Inuit myopia: an environmentally induced "epidemic"?
Canadian Medical Association Journal
|March 8, 1975
Summary
Myopia, or nearsightedness, is rapidly increasing among young Inuit, particularly females. Environmental and cultural factors, possibly including school attendance, are suspected causes, not genetics.
Area of Science:
- Ophthalmology
- Public Health
- Anthropology
Background:
- Myopia prevalence is significantly higher in young Inuit (<30 years) compared to older generations.
- This trend is particularly pronounced in Inuit females.
Purpose of the Study:
- To investigate the reasons behind the escalating myopia rates in young Inuit.
- To explore potential environmental and cultural factors contributing to this phenomenon.
Main Methods:
- Analysis of age and sex distribution of myopia prevalence.
- Review of existing data on Inuit lifestyle and education.
Main Results:
- A strong correlation between younger age, female sex, and high myopia prevalence was observed.
- Genetic factors appear to play a minimal role in this observed increase.
- Environmental and cultural influences are strongly implicated.
Conclusions:
- The current myopia epidemic among young Inuit is likely driven by environmental or cultural factors, not genetics.
- School attendance is a potential contributing factor requiring further investigation.

Overview
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...
01:27Open 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.

01:16Focusing 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...
01:22Photoreceptors 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...
01:22Microbiome of the Eye
The human eye has a specialized microbiota that reflects its unique anatomical and immunological environment. This low-biomass microbial community predominantly colonizes the conjunctiva and eyelid margins, playing a vital role in ocular surface homeostasis and defense. Despite its proximity to the richly colonized facial skin, the ocular surface maintains a distinct microbial profile due to continuous mechanical and biochemical defense mechanisms.The conjunctival surface hosts fewer microbial...
