Bacterial Keratitis is a sight-threatening infection of the cornea caused by bacteria such as streptococcus and pseudomonas entering through a break in the corneal surface, often due to contact lens misuse or poor hygiene. It can develop rapidly within 24-48 hours and be very painful, resulting in a thick mucopurulent discharge from the eye, tearing, light sensitivity, and inflammation. Without prompt treatment with topical antibiotics and steroids, it may lead to corneal scarring, perforation, or even blindness. Approximately 25,000 Americans develop it annually.

2. The disease!
• FOR ALL YOU CONTACT LENS WEARERS
• Bacterial Keratitis is mainly caused from an
infection of contact lens misuse or
complication of contact lens use!
• It is also a result of an infection of the
cornea!
• Result of injury to the eye/ cornea!

3. OTHER CAUSES
• You can also get this disease from poor
hygiene! So make sure to wash your face and
take showers!
• Poor nutrition is another cause of Bacterial
Keratitis! Like a lack of vitamin A.

4. BACTERIA!
• Some of the
bacteria responsible
for this disease is
streptococcus,
pseudomonas,
Enterobacteriaceae
and staphylococcus
species! *A break in the cornea allows
for these organisms and
bacteria to enter and cause an
infection

5. IT CAN HAPPEN TO ANYONE!
• Approximately 25,000 Americans develop
bacterial keratitis annually!
• Can occur in
both children and
adults!

6. NO FUN AT ALL!
• It can develop very quickly!
• Rapid progression in the corneal
destruction…..may be complete in only 24 to
48 hours!
• Can be very painful!

7. GROSS!
• From Bacterial Keratitis, the person is likely to have a
thick, ropy, mucopurulent discharge from the eye!
• Can cause tearing of the ye and light sensitivity
• Also can cause anterior segment inflammation around
the eye!
• Can possibly reduce vision!
• Bacterial Keratitis can cause cloudiness of the eye.

8. OTHER RESULTS!
• Corneal scarring!
• A hole in the cornea!
• CAN CAUSE BLINDNESS! THIS DISEASE IS A
SIGHT THREATENING PROCESS!

9. TWO TYPES!
• Superficial keratitis
-involves upper most layer of the eyelid
-when healed there is no scarring!
• Deep Keratitis
-affects the deep layers of the eye
-will be scarring after healed

10. TREATMENTS INCLUDE
• A Topical steriods applied to the eye.
 Tobramycin: one drop every hour
alternating with cefazolin:every hour
• Other Antibiotic drops
• Severe cases might need to be treated with
corneal implants or removal of the cornea all
together!
