The last sensory system to develop during life in the womb is vision. From the 25th week of pregnancy, it has been observed that the baby responds increasingly to visual stimuli such as light. Eyelid movements also begin in this period. The baby's eyelids are closed until the 26th week. In reality, the inside of the uterus is not absolute darkness. It transmits light just as it transmits sounds. Therefore, the baby can easily distinguish between day and night. Only one percent of the outside light reaches the unborn baby. However, this amount is sufficient for the unborn baby to perceive colors and store them in their memory. Especially red tones are perceived better. As previously thought, the baby's senses in the mother's womb are not an underdeveloped creature. On the contrary, from a very early period, his senses begin to develop and he knows his environment and stores information in his memory. For this reason, it is beneficial to apply stimuli such as sound, light and touch to the baby in moderation.
Unfortunately, we can see many eye diseases that we see in adults in our children, whom we protect from all kinds of evil and whom we can not associate with any disease. These can be very serious such as cataracts, glaucoma (eye pressure), lazy eye, droopy eyelids, Retinopathy of Prematurity (ROP), Eye Tumors, as well as simple diseases such as infection. In general, eye disorders such as myopia, astigmatism, and hyperopia, which are frequently seen in eye controls, are also frequently encountered in children and infants.
So, are there risk factors for these diseases? Of course, we can answer yes to your question. These are: Family history of hereditary eye disease, Drug use during pregnancy, Contagious diseases with fever during pregnancy, history of premature birth, History of incubator oxygen therapy, Mode of delivery, Postnatal trauma, accident, fall, Fever and Convulsion history.
The average length of a normal pregnancy is about 40 weeks (280 days). According to the World Health Organization, births before 36 weeks are considered premature.
Premature babies are at greater risk for eye problems than full-term babies, and the earlier this risk increases.
Eye tissues have not completed their development before 40 weeks. In a premature baby, especially in a baby receiving incubator and oxygen therapy, the peripheral retinal vascular layer stops before it can complete its development and forms undeveloped irregular vessels. These veins are prone to bleeding.
Retinopathy of prematurity is the name given to the invasion of normal tissue of the retina by abnormal blood vessels and fibrous tissue. ROP causes poor wound healing, retinal detachment, and eventually poor or no vision in the retina. In some cases, complete blindness develops.
All premature babies are at risk of ROP. Very low birth weight babies are at additional risk. The risk is much higher, especially if these babies had to be immediately placed in a high oxygen environment.
It is essential for all babies to undergo an eye examination. However, in premature babies, eye examination is a must. Retinal examination should be performed with special examination methods. And laser treatments may be required in the detection of retinopathy. These babies are eye patients throughout their lives and their controls should be done without interruption.
Drooling in babies is a very important condition. Generally, the blind eye shifts. If there is a deterioration in the vision of one eye, especially in early childhood, a shift occurs in that eye. This situation can sometimes be beneficial and stimulating for families to warn and provide early treatment.
Especially in infancy, high hyperopia is one of the reasons that may cause eye shift. And the eye that fails to focus the two eyes together develops a shift. This results in lazy eye. Sometimes the slippage happens in one eye, while in some cases it can happen in both eyes. Generally, the eye with better vision is preferred. Newborn cataracts can usually be recognized by the white reflex they give before they cause slippage, but if the diagnosis is not made, it can cause slippage in the future. Another issue is the problems behind the eyes. Among these, eye tumors occupy an important place. Eye tumors in children can have a rapid onset and cause white reflex in the eye. While the red reflex in the pupil is normal, especially in photo shoots, it is considered an abnormal situation to see a white reflex.
The first thing to be done in the treatment of slippage in babies is to determine the cause. First of all, when we eliminate the cause, the problem can be corrected, but this situation can cause a troublesome process in babies.
The investment in the child is very important in terms of eye diseases until the first 9 years of age. While many diseases that cannot be treated in this period cannot be treated in later ages, they may cause functional deficiencies.
When to see a doctor is one of the most common questions we come across. Unfortunately, children and babies cannot express what they see less because they are not aware of it. Whether there is a problem in their eyes cannot be noticed until they are examined by an eye specialist, and late diagnosis can cause delays in treatments and problems in a wide area, from lazy eye to loss of the eye.
Early diagnosis and treatment is very important. The first examination should be done immediately after birth, within the first 6 months. In this period, a possible congenital cataract, glaucoma, tumors or developmental disorders, lacrimal duct obstruction, strabismus can be recognized.
Newborn babies are sometimes born before this canal is fully formed. Mostly, the blockage is at the point where the canal should be opened to the nose, and the canal is closed with a thin membrane in this region. This is common in newborn babies. In most babies, this phenomenon goes undetected at birth. Only in some newborns it can be observed as a soft swelling on the nose, between the nose and the eye. But most babies are normal at the time of birth, around 2-4 years old. It starts to show itself with continuous watering and burrs in the eye in weeks. Purulent fluid outflow can be seen by pressing the pouch area. These complaints may increase over time and are usually a condition that resolves by 1 year of age. If the canal is recanalized within the first year, which is a high rate of 90%; complaints are completely gone. However, after the age of 1, the possibility of spontaneous opening of the canal is considerably reduced and medical assistance is needed.
Mothers and fathers who have a newborn baby with duct obstruction usually come to us with the following complaints:
"There was no problem at birth, it was completely normal, or a few days after birth, there was burrs, we used drugs and it passed, there was no problem, but watering started at about 3 weeks - 1 month. Now there is constant burr formation. I constantly have to clean it. I'm on medication, it seems to go away, but then it starts again..."
When the child is 1 year old, if watering and burrs still continue, medical intervention should be considered now. Especially a simple intervention between 12-18 months will be very useful. Delaying the intervention, which is not carried out within this period, until after the age of 2 will not be beneficial. For this reason, probing should be considered in a patient whose duct obstruction has not resolved spontaneously until the age of 1 year. Pressure lavage is performed from the upper punctum by closing the lower punctum before probing. If lavage is not performed, probing process is started. After the tear ducts are checked and lavage is performed in both eyes, the procedure is terminated. It is a procedure performed under general anesthesia (mask anesthesia) and takes about 5-10 minutes. Afterwards, the patient is given antibiotic drops to be applied for the eye and a nasal spray containing sea water for the congestion area in the nose. If the first application is unsuccessful, a second probe can be applied.
Probing is a very successful process in experienced hands. However, in some cases, the channel is opened with probing, but it closes again as the channel's response to healing, and continuation cannot be achieved. In this case, silicone tube application is recommended for children over 2 years old. The tube is left in place for about 2-6 months.
Dacryocystorhinostomy, which is a more comprehensive surgical procedure, should be considered in cases where success is not achieved after all these applications and the obstruction is at the bone level. For this operation, the age at which the child's facial bone structure develops should be selected. The timing of this surgery should be decided according to the severity of the symptoms, the problems of the patient's family, and the infection status.
Thanks to the developing technology, the presence of astigmatism, hidden strabismus (microtropia), high hyperopia and many problems that can cause lazy eye can be easily recognized even in a 1-month-old baby. Thanks to advanced devices, we can make measurements from a certain distance without scaring babies and small children. Thus, we can carry out the treatment of the child without fearing the examination, without even realizing that he is being examined.
Generally, our recommendation is to undergo an annual eye control in infants and children. However, in children who have not been diagnosed with the disease and are not brought to the annual control, the appropriate age for the 2nd control is 3 years after the first control is performed until the age of 1 year. At this age, our child now begins to communicate with us, reacts to the animal pictures we show, and the percentage of vision can be determined. This is a period in which we often encounter lazy eye and can best treat it. It is a period when the phrase "the tree bends when it is wet" is very good for eye diseases. Because amblyopia, which we encounter at later ages, is more difficult to treat, and the later the treatment age, the lower the success.
The third examination time is the pre-school period. Eye disorders encountered in this period affect the vision of children quite a lot. In school-age children, low academic achievement, boredom, indifference to lessons, distraction, tic formation are often associated with eye disorders.
As a result, even if we do not think that there is a problem, we should have our children examined by an ophthalmologist once a year. The best time is the months when the school term starts. Children are not aware of what they see less and treatments that are not done at the right time can cause eye loss.
The eyes of our children are the guarantee of our future.
