Esotropia

Introduction The intraocular oblique is mostly characterized by esotropia, which is commonly called cross-eyed eye and is the most common type of strabismus. The symptom is that the eyes are skewed to the nasal side. Some children are born with this condition, but most of the esotropia begins to appear around the age of two to three. Some cases can be corrected with appropriate glasses, because the glasses can alleviate the situation of esotropia caused by excessive adjustment of the focal length; however, in some cases, after treatment with glasses and covering, it is still necessary to correct with eye muscle surgery.

Cause

The cause of intraocular oblique:

The eyeball is controlled by 6 extraocular muscles to move in all directions. If the force that dominates the inner rotation of the eyeball is too large or the force that causes the eyeball to rotate outward is too small, the eyeball will be in the adducted position, resulting in an internal oblique. Therefore, the internal rotation tendon and the external rotation muscle paralysis will produce an internal oblique, and the internal oblique produces ipsilateral diplopia. Normal eyes can see light reflections on the cornea. If the eye position is positive or pseudo strabismus, the light reflection point is in the center of the pupil; if it is true strabismus, the light is not reflected in the center of the pupil.

Examination of the intraocular oblique examination:

Mainly do eye examination, brain CT to exclude intracranial organic lesions. Intraocular transtensor tendon and external transversal muscle paralysis can produce intraocular oblique, and internal oblique produces ipsilateral diplopia.

Both intra-balloon tendon and external transversal muscle paralysis produce intraocular oblique, and internal oblique produces ipsilateral diplopia. Specifically check the ultrasound of the eyes to see if there are any genetic problems with abnormalities, whether there is liver or spleen, liver and kidney deficiency and lack of nutrition, check the blood vessels, whether there is muscle loss, vitamins, etc. A certain relationship, pay attention to observe reasonable nutrition.

Differential diagnosis

Symptoms of confusion within the eyeball:

Most babies under one year of age seem to have esotropia. Because the bridge of the nose is wider, it is common for the oriental people to have the inner suede, so that the white eyes look very little. In appearance, the black eyeballs of the two eyes (the cornea) are like the "cross-eyed eyes" that are "fighting" across the bridge of the nose. In fact, the eye position is positive. This phenomenon of pseudo-esoteric gaze is more pronounced when the baby is looking at the left and right sides. We can check it with a flashlight. Normal eyes can see light reflections on the cornea. If the eye position is positive or pseudo strabismus, the light reflection point is in the center of the pupil; if it is true strabismus, the light reflection point is off the center of the pupil. Fortunately, this phenomenon will automatically disappear when the baby grows up (because the nose is taller). However, this makes parents or grandparents mistakenly believe that all esotropia situations will automatically disappear. Because of this erroneous concept, many parents delayed the time for their children to go to the ophthalmologist, and missed the golden age of treating strabismus. True esotropia does not automatically disappear with age.

Intraocular transtensor tendon and external transversal muscle paralysis can produce intraocular oblique, and internal oblique produces ipsilateral diplopia.
