[Thésaurus Mesh]Tissu conjonctifRésumé : SIGNIFICANCE: Scleral lenses (SLs) are increasing in scope, and understanding their ocular health impact is imperative. The unique fit of an SL raises concern that the landing zone causes compression of conjunctival tissue
that can lead to resistance of aqueous humor outflow and increased intraocular pressure (IOP).
PURPOSE: This study aimed to assess changes in optic nerve head morphology as an indirect assessment of IOP
and evaluate other IOP assessment methods during SL wear.
METHODS: Twenty-six healthy adults wore SL on one randomly selected eye for 6 hours, whereas the fellow eye
served as a control. Global minimum rim width (optical coherence tomography) and IOP (Icare, Diaton) were measured at baseline, 2 and 6 hours after SL application, and again after SL removal. Central corneal thickness, anterior chamber depth, and fluid reservoir depth were monitored.
RESULTS: Minimum rim width thinning was observed in the test (−8 μm; 95% confidence interval [CI], −11 to
−6 μm) and control (−6 μm; 95% CI, −9 to −3 μm) eyes after 6 hours of SL wear (P < .01), although the magnitude
of thinning was not significantly greater in the lens-wearing eyes (P = .09). Mean IOP (Icare) significantly increased
+2 mmHg (95% CI, +1 to +3 mmHg) in the test eyes (P = .002), with no change in the control eyes. Mean IOP
changes with Diaton were +0.3 mmHg (95% CI, −0.9 to +3.2 mmHg) in the test eyes and +0.4 mmHg (95%
CI, −0.8 to +1.7 mmHg) in the control eyes. However, Diaton tonometry showed poor within-subject variation
and poor correlation with Icare. No clinically significant changes were observed in central corneal thickness or anterior chamber depth.
CONCLUSIONS: This study suggests that SLs have a minimal effect on IOP homeostasis in the normal eye during
SL wear and an insignificant impact on the optic nerve head morphology in healthy adult eyes.Permalink : https://bibliotheque.helb-prigogine.be/opac_css/index.php?lvl=notice_display&id= [article]Exemplaires

Children are being fitted at younger ages with soft contact lenses for myopia control. This 3-year investigation of adverse events related to contact lens wear in 7- to 11-year-old participants helps optometrists understand what to expect when fitting children with soft contact lenses.
PURPOSE
The purpose of this article is to report the frequency and type of ocular and nonocular adverse events related to soft contact lens wear in children.
METHODS
Seven- to 11-year-old children wore soft contact lenses for 3 years. Adverse events were defined by a slit-lamp examination finding of grade 3 or worse; parental report of a clinically meaningful change (determined by the examiner) in eyes, vision, or health; or a clinically meaningful response (determined by examiner) to a symptom checklist. Adverse events were categorized and reported by examiners and finalized by the Executive Committee. The presence or absence of an infiltrate and a list of diagnoses was determined at the conclusion of the study.
RESULTS
The 294 participants wore their contact lenses 73.0 ± 26.5 hours per week, and 220 (74.8%) encountered at least 1 adverse event. Of the 432 adverse events, 75.2% were ocular, and 24.8% were nonocular. Contact lens wear was probably or definitely related to 60.6% of the ocular and 2.8% of the nonocular adverse events. None of the ocular adverse events were serious or severe or caused permanent contact lens discontinuation. The corneal infiltrate incidence was 185 cases per 10,000 patient-years of wear (95% confidence interval, 110 to 294). The incidence of moderate ocular adverse events that were definitely or probably related to contact lens wear was 405 cases per 10,000 patient-years of wear (95% confidence interval, 286 to 557).
CONCLUSIONS
The adverse events experienced by 7- to 11–year-old myopic children rarely required meaningful treatment and never led to permanent discontinuation of contact lens wear or loss of best-corrected vision.Permalink : https://bibliotheque.helb-prigogine.be/opac_css/index.php?lvl=notice_display&id= [article]Exemplaires
