2023年3月7日 · Axial myopia. Axial myopia results from the eyeball being too long relative to the eye's focusing power. It is the most common type of childhood myopia. Myopia in children is usually due to axial myopia. The axial length of the eyeball is the distance from the cornea to …

2022年11月24日 · If the axial length goes beyond 24mm, the point at which light is focused within the eye may move in front of the retina. As a result, it becomes harder to see objects clearly at a distance. This is known as myopia or short-sightedness, specifically axial myopia.

2022年3月9日 · The most common form of nearsightedness is called axial myopia. It occurs when the distance from the cornea to the back of the eye (the axial length) is too long relative to the focusing power of the cornea and lens. As a result, light focuses in …

There are two main types of myopia, refractive myopia and axial myopia. Understanding how the eye works can make it easier to understand what exactly myopia is. A sensitive and intricate organ, the eye is designed to help us see and interpret the world clearly.

2024年4月13日 · What is Axial Length in Relation to Myopia? Axial length is the measure from the front (cornea) to the back (retina) of the eye, indicating the depth of the eye’s globe. This measurement is crucial in eye health, particularly in understanding and managing myopia, or nearsightedness.

2022年5月21日 · Axial myopia is the most common type observed in clinical practice and is caused by an increase in the axial length of the globe. A 1-mm increase in the axial length correlates with a myopic shift of 3 D, also known as spherical myopia.

The axial length of the eye is a measured from front-to-back, and it grows too long in myopia; Normal axial eye growth occurs in childhood until around age 12, but in myopia it grows too quickly and continues until the late teens; A key goal of myopia control is to keep axial length below 26mm if possible, to protect long term eye health.

2023年2月28日 · It refers to the fact that myopic patients can see well at near, but have poor distance vision.¹ Myopia occurs if the refractive surfaces (for example, the front surface called the cornea) of the eye are too curved and/or if the distance from the front to the back of the eye (axial length) grows too long.

Axial length (AL) is the primary determinant of non-syndromic myopia. It is a parameter representing the combination of anterior chamber depth, lens thickness and vitreous chamber depth of the eye. AL can also be treated as an endophenotype of myopia and may provide extra advantages in the investigation of its genetic basis.

Myopia occurs when the shape of your eye causes light rays to refract (bend) incorrectly, focusing images in front of your retina instead of on your retina. It occurs because the eye is too long (axial myopia), or has a cornea (the clear front surface of your eye that passes light to …
