Vision occurs through coordinated work of the eye and brain. Normally, images in the outside world come to our eyes as neural stimuli. If for some reason the image in both eyes cannot be converted to a single image, a weaker warning reaches the brain from one eye. This results in lower vision. In the lazy eye, the eyes are completely normal anatomically.
Eye laziness occurs in 2-3 out of 100 children. Without early detection and treatment, it is the most common visual problem in young adults. Eye laziness is a serious and financially burdensome social problem that affects the child psychosocially in life, job selection, school and friendship relations, and loss of the healthy eye for any reason. Therefore, early diagnosis is very important. In the developed countries, vision scans are performed in nurseries in order to diagnose laziness early. In our country, these screenings should be started to be widely used at an early age.
What can be done to protect children from laziness?The earlier the lazy eye is caught, the more successful the treatment and the shorter the time. Therefore, even if there is no complaint, routine eye examination is required between 6 months to 1 year, 3-5 years and around 7 years. In addition, the following symptoms should be seen immediately after birth pediatric ophthalmologist (pediatric ophthalmologist) should be consulted: • Strabismus, premature birth, whiteness in the eyes, eye trembling • Close or side of the object to look at the head or shoulders by lifting the jaw • Eye rubbing, blinking, stretching opening • Squinting or closing one eye • Use of glasses in the family or laziness
Types and causes of lazy eye1- Strabismus lazy eye: Since strabismus eyes cannot look parallel, laziness develops in the sliding eye. As it is too late to take it to an ophthalmologist, treatment becomes difficult and even irreversible and permanent. Strabismus is the cause of laziness.2- Anisometropic lazy eye: High refractive error in one eye or both eyes, ie situations requiring glasses cause laziness.3- Deprivation (deprivation) lazy eye: Laziness develops if treatment is delayed in diseases such as ptosis, low valve, cataract, corneal opacities, intraocular hemorrhage. Lazy eye can only be treated after actual discomfort.4- Organic Eye Laziness: 10 percent is encountered, it is difficult to return to see. Optic nerve hypoplasia occurs in the presence of coloboma (innate or underdeveloped congenital eye nerve), myelinated nerve fibers.
How is lazy eye treated?The basis of the treatment of lazy eye is to strengthen the neural connections with the brain by operating the lazy eye. • Firstly, eye examination is performed and glasses are given if necessary. • The intact eye is closed for a certain period of time and the lazy eye is referred to the study. This work can be done at home or in the form of glass work (in which case the child must have a certain age and level of vision). • In infrequent closure-resistant children, the pupil of the intact eye is enlarged and blurred vision is created, ie, drop treatment is used to drive the lazy eye.
Eye lazy treatment is a treatment that requires child, family and physician coordination. The best results are obtained in the first 4 years. Although it is a difficult period for both the family and the child, the results of which are resistant to closure of the child between the ages of 4-7 years are quite good. Eye lazy treatment, which was previously abandoned in the 10s, can be continued until the age of 15 in the light of recent studies.
