Myopes have significantly higher serum melatonin concentrations than non-myopes.
PURPOSE Experimental animal models of myopia demonstrate that higher melatonin (Mel) and lower dopamine (DA) concentrations actively promote axial elongation. This study explored the association between myopia and serum concentrations of DA and Mel in humans. METHODS Morning serum concentrations of DA and Mel were measured by solid phase extraction-liquid chromatography-tandem mass spectromet...
متن کاملAccommodative lag under habitual seeing conditions: comparison between adult myopes and emmetropes.
PURPOSE To clarify whether myopes show poor accommodative response and thus have a larger accommodative lag under natural seeing conditions. METHODS Forty-three adults without other ocular abnormalities were classified into the early-onset myopia (EOM, n=28) and the emmetropia (EMM, n=15) groups. The subjects wore glasses or contact lenses that they habitually used, and accommodative response...
متن کاملAccuracy of WASCA aberrometer refraction compared to manifest refraction in Chinese adult myopes.
PURPOSE To investigate the accuracy of the Carl Zeiss Meditec Wavefront Supported Custom Ablation (WASCA) aberrometer in refraction testing for Chinese myopic adults. METHODS Manifest refraction and WASCA were performed on 360 eyes of 360 consecutive Chinese myopic adults without cycloplegia. Both vector analysis and conventional notation were applied for comparing results, and differences be...
متن کاملPhotoastigmatic Refractive Keratectomy in Myopes
Journal of Refractive Surgery Volume 16 March/April 2000 ABSTRACT PURPOSE: Photoastigmatic refractive keratectomy (PARK) was studied in a multi-center clinical trial. The Nidek EC-5000 excimer laser was evaluated for its effect on refraction, visual acuity, and safety measures as part of a U.S. Food and Drug Administration (FDA) regulated study. METHODS: Eight U.S. centers enrolled adults with ...
متن کاملIntraocular Pressure Changes during Accommodation in Progressing Myopes, Stable Myopes and Emmetropes
PURPOSE To investigate the changes of intraocular pressure (IOP) induced by 3-diopter (3 D) accommodation in progressing myopes, stable myopes and emmetropes. DESIGN Cross-sectional study. PARTICIPANTS 318 subjects including 270 myopes and 48 emmetropes. METHODS 195 progressing myopes, 75 stable myopes and 48 emmetropes participated in this study. All subjects had their IOP measured using...
