Keratitis and conjunctivitis are among the most common diseases on the ocular surface. These can be manifested as eye discomfort, tearing of the eyes, increased secretions, and congestion of the eyes. It is difficult for ordinary people to identify.

So how do you distinguish between keratitis and conjunctivitis?

Let’s take a closer look below.

What is the difference between keratitis and conjunctivitis?

First, the keratitis cornea, commonly known as “black eyeball”, is a transparent avascular tissue, the light is directed into the eye so that people can see things; and conjunctivitis occurs in the conjunctiva, that is, covering the upper and lower eyelids.And the transparent mucosal tissue on the “eye white” is rich in blood vessels.

Because the cornea is rich in nerve endings, keratitis often has eye pain and aggravation in the blink of an eye. This pain continues until the absorption subsides and is accompanied by photophobia.

Simple conjunctivitis is characterized by foreign body sensation, itching, burning sensation, etc., often without pain and photophobia.

Experts point out that keratitis is a serious blinding eye disease that can cause varying degrees of visual loss if left untreated.

Especially when the pupil area occurs in the center of the cornea, the patient’s vision loss is more pronounced.

The course of keratitis is long and the recovery is slow. If it is not controlled in time, it will further develop into corneal ulcer or even perforation, and eventually corneal transplantation may be needed.

Second, regarding conjunctivitis and conjunctivitis in addition to eye discomfort, eye tears and other symptoms, generally does not affect vision.

Acute conjunctivitis, which is commonly referred to as “red eye disease”, is mostly caused by bacterial or viral infections. It is generally self-limiting. It can be cured at 10-14 hours without treatment. It can usually be 1-3 minutes after administration.get well.

However, if it develops into chronic conjunctivitis, it is more difficult. Generally, there is no self-limiting. Patients will have itchy eyes, foreign body sensation and eye fatigue, mild congestion and a small amount of secretions. If it lasts for a long time, it will lead to conjunctival hypertrophy.
Most conjunctivitis is caused by infection with pathogenic microorganisms and is an infectious disease.

Especially in the spring and summer, people should pay special attention to eye hygiene, avoid rubbing with your hands, and do not wipe the eyes with a towel.

When a single eye is onset, care should be taken to prevent the other eye from being infected.

In general, once the eyes have symptoms such as congestion, pain or foreign body sensation, the patient should not repeat the use of eye drops, and should go to the hospital at the appropriate time for examination and rational use of the medicine under the guidance of a doctor.
