Strabismus is the failure of both eyes in keeping proper alignment and prevents it from working together. If you have this case, one of your eyes would look directly to the subject you are viewing while the other can either be looking inward, outward, downward or upward.
- Esotropia is the case when the misaligned eye is focusing inward.
- Exotropia is when it is focused outward.
- Hypertropia is when one eye is focused upward.
- Hypotropia is when the other eye is focused downward.
This disorder can either be intermittent or constant. Misalignment can affect both eyes which is called unilateral strabismus or the two eyes would have alternating turns of being misaligned which is called alternating strabismus.
Signs and Symptoms of the Eye Issue
The signs and symptoms of this eye issue can be easily detected since the misalignment is completely visible even without the use of professional instruments. Hirschberg test or corneal light reflex test is the screening test for this eye problem where the eye alignment is evaluated depending on the reflectionsâ location in the eyes when light is shined on it.
The large angle type of this condition usually doesnât cause a lot of symptoms, which leads to amblyopia since the brain is not putting much effort in straightening the eyes. It would not usually cause any headaches and eyestrain.
On the other hand, those with small angle type of this eye problem would most likely suffer from disruptive visual symptoms. Some of its symptoms are eyestrain, headaches, inability to comfortably read, jittery or unstable vision and fatigue whenever you are reading. These are most common for those with alternating or intermittent condition. However, those with unilateral or constant condition would eventually lead to amblyopia with the other misaligned eye.
There are six external muscles in each eye. These are responsible for controlling eye position as well as its movements. This means that these muscles must be coordinated properly to create normal binocular vision. For those with this eye problem, there are anatomical or neurological problems interfering with the overall function and control of all six extraocular muscles.
Genes also play an important part on the kids having this eye condition. If your spouse or you have this eye condition, then there is a great chance that your kids will also develop the eye problem.
If your child develops accommodative esotropia or the eye problem, where your child is farsighted and tries focusing on compensating for the uncorrected farsightedness, he or she may develop this eye condition. It is the condition where the eye would cross because of the excessive effort on focusing. This condition can either occur before reaching 24 months or in the later years of childhood. It can be corrected through the use of contact lenses or eyeglasses.
Another treatment for basic strabismus is lasik eye surgery. It is considered as the most effective method of treating the eye problem where your general eye doctor would refer you to a professional ophthalmologist conducting the surgery.
Vision therapy can also be a great non-surgical treatment and can be done in a certain period of time. Thus, it requires working closely with an orthopedist and surgeon instead of an optometrist.
