Efficacy and safety assessment of azithromycin 1.5% eye drops (azyter) in peri-operative antibio-prophylaxis for cataract surgery
2009
International audience; Introduction: Background: Endophthalmitis is still one of the most fearsome complications of cataract surgery. The most important pathogens causing post-operative phacoemulsification endophthalmitis are staphylococci. Methods: 85 patients were included in a phase II pilot study. Patients were divided in three groups, group 1 and 3 received either azithromycin 1.5% eye drops or placebo eye drops one day before surgery and for 2 days after surgery and group 2 received azithromycin 1.5% eye drops for 3 days after surgery. Treatments were administered twice a day: one drop in the morning and one in the evening. Bacterial samples were collected three times from the conjun…
Neurophysiologic Testing in Infants With Usher Syndrome Type 1
2009
Purpose: Usher syndrome type 1 needs to be diagnosed at early age, when speech therapy and cochlear implantation can stimulate communication in a deaf child who will confront an additional visual handicap. Molecular diagnosis is not routinely available. Visual function tests are not easily performed in young children. Before the age of six years, progressive retinal degeneration does not always show fundoscopic changes and few data are available regarding neurophysiologic abnormalities. This study was designed to describe electroretinogram (ERG) and visual evoked potentials (VEP) in a series of fourteen children with Usher syndrome type I.Methods: Monocular ERG and binocular VEP were perfor…
Acute Postcataract Surgery Endophthalmitis Due to Streptococcus Species Differs From Endophthalmitis Due to Staphylococcus Species at Presentation
2009
Purpose: : To correlate the presenting clinical ophthalmic features with the bacterial identification in 100 patients with acute post catarcat endophthalmitis enrolled in the FRench Instutionnal ENdophthalmitis Study (FRIENDS).Methods: : Demographic data, past medical history and initial eye examination were recorded in a standardized form in 100 patients with acute endophthalmitis after cataract extraction (< 6 weeks) in a prospective multicenter study. Relationship between microbiological identification (using conventional cultures and panbacterial PCR) and clinical factors at baseline was studied using univariate (ANOVA).Results: : 100 patients were hospitalized for endophthalmitis treat…
Impact of a reduction of plasmalogen levels on Muller cell metabolism
2016
Purpose : Retinopathy of Prematurity (ROP) is the leading cause of blindness in premature children resulting from abnormal vascular development. Previous studies have shown that omega-3 polyunsaturated fatty acids (PUFAs) can modulate physiologic and pathologic angiogenesis. Data from our laboratory suggest that plasmalogens, that are phospholipids that concentrate omega-3 PUFAs, are involved in the regulation of post-natal retinal vascular development through the action of a calcium-independent phospholipase A2 (iPLA2) (Saab et al PLoSONE 2014). In the retina, Müller cells are known to play crucial functions in retinal angiogenesis as well as to be rich in plasmalogens and to express phosp…
Functional and anatomical outcomes after successful macula-off retinal detachment surgery, a 12 month-follow-up
2016
This is an abstract that was submitted for the 2016 ARVO Annual Meeting, held in Seattle, Wash., May 1-5, 2016.; Purpose: To describe the changes of retinal structure and function after successful repair of macula-off rhegmatogenous retinal detachment (RRD). Methods: Prospective multicenter study including patients with successful surgery for macula-off RRD between October 2011 and April 2014. Those with pre-existing macular diseases or with surgery failures were excluded. Each patient underwent a complete ophthalmologic exam at baseline and at 1, 3, 6 and 12 months after the surgery (M1, M3, M6, M12, respectively). Function was assessed by measuring the best-corrected visual acuity (BCVA) …
Factors of good visual outcome in acute post-cataract endophthalmitis (friends group)
2009
International audience; Purpose: To analyze initial clinical factors of good visual outcome in patients with acute endophthalmitis following cataract surgery. Methods: A prospective study was performed in 4 University hospital (Dijon, Grenoble, Lyon, Saint-Etienne, FRIENDS group) on 100 patients with acute post-cataract endophthalmitis. Factors related to cataract surgery (complications), the initial presentation and the microbiological identification were analyzed according to the final visual outcome using univariate and multivariate analysis (SPSS 12.0). Results: 46% out of the patients had a final visual acuity less than or equal to 0.3 logMar (good visual outcome) at 6 months while 10%…

Plasma omega 3 polyunsaturated fatty acids and macular pigment optical density in subjects at high risk for age-related macular degeneration: the Lim…
2016
This is an abstract that was submitted for the 2016 ARVO Annual Meeting, held in Seattle, Wash., May 1-5, 2016.; Purpose: In numerous epidemiological studies, omega 3 polyunsaturated fatty acids (PUFAs) have been associated with a decreased risk of age-related macular degeneration (AMD). Beyond their structural, functional and neuroprotective roles, omega 3 PUFAs may favor the retinal accumulation of lutein and zeaxanthin and thus increase macular pigment optical density (MPOD). We examined the associations of MPOD with plasma omega 3 PUFAs in subjects with at least one parent affected by neovascular AMD. Methods: The Limpia study is a double-blind, placebo controlled, prospective randomize…
Maternal odor selectively enhances the categorization of face(like) stimuli in the 4 month-old infant brain
2020
Présentation Poster; International audience; In the 4-month-old infant brain, the visual categorization of natural face images is enhanced by concomitant maternal odor (Leleu et al., 2019), providing support for the early perception of congruent associations between co-occurring inputs from multiple senses. Here, we further explore whether this maternal odor effect is selective to faces or if it can be explained by a more general influence of salient odor cues on the perception of any visual object category. In Experiment 1, scalp electroencephalogram was recorded during a fast periodic visual stimulation (FPVS-EEG) while 4-month-old infants were exposed to the maternal vs. a control odor. …
