Surgical management of acute angle-closure glaucoma after toric implantable contact lens implantation
2006
A case of pupillary block after implantation of an implantable contact lens (ICL) is reported, and surgical management and prevention are discussed. In a myopic patient, the best corrected visual acuity in the right eye was 20/50 with -15.50 -3.00 x 175. After uneventful implantation of an ICL, painful acute glaucoma developed with an intraocular pressure beyond measurable values. Apparent anterior vaulting of the ICL suggested a sizing problem. In a situation of a mid-wide dilated pupil, immediate explantation of the ICL was performed. Then, using a preoperative iris photography as guidance, an anterior chamber iris-claw toric phakic intraocular lens was implanted. On postoperative examina…
Role of nitric oxide synthase isoforms for ophthalmic artery reactivity in mice.
2014
Abstract Nitric oxide synthases (NOS) are involved in regulation of ocular vascular tone and blood flow. While endothelial NOS (eNOS) has recently been shown to mediate endothelium-dependent vasodilation in mouse retinal arterioles, the contribution of individual NOS isoforms to vascular responses is unknown in the retrobulbar vasculature. Moreover, it is unknown whether the lack of a single NOS isoform affects neuron survival in the retina. Thus, the goal of the present study was to examine the hypothesis that the lack of individual nitric oxide synthase (NOS) isoforms affects the reactivity of mouse ophthalmic arteries and neuron density in the retinal ganglion cell (RGC) layer. Mice defi…
Dynamics, alterations, and consequences of minimally invasive intraocular pressure elevation in rats.
2014
PURPOSE: An important, yet not exclusive, aspect of primary open angle glaucoma is elevated intraocular pressure (IOP) profiles within fluctuations and pressure peaks. The study aimed at establishing minimally invasive methods for recurrent IOP elevation in rats to investigate the impact of IOP dynamics and pathomorphologic retinal alterations during and after IOP elevation. METHODS: Intraocular pressure was elevated unilaterally in Long Evans rats to a level of ≈35 mm Hg for 1 hour in a total of 30 manipulations within 6 weeks, by using two methods: (1) suction-cup oculopression and (2) loop-adjusted oculopression. Retinal thickness (RT) was measured via optical coherence tomography (OCT),…
The cremation structures of the Roman Empire: anthracological data versus historical sources
2011
ISSN: : 0210-3729; International audience; During the excavation of the Roman necropolis site Richeaume (Bouches-du-Rhone, Provence, France), cremation primary structures have been identified. A specific protocol consisting in collecting the entire sediment for sampling charred funeral remains on a grid of 20 to 40 cm, was systematically experimented and put into practice. The first anthracological results offer a reading of both qualitative and quantitative spatial residues of the cremation (including the discovery of the ignition lock, and technical aspects revealing a specific choice adapted to the practice of cremation). This reading led to interpret anthracological results in a technic…
Intraocular lens centration and stability: efficacy of current technique and technology
2008
Purpose of review The manuscript presents a review of recently published studies analyzing different methodologies to assess centration and stability of intraocular lenses after implantation. Recent findings Considering that there is no current gold standard for centration and stability of intraocular lenses after implantation, we have summarized the different techniques used clinically for intraocular lenses centration and stability estimation. We have described the use of Scheimpflug imaging, the anterior segment optical coherence tomography and photography analysis used for lens position estimation. Techniques used to assess lens rotation are based on image analysis on digital retroillum…
Variazione della pressione intraoculare durante le procedure diagnostiche endoscopiche
2012
Obiettivo. Obiettivo del presente studio è stato quello di rilevare qualsiasi possibile variazione nella pressione intraoculare (PIO) in soggetti non glaucomatosi sottoposti a esami endoscopici come la gastroscopia o la colonscopia, al fine di valutare il ruolo della tensione mentale in tali cambiamenti. Metodi. La frequenza cardiaca e il tono oculare sono stati misurati prima e subito dopo le procedure endoscopiche e 30’ dopo la somministrazione di un antagonista delle benzodiazepine in 100 soggetti, 52 uomini e 48 donne, sottoposti a gastroscopia, colonscopia o entrambi gli esami nella stessa occasione. Risultati. La frequenza cardiaca è diminuita da 82,10±14,41 a 76,11±10,96 30’ dopo la …

Is Ranibizumab effective in stopping loss of vision secondary to Choroidal Neovascularization in Pathologic Myopia? A Long Term Follow-up Study.
2011
Purpose: To assess the efficacy and safety of Ranibizumab in the treatment of choroidal neovascularization (CNV) caused by pathologic myopia (PM). Design: Prospective, multicenter, interventional case series. Methods: 40 of 39 consecutive patients with PM and CNV were treated with “on-demand” intravitreal injection of ranibizumab 0.5 mg. Final best-corrected VA (BCVA) and its change from baseline were the main outcome measures. Changes in Optical Coherence Tomography (OCT) central retinal thickness (CRT) were a secondary outcome. Results: Mean age was 53 ± 13 years, mean refractive error -13.5 ± 6.5 diopters. Median follow-up was 13.3 ± 2 months (range 12 – 18). Fifteen eyes (37.5%) had pre…
Du vin au cacao : enjeux des sources et des méthodes pour une sémantique sensorielle
2018
Ce cours, proposé dans le cadre du séminaire du Professeur Eva Lavric à l’Université d’Innsbruck (Autriche), vise à discuter les enjeux, voire les défis, liés à une description linguistique, et surtout sémantique, du cacao. Ce faisant, il touche à la méthodologie d’une « linguistique sensorielle/de la sensorialité » dont il commence par présenter l’objet et la/les problématique(s), en particulier à travers la nécessité d’opter pour des paradigmes constructivistes de description du sens. Il s’arrête ensuite sur les acquis actuels dans la description de la langue du vin, en particulier de sa terminologie, en mettant en avant les manques de fondement théorique des roues des arômes, pourtant tr…
