[Thésaurus HELB]:Optique:port de lentilles de contactMots-clés : kératite microbienne Résumé : SIGNIFICANCE: Think Tank 2019 affirmed that the rate of infection associated with contact lenses has not changed
in several decades. Also, there is a trend toward more serious infections associated with Acanthamoeba and fungi.
The growing use of contact lenses in children demands our attention with surveillance and case-control studies.
PURPOSE: The American Academy of Optometry (AAO) gathered researchers and key opinion leaders from around
the world to discuss contact lens–associated microbial keratitis at the 2019 AAO Annual Meeting.
METHODS: Experts presented within four sessions. Session 1 covered the epidemiology of microbial keratitis,
pathogenesis of Pseudomonas aeruginosa, and the role of lens care systems and storage cases in corneal disease.
Session 2 covered nonbacterial forms of keratitis in contact lens wearers. Session 3 covered future needs, challenges, and research questions in relation to microbial keratitis in youth and myopia control, microbiome, antimicrobial surfaces, and genetic susceptibility. Session 4 covered compliance and communication imperatives.
RESULTS: The absolute rate of microbial keratitis has remained very consistent for three decades despite new
technologies, and extended wear significantly increases the risk. Improved oxygen delivery afforded by silicone hydrogel lenses has not impacted the rates, and although the introduction of daily disposable lenses has minimized
the risk of severe disease, there is no consistent evidence that they have altered the overall rate of microbial keratitis. Overnight orthokeratology lenses may increase the risk of microbial keratitis, especially secondary to
Acanthamoeba, in children. Compliance remains a concern and a significant risk factor for disease. New insights
into host microbiome and genetic susceptibility may uncover new theories. More studies such as case-control designs suited for rare diseases and registries are needed.
CONCLUSIONS: The first annual AAO Think Tank acknowledged that the risk of microbial keratitis has not decreased over decades, despite innovation. Important questions and research directions remain.Permalink : https://bibliotheque.helb-prigogine.be/opac_css/index.php?lvl=notice_display&id= [article]Exemplaires

[Thésaurus Mesh]Solutions pour lentilles cornéennesRésumé : SIGNIFICANCE: A multipurpose disinfecting solution (MPDS), which contains povidone-iodine (PI) as a disinfectant, has high disinfecting efficacy not only on planktonic bacterium but also on the case biofilms. The addition of case hygiene practice removed more bacteria from cases than MPDS alone. PURPOSE: This study compared the ability of two MPDSs, one containing PI and another containing polyaminopropyl biguanide and polyquaternium, to reduce bacterial numbers in solution or adhered to the cases following case hygiene procedures. METHODS: Bacterial strains (Delftia acidovorans, Pseudomonas aeruginosa, Stenotrophomonas maltophilia, Serratia marcescens, Staphylococcus aureus, and Staphylococcus epidermidis) were exposed to the MPDSs for the recommended disinfection times, and the viable number evaluated according to ISO 14729. Cases were inoculated with bacterial strains and incubated for 24 hours to allow for biofilm formation. Cases were disinfected with both disinfecting solutions for 4 hours and rinsed, followed by recapping or air-drying, or tissue-wiping and air-drying for 18 hours. The number of survivors was counted using standard culture techniques. RESULTS: Both products exceeded the recommended 3-log reduction against planktonic bacteria. Regarding biofilm, after rinsing and recapping wet, the numbers of D. acidovorans (mean difference [95% confidence interval] log10 colony-forming units per case, −2.9 [0.8 to −4.6], P < .01), P. aeruginosa (−2.0 [0.5 to −3.1], P < .01), S. marcescens (−1.7 [0.8 to −3.5], P < .05), and S. epidermidis (−2.1 [0.6 to −3.5], P < .05) in PI cases were significantly lower than in the dual-disinfectant MPDS storage cases. After air-drying, the PI storage cases had significantly lower numbers of S. maltophilia (−2.6 [0.6 to −4.0], P < .01), D. acidovorans (−1.6 [0.7 to −3.3], P < .05), and S. aureus (−1.6 [0.7 to −3.1], P < .05). The addition of tissue-wiping reduced the bacterial numbers in the MPDS storage cases to levels in the PI storage cases. CONCLUSIONS: Contact lens users should be recommended to tissue-wipe and air-dry their lens storage cases after disinfection with regular MPDS.
