Canine Conjunctivitis
- Most commonly this is bacterial conjunctivitis
- Check for a predisposing cause
– Always do a STT in all cases of conjunctivitis (and
corneal disease and ocular discharge)
– Check under the third eyelid and the eyelids
- Grass seeds
- Tumours
Animal Eye Carep.5 -
p.6
Canine Conjunctivitis
- Topical Antibiotics
– Tricin – triple antibiotics, if red or inflamed Amacin
– Use TID for 5 days
– Check then recheck the STT – tear test

Recurrent Canine Conjunctivitis
- Usually there is an underlying cause eg dry eye or a FB
- IF no underlying cause the recurrent cases are usually allergic
- Topical cortisone drops are indicated
– Topical cyclosporin/Tacrolimus may helpAnimal Eye Care

Feline Conjunctivitis
- Usually infectious
- Oral Doxycycline 5mg/kg BID for 21 days
- Hylo-Forte – 1 drop BID to TID
- Most cases settle down well
- If redness persists then topical NSAIDs may be needed.Animal Eye Care

- Is it dry eye ? – Always do a STT – Schirmer Tear Test
- Allergic
Animal Eye Carep.17 -
p.18
Feline Conjunctivitis Summary
- Cats
– Usually due to Herpes and or Chlamydia
– Most cases require a prolonged course of oral doxycycline 5mg/kg BID for 21 days
– Hyaluronate tears eg Hylo-Forte BID
Animal Eye Carep.18 -
p.19
Squinting
- Can be caused by
– Eyelid disease eg entropion, extra eyelashes
– Corneal Ulceration
– Ocular pain
- Uveitis
- Glaucoma
– Treat the underlying cause

Managing Ocular Pain
- Tramadol
- Gabapentin

Ocular Discharge - watery
Animal Eye Carep.23 -
p.24
Watery Ocular Discharge
- Do a STT – Schirmer tear test
– >20 mm wetting suggests irritation that might be
causing the epiphora
– Normal STT~ 15 mm suggests decreased nasolacrimal fluroscein passage
Animal Eye Carep.24 -
p.25
Watery Ocular Discharge - epiphora
- Nasolacrimal fluroscein passage
– No passage through to the nose indicates its time to flush the tear duct

Mucky Ocular Discharge
- Dry eye
- Dry eye
- Dry eye
- Chronic Conjunctivitis
- Nasolacrimal duct infection
– Dacryocystitis
• Foreign bodies
Animal Eye Carep.27 -
p.28
• Do a STT – mm wetting/minute cause
- If normal think of reduced nasolacrimal drainage
-If no nasolacrimal fluorescein passage time to flush the tear duct
– If > 20 think irritation as a
– If < 15 think dry eye

Dry Eye – keratoconjunctivitis sicca
- Always do a STT – s¥Schirmer tear test in all cases of conjunctivitis, corneal disease and all cases of ocular disease
- Dry eye can be the cause or as the result of conjunctivitis

Dry Eye
- Breed predisposition
- Best results with treatment when
– Initial STT > 5mm
– Been less than 6 months
- Always do a STT
Animal Eye Carep.32 -
p.33
Dry eye treatment
- Artificial Tears
– Preservative free Systane UD or Hylo-Forte
- Clean the eyes clear of all discharge before applying the active drugs
– Mucous can stop the active drugs from getting to the lacrimal glands
Animal Eye Carep.33 -
p.34
Dry Eye
- Artificial Tears
– 1-2 drops to clean out all the mucous
- Optimmune – Cyclosporin Ointment
– Most cases BID
– Severe cases TID
- Cortisone ointment if the cornea is healthy enough eg Siguent Hycor
Animal Eye Carep.34 -
p.35
Dry Eye Summary
- Always do a STT – early treatment gives the best results
- Optimmune BID, if STT<6 mm use TID
- Wipe away all the mucous
– Long term treatment likely
- Tacrolimus if the response is poor

p.36
Corneal Ulceration
- Always do a STT in all cases of ulcers
- Look for a cause

p.37
Corneal Ulceration
- Look for a cause

p.38
Corneal Ulcer Treatment
