Assessing the Impact of Streetscape Exposure on Children's Perception

2026年8月5日 更新者：Zhongshan Ophthalmic Center, Sun Yat-sen University
The primary objective is to determine how streetscape exposure influences children's visual perception and psychological perception. The secondary aim is to identify streetscape elements associated with both visual and psychological perception, thereby providing evidence for environmental interventions in urban planning and public health.

Children aged 6 to 18 suffer from myopia or emmetropia

描述

Inclusion Criteria:

- 1: Myopia group: (1) informed consent obtained; (2) children aged 6-18 years; (3) no contraindications for wearing the eye-tracker (e.g., high astigmatism, head/neck injury); (4) myopia already present in at least one eye (spherical equivalent ≤ -0.50 D).

2: Emmetropia group: (1) informed consent obtained; (2) children aged 6-18 years; (3) no contraindications for wearing the eye-tracker (e.g., high astigmatism, head/neck injury).

Exclusion Criteria:

- 1: Myopia group: (1) high myopia in either eye (spherical equivalent ≤ -6.00 D); (2) any ocular pathology other than myopia (strabismus, amblyopia, congenital cataract, juvenile glaucoma, retinal disease, etc.); (3) systemic disorders that may affect vision or visual development (e.g., diabetes); (4) anisometropia > 1.00 D or astigmatism > 2.00 D in either eye.

2: Emmetropia group: (1) myopia or hyperopia in either eye (spherical equivalent ≤ -0.50 D or ≥ +0.50 D); (2) any ocular pathology (strabismus, amblyopia, congenital cataract, juvenile glaucoma, retinal disease, etc.); (3) systemic disorders that may affect vision or visual development (e.g., diabetes); (4) anisometropia > 1.00 D or astigmatism > 2.00 D in either eye.

团体/队列
干预/治疗
Myopia group
(1) informed consent obtained; (2) children aged 6-18 years; (3) no contraindications for wearing the eye-tracker (e.g., high astigmatism, head/neck injury); (4) myopia already present in at least one eye (spherical equivalent ≤ -0.50 D).
其他：Virtual simulation of street visual environment exposure
Transforming real street scenes into virtual simulation environments, and recreating the visual exposure of actual street scenes in a laboratory setting through wearing VR headsets.
Emmetropia group
(1) informed consent obtained; (2) children aged 6-18 years; (3) no contraindications for wearing the eye-tracker (e.g., high astigmatism, head/neck injury).

研究衡量的是什么？

主要结果指标

结果测量
措施说明
大体时间
Environmental defocus
大体时间：First day
The eye movement behaviors of the subjects were measured using the HTC VR helmet and the 7XINiwei aSee Studio, and then calculated by combining with the deep learning algorithm.
First day

次要结果测量

结果测量
措施说明
大体时间
Perception evaluation
大体时间：First day
After the experiment process was completed, the Environmental Perception Questionnaire was used to measure the subjects' psychological perception of the streetscape environment, such as whether it was safe and comfortable. By comparing the pictures, the option that better matches the description is selected. The more times a picture is chosen, the safer or more comfortable it is considered.
First day

其他结果措施

结果测量
措施说明
大体时间
Intensity of physical activity
大体时间：First day
Use the modified GPAQ physical activity questionnaires. Each question has 5 options, representing scores from 0 to 5. The arithmetic mean score of all the questions represents the activity level of the child.
First day
Axis Length
大体时间：First day
Under natural pupils, axial length was measured with the IOL Master. One eye was occluded while the fellow eye fixated straight ahead; three readings were taken and averaged.
First day
Refractive demand at fixation
大体时间：First day
The eye movement behaviors of the subjects were measured using the HTC VR helmet and the 7XINiwei aSee Studio, and then calculated by combining with the deep learning algorithm.
First day
Visual acuity
大体时间：First day
Use the ETDRS visual acuity chart
First day
Non-cycloplegic refraction
大体时间：First day
Measure using an automatic optometry instrument. The refractive power measured in the non-ciliary muscle paralysis state is expressed by the equivalent spherical refraction (SER), where SER = spherical refractive power + 1/2 × cylindrical refractive power. Computer refraction operation standard: Each eye is measured continuously 3 times, and the average value automatically output by the instrument is taken as the final result.
