Summary
Higher-order ocular aberrations in myopia decrease and then increase with age, being lowest between 25-35 years. Astigmatism with the rule decreases, while against-the-rule astigmatism increases with age.
Area of Science:
- Ophthalmology
- Optometry
- Biomedical Engineering
Context:
- Age-related changes in ocular aberrations are crucial for understanding refractive error progression.
- Myopia and myopic astigmatism are common refractive errors influenced by various factors, including age.
- Wavefront aberrometry provides detailed analysis of lower- and higher-order aberrations.
Purpose:
- To investigate age-related trends in ocular aberrations using machine learning in a large cohort of myopic and myopic astigmatic patients.
- To identify age groups with minimum higher-order aberrations and analyze changes in astigmatism types with age.
Summary:
- This retrospective study analyzed wavefront data from 1,507 myopic and myopic astigmatic patients (ages 15-40).
- Higher-order aberrations generally decreased and then increased with age, with minimums observed between 25-35 years.
- Astigmatism with the rule decreased with age, while astigmatism against the rule and oblique astigmatism increased.
Impact:
- Provides insights into the natural progression of ocular aberrations throughout adulthood.
- Highlights the age group (25-35 years) with potentially optimal visual quality in terms of higher-order aberrations.
- Contributes to a better understanding of refractive error development and management strategies.

01:16Focusing of Light in the Eye
3.0K
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
584
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...
