The keratitis reaction caused by various factors is called keratitis. It is one of the common diseases in ophthalmology and one of the main blinding diseases in China. The cornea is located in the front of the eyeball, which is in direct contact with the outside world. It is easy to be damaged by microorganisms, trauma and physical and chemical stimuli, resulting in inflammation. The clinical manifestations were blurred vision, pain, photophobia, tears and other irritation symptoms, as well as obvious visual loss. How about the symptom picture of keratitis?

How about the symptom picture of keratitis?

In addition to paralytic keratitis, most patients with keratitis have strong 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.

The symptoms of keratitis caused by different causes are different. Bacterial keratitis has the most acute onset, the most severe symptoms, and the secretion is increased and thick; Viral keratitis took the second place, and the secretion was not much, which was watery or mucinous; Fungal keratitis is the lightest, sometimes corneal lesions have been very serious, but patients feel it is not obvious. Corneal perception may decrease in patients with herpes simplex keratitis.

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

If the patient's condition is very serious, or even eye atrophy, blindness, it is necessary to consider corneal transplantation surgery. However, due to the lack of cornea in China. It may take a while. Therefore, we need to be patient, and we also need to be patient.
