Summary
Urban living increases myopia incidence but slows progression. Implementing myopia control in less urbanized areas is crucial to address these findings.
Area of Science:
- Ophthalmology
- Public Health
- Epidemiology
Background:
- Global myopia prevalence is rising, particularly in urban settings.
- Understanding the impact of urbanization on myopia is critical for public health strategies.
Purpose of the Study:
- To investigate the association between urbanization and myopia.
- To analyze the relationship between urban living and myopia prevalence, incidence, progression, and severity.
Main Methods:
- A 2-year cohort study of 177,894 students in Tianjin, China.
- Quantified urbanization using satellite data and an urban score.
- Conducted 3 vision examinations over the study period.
Main Results:
- Urbanization positively correlated with myopia incidence (OR, 1.09-1.53) and prevalence (OR, 1.62).
- Increased urbanization was associated with decreased myopia progression (OR, 0.84-0.73) and severity.
- Significant associations were found between urban score and myopia outcomes (P < .02).
Conclusions:
- Urban living environments show a dual association with myopia: increasing incidence while slowing progression.
- Findings highlight the need for targeted myopia control strategies, especially in developing urban areas.
- Urgent implementation of myopia control is recommended in regions with increasing urbanization.

01:22Photoreceptors and Visual Pathways
6.0K
At the molecular level, visual signals trigger transformations in photopigment molecules, resulting in changes in the photoreceptor cell's membrane potential. The photon's energy level is denoted by its wavelength, with each specific wavelength of visible light associated with a distinct color. The spectral range of visible light, classified as electromagnetic radiation, spans from 380 to 720 nm. Electromagnetic radiation wavelengths exceeding 720 nm fall under the infrared category,...

01:16Focusing of Light in the Eye
2.8K
Light rays enter the eye through the cornea, a transparent dome-shaped tissue that is the eye's outermost layer. The cornea bends or refracts, light rays traveling to the pupil. The shape of the cornea determines how much of the light is bent and whether the image will be focused correctly on the retina at the back of the eye. Once the light has passed through both refraction layers, it converges into a single focal point onto a small area. This is where photoreceptors start transforming...

01:25Glaucoma: Overview
584
Glaucoma is an eye condition characterized by increased intraocular pressure that damages the retina and optic nerve, leading to irreversible blindness if left untreated. The human eye has various components, including the cornea, iris, pupil, lens, and optic nerve. Aqueous humor is secreted by the epithelium of the ciliary body in the posterior chamber and flows through the trabecular meshwork and canal of Schlemm, maintaining normal intraocular pressure. The trabecular meshwork and the canal...

01:27Open Angle Glaucoma: Treatment
455
In open-angle glaucoma, the iridocorneal angle remains open, but the trabecular meshwork becomes stiff, slowing down the outflow of aqueous humor. This causes a buildup of aqueous humor in the anterior chamber, leading to a sudden increase in intraocular pressure. The treatment for open-angle glaucoma focuses on reducing the elevated intraocular pressure by either decreasing the secretion of aqueous humor or increasing its outflow.

1.6K
Optical perception, or vision, is an extraordinary sense dependent on converting light signals received via the ocular organs. These organs, known as eyes, are securely positioned within the bony cavities of the skull, called orbits. The orbits serve a dual purpose: a protective shield for the ocular globes and a stable attachment point for the soft ocular tissues. The eye's external protective mechanisms include the eyelids, which are edged with lashes that act as a barrier against foreign...

01:15Depth Perception and Spatial Vision
668
Depth perception is the ability to perceive objects three-dimensionally. It relies on two types of cues: binocular and monocular. Binocular cues depend on the combination of images from both eyes and how the eyes work together. Since the eyes are in slightly different positions, each eye captures a slightly different image. This disparity between images, known as binocular disparity, helps the brain interpret depth. When the brain compares these images, it determines the distance to an object.
