Abnormal changes in the morphology of corneal endothelium are indicators of corneal stress or instability which could be linked to myopia.\n                  <\/ns4:p>\n                  <ns4:p>\n                    <ns4:bold>Methods:<\/ns4:bold>\n                    111 school children comprising of 37 emmetropes, 37 mild myopes and 37 moderate myopes aged 8-9 years old were recruited. Visual acuity was measured using the LogMar chart, cycloplegic refraction was determined using an open-field autorefractor (Grand Seiko WAM-5100, Hiroshima, Japan) and refined using subjective refraction. Morphology of corneal endothelial cells [endothelial cell density, coefficient of variation, hexagonality and central corneal thickness] was evaluated using a non-contact specular microscope (Topcon SP-2000P). Axial length was measured with A-scan ultrasound biometry (PacScan Plus, Sonomed Escalon, NY). The correlation between morphology of corneal endothelial cells and axial length were assessed using Pearson Correlation and Linear regression analysis.\n                  <\/ns4:p>\n                  <ns4:p>\n                    <ns4:bold>Results:<\/ns4:bold>\n                    There was no significant difference in corneal endothelial cells and axial length between gender (p&gt;0.05). Significant reduction in endothelial cells density and hexagonality and increased coefficient of variation was found in eyes of higher myopic power which had longer axial when compared to emmetropes (p&lt;0.001). Except for central corneal thickness, all corneal endothelial cells parameters correlated significantly with axial length (p&lt;0.05). For every 1mm increase in axial length, endothelial cells density decreased by 73.27cells\/mm\n                    <ns4:sup>2<\/ns4:sup>\n                    , hexagonality decreased by 2.32% and coefficient of variation increased by 1.75%.\n                  <\/ns4:p>\n                  <ns4:p>\n                    <ns4:bold>Conclusions<\/ns4:bold>\n                    : There were significant changes in morphology of cornea endothelial cells in young moderate myopic children of Chinese ethnicity at 8-9 years of age.
