---|---|---|---|---|
Primary | Refractive status | Cycloplegic spherical refraction measured by auto-refractometer (Diopter) in children and adolescents. | 1 day | |
Secondary | Axial length | The axial length is the distance between the anterior surface of the cornea and the fovea and is the primary determinant of non-syndromic myopia. In this research project, investigators measure the axial length in children and adolescents by A-scan. | 1 day | |
Secondary | Intraocular pressure | Intraocular pressure is the pressure created by the continual renewal of fluids within the eye. In this research project, investigators measure the intraocular pressure in children and adolescents by Icare Tonometer. | 1 day | |
Secondary | Corneal thickness | Corneal thickness is an important factor in accurately diagnosing eye pressure. In this report project, investigators measure the corneal thickness in children and adolescents by A-scan. | 1 day | |
Secondary | Fundus examination | The fundus is the portion of the inner eye that can be seen during an eye examination by looking through the pupil. In this research project, investigators perform the fundus examination in children and adolescents by ophthalmoscope. | 1 day | |
Secondary | Serious and non-Serious Adverse Events | The adverse events in children and adolescents | 1 day | |
Secondary | Questionnaire | Associated factors such as families, genetics, school environment, living environment and behaviors | 1 day |
