Parents are very concerned about whether their baby’s eyes are normal or not. But babies can’t talk yet, so how can we find out if there are any abnormalities in time? One, transparency. People often compare the eyes to the windows of the soul, as windows should be transparent and bright first. Therefore, parents can first observe the black eye of the baby’s eye, that is, whether the cornea is transparent, whether there are white spots on the cornea, vascular texture. Certain congenital abnormalities of the cornea can cause a loss of corneal transparency and the appearance of neovascularization in the cornea, which can seriously affect vision. The junction of the cornea and the sclera, that is, the junction of the black eye and the white sclera has a localized bulge. Teratomas and cortical cysts of the cornea are often found here, which can also affect vision due to the presence of severe astigmatism. Second, size. Next, you should observe whether the eye is particularly large or small. The diameter of the cornea of an average sized eye is about 11 mm, and if it is particularly large, while the cornea is cloudy and foggy, it may be congenital glaucoma, commonly known as “bull’s eye”. If the eye is particularly small, it may be congenital microphthalmia, ocular atrophy, etc. Some babies also find that their eyes are different sizes or both eyes are small, like they can’t open their eyes, and they tend to lift their heads to look at people, which is called ptosis. Third, whether there is a white reflection in the center of the pupil. The lens in congenital cataracts can have varying degrees of white clouding. Retinoblastoma can also have white changes in the pupil area, and certain diseases of the retina such as Coat’s disease also have white reflections. Fourth, mobility and stability. Infants under six months of age may have different eye movements than adults because neuromuscular development is not yet complete. After six months of age, it can be observed that both eyes can move in concert, turning up, down, left and right at the same time and the amplitude of movement is consistent. If there is a constant back and forth twitching of the eyes, this is a possible nystagmus. If there is a light shining on the cornea and the reflection on the cornea is asymmetrical, one in the center and one on the lateral side of the cornea, then there is a possibility of strabismus. V. Gaze ability. The baby can stare at the target that attracts him, and can follow the movement of the target and turn, if it is shown to be blind, or not interested in the outside world, it is possible that the vision is abnormal. Of course, it is better to have the ability of each eye to see the target, sometimes one of the eyes has good vision and the other has bad vision, although it can also gaze at the target, but the abnormal eye cannot be detected. At this time, you can consciously cover one eye. If you find that one eye is covered, indifferent, and the other eye is covered, the baby is irritable and uses his hands to lift the cover, which means that the former eye has an abnormality. Sixth, whether tears. The newborn baby is not yet well-developed tear glands, so there are no tears when crying. Later, if you find that your baby is always tearful or even has a mucopurulent discharge from the corner of the eye, you should pay attention to whether there is an eyelash inversion or an inverted eyelash. If you press the inner corner of the eye and sometimes there is sticky discharge from the corner of the eye, you may have congenital lacrimal sacculitis. If parents find any of these conditions, they should go to the ophthalmology department of the hospital to get a diagnosis and early treatment as soon as possible.
