"He was trying to catch the beetle, a big one. The beetle must have bitten him!  He has not been eating for a few days and has lost a lot of weight. His right eye is much swollen!"

You rarely encounter beetles in Singapore  apartments nowadays and cats will have to content with lizards and some cockroaches. The conjunctiva was so enlarged that the iris could not be seen.  Fortunately, the eyeball was intact. But for how long?

An antibiotic injection was necessary. Antibiotics eye drops were given and an Elizabeth collar was worn. This was not a simple case of eye infection. The cat had a high fever and was not eating.  You could see a long scratch laceration wound parallel to the eyelid. This beetle must have been fierce and dug into the eyelid introducing the pus forming bacterial germs. Antibiotics and fluid therapy by injection were given on the first day.

A thick brown exudate glued the eyelid shut the next day.  The cat was resisting and clawing when I wanted to open its upper and lower eyelids to clean up the pus forming bacterial infections. 

Permission from the Owner to tranquilise the cat to do the job was required as the cat may just die after tranquilization, being in a weak state.  Shiny yellow pus oozed out of the eyelid the second day.  On day 4, the eye was free of pus and the cat went home to be hand-fed and given eye drops.  He would have used up one of his nine lives as the bacteria had spread to his blood stream and caused a high fever. 

Dried pus glued eyelids tightly. Needs human intervention to remove the exudate. Elizabeth collar important to prevent further eye scratching.
Use one hand to lift the cat's chin and the other for eye-drops. I lifted the cat's chin with one hand and quickly put in 10 eye drops with the other hand. The affected area was really a big wound after the hair was clipped and shaved. The Beetle's mouthparts might have sunken into the conjunctiva (the swollen fleshy tissue below the upper eyelid).  The cat had tranquilisation in this case.  

He had an Owner who had sought veterinary treatment quite early, otherwise he would have lost his eye to severe infection and would have died of sepsis. Many of these eye infection cases need prompt treatment and long nursing after leaving the veterinary clinic. 

Left untreated, the cat would have scratched his eye persistently till the eyeball gets ruptured. The pus would get into the eyeball via the corneal ulcerations and the eyeball   would have collapsed in due course.

It would be extremely painful and if the cat survived, it would have a sunken eyeball and be blind for the rest of his life.  This cat is fortunate since his owner has sought veterinary treatment early enough and saved his precious eyesight to hunt another day.

The cat has the similar coat colour as the 2010 case below. Without this search engine, it would be difficult for me to fish out this case. It was written one decade ago. My digital images were really the types to be thrown into the garbage bin but then you must start your project and learn from doing and failing. Failures will occur in your life time and hopefully, you will succeed (in producing beautiful digital images) one day.

Self-inflicted corneal ulcers are seen under the fluorescein eye stain tests. The fluorescein crops are orange in colour but it stains the ulcers green.

The distribution of the green areas will reveal the extent of corneal abrasions and ulcerations and this "show and tell" convince the owners of the severity or otherwise of their pet's eye injuries. Evidence-based practice is good practice. Serious extensive corneal ulcerations need surgery rather than just some eye drops as healing of the cornea will usually not occur if the ulcers are extensive and exposed to sunlight and breezes 
2010 CASE: THE CAT HAS A TEARING EYE FOR THE PAST TWO WEEKS

A bright sunshine morning made me feel that I should be outdoors on this August 1, 2010 Sunday. But I had my duties. Below is an interesting cat case. Interesting to vet students I hope. 

The cat had tearing of the left eye for the past two weeks. There is another cat at home. "Probably the other cat has scratched his eye," the young lady said. "The tearing stopped a while and came back again."

I noted that both ears were full of wet ear wax. "I clean the ears but the dirt comes back," the young lady told me. "But the other cat has such clean ears."

So, there was a problem. How to resolve the cat's ear and left eye problem? Go back to basics and an understanding of the cat's grooming behaviour. The treatment plan is given below and in visual means as I know the young ones just don't have time or interest to read grandmother's stories.

Dogs and cats with eye discharge for 2 weeks may have foreign bodies embedded inside the eye conjunctiva or inside the 3rd eyelid. As the animal cannot get rid of the foreign bodies, it must be sedated and the 3rd eyelid and conjunctiva checked for embedded foreign bodies. They are irrigated with water to flush away the dirt. Sometimes, the dirt comes from the ear infected wax and debris.

Therefore, it is not just a simple case of giving some medication and eye-drops as further scratching may cause eye corneal ulcerations and an infected inner eye, leading to loss of vision and eye.  Sometimes, vets are so busy and do overlook that epiphora over 1 week's duration does need more detailed examination and treatment under anaesthesia to save the poor animal's eyesight and relieve the pain.
