Biometry in Myopia

The Importance of Biometry in Myopia Management

Biometry in Myopia

Myopia, also known as nearsightedness, is a common eye condition that makes distant objects appear blurry while close objects can be seen clearly. This issue is becoming more widespread, especially among children and young adults. With the growing use of digital devices and less time spent outdoors, myopia rates are soaring in Canada. Managing myopia effectively is crucial to prevent it from getting worse and to avoid serious eye problems later in life, like retinal detachment or glaucoma.

One of the most important tools in myopia management is the measurement of axial length, which is the length of the eye from front to back. This measurement is done using a technique called biometry. Understanding and tracking axial length can help eye doctors create better treatment plans to control myopia progression.

In this blog post, you will learn about:

  • The growing issue of myopia and why it’s important to manage it early.
  • How axial length measurement works and why it’s a key factor in myopia management.
  • Practical insights on how these tools can be used to create effective myopia control strategies.

Let’s get started!

Understanding Myopia

Myopia, commonly known as nearsightedness, is a condition where distant objects appear blurry while close objects can be seen clearly. There are different types of myopia, each with unique characteristics:

  • Simple Myopia: This is the most common form, usually developing in childhood and stabilizing in adulthood. It typically results from the eye being too long or the cornea being too curved.
  • Pathological Myopia: Also known as degenerative or high myopia, this type progresses rapidly and can lead to severe vision problems. It is often inherited and can cause significant changes in the structure of the eye.

Causes and Risk Factors

Several factors contribute to the development of myopia:

  • Genetics: If one or both parents are nearsighted, there is a higher chance their children will be too.
  • Environmental Factors: Spending less time outdoors and more time on close-up tasks, like reading or using digital devices, can increase the risk of developing myopia.
  • Lifestyle: Modern lifestyles that involve extensive screen time and limited outdoor activities contribute significantly to rising myopia rates.

Implications of Untreated Myopia

If myopia is not managed properly, it can lead to severe eye health issues:

  • Progressive Vision Loss: Myopia can worsen over time, leading to increasingly poor vision.
  • Retinal Detachment: High myopia can stretch and thin the retina, making it more prone to detachment.
  • Glaucoma and Cataracts: People with high myopia have a greater risk of developing glaucoma and cataracts, which can further impair vision.

The Science of Axial Length Measurement

Axial length is the distance from the front to the back of the eye, encompassing structures like the cornea, lens, and retina. It is a critical measurement in eye health, especially in the context of myopia. Longer axial lengths are often associated with higher degrees of myopia. Monitoring this length helps eye doctors track the progression of myopia and assess the risk of related complications.

How Axial Length is Measured Through Biometry

Biometry is a technique used to measure the axial length of the eye with high precision. It involves the use of specialized devices to capture detailed images and data about the eye’s structure.

Different Methods of Biometry

  • Optical Coherence Biometry (OCB): This method uses light waves to create detailed cross-sectional images of the eye. It is non-invasive and highly accurate.

  • Ultrasound Biometry: This traditional method uses sound waves to measure axial length. It involves placing a small probe on the eye’s surface or in the tear film, which can be slightly uncomfortable but effective.

Advantages of Using Optical Coherence Biometry

Optical coherence biometry offers several benefits over traditional methods like ultrasound:

  • Non-invasive and Comfortable: Since OCB uses light instead of sound waves, there is no need for direct contact with the eye, making the process more comfortable for patients.

  • High Precision: OCB provides extremely accurate measurements, which are crucial for effective myopia management and other eye health assessments.

  • Speed and Efficiency: The procedure is quick, typically taking just a few seconds, which is convenient for both patients and clinicians.

  • Detailed Imaging: OCB can produce detailed images of the eye’s internal structures, aiding in the diagnosis and monitoring of various eye conditions.

How Axial Length Correlates with Myopia Progression

Axial Length in myopia

Axial length is directly linked to the degree of myopia. As the eye elongates, the axial length increases, causing the light entering the eye to focus in front of the retina instead of directly on it. This elongation is a key indicator of myopia progression. By measuring and monitoring axial length, eye doctors in Toronto can assess how quickly myopia is worsening and adjust treatment plans accordingly.

Regular monitoring of axial length is especially important for children and adolescents, as their eyes are still growing and myopia can progress rapidly during these years. Early detection of changes in axial length allows for timely interventions, which can slow down or even halt the progression of myopia. This proactive approach can prevent severe myopia and reduce the risk of future eye health complications.

Myopia Management Strategies Involving Biometry

Overview of Myopia Management Strategies

  • Orthokeratology (Ortho-K): This involves wearing specially designed rigid contact lenses overnight, which temporarily reshape the cornea. During the day, the patient can see clearly without glasses or contact lenses.
  • Atropine Drops: Low-dose atropine eye drops are used to slow the progression of myopia in children. The drops are typically applied daily.
  • Specialized Lenses: These include multifocal contact lenses or spectacle lenses designed to reduce the progression of myopia by altering the focus of light entering the eye.

Benefits of Combining Axial Length Measurements with Other Diagnostic Tools

A comprehensive approach to myopia management involves using multiple diagnostic tools alongside axial length measurements:

  • Refraction Tests: Measure how light bends as it enters the eye, helping to determine the correct prescription for glasses or contact lenses.
  • Corneal Topography: Maps the surface curvature of the cornea, essential for fitting contact lenses and assessing the effects of orthokeratology.
  • Fundus Photography: Captures detailed images of the retina, aiding in the detection of changes or complications related to high myopia.

Axial length measurements give insight into the structural changes associated with myopia, while other diagnostic tools help in understanding functional aspects and potential complications. This integrated approach enables eye doctors to develop more effective, personalized treatment plans, ensuring better long-term outcomes for individuals with myopia.

Children’s Eye Health: A Parent’s Guide to Healthy Vision

children's eye health

Have you ever wondered why your child squints at the TV or holds books close while reading? These could be signs of an underlying vision problem. Just like strong legs help a child run and play, healthy eyes are essential for a child’s development. From having a good time at the playground to excelling in school, clear sight is important. This guide will be your roadmap to understanding your child’s eye health, packed with tips to ensure they see the world with vibrant clarity.

Why Are Eye Exams Important for Children?

eye exam in children

While your child might not complain about blurry vision, scheduling regular eye exams is just as important as those annual checkups at the pediatrician. Here’s why:

1. Early Detection, Early Treatment

Children often don’t realize they have vision problems, especially if they’ve never experienced clear sight. Eye exams can detect issues early on when treatment is most effective. This is crucial for conditions like amblyopia (lazy eye), where early intervention can prevent permanent vision loss.

2. Unveiling Hidden Issues

Even if your child seems to see perfectly, eye exams can uncover underlying problems that might affect their development. Squinting, headaches, and difficulty focusing can be signs of nearsightedness, farsightedness, or astigmatism – all conditions easily addressed with glasses or contacts.

3. Healthy Eyes, Healthy Development

Good vision is a cornerstone of a child’s learning and development. It allows them to participate fully in school activities, read comfortably, and engage in sports and hobbies. Undiagnosed vision problems can lead to frustration, difficulty concentrating, and even behavioral issues. 

Now, let’s look at some specific vision problems commonly detected during eye exams:

  • Lazy Eye (Amblyopia): This occurs when one eye weakens due to lack of use. Early detection and treatment, often involving patching the stronger eye, can strengthen the weaker one and prevent permanent vision loss.
  • Nearsightedness (Myopia): Nearsighted children see close objects clearly, but struggle with distant ones. Glasses or contacts can correct this, allowing them to see the board clearly in school.
  • Farsightedness (Hyperopia): Farsighted children see distant objects well, but struggle with close-up tasks like reading. Glasses can help them focus on near objects.
  • Astigmatism: This is a common condition where the cornea is irregularly shaped, causing blurred vision at all distances. Glasses or contacts can correct this astigmatism and provide clear vision.

By scheduling regular eye exams with a pediatric optometrist in Toronto, you’re giving your child the gift of clear sight, setting them up for a lifetime of success in learning, playing, and exploring the world around them.

Recognizing Signs of Vision Problems in Children

Regular eye exams are crucial, but you can also play a vital role in detecting potential vision problems in your child between appointments. Here’s how to be your child’s very own eye detective:

  • Squinting or Straining to See: This is a classic sign that your child might be having trouble focusing. Watch for squinting at the TV, or computer screen, or when trying to read books held close.
  • Frequent Headaches: Headaches, especially after reading or focusing on close work, can be a sign of eyestrain. 
  • Difficulty Reading or Focusing: Does your child struggle to keep their place while reading, lose interest quickly, or complain about blurry text? These could indicate vision problems.
  • Closing One Eye to See Better: This might suggest your child favors one eye over the other, a potential sign of lazy eye (amblyopia).
  • Poor Hand-Eye Coordination: Clumsiness when catching a ball or difficulty with activities requiring hand-eye coordination could be linked to vision problems. 

These signs don’t necessarily guarantee a vision problem, but they warrant a conversation with your child’s pediatrician or a visit to an optometrist. Early detection and intervention are key to ensuring your child thrives with healthy vision.

Fostering Healthy Vision Habits in Children

Solar Eclipse 2024 – Once-in-a-lifetime event for Beaches and the Rosedale-Yorkville Area

On April 8, 2024, a rare celestial phenomenon is set to occur, which hasn’t been witnessed in North America for almost a decade. It’s the total solar eclipse, and it’s expected to be an awe-inspiring event that will captivate millions of people across the continent. But for folks in two specific locations, namely Beaches and the Rosedale-Yorkville area, this natural wonder will be an especially unforgettable experience. This rare celestial event is one not to be missed. In this blog post, we’ll explore what a solar eclipse is, where the path of totality will fall, and how you can safely observe this extraordinary event!

What is a Solar Eclipse?

A solar eclipse occurs when the moon passes between the sun and the Earth, blocking the sun’s light and casting a shadow on parts of the Earth. There are three types of solar eclipses – total, partial, and annular – depending on the alignment of the moon, sun, and Earth. During a total solar eclipse, the moon completely blocks the sun, creating a rare and spectacular sight in the sky. The last total solar eclipse visible in North America was in 2017, and the next one is set to occur on April 8, 2024. It’s a once-in-a-lifetime event that will be especially memorable for those in the path of totality, including Beaches and the Rosedale-Yorkville area.

Solar Eclipse

Path of totality versus partial eclipse

During a solar eclipse, the path of totality refers to the area on Earth where the moon will completely block the sun, creating a total solar eclipse. This relatively narrow path can vary in size and shape depending on the location of the eclipse. For the solar eclipse occurring on April 8, the path of totality will stretch from Mexico through the United States and up to Canada.

Outside of the path of totality, observers will experience a partial solar eclipse, where the moon only partially blocks the sun’s light and creates a crescent-shaped shadow. While still an impressive sight, a partial eclipse doesn’t compare to the awe-inspiring experience of a total solar eclipse. 

From start to finish, the eclipse will be visible for about 2 hours, with totality lasting 2-3 minutes. Click here to get a more detailed map.


How to View Solar Eclipse 2024 Safely

Ultraviolet Radiation

Ultraviolet Radiation and Your Eyes

Ultraviolet Radiation

Who doesn’t enjoy a day of fun under the sun? While we’re aware of the skin damage excessive sun exposure can cause, it’s important to note that its ultraviolet (UV) rays can also harm our eyes.  Many people are aware of the risks of skin cancer caused by excessive exposure to ultraviolet (UV) light. As a result, they apply sunscreen to their skin before going outside. However, protecting our eyes from UV light is just as important. 

Studies have shown that over one-third of adults have experienced symptoms from prolonged UV exposure, such as eye irritation, impaired vision, and red or swollen eyes. The good news is that protecting your eyes is just as easy as protecting your skin. This blog post provides some tips to keep in mind.

What is UV

The sun emits various types of UV rays, with UVA and UVB being particularly concerning as they are not fully absorbed or altered by the atmosphere. This means they can pose a risk to both eyes and skin. The level of risk depends on several factors, including geographic location, altitude, and time of day. UV levels are higher in tropical areas near the equator and increase at higher altitudes. UV levels are typically higher from 10 a.m. to 2 p.m.

Other factors that affect the risk of UV exposure include your surroundings and the medications you take. For example, environments with highly reflective surfaces like sand and snow can result in higher UV exposure compared to urban areas with many tall buildings providing shade. Surprisingly, seasonal changes have less impact than expected. Despite feeling the sun more in summer, winter can be twice as dangerous due to the high reflectivity of snow.

Why Are Eyes at Risk?

UV radiation, originating from the sun, has a harmful impact on eye health. Exposure to UV rays can lead to various eye problems, including cataracts, macular degeneration, pingueculae, pterygia, photokeratitis, and eye and skin cancers.

  • Cataracts: The World Health Organization (WHO) estimates that up to 20 percent of cataract cases are preventable and can be attributed to UV radiation.
  • Macular Degeneration: Age-related macular degeneration (AMD), a leading cause of blindness in adults aged 60 and older, has been significantly associated with early AMD due to higher UV exposure at a younger age.
  • Pingueculae and Pterygia: These visible growths on the eye’s surface can lead to corneal issues and vision distortion.
  • Photokeratitis: Also known as snow blindness, photokeratitis is like a sunburn on the cornea, causing temporary vision loss and significant discomfort.
  • Cancer: The Skin Cancer Foundation reports that a tenth of all skin cancers are found on the eyelid. Exposure to UV radiation, especially UVB, is a primary cause of eyelid tumours. Additionally, nearly 3,000 intraocular cancer cases are diagnosed annually in the U.S.

Many people are unaware of how much damage their eyes sustain during their younger years. UV exposure accumulates over a lifetime, making it impossible to reverse skin or eye damage that has already occurred. However, you can reduce the risk of further damage. If you’re young or have young children, take advantage of this knowledge and increase sun protection to mitigate future risks.

How to Stay Safe?


It’s important to protect your eyes from harmful UV rays, just like you protect your skin with sunscreen. Sunglasses are a great way to do this, but not all sunglasses are created equal. Some may not provide adequate protection, so it’s important to check the labels or examine them with  optometrists in Beaches Toronto or Rosedale Toronto. Ensuring that your shades block 100 percent of UV rays is crucial.

Contrary to popular belief, the color of your sunglass lenses has little impact on UV protection. Whether they’re amber, grey, or brown matters less than the built-in UV protection each lens offers.

When it comes to frame style, close-fitting and wraparound styles offer better protection as they block more rays from entering through the sides of the frames. Additionally, wearing a wide-brimmed hat can provide an extra layer of protection.

It’s important to remember that you should protect your eyes even on overcast days. Reflected UV rays can be harmful all year round. In summer, rays reflected from buildings, sand, and lakes can pose a hazard. Similarly, in winter, reflected UV rays can also be harmful.


In conclusion, protecting our eyes from UV radiation is just as important as protecting our skin. UV rays can cause various eye problems, including cataracts, macular degeneration, pingueculae, pterygia, photokeratitis, and eye and skin cancers. To reduce the risk of damage, it’s important to wear sunglasses that block 100% of UV rays, choose close-fitting or wraparound styles, and wear a wide-brimmed hat.  By taking these simple steps, we can protect our eyes and prevent long-term damage.


Q: Are there any long-term effects of UV radiation on the eyes?

Long-term exposure to UV radiation can contribute to the development of cataracts and age-related macular degeneration (AMD), which can lead to vision loss. Protecting your eyes from UV radiation can help reduce these risks.

Q: Can I get enough UV protection from tinted or polarized lenses?

Tinted and polarized lenses may reduce glare and improve visual comfort, but they do not necessarily provide UV protection. For adequate protection, look for sunglasses specifically designed to block UV rays.

Q: How can I tell if my sunglasses offer adequate UV protection?

Look for sunglasses that are labeled as providing “100% UV protection” or “UV400.” Additionally, consider purchasing sunglasses from a reputable retailer to ensure their authenticity.
