The treatments for different types of keratitis are also different. We should also pay attention to the care and prevention of keratitis.

1. Bacterial:

Acute onset, history of corneal trauma or contact lens wearing, photophobia, tearing, pain, visual impairment, eyelid and conjunctival edema, ciliary congestion or mixed congestion, corneal ulcer, and anterior chamber abscess.

2. Fungal:

The onset is slow, with a history of vegetative corneal trauma or long-term use of hormones and antibiotics. The irritation symptoms are mild, with white or milky ulcers, and the anterior chamber abscess is grayish white, sticky or pasty. simple

3. Herpes virus:

Primary cases are common in young children, with fever and swollen preauricular lymph nodes; recurrent cases are mostly unilateral.

4. Acanthamoeba:

History of corneal contact with contaminated water sources, mostly unilateral disease, radial keratitis, central or paracentral annular infiltration of the cornea or central discoid lesions.

5. Stromal Keratitis:

The most common late manifestation of congenital syphilis is adolescent onset, unilateral, more common in females than in males. In the early stage, sectoral keratitis infiltration and KP are seen, and deep stromal neovascularization appears later.

6. Mooren's ulcer:

It is more common in adults, with severe eye pain, photophobia, tearing, decreased vision, corneal perforation, corneal scarring and vascularization. Keratomas: Slow onset in both eyes, night blindness as early manifestation, decreased tear production, Bitot spots.

7. Superficial punctate keratitis:

Foreign body sensation, photophobia, mild visual impairment, and punctate staining of the corneal epithelium.

8. Filamentary keratitis:

Foreign body sensation, photophobia and tearing, symptoms aggravated by blinking and relieved by closing eyes, filaments can be seen on the cornea, and small grayish-white subepithelial opacities can be seen below the filaments. Recurrent

9. Corneal epithelial erosion:

Eye pain occurs at night or early in the morning, accompanied by red eyes, photophobia and tearing. In severe cases, there is tearing pain, obvious foreign body sensation and irritation, and swollen eyelids. In severe cases, it may cause endophthalmitis.

10. Exposure:

The lesion is located in the lower 1/3 of the cornea. In the early stage, the cornea and conjunctival epithelium are dry and rough, the conjunctiva is congested and thickened, and the corneal epithelium is defective.
