exposed group (n = 10) were exposed to TiO2 particles for 2 hours twice daily for 5 days, while the controls (n = 10) were not. Corneal staining score and tear lactic dehydrogenase (LDH) activity were measured to evaluate ocular surface damage, serum immunoglobulin (Ig) G and E were assayed by using enzyme-linked immunosorbent assay, and the size of cervical lymph nodes was measured...

BACKGROUND: Accurate visual assessment of wall motion during dobutamine stress echocardiography (DSE) requires expertise; strain stress echocardiography thus has potential for the objective and reliable evaluation of stress-induced wall motion abnormalities. The aim of this study was to test the hypothesis that strain imaging also requires expertise. Diagnostic accuracy for significant coronary artery disease was compared between visual and strain analysis with a bull's-eye map, and the effect of expertise on readers' accuracy during DSE was determined...

BACKGROUND: Laser is the gold standard for treatment of retinopathy of prematurity (ROP). CASE CHARACTERISTICS: A preterm baby born at 26 weeks gestation age with bilateral aggressive posterior ROP had bilateral total cataract after laser treatment. OUTCOME: Uneventful cataract surgery.

The thalamus plays an important role in signal relays in the brain, with thalamocortical (TC) neuronal pathways linked to various sensory/cognitive functions. In this study, we aimed to see fetal and postnatal development of the thalamus including neuronal migration to the thalamus and the emergence/maturation of the TC pathways. Pathways from/to the thalami of human postmortem fetuses and in vivo subjects ranging from newborns to adults with no neurological histories were studied using high angular resolution diffusion MR imaging (HARDI) tractography...

AIM: To analyze changes in various biometric parameters after vitrectomy. MATERIAL AND METHODS: A total of 50 patients (50 eyes) were followed up. All of them underwent vitrectomy for idiopathic epiretinal fibrosis and macular hole. In addition to the standard ophthalmic examination, we performed a combined ultrasound study and ultrasound biomicroscopy before and after the surgery (at 2-3 weeks and 6 months). Variation statistics was applied to assess the results using the SPSS Statistica 20 software...

BACKGROUND: Multivessel disease (MVD) is a significant risk factor in patients with acute ST-segment elevation myocardial infarction (STEMI). Whether the presence of chronic total occlusion (CTO) poses an additional hazard is still unknown. The objective of this study was to evaluate the impact of CTO on survival in STEMI patients. METHODS: The study group consisted of 836 STEMI patients treated with primary percutaneous coronary intervention (PCI). MVD was diagnosed in 52...

Collateral circulation is a key variable determining prognosis and response to recanalization therapy during acute ischemic stroke. Remote ischemic perconditioning (RIPerC) involves inducing peripheral ischemia (typically in the limbs) during stroke and may reduce perfusion deficits and brain damage due to cerebral ischemia. In this study, we directly investigated pial collateral flow augmentation due to RIPerC during distal middle cerebral artery occlusion (MCAo) in rats. Blood flow through pial collaterals between the anterior cerebral artery (ACA) and the MCA was assessed in male Sprague Dawley rats using in vivo laser speckle contrast imaging (LSCI) and two photon laser scanning microscopy (TPLSM) during distal MCAo...

AIM: To evaluate the performance of apparent diffusion coefficient (ADC) mapping compared with voxel-based morphometry and to demonstrate the clinical usefulness of ADC mapping in the diagnosis of Alzheimer's disease (AD). MATERIALS AND METHODS: The study population comprised 31 patients with AD (group A) and 24 patients without dementia (group B) who underwent three-dimensional (3D) T1-weighted imaging (WI) and two-dimensional (2D) echo-planar diffusion-weighted imaging (DWI) at 3 T...

BACKGROUND: As a systemic disease, atherosclerosis commonly affects intracranial and extracranial carotid arteries simultaneously which is defined as co-existing plaques. Previous studies demonstrated that co-existing atherosclerotic diseases are significantly associated with ischemic cerebrovascular events. The aim of this study was to investigate the characteristics of co-existing intracranial and extracranial carotid atherosclerotic plaques and their relationships with recurrent stroke by using 3D multi-contrast magnetic resonance (MR) vessel wall imaging...

BACKGROUND: Myocardial infarction (MI) is the leading cause of death in Iran. Every attempt to improve treatment patterns and patient outcomes needs a surveillance system to both consider the efficacy and safety measures. Fasa Registry on Myocardial Infarction (FaRMI) is the first population-based registry for acute MI in Iran targeted to provide meticulous description of patients' characteristics, to explore the management patterns of these patients, to discover the degree of adherence to the practice guidelines, and to investigate the determinants of poor in-hospital and later outcomes...

PURPOSE: Intraocular pressure (IOP) elevation occurs regularly after Descemet membrane endothelial keratoplasty (DMEK). This study evaluated the effect of central corneal thickness (CCT) on the IOP after DMEK. PATIENTS AND METHODS: This prospective study recorded the IOP of 46 eyes from 46 patients preoperatively, and then 1 and 3 months after DMEK. IOP measurement was performed by noncontact pneumatic tonometry (NCT), iCare, Goldmann applanation tonometry (GAT), and dynamic contour tonometry (DCT)...

BACKGROUND: This prospective clinical case series aimed to investigate the safety of subretinal adipose tissue-derived mesenchymal stem cell (ADMSC) implantation in advanced stage retinitis pigmentosa (RP). METHODS: This study included 11 patients with end-stage RP who received subretinal implantation of ADMSCs. All patients had a total visual field defect and five of them only had light perception. The best corrected visual acuity (BCVA) in the study was 20/2000...

BACKGROUND: To examine the influence of posterior corneal astigmatism on postoperative refractive astigmatism in pseudophakic eyes after cataract surgery. METHODS: The study enrolled 64 pseudophakic eyes of 50 patients (71.8 ± 9.9 years old, mean ± standard deviation) who had undergone phacoemulsification with non-toric IOL implantation. Refractive astigmatism was measured using an auto ref-keratometer with a 0.01- diopter (D) scale. Two types of corneal astigmatism were calculated using anterior segment optical coherence tomography; keratometric and total corneal astigmatism...
