Causes, Treatment, and Prevention of Broken Blood Vessels in the Eye image 1

During the cold winter season, chilly winds blow often, the air is dry,

and immunity also tends to weaken, so

the likelihood of developing various conditions is higher.

Among them, there are many cases where people complain of discomfort

due to broken blood vessels in the eye, and this can occur not only in

winter but also in the hot and humid summer months.

Today, I will explain in detail the causes and symptoms of broken blood vessels in the eye,

diagnosis methods,

treatment methods, and prevention methods.

The thin membrane covering the white part of the eyeball is called the conjunctiva,

and when bleeding occurs in the blood vessels within this conjunctiva,

the phenomenon of broken blood vessels in the eye appears.

As a result, blood gradually collects under the conjunctiva,

and when viewed from the outside, the white part of the eye appears red;

this is called subconjunctival hemorrhage.

It can be caused by epidemic keratoconjunctivitis or conjunctivitis, but it can also appear

from rubbing the eye lightly or from severe vomiting or sneezing.

It is not accompanied by any particular symptoms, but because blood has pooled

when the eyeball is viewed with the naked eye,

it may look unsightly.

Fortunately, vision does not decline, and even if proper

treatment is not carried out, after about 2 to 3 weeks

it gradually fades and the broken blood vessels in the eye improve.

In general, it heals naturally, so you can respond by observing it over

a certain period of time,

but the story changes if there is a corneal injury.

The cornea is located on the outermost surface of the eyeball,

which protects the eye, and because it is easily exposed to the outside,

it can be easily injured even by a minor impact.

If the broken blood vessel is caused by the cornea, it may be accompanied by pain,

frequent tearing, and in severe cases, a gradual decline in vision,

so special caution is needed.

The period required for the absorbed blood to clear varies depending on the extent of the broken blood vessels,

but it generally tends to recover after 2 to 4 weeks.

However, if the symptoms recur or continue for a long period,

you should visit a related clinic and consider appropriate treatment methods.

After treatment, some bruise marks may remain on the affected area,

and artificial tears, one of the treatment methods,

help improve the symptoms.

They do not restore the already broken capillaries,

but to prevent the condition, not only proper treatment methods

but also improvements in daily habits are important.

If you usually wear contact lenses, there is a higher chance of corneal injury,

and in this state, you should avoid using contaminated cleansing solutions.

Even if you have dry eye syndrome, using contaminated eye cleansing solutions can lead to other eye diseases,

and the habit of rubbing your eyes frequently should also be improved.

The eye has antibiotics and an immune system, so as much as possible,

I hope you do not create situations that expose you to viruses through actions that may cause symptoms.
