How to make sure keratitis is good?

summary

There are no blood vessels in the cornea, so acute infectious diseases are not easy to invade the cornea. However, the corneal tissue participates in the systemic immune response. Although the degree of the immune response is lower than that of other tissues, it is precisely because it has no blood vessels and its metabolism is relatively slow that the changes of the immune response last for a long time. The cornea is in a sensitive state for a long time, which makes it prone to allergic diseases, such as vesicular keratitis. How to make sure keratitis is good? Next, I'd like to share my views with you.

How to make sure keratitis is good?

If there is no eye irritation, no secretions, photophobia, foreign body sensation, blurred vision, you can judge that it is cured! But some viruses will relapse, such as herpes simplex virus caused by keratoconjunctivitis more stubborn, may relapse, also only need to relapse after treatment!

In addition to paralytic keratitis, most patients with keratitis have severe inflammatory symptoms, such as pain, shyness, tears and blepharospasm. Patients with keratitis have not only ciliary hyperemia, but also iris hyperemia. Serious patients with bulbar conjunctiva and even eyelid edema will occur. Keratitis will inevitably affect vision more or less, especially when inflammation invades the pupil area.

The corneal scar formed after ulcer healing not only blocks the light from entering the eye, but also changes the corneal surface curvature and refractive power, making the object unable to focus on the retina to form a clear image, resulting in decreased vision. The degree of vision involvement depends entirely on the location of the scar. If it is located in the middle of the cornea, even though the scar is small, it has a great impact on vision.

matters needing attention

Patients with keratitis should cultivate the habit of cleaning and loving hygiene at home. They should not rub their eyes with dirty hands and handkerchief at will. Their face washing utensils should be boiled and disinfected regularly. Family nursing of keratitis should be done well to prevent repeated infection, aggravate the pain and cause adverse consequences. The family care of keratitis focuses on prevention, especially in modern times, the wearing of corneal lenses (contact lenses) is increasing day by day. It is easy to develop keratitis because of lack of hygiene and improper care. Corneal inflammation should be timely to the hospital for examination, treatment, not delay, so as not to affect vision.
