A patient recently came to the department, led by his father. He was only 16 years old, but had never seen anything since birth because he was diagnosed with Leber’s black haze, a genetically related condition. The retina develops a diffuse degeneration that is not reversible. Vision is generally poor, and some may go blind. There is no effective treatment available. But for this family, the child’s brother, who is just 8 months old, has already been diagnosed with Leber’s black haze as well. It was a bolt from the blue for the family. The parents were expecting another healthy child, but ended up having another child with the disease. A family line of macular degeneration was also recently investigated. The mother had bad eyes and gave birth to seven children, only one of whom was normal, the other six were abnormal, and many of their offspring were abnormal. What exactly can be done to prevent this from happening? If an ophthalmic genetic disorder is found in the family, it is actually not only ophthalmic genetic disorder, but also other genetic disorders. You can go to a hospital that conducts genetic research on genetic diseases for relevant tests, including genetic tests. The most important thing is to go to the hospital around 18 weeks of pregnancy for a genetic test or chromosome test, and if the child you are carrying is found to have an abnormal gene or chromosome, you can terminate the pregnancy. If the child being conceived is normal, the pregnancy can continue and a healthy child can be born. For healthy reproduction in the family and for the well-being of the family, be sure to have the relevant tests and have a healthy child.
