L'aspirine n'est pas un facteur de risque de complications hémorragiques pendant et après une première chirurgie de décollement de rétine rhegmatogène by Eva Zaratzian Brillat( )

2 editions published in 2011 in English and held by 3 WorldCat member libraries worldwide

Objective: To evaluate the hemorrhagic risk of treatment by acetylsalicylic acid, during the management of primary rhegmatogenous retinal detachment (RD). Design: case-control study (according to presence of perioperative bleeding complications). Participants: 322 patients (322 eyes) from a prospective cohort of 835 patients with primary rhegmatogenous RD operated on between 2004 and 2007. Methods: After exclusion of patients with RD secondary to trauma, subjects with a history of vitreoretinal surgery, diabetic retinopathy, aphakia or taking clopidogrel and/or a vitamin K antagonist, 74 patients were included in the hemorrhagic group and patients without hemorrhagic complications were randomly selected in order to reach a 1:3 case: control population. Univariate and multivariate analyses were performed to identify risk factors of perioperative bleeding. Main outcome measures: Occurrence of hemorrhagic complications such as hyphema and intravitreal, subretinal and suprachoroidal hemorrhage. Prognostic factors included final visual acuity (LogMAR) and the single-operation attachement rate. Results: Univariate analysis showed that the presence of initial vitreous hemorrhage, size of breaks, number of breaks, pars plana vitrectomy (PPV) and the number of cryotherapy impacts were significantly associated with perioperative bleeding. Independent risk factors of perioperative hemorrhage were the number of cryotherapy sessions (odds ratio =1.12 [1.06; 1.20], 95% CI), transscleral drainage (OR =4.22 [1.62; 10.98]), and PPV (OR =3.39 [1.36; 8.47]). The occurrence of bleeding complications was associated with a lower single-operation anatomical success rate. There was also a trend toward an association between bleeding complications, the total number of RD recurrences, and final visual acuity. Conclusion: Aspirin was not an independent risk factor of hemorrhagic complications during and after surgery of primary rhegmatogenous RD. The bleeding risk is instead associated with surgical factors such as PPV, cryotherapy, and subretinal fluid drainage
Optic-nerve-head blood-flow response to increase in arterial blood pressure in humans by Tiffany Lacharme( )

2 editions published in 2011 in English and held by 3 WorldCat member libraries worldwide

Purpose. Autoregulation in ocular tissues ensures constant blood flow despite variations in ocular perfusion pressure and may be impaired in ocular diseases. The purpose of this study was to investigate the effect of increased blood pressure (BP) and ocular perfusion pressure (OPP) during isometric exercise on optic-nerve-head blood flow (ONH-BF). Methods. In 21 healthy subjects, aged 18-40 years, BP was measured using a Nexfin™ pneumatic transcutaneous sensor and blood flow was measured using laser Doppler flowmetry (LDF). OPP was defined as (0.74 × mean BP) - intraocular pressure. Handgripping consisted of static contraction of the finger flexors at 30% maximum contraction force using a hand dynamometer for 2 min. Results. Data were analyzed in 15 healthy subjects, exhibiting a homogeneous response of BP to handgripping (linear regression of BP versus time). A large increase, up to 50%, in OPP during exercise was not associated with a proportional increase in ONH-BF; vascular resistance increased about 30%. The blood flow-pressure relationship showed blood flow significantly increased by approximately 30%, mainly due to the rise in velocity. Conclusion. These new data strongly support the notion of autoregulation in ocular blood flow, protecting the eye from overperfusion. However, the increase in OPP is not completely counterbalanced despite the regular increase in vascular resistance. This blood flow regulation is possibly due to vasoconstriction, taking place outside of the sampled volume, probably in the arterioles proximal to the capillary bed of the neuroretinal rim. In the future, real-time measurements of vascular resistance during handgripping could be investigated in glaucoma patients
Les pseudo-tumeurs inflammatoires idiopathiques de l'orbite by Jean-Paul Romanet( )

3 editions published between 1979 and 2017 in French and held by 3 WorldCat member libraries worldwide

Nous avons rapporté huit observations de pseudo-tumeurs inflammatoires idiopathiques de l'orbite. Bien que toutes caractéristiques, elles se sont avérées très différentes par leur tableau clinique paraclinique et éventuellement histologique, par leur évolution, par les problèmes diagnostiques et thérapeutiques qu'elles ont pu poser. A la lumière des éléments fournis par ces observations et à l'aide des données de la littérature, nous avons analysé les aspects cliniques variés mais souvent trompeurs des pseudo-tumeurs inflammatoires, après avoir estimé leur fréquence à 1 pseudo-tumeur inflammatoire pour 9 tumeurs orbitaires vraies environ. Nous avons décrit ensuite les diverses investigations paracliniques susceptibles d'étayer au mieux le diagnostic, en particulier l'échographie orbitaire et la tomodensitométrie. Après avoir envisagé les trois modalités évolutives de l'affection, nous avons insisté sur quelques formes cliniques, formes anatomo-cliniques mais aussi formes de l'enfant et pseudo-tumeurs associées à des lésions fibro-scléreuses extra-orbitaires. Lors de l'étude diagnostique, nous nous sommes efforcés de sélectionner un certain nombre d'arguments paracliniques, notamment tomodensitométriques, qui nous ont paru suffisamment fiables pour que leur réunion permette d'établir le diagnostic de pseudo-tumeur inflammatoire, le recours à l'étude histologique restant indispensable dans les cas non probants. Nous avons discuté, comme diagnostic différentiel, les tumeurs orbitaires et les exophtalmies endocriniennes, avant d'évoquer le syndrome de Tolosa-Hunt, forme frontière de l'affection, et les pseudo-tumeurs inflammatoires avec étiologie connue. Enfin, après une description analytique du traitement, nous avons tenté de codifier une attitude thérapeutique pratique qui repose sur la corticothérapie associée dans des cas bien précis à l'exérèse chirurgicale. Cette affection comporte encore des ambigüités indéniables, ce qui justifie parfaitement l'intérêt que de très nombreux auteurs lui ont porté. On peut espérer que l'éclaircissement futur de la pathogénie permettra l'élaboration d'une définition satisfaisante et surtout lèvera les dernières difficultés des chapitres diagnostique et thérapeutique qui, à notre avis, semblent avoir bénéficié de façon très appréciable des progrès permis par la tomographie axiale computérisée

Autofluorecence dans la choriorétinopathie de Birdshot by Rachel Semecas( )

1 edition published in 2016 in English and held by 2 WorldCat member libraries worldwide

Purpose: To characterize and correlate the different patterns of fundus autofluorescence (FAF) in patients with Birdshot chorioretinopathy (BSCR), with functional and anatomical parameters. Methods: 21 BSCR patients were prospectively studied in 2013 and 2014. Each patient underwent visual acuity (VA) and visual field (SITA standard 30.2) testing as well as fluorescein and indocyanine green angiography, spectral-domain optical coherence tomography (SD-OCT) B scan, and enhanced depth imaging (EDI), and fundus autofluorescence (FAF) imaging. The disease was classified as active, chronic, or quiescent. Results: The patients' mean age was 60.3±9.2 years and 60% were female. Disease duration was 5.7±3.7 years. Autofluorescence imaging showed punctiform hyper-FAF spots in 23 out of the 29 eyes (79%), which was significantly associated with a larger visual field mean defect ( -7±7 versus -3±2 dB, p=0.04). Hypo-FAF was defined as peripapillary (n=25; 86.2%), macular (n=10; 34.5%), lichenoid (n=17; 58.6%), and/or diffuse (n=13; 44.8%). Lichenoid hypo-FAF was significantly associated with worse VA (0.18±0.24 vs 0.05±0.07 LogMAR, p=0.04). Macular hypo-FAF was associated with a history of macular edema (62.5%; p=0.06). Diffuse hypo-FAF was observed more frequently (p=0.01) in chronic disease (66.7%) than in active (0%) or quiescent disease (27.3%). Conclusion: Autofluorescence analysis in BRSC patients contributes to evaluating disease activity and could be useful to guide follow-up and treatment
Longitudinal study of retinal status using optical coherence tomography after acute postcataract endophthalmitis by Thierry Zhou( )

1 edition published in 2014 in English and held by 2 WorldCat member libraries worldwide

Purpose: to analyze the macular microstructure imaged by Optical Coherence Tomography (OCT) in patients treated for postcataract endophthalmitis. Methods: All patients presenting with an acute post cataract surgery endophthalmitis were included in this prospective, observational and multicenter study from 2008, January to 2013, December. Exclusion criterias were every other cause of endophtalmitis, past history of macular disease and missed OCT follow-up at month 3, 6 or 12. A Time Domain (TD) or Spectral Domain (SD) OCT was performed at each visit after a full clinical examination. A standardized analysis was assessed for each OCT and recorded for statistical analysis. Results: 106 patients were included in this protocol; 46 patients with a regular follow-up were included for the OCT analysis. Bacterial identification was performed in 67% out of the cases, and virulent bacteria were noted in 13%. We found an increase in epiretinal membrane (ERM) over time of 26% to 39%, a prevalence of 6.5% to 13% of non-tractional macular edema (ME) and 10% of macular atrophy (MA). At Month 12, a significant correlation was found between non-tractional ME and occurrence of perioperatory complications (p=0.03). ERM was significantly associated with the presence of hypopion at presentation (p=0.001) and a significant difference in comparison to normal macula, was found in LogMAR visual acuity (VA, p=0.02), Central macular thickness (p=0.001) and good final VA (≥20/40, p=0.04). Microstructural OCT analysis of the outer retina layer showed a significant association between ERM and alteration of the ellipsoid band (p=0.02), or of the MLE (p=0.07) at M12. Conclusion: ERM and ME are the main macular abnormalities diagnosed after one year of follow-up with a good prognosis in final visual acuity. OCT remained essential for macular analysis and early complications diagnosis and treatment

Effects of glaucoma medications on long-term diurnal intraocular pressure variations by Georges Zaatar( )

1 edition published in 2015 in English and held by 2 WorldCat member libraries worldwide

Purpose: To evaluate the effects of glaucoma medications on the long-term diurnal intra-ocular pressure (IOP) variations in patients with primary open angle glaucoma (POAG).Design: Database analysis. Participants: One hundred forty-eight patients with POAG naïve from any glaucoma surgery and treated with a topical monotherapy of ocular hypotensive drug (beta-blocker, prostaglandin, carbonic anhydrase inhibitor or adrenergic agonist). Methods: We retrospectively reviewed the records of patients who underwent 3 diurnal IOP curve measurements 6 months apart with Goldmann aplanation tonometry recorded in the sitting position at 9 AM, 10 AM, 11 AM, Noon, 2 PM, 3 PM, 4 PM and 5 PM.Main outcome measures: Intervisit agreement of IOP by time point and of diurnal IOP curve parameters (mean, standard deviation, range, maximum, minimum, maximum hour, minimum hour) was assessed using the intraclass correlation coefficients (ICCs). When both eyes were eligible one eye was randomly chosen for analysis.Results: Sixty five patients were treated with prostaglandin analogs (PG), 38 with beta-blockers (BB), 23 with carbonic anhydrase inhibitor (CAI) and 22 with adrenergic agonists (AA). In all subjects with monotherapy, between-visit agreement of IOP values at each time point was generally poor, with ICCs ranging from 0.43 to 0.81 (3 time points out of 8 with ICCs > 0.75). In subjects treated with PG, we found better between-visit agreement of IOP values, with ICC ranging from 0.51 to 0.85 (6 time points out of 8 with ICCs > 0.75). In subjects treated with BB, CAI and AA, between-visit agreement of IOP values was generally poor, with ICCs ranging from 0.44 to 0.79 (3 time points out of 8 with ICCs > 0.75), from 0.51 to 0.78 (2 time points out of 8 with ICCs > 0.75), and from 0.29 to 0.77 (3 time points out of 8 with ICCs > 0.75), respectively. Conclusion: POAG patients with monotherapy usually do not manifest a repeatable diurnal IOP pattern from months to months. Only patients treated with PG exhibit better long-term repeatable diurnal IOP patterns
The bright spot sign : a new MR morphological sign to early diagnose arteritic anterior ischemic optic neuropathy due to giant cell arteritis by Perrine Remond( )

1 edition published in 2017 in English and held by 2 WorldCat member libraries worldwide

Purpose: A rapid determination of the anterior ischemic optic neuropathy (AION) etiology is crucial as it determines the therapeutic management. In this study, we assess MRI to study the optic nerve head in patients referred with AION either due to giant cell arteritis (GCA-AION), or due to the nonarteritic form of the disease (NA-AION), compared with healthy subjects. Methods: Fifteen patients with GCA-AION and 15 patients with N-AION were prospectively included from May 2015 to January 2016 in two medical centers. Healthy subjects and patients had undergone a contrast-enhanced, flow-compensated, 3DT1-weighted MRI scan. Bright spot sign was defined by a local optic nerve head enhancement in a three-point scale. The bright spot sign was defined as an optic nerve head enhancement using a three-grade ranking system. Two radiologists and one ophthalmologist independently performed blind evaluations of MRI sequences using this scale. Statistical analysis included inter-observer agreement. Results: MR imaging scores were significantly higher in patients with GCA-AION than in patients with NAION (pd".05). The bright spot sign was observed in all patients (15/15) with GCA-AION and in 7/15 patients with AION. In healthy subjects, no enhancement of the anterior part of the optic nerves including the optic nerve head was observed. There was a significant relationship between the side of the bright spot and the side of the AION (pd"0.001). The inter-reader agreement was good for observers (k= 0.815). Conclusion: AION is an ocular emergency, in context of GCA that requires early diagnosis and immediate treatment to prevent further visual loss. In this study, we provide evidence for a new MRI sign that identifies the acute stage of GCA-AION, the bright spot sign was observed in all patients with GCA. In contrast, patients without the bright spot sign always presented with a non-arteritic pathophysiology and therefore did not require emergency corticosteroid therapy
Monitoring of visual field over six months after active ocular toxoplasmosis by J Blot( )

1 edition published in 2017 in English and held by 2 WorldCat member libraries worldwide

Purpose: To prospectively report the perimetric defects during a six-month follow-up (FU) in patients with initially active ocular toxoplasmosis (OT). Methods: Twenty-four patients were studied, including 11 eyes with a chorioretinal toxoplasmosis proven with a positive aqueous humor sample and 13 eyes with a typical chorioretinal lesion biologically unproven. Kinetic perimetry with visual fields 24-2 were performed at baseline, first month and sixth month of FU and all parameters were noted. A composite clinical severity score was calculated from visual acuity (VA in LogMAR), severity of vitritis, chorioretinal lesion size, a localization of the lesion in zone 1, the presence of an initial macular or papillary edema and a long-time scarring. This permitted to have a relative cut-off level of severity. Nine eyes were considered like severe OT among the 24 included eyes. Results: Initial and final visual field parameters (MD and PSD) were strongly correlated in all OT. During FU, only FT was correlated with VA. MD initial predictive value of severity was 0.739 according to ROC curve. At baseline, at the first month and at the sixth month, none parameter showed a significant difference between severe and non-severe OT, whereas each parameter considered during complete FU related a significant difference (MD, p=0.0118; PSD, p=0.05; VFI, p=0.016 and FT, p=0.021). Conclusion: Visual field parameters better contextualized the chorioretinal destruction related to toxoplasmosis lesion and the functional repercussions than visual acuity alone. Interestingly, MD could be a discriminating factor of severity in active OT, and each visual field parameter follow-up could be a support to manage patients with active OT. Our study suggested an original clinical score of severity in this most frequent form of posterior uveitis in the world
Specific PCR and quantitative real time PCR in ocular samples from acute and delayed-onset post operative endophthalmitis by Julie Kosacki( )

1 edition published in 2016 in English and held by 2 WorldCat member libraries worldwide

Objective: To evaluate the contribution of specific PCR targeting S. aureus and S. pneumonia for the identification of these species and the quantitative PCR for endophthalmitis due to S. epidermidis in ocular samples from patients with acute or delayed-onset post-operative endophthalmitis. Methods: 153 consecutive patients presenting with acute or delayed-onset postoperative endophthalmitis were included in three university hospitals between 2008 and 2016. A total of 284 ocular samples were obtained from aqueous humor (AH) or vitreous fluids (VF): 151 samples at admission and 133 after one intravitreal injection of antibiotics. Microbiological techniques include bacterial culture after inoculation into pediatric blood culture bottle, 16S PCR, real-time PCR assays for the detection of specific sequence regions of S. aureus femA gene and S. pneumoniae lytA gene. Quantitative real-time PCR assay targeting the tuf gene of Staphylococcus spp was used for 25 patients infected with S. epidermidis. Results: At the time of admission; the detection rate was not significantly different between PCR and cultures (38% versus 30% in AH samples; 66% versus 63% in vitreous fluid, p=0.6). ln contrast, after one intravitreous injection of antibiotics, the identification rate was higher using PCR (62%) in VF than using culture (48%, p=0.05). Bacteria was identified in 70% with a predominance of Gram-positive bacteria (93%). Specific PCR targeting S. aureus and S. pneumonia were notable to make additional diagnosis. Quantitative PCR performed before and after treatment found no significant changes in bacterial load after one intravitreal injection (51803 ±47161 DNA copies/ml at admission versus 95737 ±147431 after antibiotic treatment, p=0.6). Conclusion: Identification rate was better in vitreous fluid than in aqueous humor. 16s PCR is more effective than cultures in detecting bacteria in vitreous samples after intravitreal administration of antibiotics. PCR targeting S. aureus and S. pneumonia were specific but, with the low frequency of endophthalmitis due to these virulent bacteria, sensitivity was not determined. Real-time quantitative PCR targeting the tuf gene of Staphylococcus spp showed high level of bacterial load and no change of DNA copies after one intravitreal injection of antibiotics
Diagnostic bactériologique précoce des endophtalmies aiguës post-opératoires par spectrométrie de masse MALDI-TOF by Adriane Mailhac( )

1 edition published in 2016 in French and held by 2 WorldCat member libraries worldwide

L'endophtalmie aiguë post-opératoire est une complication infectieuse bactérienne sévère. Les principaux facteurs pronostiques sont la virulence de la bactérie en cause, la rapidité du diagnostic, et l'instauration d'un traitement adapté. Le diagnostic microbiologique est basé sur la détection des bactéries dans les prélèvements intraoculaires, par culture ou PCR. La spectrométrie de masse (SM) MALDI-TOF est actuellement utilisée pour l'identification rapide des bactéries isolées en culture, et est en cours de validation pour l'identification directe sur fluide biologique. L'objectif de mon travail était de développer un protocole de diagnostic bactériologique rapide des endophtalmies par SM. Nous avons d'abord évalué la possibilité d'analyser par SM des vitrés infectés in vitro (inoculum de 0,5 et O,125 McFarland (McF)) déposés sur cible classique ou nanoporeuse. Nous n'avons pas observé de différence significative entre les 2 cibles avec la banque de données Bruker Daltonics (p=0,8 pour 0,5 McF; p=0,7 pour 0,125 McF) ou la banque spécifique de support (p=0,12 pour 0,5 McF et p=0,23 pour 0,125 McF). Nous avons ensuite opté pour l'ensemencement des vitrés infectés en flacons d'hémocultures. Un protocole d'extraction long ou court était appliqué au surnageant des hémocultures positives avant analyse par SM. Ce protocole obtenait un taux d'identification satisfaisant (72% protocole court SDS, 83% protocole court eau, 92% protocole long SDS, 96% pour le protocole long eau), meilleure avec une extraction longue (p<0.0001). Ce travail a permis de développer un protocole de diagnostic rapide des endophtalmies par SM, permettant de réduire le délai diagnostique de 24H
Étude des modifications de la pression intraoculaire et des anomalies de la périmétrie automatisée chez les patients porteurs d'un syndrome d'apnées du sommeil présentant une néuropathie optique chronique après équipement par pression positive continue by Maryam Azarian-Valanejad( )

1 edition published in 2004 in French and held by 2 WorldCat member libraries worldwide

Notre étude détermine les effets de la pression positive continue sur l'évolution des neuropathies optiques glaucomateuse présentées par des patients porteurs d'un syndrome d'apnées du sommeil sévère. 4 de nos patients d'âge moyen de 52,4 ans présentaient un glaucome primitif à angle ouvert et 2 un glaucome à pression normal. 4 étaient porteurs d'un syndrome d'apnées du sommeil sévère dont les 2 présentant un glaucome à pression normal, le cinquième présentait un type modéré. Un seul de nos patient n'a pas observé son traitement par pression positive continue et une aggravation de la périmétrie automatisée a été notée mais les 4 autres qui avaient bien observé leur traitement ont présentaient une nette amélioration de leur champ visuel voire une stabilisation. Ces améliorations sont sujets à discussion : la suppression de l'hypoxémie nocturne, la normalisation de l'activité sympathique, la correction du dysfonctionnement endothélial ou encore la normalisation de la pression intra-oculaire suffisent-elles à expliquer cette évolution
Antithrombotics prevalence in a vitreoretinal surgery cohort of patients by Mathilde Gallice( )

1 edition published in 2014 in French and held by 2 WorldCat member libraries worldwide

La gestion périopératoire des patients traités par antithrombotiques lors d'une chirurgie vitréo-rétinienne ne répond à aucun consensus. En effet, le risque hémorragique et ses conséquences sur le pronostic fonctionnel lors de la poursuite du traitement antithrombotique est sujet de controverse. Par ailleurs, aucune donnée n'existe quant à la prévalence des nouveaux antithrombotiques dans cette population. Nous avons donc évalué la prévalence des traitements antithrombotiques dans une cohorte prospective issue de trois centres chirurgicaux. Parmi les 1313 patients, recrutés de février 2012 à novembre 2013, 235 étaient traités par au moins un antiagrégant plaquettaire et 87 étaient traités par au moins un anticoagulant. 3 patients étaient traités par prasugrel, 9 l'étaient par un nouvel anticoagulant oral (6 par rivaroxaban, 3 par pradaxa) et 1 par fondaparinux. D'après la littérature, les complications hémorragiques sont présentes dans 3% des cas lorsque le traitement antiagrégant plaquettaire est poursuivi et dans 10% des cas lorsque le traitement anticoagulant est poursuivi. Ainsi, le nombre de sujets nécessaires pour mettre en évidence une réduction de 50% de l'incidence cumulée des évènements hémorragiques parmi les patients recevant un traitement antiagrégant plaquettaire est de 12 270 par groupe (poursuite/arrêt du traitement) et de 1 239 patients par groupe (poursuite/arrêt du traitement) pour les anticoagulants. Ces résultats montrent la difficulté de constituer un essai comparatif randomisé contrôlé qui apporterait une conclusion à fort niveau de preuve
Étude de la prévalence des neuropathies optiques chez les patients atteints d'un syndrome d'apnées du sommeil modéré et sévère by Bénédicte Charlier-Blavier( )

Scene and human face recognition in the central vision of patients with glaucoma by Floriane Rutgé( )

1 edition published in 2018 in English and held by 1 WorldCat member library worldwide

Le Glaucome Primitif à Angle Ouvert (GPAO) affecte principalement la vision périphérique. Plusieurs études supportent l'idée que des déficits visuels peuvent exister dans des zones du champ visuel considérées comme normales en périmétrie automatisée. Nous avons étudié la perception de scènes et de visages dans le champ visuel central de patients atteints de GPAO. Les patients atteints de GPAO ont été classés en deux groupes selon l'analyse de leur périmétrie statique automatisée (Humphrey SITA standard 24-2) : 11 avec atteinte du champ visuel central, 11 sans atteinte centrale. 25 sujets sains appariés en âge ont participé. Tous les participants réalisaient deux tâches : des photographies de scènes et de visages humains étaient présentées dans les 6 degrés centraux de leur champ visuel. La tâche de détection estimait les fonctions visuelles de bas niveau, la tâche de catégorisation testait les capacités visuelles de reconnaissance, de plus haut niveau. Les patients avec atteinte du champ visuel central montraient un déficit en détection et catégorisation par rapport aux contrôles, pour toutes les images. Les patients sans atteinte du champ visuel central avaient des performances similaires aux contrôles pour la détection et la catégorisation des visages. Mais alors que la détection des scènes était similaire aux contrôles, ces patients montraient un déficit dans leur catégorisation. Ceci suggère qu'un déficit en vision périphérique pourrait être préjudiciable à la vision centrale. Cette étude révèle des déficits subtils dans le champ visuel central des patients atteints de GPAO, non prédictibles par la périmétrie statique automatisée de Humphrey SITA standard 24-2
