How to recover from traumatic pupil dilation

Many people do not know how to rest their eyes because they look at mobile phones and computers for a long time. Especially for teenagers, while they are growing up, if they always overuse their eyes, it will cause eye damage. Traumatic pupil dilation is a type of ophthalmic disease, which is mostly caused by damage to the pupil. So, how to recover from traumatic pupil dilation? The following is a detailed introduction.

Traumatic mydriasis is mostly caused by damage to the pupillary sphincter, which generally does not recover or recovers only slightly. There are many reasons for poor vision. First, bleeding in the anterior chamber indicates that the anterior pigment membrane must be damaged. Before the inflammation subsides, vision will be affected. Second, a large pupil itself will affect vision. Third, although CT is normal after trauma, it cannot reflect whether the retina and optic nerve are damaged, which can also cause vision loss.

Guidance:

It is recommended to continue drug treatment. The specific drugs will be guided by your attending physician. It is recommended to check electrophysiological ERG and VEP to rule out damage to the retina and optic nerve. As for whether the vision is restored, the decreased vision caused by pupil dilation can be partially corrected by special glasses. The decreased vision caused by anterior uveal inflammation and the mydriatic drugs used in treatment can generally be restored. However, it also depends on whether there are other sequelae after the inflammation subsides. In addition, traumatic cataracts usually take one or two months to appear, and of course they are not sequelae that will definitely appear.

Blunt trauma can cause paralysis or even rupture of the pupillary sphincter, causing the pupil to dilate; it is usually accompanied by traumatic iridocyclitis; in more serious cases, such as anterior chamber hemorrhage, there will be angle recession and possible secondary glaucoma; in a few cases, there may also be subluxation of the lens.

Guidance:

In the early stages, you can apply appropriate hot compresses and use hormonal eye drops to fight inflammation. Those with mild symptoms can usually recover on their own, but those with complete pupillary sphincter rupture are unlikely to recover to their original size, and they react poorly to light, so you must wear sunglasses when going out on sunny days. Dilated pupils will affect the image of objects in the eye, and there may also be problems with accommodation. If blunt trauma also causes problems with the retina or optic nerve, vision will be even more blurred. I don’t know if there is any injury to the fundus.
