A droopy eyelid (ptosis) can also be corrected using surgery.
Encouraging the use of the eye
A number of different treatment options can be used to encourage your child to use the affected eye. These are outlined below.
Using a patch
Using a patch is known as occlusion. It involves placing a patch with a sticky rim over the "good" eye so the lazy eye is forced to work. It can be very effective in improving the sight in the lazy eye.
The length of time the child will need to wear the patch will depend on how old they are, how serious the problem is, and how much they co-operate with wearing the patch.
The orthoptist and ophthalmologist will determine how often follow-up checks are needed.
Patches are most effective before a child reaches five years of age. Most children will need to wear the patch for a few hours a day for several weeks.
While the patch is on, the child should do close-up activities, such as colouring, reading or schoolwork. Patches can be worn with glasses.
Using a patch to treat a lazy eye can be a time-consuming process, and can sometimes be an unpleasant experience for the child.
It's important to explain the reasons for using a patch, and the importance of sticking with the treatment, to your child so that they're motivated to do it.
Atropine eye drops can be used to blur the vision in the good eye. They expand (dilate) the pupil of the good eye and blur near vision, which encourages the use of the lazy eye.
Side effects that can occur after using eye drops include:
