What causes a squint?
There are many things that may cause a squint. Often a squint in adults is a consequence of a squint as a child. Or squints may be as a result of trauma to the eyes or there may be rare conditions, such as thyroid eye problems. So people who have thyroid eye problems may get misalignment of their eyes which is unusual. This may also occur with neurological diseases such as multiple sclerosis or myasthenia gravis, and in those cases, the onset is often sudden and gives a double vision.
Similarly, in the elderly age group, it may be the consequence of a mini-stroke. So people will suddenly notice double vision and when you investigate them there is an underlying neurological cause.
