Summary
Peripheral refraction in Japanese children showed a hyperopic shift, similar to other East Asian populations. This study found no link between myopia severity, axial length, and the degree of peripheral hyperopic shift.
Area of Science:
- Ophthalmology
- Pediatric Optometry
- Refractive Error Research
Background:
- Peripheral refraction plays a role in myopia progression.
- Understanding peripheral refractive profiles in diverse pediatric populations is crucial.
Purpose of the Study:
- To characterize peripheral refraction in Japanese children with mild to moderate myopia.
- To compare these findings with international data.
Main Methods:
- Cross-sectional study of 76 Japanese children (ages 6-12) with myopia.
- Cycloplegic refraction measured using an open-field autorefractor with eccentric targets.
- Analysis of spherical equivalent (M), J180, and J45.
Main Results:
- A significant hyperopic shift in M was observed in the peripheral retina.
- At ±30 degrees eccentricity, mean relative M was +1.16 D (nasal) and +1.64 D (temporal).
- No correlation found between peripheral M shift and on-axis refraction, axial length, or age.
Conclusions:
- Peripheral refraction profile in Japanese children resembles that of other East Asian populations.
- No evidence supports a link between myopia severity/axial length and the peripheral hyperopic shift in this cohort.

01:16Focusing of Light in the Eye
3.4K
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...

01:28Angle Closure Glaucoma: Treatment
885
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...

01:27Open Angle Glaucoma: Treatment
746
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.

01:26Influence of Earth's Curvature and Atmospheric Refraction on Leveling
338
During leveling, the Earth's curvature and atmospheric refraction introduce deviations in the line of sight from a true horizontal reference. When the line of sight is leveled, it remains perpendicular to the plumb line only at a single point. Beyond this, it deviates due to the Earth’s curvature, represented by the correction C. For a sight distance D, the deviation can be derived using the relationship:This relationship shows that the deviation increases quadratically with distance.
