A squint is the condition when the right and left eye look in different
directions. So, while one eye seems to look straight ahead, the other
will appear to look left or right, or up or down see.
An adult who has a squint or weakness of their eye co-ordination
may notice double vision, blurred vision or head-aches. The
squint may have been present for years or may be more recent.
The websites here and
here explain the condition in more detail.
Some times the eye that
is not doing the work, that is the eye that turns left or right
whilst the other looks straight ahead is a 'lazy' or 'amblyopic'
eye. Amblyopia in adults is not curable..although an operation
may make the lazy eye point in the same direction as the good eye...the
eye still will not see any better after the operation. |

- a longstanding eye muscle weakness, with or without amblyopia
- injury
- thyroid eye disease
- brain diseases in the elderly, such as a third nerve weakness
due to diabetes or hypertension
- many other conditions including multiple sclerosis, myasthenia,
eye surgery, brain problems

- investigate and treat the cause
- orthoptic exercises
- prisms
- surgery

| Orthoptic
exercises may help to
reduce some or all of the symptoms in an adult. |
| Prisms may
be used in the treatment of double vision. A type of prism called a
Fresnel prism will ‘stick’ onto
the lens of a pair of glasses and will join the double images.

There is no upper age limit for squint
surgery. Orthoptic testing will assess whether surgery will
help.
- Basically, if the squint is large surgery will help cosmetically
animation;
- if the squint is small but there is double vision, surgery may
help, often with adjustable sutures
