Understanding Paediatric Ophthalmology: Treatments and Insights

When it comes to children's health, vision is often overlooked. However, good eyesight is crucial for a child's development and learning. Paediatric ophthalmology focuses on diagnosing and treating eye conditions in children. This field is essential for ensuring that kids can see well and thrive in their daily lives. In this blog post, we will explore the various treatments available in paediatric ophthalmology and provide insights into common eye conditions that affect children.

What is Paediatric Ophthalmology?

Paediatric ophthalmology is a specialized branch of medicine that deals with eye disorders in children. Unlike adults, children's eyes are still developing, which means that certain conditions can have different implications. Paediatric ophthalmologists are trained to handle these unique challenges. They not only treat eye diseases but also work to ensure that children's vision develops properly.

Importance of Regular Eye Exams

Regular eye exams are vital for children's eye health. Many eye conditions do not show obvious symptoms, making it essential to have routine check-ups. The American Academy of Pediatrics recommends that children have their first eye exam at six months, another one at three years, and then before entering school.

Signs Your Child May Need an Eye Exam

Parents should be aware of signs that may indicate a vision problem. These include:

• Squinting or tilting the head to see better.

• Frequent eye rubbing or tearing.

• Complaints of headaches or difficulty reading.

Common Eye Conditions in Children

Understanding the common eye conditions that affect children is crucial for early detection and treatment. Here are some of the most prevalent issues:

1. Vision and glasses

Vision is how much a child sees. For the first 12years of life, a child’s visual system is still developing. Detecting early the need for glasses is important for the normal development of a child’s vision.

During your child’s examination, an Orthoptist will first assess how much your child sees and how well both eyes work together.

Following this, Mrs Tsimpida will determine if your child needs glasses through a detailed eye exam. This exam usually involves eye drops to dilate the pupils and relax the focusing muscles of the eyes, in order to obtain the most accurate measurements.

2. Amblyopia (Lazy Eye)

Amblyopia, often referred to as lazy eye, occurs when one or both eyes do not develop proper vision. This condition can lead to permanent vision loss if not treated early. Spotting amblyopia can be tricky as children rarely complain about blurry vision.For this reason it is important that your child's eyes are checked by a Paediatric Ophthalmologist so that this condition, if present, is caught early and treated in a timely manner to obtain the best visual outcome.

Treatment options include:

• Glasses: The correct prescription can help the development of good visual function and the reversal of amblyopia.

• Eye Patches: For some children glasses alone may not be enough to help the amblyopia. In these cases a patch in front of the stronger eye can improve the vision in the weaker eye, by forcing the brain to use the weaker eye more.

• Atropine Drops for occlusion: These drops are instilled in the stronger eye twice a week and blur the vision in the stronger eye, promoting use of the weaker eye.

During amblyopia treatment, engage your child to his/her favorite activities, like playing board games, colouring,tablet time or hand-held computer games, to enhance the child's compliance to the treatment and achieve better visual outcomes.

3. Strabismus (Squint)

Strabismus is a condition where the eyes do not align properly. While one eye looks straight, the other eye may turn inwards (esotropia), outwards (exotropia), upwards (hypertropia) or downwards (hypotropia). This misalignment can be intermittent or constant.

The presence of a squint can affect the normal visual development. For this reason, if you suspect that your child has a squint, it will be advisable to book a paediatric eye specialist consultation for the timely diagnosis and management of the condition.

Symptoms of a squint:

a. Misalignment of eye

b.Double vision

c. Head tilting or face turning

d.Eye straining and headaches

e.Poor vision

f. Poor 3D vision

Diagnosis of a squint:

Your child will have a detailed orthoptic assessment of visual function, ocular alignment and eye movements. Following this, your child will have a refractive assessment and a detailed ocular health assessment by Mrs Tsimpida.

Treatment of squint:

Treatment options may include:

a. Glasses

b. Amblyopia treatment

c. Eye exercises

d. Surgery to strengthen or weaken certain eye muscles that are located on the surface of the eyes.

4. Headaches:

It is quite common for school children to complain of headaches. The excessive use of phone devices and tablets nowadays has increased the incidence of headaches among school children.

If your child is complaining of troublesome headaches that affect their everyday activities, it is advisable to book a paediatric eye assessment. This will include an assessment of visual function, ocular alignment, refractive status (need for glasses) and ocular health assessment, with a focus to exclude pathology like optic nerve swelling that will necessitate further diagnostic tests in the presence of headaches.

5. Myopia:

Myopia or shortsightedness is a condition where the vision is blurred for distance viewing.

Following the pandemic, a significant increase in the incidence of myopia in children has been reported, mainly due to the prolonged time children spend on digital screens and their excessive use.

Factors contributing to the progression of myopia include: 

·      Genetics (having one or both parents with myopia)

·      Prolonged near work (reading or screen time)

·      Insufficient outdoor activity

 In today's digital age, children are exposed to screens more than ever. While technology can be beneficial, excessive screen time can lead to eye strain and discomfort. Here are some tips to promote healthy screen habits:

• Follow the 20-20-20 rule: Encourage your child to take a break every 20 minutes. They should look at something 20 feet away for at least 20 seconds. This helps reduce eye strain.

• Limit screen time: Set boundaries on how much time your child spends on devices. The American Academy of Pediatrics recommends no more than one hour of screen time per day for children aged 2 to 5 years and no more than 2 hours per day for 6-17 years of age.

  
  

• Create a comfortable viewing environment: Ensure that the room is well-lit and that the screen is at eye level. This can help reduce strain on the eyes. Also, keep a forearm distance between the eyes and the books or screens.

Treatment options for myopia:

·      Glasses

·      Contact lenses (from teenage years)

·      There are currently new treatment modalities available on private prescription that have been shown to slow down myopia progression in children. These include specially designed glasses and contact lenses that change the focus in the peripheral vision (MiYOSMART /Stellest and MiSight respectively) as well as eye drops (low concentration atropine eye drops used daily).

Regular eye exams are important for monitoring myopia progression and adjusting treatment modalities, especially for children with a family history of high myopia.

The Emotional Aspect of Eye Conditions

Dealing with eye conditions can be challenging for children and their families. It is essential to address the emotional impact of these conditions. Here are some ways to support children:

1. Open Communication

Encourage children to express their feelings about their vision problems. Open discussions can help them feel understood and supported.

2. Support Groups

Connecting with other families facing similar challenges can provide comfort and advice. Support groups can be a valuable resource for both children and parents.

Tips for Parents

As a parent, you play a crucial role in your child's eye health. Here are some tips to keep in mind:

• Encourage Outdoor Play: Studies suggest that spending time outdoors can reduce the risk of developing myopia.

  
  

• Limit Screen Time: Too much screen time can strain the eyes. Encourage breaks and outdoor activities.

  
  

• Promote Healthy Eating: A balanced diet rich in vitamins A, C, and E can support eye health.
