Atropine drops - when are these used?
Atropine is similar to the drop we use when examining your child to dilate their pupil and relax their focusing power (acccommodation), but it's effect lasts for up to a week.
By relaxing the focusing mechanism of the eye that has had drops put in, this eye will find things difficult to see (especially if up close, like when reading or playing with small toys). Assuming this blur makes things worse than the vision in the good eye, the brain shifts it's attention to the 'bad' eye and begins to use it, and this makes amblyopia recover.
Atropine can be used when it is difficult or impossible to use patches, and is known to work as effectively as wearing a patch for 2 hours every day. At least 1 hour of close work should be done each day, such as reading and craft.
When do I put the drops in?
Because their efect lasts for 5 days, it is only necessary to put the drops in the good eye on 2 days of the week (one drop). These days can be anywhere in the week, 2 days in a row (Saturday and Sunday for instance are easy to remember). The drops can be put in while the child sleeps if you find this easier to do.
Why has my child shifted their focus from the good eye to the 'bad' one, since the drops started they only look at me with their worse eye?
This is a good sign. The brain will only choose the previously weaker eye and start using it if the treatment is working. Don't be concerned, it does not mean that the 'good eye' is losing vision.
