Symptoms of indirect strabismus

summary

Intermittent exotropia is a kind of strabismus between exotropia and concomitant exotropia. It refers to the fact that the visual axis is often separated, which initially occurs when looking at the distance. When looking at the distance, the fusion divergence amplitude exceeds the fusion convergence amplitude, that is, exotropia occurs. Before intermittent exotropia occurs, exotropia occurs first. What are the symptoms of indirect strabismus? Let's talk about it

Symptoms of indirect strabismus

Intermittent exotropia often occurs in the early stage of children. At first, it occurs only when looking far away. With the progress of the disease, the frequency and time of intermittent exotropia increase. Finally, exotropia can occur when looking near. The oblique period of intermittent exotropia often occurs when tired, sick, drowsy or inattentive.

Intermittent exotropia can cause temporary diplopia in children with immature vision, which will soon be inhibited and have abnormal retinal correspondence. The common symptom is photophobia. In the outdoor sunlight, one eye is often closed, and the reason is unknown. It is estimated that the patient is looking at distant targets outdoors,

There is no near object stimulation to make the two eyes gather. The bright sunlight flashes the retina and interferes with the fusion. The patient changes from exophora to obvious, but it is not certain that the patient closes one eye to avoid diplopia. It is possible that the bright light affects the fusion range of intermittent exotropia patients and makes one eye close.

matters needing attention

Choose a quiet place, or sit or stand, relax the whole body, remove distractions, open your eyes, keep your head and neck still, and turn your eyes alone. First, gaze directly below, slowly turn to the left, then turn directly above, to the right, and finally return to directly below. In this way, turn clockwise for 9 turns. Then turn your eyes from the bottom of your gaze to the right, to the top, to the left, and then back to the bottom. In this way, turn 6 times counter clockwise. Four times in all. Every time you turn, your eyeball should reach its limit as much as possible. This eye blinking method can exercise eye muscles, improve nutrition, and make eyes flexible and bright.
