Is your child often asking “Have we arrived?”, “When do we arrive?”, complaining of headaches, abdominal pain or you need to be all the time equipped with plastic bags in case he vomits?

Then you are surely terrified at the thought about long-distance car vacation.

Motion sickness is very unpleasant, and when children are affected, the problem is even worse.

 

Why do we feel motion sickness?

Motion sickness, sometimes referred to as sea sickness or car sickness, is a very common disturbance of the inner ear that is caused by repeated motion. The symptoms of motion sickness arise from the inner ear (labyrinth) due to changes in a person’s sense of balance and equilibrium.

One gets motion sickness when one part of the balance-sensing system (the inner ear , eyes, and sensory nerves) senses that the body is moving, but the other parts don’t. For example, if you are in the cabin of a moving ship, your inner ear may sense the motion of waves, but your eyes don’t see any movement. This conflict between the senses causes motion sickness. Symptoms of motion sickness are: nausea, vomiting, headaches, dizziness, sweating, and a sense of feeling unwell.

In children, balance receptors are fully formed in the second year of life; at this time they can feel motion sickness just like adults.

Prompt acceleration and deceleration in a space where nothing moves from inside can cause motion sickness too.

 

Tips for avoiding motion sickness:

  • Watch your child’s consumption of foods and drinks before and during travel. Avoid excessive foods or liquids that “do not agree with him” or make him feel unusually full. Heavy, spicy, or fat-rich foods may worsen motion sickness in some people. Avoiding strong food odors may also help prevent nausea.
  • Place the child on the car seat or directly on the bench, if his age allows it, with the head as straight as possible. Such a posture is favourable for the stomach, but also for the eyes, which will be able to better focus on the view outside the car.
  • Teach the child to look to the things outside, instead of focusing on objects within a short distance of him (such as magazines, books or various gadgets). You can tell him to count the trees on the roadside or the cars running in the opposite direction.
  • Stop the car as many times as needed and let the little one to get outside and make a few steps. Even if this means you will arrive later, it is important to have a pleasant trip.
  • Travel at night, because in this period the balance receptors in the inner ear are less sensitive to external stimuli.

If, despite all the preventive measures tested, the child still has motion sickness at every journey, the problem can be solved by treatment.

 

How to treat/prevent motion sickness

Generally, medication for motion sickness ranges from different drugs to controversial “remedies” that, unfortunately, treat only the symptoms of motion sickness, not the cause.

Moreover, many drugs have side effects, which are extremely undesirable, especially in babies, young children or pregnant women.

Therefore, starting from the desire to treat the cause and not just the symptoms, a software was created. It comprises some exercises intended to balance the visual perception and movement sensors from the inner ear.

The exercises will allow the brain to synchronize the information received from the eye with those from the inner ear.

The software looks like a computer game, which makes it a child friendly and effective treatment method.

By means of these exercises, the conflicting signals transmitted to the brain by the two sense systems will be removed, and the motion sickness will disappear.

So, after a few game therapy sessions, you will notice that the symptoms of motion sickness will diminish in intensity and then completely disappear.

Whether you have experienced motion sickness or you have at least one family member who needs lots of pills or mint candies every time he needs to travel somewhere, you probably know that any trip or long journey is a real challenge for those who suffer from this health problem.

Motion sickness affects at least 25% of the population worldwide, children under the age of 12 being most sensitive.

 

Symptoms of motion sickness

Motion sickness, sometimes referred to as sea sickness or car sickness, is a very common disturbance. Symptoms of motion sickness are:

– nausea
– pale skin
– sweating
– vomiting
– dizziness
– migraine
– excessive salivation
– a sense of feeling unwell

In addition to sea travel, motion sickness can develop from the movement of a car or from turbulence in an airplane.
Anyone can develop motion sickness, but people vary in their sensitivity to motion. However, there are some people most commonly affected by motion sickness:

  • Children from 2 to 12 years old.
  • Women, especially those who are pregnant, on menstruation or receiving hormonal treatments. Men are much less affected.
  • People who are prone to migraines.
  • Individuals under a certain treatment: although not necessarily triggering motion sickens, some drugs tend to increase nausea associated with kinetosis.

 

Causes of motion sickness

Motion sickness, sometimes referred to as sea sickness or car sickness, is a very common disturbance of the inner ear that is caused by repeated motion. The symptoms of motion sickness arise from the inner ear (labyrinth) due to changes in a person’s sense of balance and equilibrium.

One may feel sick from the motion of cars, airplanes, trains, amusement park rides, or boats or ships, but also from video games, flight simulators, or looking through a microscope. In these cases, the eyes see motion, but the body doesn’t sense it.

One gets motion sickness when one part of the balance-sensing system (the inner ear , eyes, and sensory nerves) senses that the body is moving, but the other parts don’t. For example, if you are in the cabin of a moving ship, your inner ear may sense the motion of waves, but your eyes don’t see any movement. This conflict between the senses causes motion sickness.

Concomitantly, there are two other recurring things that further increase the chances of experiencing motion sickness:

 

– Anxiety (people who have already experienced motion sickness in the past may have their general condition worsen simply because they are stressed and expect to have motion sickness again)

– Long exposure (long exposure is also very important. However, for longer journeys, such as on sea, the brain and the body can adapt to the continuous movement, and nausea is no longer triggered.)

If motion sickness continues after the trip has ended, a general medical examination is mandatory. This is the only way to exclude other causes of kinetosis, such as a viral infection of the inner ear.

If not treated, symptoms may evolve to repeated vomiting, dehydration, and blood pressure fall. All of these may have serious consequences, which is why people with severe kinetosis should not hesitate to attend a doctor.

 

How to treat/prevent motion sickness

Generally, medication for motion sickness ranges from different drugs to controversial “remedies” that, unfortunately, treat only the symptoms of motion sickness, not the cause.

Moreover, many drugs have side effects, which are extremely undesirable, especially in babies, young children or pregnant women.

The Features of the Visual System in a Child

The normal functioning of the child’s visual system is an essential condition not only for the perception itself, but also for the development of all organs and systems. The eye is a sight organ, but also a “consumer” of light energy. Due to the stimulating action of the light, the endocrine glands (pituitary, adrenal, thyroid, gonads) synthesize hormones. Faster adaptation of the new-born to the environment, the growth and development of the child depends largely on the proper functioning of the visual system, which is why the visual analyser of the child is formed very quickly. The growth and development of the eye in a child ends mainly by the age of 2-3 years, in the next 15-20 years there are much less changes than in the first years.

  • New-born’s eyeAs a rule, the eye of a new-born and of a young child is with hypermetropia. As the eye grows, the refraction becomes normal. During the first 3 years of life the important increase of the eyeball occurs, as well as the flattening of the cornea and especially of the lens.
  • Cornea
  • In the first few months of life, due to the incomplete functional development of the cranial nerves, the cornea is not sensitive. This period is particularly dangerous, because when foreign bodies enter the eye, there is no eye irritation; the child does not experience pain and anxiety and serious damage could happen to the cornea, even until it is destroyed. Subsequently, the sensitivity of cornea increases and in a one-year-old child it is almost the same as in an adult.
  • Iris
  • The iris is the anterior part of the choroid and represents a vertical diaphragm with a hole in the middle – pupil – for adjusting the light influx into the eye, depending on external conditions. The colour of the iris may be different – from light blue to black, depending on the melanin content: the higher the amount of pigment, the darker is the iris. Children’s iris contains a few pigments, so babies and infants have blue-grey eyes. The definite colour of the iris is established at the age of 10 to 12 years. In infants, muscle fibres that dilate pupil are poorly developed, therefore the pupil is narrow (2 – 2.5 mm). By the age of 1-3 years, pupil size becomes the same as in an adult (3 – 3.5 mm).
  • Lens
  • It is the second major optical system, which accounts for approximately one-third of the eye’s refractive power (up to 20.0 D). The lens has the ability to change the curvature of the anterior surface and to contribute to the clear vision at different distances (accommodation function). The shape and size of the lens varies considerably depending on age. In new-borns, the shape of the lens is almost spherical, its thickness is about 4 mm, the diameter is 6 mm, and the curvature of the anterior surface is 5.5 mm. In young adults and elderly, the thickness of the lens reaches 4.6 mm and the diameter increases to 10 mm; at the same time, the curvature radius of the anterior surface increases to 10 mm, and of the posterior – to 9 mm. subsequently, the refractive power of the lens changes: it is 43.0 D in children and decreases to 20.0 D in adult.
  • Retina
  • Retina is the most important part of the visual analyser, its peripheral unit. The complex structure of the retina allows it to perceive light and convert light energy into nerve impulses, which are then transmitted through a neuronal chain of to the visual cortex where visual information is perceived and processed. Retina is the inner layer of the eyeball; the most important place of retina is the macula with its central area of ​​0.075 mm (fovea centralis). This area has the best perception of visual stimuli.
  • The anterior chamber of the eye
  • The anterior chamber of the eye is delineated in front by the posterior surface of cornea, at the periphery (in the corners) – by the iris radix and the ciliary body, in the back – by the anterior surface of the iris, and in the pupil area – by the anterior capsule of the lens. At birth, the anterior chamber of the eye is already formed, but it’s the shape and size differs greatly from the anterior chamber of the adult eye. This is due to the short antero-posterior axis of the eye, the shape peculiarities of the iris and spherical shape of the lens.
  • About 5% of children are born with closed orifice of the nasal tear duct but, under the action of tear fluid, this orifice opens during the first days of life, and the tear fluid is drained normally. Otherwise, congestion of the tear fluid leads to dacryocystitis of the new-born.
  • Orbit
  • Orbit is the bone structure for eye protection. In new-borns the horizontal diameter of the orbit is bigger than the vertical one, the orbit has a small depth and a shape of a triangular pyramid whose axis is facing forward, which sometimes can give an impression of convergent strabismus. Only the superior wall of the orbit is well developed. At the age of 8-10 years, the shape and size of the orbit are almost the same as in an adult.

According to ophthalmologists, the visual acuity of a newborn is extremely low (0.005 – 0.015). In the first months of life it gradually increases to 0.01 to 0.03, at the age of 2 years it rises up to 0.2 – 0.3 and only at 6-7 years it reaches 1.0.

Regular visits to an ophthalmologist are very important. In order to identify congenital diseases (cataracts, retinal tumours – retinoblastoma, glaucoma) and inflammatory diseases the first examination of the child should be done in maternity. It is mandatory to examine premature born babies to exclude retinopathy of prematurity and optic nerve atrophy. The first year of life is a period of intense development, so visits to the ophthalmologist should be done at six months and at one year.

The novel device available at Optisan Clinic offers real-time following information:

  • Measurement of eye refraction;
  • Corneal reflex analysis (symmetrical or asymmetrical);
  • Measurement of pupil diameter in both eyes and pupil distance;
  • Build up the eye-fixing image.

A unique feature of this autorefractometer is the ability to obtain accurate refractive binocular measurements at a distance of 1 meter without pupil dilation. Measurements are performed simultaneously in both eyes. The device can be used in children of all ages, including children with nystagmus and in non-cooperating patients.

The technique of measurement of the autorefractometer is based on dynamic photoskiascopy (infrared radiation). Infrared radiation is harmless to the child’s eyes; it is present in the day light and is invisible to a human eye.

During the examination, the infrared rays are projected onto the retina through the pupil. Depending on the refractive error, the reflected light generates a bright image inside the pupil.

A medical exam resembling a game!

Diagnosis in children, especially young children, has always been more difficult. Unlike an adult, a kid cannot meet all the doctor’s requirements. He revolves his head, rarely stays quiet, and cannot focus his sight for a long time.

All measurements completed with the new generation autorefractometer are performed in an interactive way, resembling a game: the camera generates a special sound, catching the attention of the child, and the screen displays a smiling face. The procedure lasts just a few seconds, it is non-contact, so that the child does not get tired and does not feel any discomfort.

Regular visits to the ophthalmologist are as important as regular vaccinations and visits to the pediatrician. Unfortunately, the brief examination of the ophthalmologist at the polyclinic, kindergarten or school is not always able to provide a complete idea about the child’s eye health. The fact that you do not have vision problems does not guarantee that your child will have a good vision. Opposite, myopia in one of the parents may not affect the child’s vision. However, it is advisable to consult a specialist.

Outdated technologies for testing visual acuity by means of wall chart are still used in hospitals, kindergartens and schools. Such a test does not provide a satisfactorily complete condition of visual health, as sometimes a latent myopia or a hypermetropia, which in several cases requires optical correction, may be overlooked.

The Optisan Clinic offers a comprehensive diagnosis of the visual system, a consultation of an ophthalmologist with experience in pediatric ophthalmology, able to properly assess the condition of the child and, if necessary, initiate an effective, individualized treatment. New Generation Computerized Diagnostic Devices used in the Optisan Clinic for examining children provide a very high accuracy of the data obtained.

Diagnosis in children, especially young children, has always been more difficult. Unlike an adult, a kid cannot always meet all the doctor’s requirements, often cannot accurately assess his perception and may give unclear answers. Therefore, the devices used in diagnosing children are designed in such a way that the test results do not depend on the precision of the child’s actions.

It is important to note that methods of investigation and diagnosis for children, used at Optisan Clinic are based on modern non-contact equipment. If during the exam the doctor reveals some vision problems, the child will receive the indispensable treatments and will be closely monitored.

Measurement of refraction is performed with autorefracto / keratometer. Currently there are special autorefracto / keratometers for children; these do not require exact eye fixation and even follow the movements of the eye. These devices measure both the refraction of the entire optical system and the cornea (one of the natural lenses of the eye) separately, which is very important in case of astigmatism.

Modern diagnosis entails examination of the eye fundus with pupil dilated. New generation drugs, harmless and easily tolerated, are used for the dilation of the pupil.

The Optisan Clinic offers an early diagnosis of eye disease, providing the opportunity to start treatment as early as possible when the disease has not yet had a significant impact on eye function.

Good vision is a crucial condition for a happy life of any child. According to global statistics, millions of children suffer from various eye conditions: myopia, hypermetropia, strabismus, astigmatism, amblyopia. Ophthalmologists have stated that over the last 10-15 years, the number of children with pathologies of the visual system has increased significantly.

The ability to see the surrounding world well is very important for a child, because only a good vision offers an adequate perception of all aspects of the environment. For smaller children, it is important that the visual system develops properly. The teenager has other problems: overuse of the eyes at school causes visual fatigue, which may lead to serious illnesses.

Paediatric ophthalmologists warn parents that starting solving vision problems as early as possible will bring greater chances to treat them and to have a good prognosis. In childhood, the visual system is very flexible, being more responsive to treatments than in adults.

That’s why it is very important not to miss the right moment!

Functional development of the eye begins immediately after birth and lasts until the age of 12-14 years. That’s why it is much easier to treat most of the eye diseases in childhood, with no surgery, but this requires a prompt diagnosis and timely commencement of the treatment.

Do not wait until the “hidden” problem becomes obvious!

Attend a specialist to make sure your child’s visual system develops properly.

Optisan Clinic offers you a complete diagnosis of visual conditions. The ophthalmologist gives you details on the established diagnosis and medical prognosis of the visual system condition and also creates personalized programs for prophylaxis and treatment. These individualized treatment programs are developed taking into account not only the condition of the patient’s visual system, but also his age, personality, lifestyle.

Specialists at the Optisan Clinic have wide experience working with children of different ages. They use the most modern techniques and are trained in the psychology of young patients. This allows offering an effective and comfortable treatment, which is particularly important for both children and their parents.

Vision is important at any age. Children explore the world by means of their eyes, adults make visual efforts at their workplace, the elderly preserve their vision for evenings spent with grandchildren.

We accept clear vision like something natural and notice changes only after the age of 40 years. Some people attend an ophthalmologist for the first time at this age.

In my career as an ophthalmologist, with many years of professional experience, I have encountered numerous cases of late established eye disorders. I strongly support the presumtion that there is an imperative must for early prevention and screening of ophthalmic disorders and refractive errors, in order to give my patients a real chance of having a good vision.

For several years I have focused on pediatric ophthalmology, for the reason that I consider children being a vulnerable category. Contemporary diagnostic devices allow assesment of refraction at a very young age, even under the age of one year. That’s why I encourage you to attend an ophthalmologist in the first year of your child’s life. If there are no concerns or family history of eye conditions, the first visit can be postponed until the age of 3 years.

A correct and personalized therapeutic approach at a young age greatly increases the chances of recovery of the child’s vision and, unreservedly, his / her optimal intellectual development, as well as his / her school performance.

I’m waiting for you at the Optisan Clinic to answer all your questions regarding the health of your eyes.

With kind regards,

Dr. Alexandru Dimitriu

The child receives more than 90% of the information through vision. Therefore, if the vision is poor, this may affect the child’s development in the future. Subsequently, in order to detect possible diseases at early stages, it is important to consult an ophthalmologist once a year, even if no complaints.

Glasses: to wear or not to wear?

The most common conditions that require wearing glasses from childhood are astigmatism, myopia and hypermetropia. Wearing glasses cannot be neglected in any case, as it is an important part of the treatment. However, it should be stressed that the outcome of the treatment, namely a good vision of the child in the future, depends largely on choosing the proper correction!

Usually, in hypermetropia, glasses are prescribed for permanent wearing. In childhood, uncorrected hypermetropia may lead to the development of amblyopia (lazy eye) and convergent strabismus. Early detection of hypermetropia (2-3 years) and its proper treatment can prevent the development of these conditions.

As for myopia, most children need glasses for vision at distance, and some of them – also for reading (when myopia exceeds 5-6 diopters). Unfortunately, due to the association of degenerative changes in the layers of an eye with myopia, glasses cannot always correct the vision good enough.

In astigmatism glasses are with cylindrical lenses, and are worn in the way prescribed by the doctor (either permanently or just for activities at near).

Regardless of the diagnosis, at Optisan Clinic physicians have an individualized approach to prescribing optic correction and always assess the patient’s tolerability of glasses.

There is an alternative!

If your child definitely refuses to wear glasses, the ophthalmologist at the Optisan Clinic can offer you an alternative method of correction – contact lenses. The doctor always considers both child’s age and psychic characteristics. Choosing contact lenses of any complexity is done from a young child’s age. Contact lenses are a modern, excellent correction method and can be prescribed even to very young patients.

However, in order to preserve the health of children’s eyes, it is necessary to observe some rules, and namely:

  • Contact lenses for your child must be selected by a physician based on the results of diagnostic tests performed with modern equipment;
  • Buy only lenses of good quality and only in a specialized clinic.
  • Keep and maintain the contact lenses properly, do not wear them longer than the indicated wearing time.
  • Also, remember that the lens is a foreign body in the eye, so it is necessary to consult an ophthalmologist regularly.

Diagnosing and initiating an early treatment of strabismus should be the goal of parents and ophthalmologists, because the most important period for developing of a normal vision of both eyes and binocular vision (space vision) is the period of up to 2 years.

Any imbalance unsettled during this period may lead to lack of development, impossible to solve later, even if the position of the eyes can be corrected. Strabismus can cause a delay in the child’s mental development.

Dr. Alexandru Dimitriu is answering the questions of the viewers.

Generally, the treatment of strabismus is a complex one. The treatment choice depends on many factors: the age of the patient, the causes of strabismus and the direction of deviation.

Treatment methods include: wearing eyeglasses, therapeutic treatment and surgery (if necessary).

Dr. Alexandru Dimitriu presents the treatment after establishing the diagnosis of strabismus and, also, the importance of optical correction.
