Conjunctivitis is a common ocular disease of keratitis. The difference between the two diseases is only one word. This leads many people to be “stupid and unclear” in the face of two diseases. Some people will treat two diseases. Confusion, and some people think that the two diseases are the same word, so it should be basically the same, and even think that their treatment and medication are similar. But in fact, these ideas are not right. These two diseases are not only “almost”, but “a lot worse”. There is a clear distinction between the two, whether it is from the occurrence, performance, harm or treatment or prognosis of the disease. In terms of aspects, there are more differences. So, what is the difference between conjunctivitis and keratitis? The following answers to you one by one:
1, the location of the disease is different
It can also be seen literally that conjunctivitis and keratitis are diseases that occur at different locations, one that occurs on the conjunctiva and one that occurs on the cornea. In fact, conjunctivitis is an inflammatory disease that occurs on the conjunctiva, and keratitis is an inflammatory disease that occurs on the cornea. The cornea is commonly known as the “black eye” of the common people. The conjunctiva is commonly known as the “white eye”.
The conjunctiva is also called a binding membrane and is divided into a bulbar conjunctiva and a sacral conjunctiva. The bulbar conjunctiva is the surface mucosa of the commonly known white eyeball, and the palpebral conjunctiva is the conjunctiva lining the orbital surface.
The cornea is a transparent film of the black eye that forms the center of the eye. The cornea is a transparent avascular tissue that is completely different from the conjunctiva. Light enters the eye through the cornea, allowing us to see everything.
2, the clinical symptoms are different
There is a clear distinction between the clinical symptoms of conjunctivitis and keratitis, which is also an important basis for identifying conjunctivitis and keratitis.
The main symptoms of conjunctivitis are congestion, foreign body sensation in the eye, photophobia, tearing, etc. If it is bacterial infective conjunctivitis, there will be symptoms of increased eyelid secretion.
The clinical symptoms of keratitis are often heavier, commonly known as white eyes, mainly deep vascular congestion, dark red, clinically referred to as ciliary congestion symptoms; its foreign body sensation is more serious, accompanied by more obvious pain . This is mainly because the cornea is rich in nerve endings, so after the occurrence of keratitis, it is often accompanied by symptoms of eye pain, and this symptom will be aggravated in the blink of an eye, the pain will continue until the inflammation disappears. It subsides; the patient is accompanied by symptoms of photophobia.
Therefore, it is easy to distinguish between conjunctivitis and keratitis from clinical symptoms, where pain is a more sensitive symptom. Clinically, the identification of conjunctivitis and keratitis, based on the judgment of clinical symptoms, combined with fluorescein staining, the corneal surface can be colored, but the conjunctiva is not colored.
3, the severity of the disease is different from the prognosis
Conjunctivitis is what people often call “red eye disease”. Although this disease causes some symptoms in the eye after the onset of the disease, it does not have a harmful effect on the patient’s vision; and the disease is generally self-limiting, that is, It is said that even if the clinical treatment is not taken, the patient can be cured within 10 to 14 days after the illness, and the healing time can be shortened after the corresponding clinical treatment, and can be cured in 1 to 3 days. However, it should be noted that if conjunctivitis develops into chronic conjunctivitis, it is more difficult. First, chronic conjunctivitis is not self-limiting and requires active treatment; it can cause itching, foreign body sensation and visual acuity. Symptoms such as fatigue, mild congestion, and small amounts of secretions can cause conjunctival hypertrophy if the duration of inflammation is long. Therefore, patients with conjunctivitis need to be alert to the formation of chronic conjunctivitis.
And keratitis is a disease with more serious diseases, which is blind and causes patients to have different degrees of vision loss. Keratitis often has a long course of disease and slow recovery. If it is not timely clinical and controlled, it will further develop into corneal ulcers, even corneal perforation, which is very harmful. Patients may eventually need to adopt corneal transplantation to treat them.
Although the condition of conjunctivitis is relatively light, the conjunctiva is adjacent to the cornea, and inflammation is spread. Therefore, when conjunctivitis occurs, it is necessary to actively seek medical treatment, on the one hand, avoid developing chronic conjunctivitis, and on the other hand, avoid developing chronic conjunctivitis. One side avoids harming the cornea and causing keratitis.
