Juvenile myopia progression, risk factors and interventions
1The Wilmer Eye Institute, The Johns Hopkins University, Baltimore, MD, USA.
Summary
Early onset myopia is a public health concern. Increased outdoor time in children may reduce myopia risk, while genetic and environmental factors require further investigation for effective interventions.
Area of Science:
- Ophthalmology
- Public Health
- Genetics
Background:
- Myopia, or nearsightedness, is a significant public health issue with visual, quality of life, and economic consequences.
- Uncorrected refractive errors, primarily myopia, contribute substantially to global visual impairment.
- Understanding the etiology of myopia is crucial for developing effective prevention and management strategies.
Purpose of the Study:
- To investigate the contributing factors to early-onset myopia.
- To explore the roles of genetic and environmental influences on myopia development and progression.
- To review current and potential interventions for juvenile myopia.
Main Methods:
- Review of twin studies supporting genetic factors in myopia.
- Analysis of environmental factors including near work, education, location, and outdoor time.
- Examination of population studies gathering genetic and environmental cohort data.
Main Results:
- Genetic loci for myopia have been identified, but a comprehensive genetic model is lacking.
- Environmental factors like increased near work and urban living are associated with myopia.
- Children spending more time outdoors show a reduced likelihood of developing myopia.
Conclusions:
- Myopia is a complex disorder influenced by both genetic and environmental factors.
- Increased outdoor time is a promising factor in preventing juvenile myopia.
- Further research is needed to understand the interaction between genetic and environmental influences for targeted interventions.

01:27Open Angle Glaucoma: Treatment
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.

01:28Angle Closure Glaucoma: Treatment
Angle-closure glaucoma, or closed-angle glaucoma, is an eye condition where the iris bulges out and blocks the iridocorneal angle, resulting in a buildup of aqueous humor and increased intraocular pressure. Immediate medical attention is necessary due to the sudden onset of symptoms. The treatment for angle-closure glaucoma includes short-term and long-term approaches. Short-term treatment involves using eye drops like pilocarpine to lower intraocular pressure by increasing aqueous humor...
01:25Glaucoma: Overview
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...
01:22Photoreceptors and Visual Pathways
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, whereas...
01:16Focusing of Light in the Eye
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...
01:17Accessory Structures of the Eye
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...
