What is Hypertropia?
Written by Medicover Team and Medically Reviewed by Dr Priyanka (Gaikwad) Bhat , Ophthalmologist
Hypertropia is an eye condition where one eye points up more than the other. It's a type of strabismus, which simply means the eyes don't line up in the same direction. Instead of moving together, one eye drifts upward. This can affect how clearly you see and how well your eyes work as a team.
It can happen to children or adults, and sometimes, the difference is small and hard to notice. At other times, it can be more obvious and impact daily activities. People with hypertropia may experience difficulty reading, playing sports, or walking without feeling unsteady.
Normally, six tiny muscles in each eye work together, so both eyes move as a team. With hypertropia, these muscles don't stay balanced, so one eye drifts upward.
This can make things look blurry or cause double vision (seeing two of the same thing). Some people feel their eyes get tired or strained from trying to focus. Children may not even realise there's an issue. They might tilt their head without noticing, just to see better.
Key points about hypertropia:
- One eye is turning up instead of staying level with the other
- It can be present from birth or develop later due to nerve problems or injury
- It may cause double vision or trouble focusing
- Children might tilt their heads to see better
- Early treatment can help prevent vision problems
If you or your child seems to have an eye that turns up or has trouble seeing clearly, it's a good idea to see an eye doctor. With the right care, many people with hypertropia can improve their vision and feel more comfortable in daily life.
What Are the Hypertropia Symptoms?
The primary symptom of Hypertropia is an eye that turns upward while the other remains straight. This misalignment can make it hard for both eyes to work together properly. It can happen in children or adults, and the signs might be easy to miss at first. Recognising the symptoms of hypertropia early is important so you can receive the right treatment and avoid long-term vision problems.
If you suspect hypertropia, you might notice:
- Double vision (seeing two of the same object)
- Eyes that don't move together
- Head tilting or turning to try to see clearly
- Difficulty focusing on objects or reading
- Eye strain or tired eyes after short periods of reading or watching TV
- Trouble with depth perception, making judging distances harder
- Closing one eye to see better or reduce double vision
- Frequent squinting or blinking to clear vision
In children, parents may see them tilting their heads a lot or struggling to follow objects. They may not always complain about seeing double, so watch for these subtle signs. If you notice any of these symptoms, it's a good idea to see an eye doctor.
What Are the Causes of Hypertropia?
Hypertropia happens when one eye turns upward compared to the other. It's a type of eye muscle problem (strabismus) that can make it hard for both eyes to work together. Let's look at why this can happen.
Causes of hypertropia include:
- Nerve problems: Sometimes the nerves controlling eye muscles don't work right, leading to imbalanced movement.
- Muscle weakness or tightness: An eye muscle may be too weak or too tight, pulling the eye up.
- Injuries: Head injuries can damage nerves or muscles that move the eyes.
- Eye surgery: Certain surgeries can change how the muscles work, causing one eye to drift upward.
- Stroke: In older adults, strokes can affect the nerves that move the eyes.
- Congenital causes: Some people are born with hypertropia because their eye muscles didn't develop evenly.
- Certain health conditions like Graves' disease, Thyroid eye disease, Brown syndrome, and Myasthenia gravis possibly cause hypertropia.
For children, hypertropia is often due to issues present at birth. In adults, it can develop from other health problems that affect nerves or muscles.
Who Does Hypertropia Affect?
Hypertropia can affect people of any age, from babies to older adults. It's important to know who might be at risk so you can catch it early.
Hypertropia can affect:
- Newborns and children: Some babies are born with hypertropia because of muscle or nerve issues. Parents may notice one eye always drifting upward.
- Adults with health conditions: Problems like diabetes or high blood pressure can damage nerves that move the eyes.
- Those with head injuries: Accidents or falls can injure the nerves or muscles that control eye movement.
- People who've had eye surgery: Some surgeries can change how eye muscles work, leading to alignment problems later on.
Hypertropia isn't caused by anything you did wrong. It's often due to how the eye nerves and muscles work together.

Diagnosing hypertropia is all about finding out why one eye is looking higher than the other. Your eye doctor will do a careful exam to see how your eyes move and work together. It's simple and doesn't hurt at all.
Here's what usually happens during the check-up:
- Eye movement tests: You'll follow a small light or object with your eyes to see how well they move.
- Cover test: The doctor covers one eye at a time to watch how the other eye adjusts.
- Visual acuity test: You'll read letters on a chart to check how clearly you see.
- Eye alignment check: Special tools help the doctor see how your eyes line up.
- Medical history review: They'll ask about any past eye problems or health conditions.
Sometimes, you need an MRI test if it's needed. These tests help the doctor find the cause and decide on the best treatment for you.
How Is Hypertropia Treated?
Hypertropia treatment completely depends on how it is caused. The treatment goal is to help the eyes work together properly and improve vision. Your eye doctor will suggest the best approach after a thorough exam.
Here's how hypertropia is typically managed:
- Glasses or Prescription Lenses: If hypertropia is due to farsightedness or other focusing issues, glasses can help align the eyes better. For some children, special lenses like prism lenses may reduce double vision.
- Eye Patching: Sometimes, doctors recommend covering the stronger eye for a few hours a day. This helps the weaker eye work harder, which can improve alignment over time. It's often used for children to strengthen the eye muscles.
- Eye Exercises: Simple Hypertropia eye exercises may help improve coordination between the eyes. These are often given by an eye specialist and done at home.
- Surgery: In cases where the misalignment is severe or doesn't improve with other treatments, surgery may be suggested. The doctor adjusts the eye muscles so the eyes point in the same direction. It's usually a quick procedure with good results.
- Managing Underlying Conditions: If a nerve problem or other health issue is causing hypertropia, treating that condition can help improve eye alignment.
When to See a Doctor for Hypertropia?
Hypertropia can sometimes be mild, but in other cases, it may signal an underlying issue that needs treatment. Seeing a doctor early can help prevent problems with vision and depth perception.
Consider seeing a doctor if you notice:
- One eye turning upward, even occasionally
- Double vision or blurry vision
- Trouble focusing on objects
- Head tilting to see better
- Frequent eye strain or headaches
- Difficulty reading or doing close-up tasks
- Changes in vision after an injury
If these signs are present, it's best to get an eye specialist's opinion. Early treatment can make a big difference, especially for children whose vision is still developing.

What Is the Recovery Process After Hypertropia Treatment?
Recovering from hypertropia treatment depends on the cause of the condition and the type of treatment used, such as glasses, eye exercises, or surgery. Most people start noticing improvements in their vision and eye alignment within a few weeks.
Here's what you can expect during recovery:
- Rest your eyes after any procedure or eye exercises. Avoid screen time for long periods.
- Follow your doctor's instructions for using glasses, patches, or medications.
- Attend all follow-up appointments so your doctor can track progress.
- If surgery was done, expect some redness or mild discomfort for a few days.
- Children may need additional therapy or patching if a lazy eye is involved.
With regular care and guidance from your eye doctor, most people recover well and regain better eye coordination. Always reach out if symptoms return or worsen.
How Can I Prevent Hypertropia?
Hypertropia caused by nerve or muscle issues may not always be preventable, but some steps can reduce risks, especially in children or people with vision problems.
Prevention Tips:
- Get regular eye check-ups, especially for children.
- Treat underlying eye issues like lazy eye (amblyopia) early.
- Wear corrective glasses if prescribed.
- Protect your eyes from injury, as trauma can trigger eye muscle problems.
- Manage health conditions like diabetes or thyroid issues that may affect eye nerves.
What Are the Possible Complications?
Possible Complications if Left Untreated:
- Double vision that affects daily activities
- Poor depth perception, making driving or reading harder
- Eye strain and headaches
- Delayed development in children, especially in reading and focus
- Permanent vision imbalance if not treated early
