Summary

The investigators will re-investigate 150 children studied extensively in the past. 100 of these children were born to mothers prescribed methadone during their pregnancy because of opiate dependency, and 50 were comparison children who were not exposed to drugs. These children were investigated when they were newborn babies, and again when they were six months old, and a quarter of the drug-exposed babies had problems with their eyesight, whilst very few of the comparison children has eyesight problems. The investigators would like to see whether the eyesight problems are still present in the children now that they are older. Because they are older, more detailed testing can be undertaken which will help to understand how drug exposure in the womb may have affected their eyesight. The investigators will recruit new, comparison children to the study to match the number of comparison children with the number of drug-exposed children. The findings will be relevant and important when advising mothers on drug use - both prescribed and illicit - when they are pregnant.
