What Is Exotropia?

Constant exotropia and intermittent exotropia may be different stages of exotropia development. Constant exotropia may be the result of the development of intermittent exotropia. Constant exotropia refers to the fact that an eye is always deflected at any time. It usually develops in infancy and some develop from intermittent exotropia. Early onset and worsening onset, often due to the destruction of binocular vision, resulting in stereo blindness. Surgery needs to be corrected as soon as possible without delaying the operation and causing irreparable consequences. If it is a constant exotropy developed by intermittent exotropia, it is better to recover, because before the strabismus is constant, binocular monoopia has been established, and after surgery, the intact binocular monocular can be obtained again.

Exotropia, one of the ophthalmic diseases, is divided into intermittent and constant exotropia. Intermittent exotropia is a transitional exotropia between esotropia and common exotropia. Sometimes in exotropia, sometimes the patient can control the position of the eyeball. With increasing age, fusion and regulatory functions may gradually weaken, and eventually lose control, lose compensatory capacity, and become constant exotropia. The biggest feature of this disease is the large change in oblique viewing angle. Exotropia occurs when exhausted, distracted, especially when looking far away. If the strabismus becomes significantly more constant, it should be corrected in time.

Types of exotropia

Constant exotropia and intermittent exotropia may be different stages of exotropia development. Constant exotropia may be the result of the development of intermittent exotropia. Constant exotropia refers to the fact that an eye is always deflected at any time. It usually develops in infancy and some develop from intermittent exotropia. Early onset and worsening onset, often due to the destruction of binocular vision, resulting in stereo blindness. Surgery needs to be corrected as soon as possible without delaying the operation and causing irreparable consequences. If it is a constant exotropy developed by intermittent exotropia, it is better to recover, because before the strabismus is constant, the binocular monocular has been established, and after surgery, the intact binocular monocular can be obtained again.

The dangers of exotropia

Whether exotropia is treated in a timely manner is critical for both children and adults. Adult exotropia is a more common type of strabismus in daily outpatient clinics. The older the person, the higher the incidence. Many patients delay the best time for surgery because of "fear of" surgery. When the exotropia first occurs, you can usually control the eye position to the right position. The exotropia is obvious only when the attention is distracted. As the age increases, the eye adjustment ability gradually decreases with the increase of eye strength, and the exotropia becomes difficult to control It seriously affects our appearance, destroys our advanced binocular vision, affects our confidence in life and work, and even causes mental disorders.

Treatment of exotropia

1. The treatment plan for intermittent exotropia is more complicated and should be adapted to each individual. Each child's condition is different and the treatment plan is also different.

2. Intermittent exotropia with small degrees, children with less frequent strabismus can be treated conservatively:

(1), nib training, 5-10 minutes twice a day.

(2) Multimedia CD training. The CD has two types of visual enhancement and Visdon.

(3), wear negative ball lens treatment.

3. Intermittent exotropia with strabismus greater than 30 degrees. Due to the ability to converge, exotropia can no longer be controlled, surgery should be considered.

4. The frequency of ectopic exotropia should be considered surgery.

5. Indications for surgery:

(1) Seeing far (six meters) and seeing near (33 cm), the prism has a squint angle greater than 20 degrees (triangularity)

(2) Intermittent exotropia with binocular vision balance.

(3) Those who have not improved their amblyopia treatment for more than half a year

6. After inspection, the convergence force gradually decreases. Deterioration of stereo function.

Precautions for exotropia after exotropia

1. Avoid systemic infections.

2. Teach patients and their families how to properly apply eye drops. First, the family members or patients wash their hands clean, then the patient takes the supine position and asks his eyes to look upwards. The family member or patient separates the upper and lower eyelids with the thumb and index finger of the left hand, gently pulls the lower eyelids downward with the thumb, and holds the eye dropper in the right. For the vault, tell him to lightly roll his eyes and close his eyes for 1-2 minutes, then wipe off the liquid medicine with absorbent paper. When applying eye drops, the mouth of the bottle is 1-2 cm away from the eyelids. Do not touch the eyelashes. At the same time, take two or more drugs at a time interval of 3-5 minutes. Take 1-2 drops each time. Shake well.

3, pay attention to eye hygiene, do not use your eyes excessively, rub your eyes, avoid eye fatigue, and ensure adequate sleep.

4, diet should pay attention to nutritional intake to be balanced, avoid tobacco and alcohol and spicy food.

5. For patients with refractive errors, timely optician treatment is required after surgery. For children with partially accommodative esotropia, original corrective spectacles should be worn after surgery, and close vision should be avoided as far as possible, so as to avoid adjustment and recurrence of esotropia. If there is amblyopia, amblyopia training should be conducted under the guidance of a doctor.

6. Regular review.

Clinical classification of exotropia

Patients can progress from esotropia to intermittent exotropia and then to constant exotropia, or they can be intermittent exotropia or constant exotropia as soon as they develop disease. Intermittent or constant exotropia can be divided into 4 types according to different clinical degrees of distant and near vision.

1. Basic type: The strabismus degree when viewing far and near is almost equal.

2. Excessive separation type: farsightedness is significantly greater than nearsightedness. (15 )

3. Insufficient type: near-sightedness is significantly greater than far-sightedness. (15 )

4. Pseudo-separation is too strong: farsightedness is significantly greater than nearsightedness, but after covering for 1 hour with one eye or wearing 3D ball lens in both eyes, the obliqueness of farsightedness and nearsightedness is basically equal.
