Symptoms of viral and bacterial keratitis

The symptoms of viral keratitis and bacterial keratitis include eye pain, fear of light, tears, etc.

1, eye pain

due to the invasion of pathogenic factors into the cornea, leading to limbal vascular network congestion, inflammatory secretions and inflammatory cell stimulation, leading to the destruction of corneal structure, resulting in eye pain.

2, fear of light

Because the cornea contains rich sensory nerve fibers, inflammation stimulates the cornea, leading to increased sensory nerve sensitivity, strong light stimulates the cornea will cause corneal pain and foreign body sensation, resulting in fear of light.

3, tears

due to inflammation stimulates the cornea, leading to increased sensitivity of the corneal lacrimal gland, resulting in excessive secretion of tears, tears phenomenon.
