Eye health occupies an important place in the developmental processes of children. As vision is a fundamental sense for learning and perceiving the environment, early diagnosis of eye diseases that arise during childhood allows for the prevention of permanent damage. Symptoms of vision problems in children can often appear as blinking, constant eye rubbing, headaches, and reading difficulties. When symptoms are noticed, a specialist doctor should be consulted.
What Are the Common Eye Diseases in Children?
The most common eye diseases in children include:
-
Strabismus
Strabismus, a frequent phenomenon in children, arises from the eyes not being properly aligned. Strabismus can be congenital or develop due to accidents or illnesses. It can be difficult for parents to diagnose mild cases of strabismus. This condition is usually detected within the first 3 months after birth and diagnosed through an eye examination.
-
Amblyopia (Lazy Eye)
Amblyopia is a condition that emerges due to a mismatch between the eye and the brain. Children with this disorder experience poor vision and may not express it accurately to their families.
A child's eyes and brain form important connections from birth up to age 8. Factors obstructing vision can affect these connections, and the brain may struggle to recognize images from the eye. In this case, the eye weakens, and amblyopia can develop.
-
Refractive Errors
Refractive errors include visual impairments such as hyperopia, myopia, and astigmatism. These types of defects can generally be easily managed with the use of glasses.
Astigmatism is a common vision issue—an error in refraction caused by problems in the focus of light rays into the eye. It alters the way light enters the eye, leading to blurred vision for objects both near and far. It typically stems from a distortion in the shape of the cornea.
Myopia, usually commencing between ages 6 and 14, affects about 5% of preschool children and approximately 9% of school-age children. If one of the parents is myopic, the chances of it appearing in the child are high. Myopia results from the length of the eyeball or the steepness of the cornea, hindering clear vision due to the rays falling below the retina.
-
Diplopia (Double Vision)
Double vision, also known as diplopia, means seeing two images instead of one. This condition can result in duplicated or overlapping images, leading to significant visual discomfort. In children and adolescents, strabismus is the most common cause of this concern for parents.
-
Nystagmus (Eye Trembling)
Nystagmus, also known as eye trembling, describes an uncontrolled, continuous movement of the eyes. While sometimes associated with other eye problems, it can also be seen in healthy children. Children are typically unaware of this condition, but others may notice the eye movements. Nystagmus can be congenital or result from illness and injury.
How Is Diagnosis Made in Child Eye Health?
Regular doctor visits are essential for protecting children's eye health. The doctor identifies vision issues and determines the appropriate treatment. During the diagnosis process, the following methods are used:
Red Reflex Test
The red reflex test, frequently applied during newborn examinations, allows for a detailed inspection of the baby's eyes with the help of a light. When light is shone into the baby's eyes, the reflection is expected to be red; a white reflection might indicate eye issues.
Visual Object Test
The object test for a newborn is carried out to determine if the baby can focus on visual objects. An interesting object is used to attract the baby's attention, and it is then observed whether the baby follows it with their eyes.
Pupil Reflex Test
Light is shone into both eyes of the baby to check the reaction of the pupils. The baby's pupils naturally tend to constrict in response to light; if this response is absent, there might be an issue.
Color Blindness Test
The color blindness test can be used to measure children's ability to recognize colors. Charts with patterns of colored dots are particularly preferred.
Strabismus Test
The strabismus test is used to determine the alignment of the eyes and whether their movements are synchronized.
When Should Eye Examinations Be Conducted by Age?
Monitoring child eye health should be done regularly according to developmental periods, not only when a complaint arises. Eye diseases can progress without symptoms, and the chance for treatment may be delayed.
-
0–1 Year: First Eye Check
Eye health examinations between the first 6 months and 1 year after birth can help diagnose and treat various eye diseases early. Structural anomalies like congenital cataracts can be detected during this period. Additionally, other eye problems like glaucoma can be identified and intervened with at an early stage.
Premature infants should be specially monitored for retinopathy given its higher risk in these babies. Conditions like lazy eye and eye movement disorders can also be identified and corrected early on. Therefore, babies' eye health should be routinely checked.
During the examination, the reaction of the eyes to light, pupil reflexes, and general eye structure are examined in detail. If there is a family history of eye problems, a more detailed retinal examination is recommended. These examinations allow for early detection of potential issues, enabling necessary precautions to be taken, ensuring the child grows healthily.
-
Age 3: Monitoring of Eye Muscles and Visual Acuity
Age 3 is when vision functions begin to fully develop, helping you learn about your child's eye health.
During check-ups, eye problems such as refractive errors (myopia, hyperopia, astigmatism) can be easily measured. If diagnosed early, the treatment process can be more effective and enhance your child's visual comfort. Disorders like strabismus, drifting, or double vision can also be detected through eye muscle tests during these check-ups. Early intervention can prevent these types of issues from progressing and make treatment easier.
Visual abilities are generally assessed using illustrated cards or symbols, and the alignment and tracking movements of the eyes are inspected to ensure both eyes are working in harmony.
-
Age 6 and Above: School Age Check-ups Should Be Regular
It is recommended that preschool children undergo an eye examination. Subsequently, routine check-ups should be conducted annually. Vision impairments can directly affect a child's academic success. Especially in children who use glasses, prescription changes and frame fit should be regularly monitored.
The time children spend in front of screens is also increasing. This can cause eye strain and focus problems.
More Frequent Check-ups May Be Necessary for Special Conditions
-
If there are genetic eye diseases in the family
-
If there is a history of premature birth
-
If there is neurological developmental delay or systemic diseases
-
If a prior diagnosed eye disease exists
In these cases, more frequent examinations may be required according to the schedule recommended by your doctor.
Treatment Methods Applied in Children's Eye Diseases
Treatment options vary according to the diagnosis:
-
Use of glasses: Effectively applied for refractive errors.
-
Occlusion therapy: Frequently applied in lazy eye. The healthy eye is covered to make the lazy eye work harder.
-
Orthoptic exercises: Special exercises aimed at strengthening the eye muscles.
-
Surgical intervention: Might be necessary for structural problems like strabismus.
The treatment process is personalized according to the child's age and the severity of the issue.
Suggestions for Parents to Protect Vision Health in Children
There are some important points that families need to pay attention to in daily life to prevent eye diseases. These points are important for protecting eye health and detecting potential problems early.
First of all, screen time should be limited. Children aged 0-6 should use digital screens in a limited and controlled manner.
It is important to ensure that children have contact with natural light. Outdoor play is beneficial for general health as well as supporting vision development and strengthening eye muscles. The Vitamin D found in sunlight is also highly beneficial for eye health.
Paying attention to nutrition habits is also a factor that positively affects eye health. Consuming foods containing nutrients such as Omega-3 fatty acids, Vitamin A, and lutein contributes to eye health. Foods like carrots, salmon, and spinach are rich sources in this regard.
Parents should also be aware of behavioral signs that may be seen in children. Frequent blinking, headaches, or attention issues can signal vision problems. Noticing these symptoms in time and consulting a specialist can prevent serious issues from arising later.
