Why Myopia Increases the Risk of Retinal Detachment

From the desk of Dr. Shi

Imagine waking up one morning and seeing flashes of light or dark shadows floating in your vision. While that may sound like something out of a movie, it’s often a real and serious warning sign of retinal detachment, one of the most serious complications of high myopia.

Retinal detachment is a serious condition that can lead to permanent vision loss if not treated quickly. At Honest Eye Doctor, we help patients across East Round Rock, Round Rock - Central, Georgetown, and South Austin take preventive steps to protect their vision—starting with early myopia management.

What is High Myopia?

Myopia, or nearsightedness, is a common vision condition where distant objects appear blurry while close-up vision stays clear. It occurs when the eye is longer than normal or the cornea is curved more steeply, causing light to focus in front of the retina instead of directly on it.

People with myopia will often get a prescription based on how severe their nearsightedness is. This prescription is measured in diopters, which reflect how strong their glasses or contact lenses need to be.

High myopia means someone has a prescription of -6.00 diopters or more, which requires much stronger lenses to help them see clearly at a distance. At this level, the risk of eye problems like retinal detachment, cataracts, and glaucoma goes up a lot.

What is Retinal Detachment

Retinal detachment is a serious eye condition that occurs when the retina—the thin, light-sensitive layer at the back of your eye—pulls away from the tissue that supports it. When this happens, the retina can no longer send clear signals to the brain, leading to partial or complete vision loss if not treated quickly.

Retinal detachment can happen suddenly. Getting care quickly can help save your vision. Watch for these warning signs:

• Sudden floaters (specks or cobwebs in your vision)
• Flashes of light in one or both eyes
• A shadow or curtain moving across your field of vision
• Blurry or distorted vision

How Retinal Detachment Happens

This condition often begins with small tears or holes in the retina. Fluid can then pass through these openings and build up underneath the retina, separating it from the eye wall. The longer the retina stays detached, the greater the risk of permanent vision damage.

Other risk factors for myopia retinal detachment include:

• Aging
• Eye injuries
• Previous eye surgery
• Family history of retinal problems

Why Retinal Detachment is More Common with High Myopia

So, how common is retinal detachment in high myopia?

According to the National Institutes of Health (NIH), people with high myopia are much more likely to develop retinal detachment than those with lower prescriptions. The retina becomes thinner and more prone to damage. This can cause small tears or holes in the retina. If fluid gets behind these openings, it can push the retina away from the back of the eye—a condition known as retinal detachment.

How to Prevent Retinal Detachment in High Myopia

The good news? Retinal detachment isn’t inevitable. You can significantly reduce your risk with the right steps and regular care. Here are some of the top treatment options to help you prevent retinal detachment:

Regular Comprehensive Eye Exams

Comprehensive eye exams are one of the best ways to catch changes early, especially in those with high prescriptions. We use advanced imaging tools to monitor the retina closely. If we notice thinning or small tears, we can take action before a detachment happens.

Orthokeratology (Ortho-K)

These special custom-fitted contact lenses are worn overnight to reshape the cornea gently. This can reduce the need for daytime glasses or contacts—and more importantly, it can slow how quickly a child’s myopia worsens. Slower eye growth means less stretching of the retina over time.

Slowing down eye elongation means less strain on the retina over time, which can lower the risk of retinal detachment later in life. ortho-k is especially helpful for active children or those not yet ready for refractive surgery in the future.

Scleral Lenses

For patients with myopia, scleral lenses are a great option. These large, gas-permeable lenses rest on the white of the eye and help correct vision clearly and comfortably. While they don’t slow myopia progression, they offer relief and stability for people with advanced prescriptions or corneal irregularities.

Screen Time & Outdoor Habits

Spending more time outdoors and reducing screen time can help slow myopia in children. At Honest Eye Doctor, we work closely with families to encourage small but impactful changes to protect long-term eye health.

Treatment Options for Retinal Detachment

If retinal detachment starts, immediate high myopia retinal detachment treatment is crucial. Depending on the severity and location of the detachment, treatment may involve:

• Laser Surgery: Seals retinal tears before detachment occurs
• Cryopexy (Freezing Treatment): Repairs small retinal breaks
• Pneumatic Retinopexy: A gas bubble is injected to help reattach the retina
• Scleral Buckling: A silicone band is placed around the eye to relieve the pulling
• Vitrectomy: Removal of the vitreous gel and repair of the detached retina

Outcomes are often better when the condition is caught early, but some vision loss can be permanent depending on how long the retina was detached.
