Bacterial keratitis is the inflammation of the cornea caused by infection of bacteria.
It occurs when the surface of the cornea is bleached, allowing the bacteria to infect the underlying tissues.
Bacteria most frequently responsible for keratitis include Hemophilus, Streptococcus, Enterobacteriaceae, and Staphylococcus species.
Bacterial keratitis usually develops quickly and cause ulceration as the bacteria carves out the corneal tissue.
Some bacteria, such as Pseudomonas, are so aggressive that they are capable of ‘eating’ their way entirely through the cornea, causing perforation.
Once the infection affects the deeper layers of the cornea, scarring may remain even if you have recovered completely from the keratitis.
Depending on the size and location of the scar, it may or may not affect your vision.
Possible complications include irregular astigmatism and if severe, permanent blindness.
To prevent permanent sight loss, you should see your eye doctor to get treated immediately if you are experiencing the following symptoms.
Especially if they appear suddenly.
See a doctor immediately as delayed treatment can cause blindness.
Bacterial keratitis occurs when the corneal surface is breached. This can be caused by several factors which include:
To examine whether the keratitis is caused by bacterial or fungal, the eye doctor will have to gently scrape your cornea for biopsy.
This is important as a wrong course of treatment can aggravate the condition.
Once confirmed, bacterial keratitis is usually treated with antibiotic drops and you may need to see your eye doctor frequently depending on the severity of the condition.
Be prepared for frequent application of the eye drops too.
Sometimes, your eye doctor may also recommend using steroids to speed up recovery.
This has to be considered seriously as using of steroids have always been controversial in regards to its effectiveness.
You may want to seek advice from different doctors before deciding whether to use steroids.
During the healing process, you should remove and avoid wearing contact lens to avoid further irritation and infection.
If you are a contact lens wearer, learning the proper contact lenses management techniques is important to prevent a keratitis infection.
