A 5 year old child’s eye axis length of 23.56mm is on the high side. A normal 5 year old boy’s eye axis is usually between 21mm and 22mm, but whether it is abnormal or not, further examination is needed to determine. If a child’s eye axis appears to be on the large side it may be that there is an eye vision problem, but it is not possible to determine the child’s exact condition based only on the eye axis length. If a 5-year-old child is found to have developed 23.56mm around the eye, it means that the eye axis is on the long side and myopia may be present. The child will need to go to an ophthalmologist for a timely examination to assess whether myopia is indeed present. If myopia is confirmed, myopia can be corrected with eyeglasses or corneal reshaping lenses as prescribed by the doctor to improve vision. Children should also pay attention to eye hygiene and control the time spent on cell phones and computers. Children with myopia are advised to consult a doctor for evaluation of their condition and treatment as prescribed by the doctor.
