How to determine whether a child has astigmatism in Chengdu Pediatric Eye Hospital

Astigmatism is a common visual problem, especially in children. In Chengdu, there is a hospital specialized in treating children's ophthalmic problems. They use a series of examinations and tests to determine whether a child has astigmatism.

Family history and symptom observation

Before judging whether the child has astigmatism, the doctor will first ask the parents about the family history of the child's visual problems. Astigmatism may have genetic factors, so understanding family history is very important for diagnosis. In addition, the doctor will also ask whether the child has blurred vision, headache or eye fatigue, which are common symptoms of astigmatism.

Next, the doctor will observe the pupil of the child. Astigmatism can lead to abnormal reactions of the pupil, such as excessive expansion or rapid contraction. The doctor will also check the coordination of the child's eye movements and eyelid muscles to determine whether there is a problem caused by astigmatism.

Diopter measurement

Diopter measurement is an important step to determine whether a child has astigmatism. The doctor will use an automatic refractometer to measure the child's refraction. This test is very simple. Only the child needs to look at a target, and the instrument will automatically measure the corneal diopter.

According to the measurement results, the doctor can determine whether the child has normal vision, hyperopia or myopia. However, if the child's vision does not match the diopter, then there may be astigmatism.

Corneal topography

Corneal topography is an advanced test to determine whether a child has astigmatism. This test measures the shape of the cornea to determine the difference in diopter. Corneal topography can provide detailed information about corneal curvature, corneal thickness and corneal morphology.

Corneal topography testing usually requires special equipment and is performed by professional doctors. By analyzing the topographic map, doctors can determine the degree and type of astigmatism of children, so as to provide accurate diagnosis for further treatment.

Fundus examination

Fundus examination is also very important for judging whether a child has astigmatism. The doctor will use a special instrument to observe the child's fundus to determine whether there is damage or other problems caused by astigmatism. Through fundus examination, doctors can understand the condition of the child's retina and eliminate other causes that may cause vision problems.

In general, Chengdu Pediatric Eye Hospital judges whether a child has astigmatism through family history and symptom observation, diopter measurement, corneal topography and fundus examination. The results of these tests and examinations can help doctors develop appropriate treatment plans to improve children's vision and quality of life.

summary

Chengdu Pediatric Eye Hospital uses a variety of methods to determine whether a child has astigmatism, including family history and symptom observation, diopter measurement, corneal topography and fundus examination. The comprehensive application of these methods can provide accurate diagnosis results and corresponding treatment plans for children. Early detection and treatment of astigmatism is very important for children's vision development, so parents should regularly take their children to professional hospitals for eye examinations.
