What is the difference between keratitis and conjunctivitis?

Conjunctivitis is pink eye.

Keratitis is more severe, and severe cases can lead to blindness.

Difference Between Keratitis and Conjunctivitis

Keratitis and conjunctivitis are both very common eye diseases, although the two eye diseases are only one word apart, but they are different, so what is the difference between keratitis and conjunctivitis? Let's take a look at the differences!

The difference between keratitis and conjunctivitis

1. The location is different

Keratitis is a disease that occurs in the cornea of the eye, which is a clear eye tissue without blood vessels, through which light can see. Conjunctival strictness refers to inflammation that occurs on the conjunctiva, which is the clear mucous membrane that covers the whites of the eye and contains blood vessels.

2. Causes of the disease

Keratitis is mainly caused by trauma and infection, and the normal and intact corneal epithelial cells are the best barrier against foreign invasion. The ** of conjunctivitis is mostly caused by external infection.

3. The symptoms are different

Although there are some similarities between the symptoms of keratitis and conjunctivitis, the symptoms of keratitis are redness, pain, photophobia, and tearing; Second, conjunctivitis will be manifested as redness, itching, dryness, and a lot of secretions.

4. The impact is different

Keratitis is a serious blinding disease, the condition is mostly critical, and the course of the disease is long, the recovery is slow, if not controlled in time, corneal ulcer perforation can occur, and even cause intraocular infection, severe cases need corneal transplantation. Conjunctivitis does not affect vision and is usually cured within 10 to 14 days, if not **, and usually within 1 to 3 days after medication.

5. Contagion

Keratitis is an infectious disease that is not contagious. Conjunctivitis is contagious, and patients with conjunctivitis are advised not to share their household items with others.

By reading the above article, we can understand that keratitis and conjunctivitis are not the same, we must prevent their occurrence in time in our daily life, and when we can't determine whether it is keratitis or conjunctivitis, the correct way should be to choose a regular eye coarse hospital for examination, and use drugs rationally under the guidance of doctors.

Keratitis generally causes tearing and wiping the eyes, while conjunctivitis feels like there is a foreign body in the eye; Conjunctivitis can be done with anti-inflammatory drugs, while keratitis can be done with hormones.

The three arms they press are different, keratitis occurs in the corneal conjunctivitis, it occurs in the conjunctiva, and the symptoms are also different; It is necessary to carry out relevant examinations according to the doctor's instructions, use relevant drugs and eye drops, solve the disease as soon as possible, and carry out corresponding symptomatic treatment according to the degree of development and mechanism of his disease, and symptomatic according to the different degrees of the disease.

Conjunctivitis is an infectious eye disease caused by bacterial or viral infection, it is recommended that you alternate acyclic guanosine eye drops and haloperic acid eye drops, and do not touch the affected eye and secretions at the mouth of the eye drop bottle to avoid cross-infection.

A: Keratitis and conjunctivitis are both among the most common diseases of the ocular surface. There are some similarities in their symptoms, which can be easily confused with eye discomfort, tearing, increased intraocular secretions, and congestion.

The cornea, commonly known as the "black eyeball", is a transparent non-vascular tissue through which light enters the eye, allowing people to see things, while conjunctivitis occurs in the conjunctiva, that is, the transparent mucosal tissue covering the inner surface of the upper and lower eyelids and the "white of the eye", which contains abundant blood vessels.

Because the cornea is rich in nerve endings, keratitis often has eye pain when attacking, and the symptoms are aggravated when blinking, this pain will continue until the inflammation subsides, and it can also be accompanied by photophobia, while simple conjunctivitis is manifested as a foreign body sensation, itching, burning sensation, etc., and often there are no pain and photophobia.

It should be emphasized that keratitis is a serious blinding disease that can cause varying degrees of vision loss, especially when the lesion occurs in the pupillary area of the cornea**, the patient's vision loss will be more obvious. This eye disease has a long course and slow recovery, and if not controlled in time, it can progress to corneal ulcers or even perforations, which may eventually require a corneal transplant.

Conjunctivitis alone does not affect vision. Acute conjunctivitis is commonly referred to as "pink eye", which is caused by bacterial or viral infection, generally self-limiting, even if it is not **, it can be cured within 10 to 14 days, and it can usually be cured within 1 to 3 days after medication, but if it develops into chronic conjunctivitis, it is more difficult, generally not self-limited, patients will have symptoms such as itching, foreign body sensation and eye fatigue, mild congestion and a small amount of discharge, and the inflammation will also lead to conjunctival hypertrophy for a long time.

Most conjunctivitis is caused by infection with pathogenic microorganisms and is a contagious disease. Especially in spring and summer, people should pay special attention to eye hygiene, do not rub their eyes with their hands, and do not wipe their eyes with towels. In the case of one eye, care should be taken to prevent infection in the other eye.

In short, when symptoms such as eye redness, eye pain or foreign body sensation appear, it is important to avoid the abuse of eye drops and should use them rationally under the guidance of a doctor.
