02How can I assess the situation at home? Key observations and emergency criteria
Key observations to make at home before the vet visit — these details help your veterinarian assess the condition and plan the appropriate examination quickly.
- Note the first time you noticed the issue and how symptoms have changed over time
- Take close-up photos and short videos of the eye from both sides using your phone
- Observe the color, amount, consistency, and any odor of the discharge
- Check whether the condition is affecting vision, eye closure, or causing light avoidance
- Record any changes in appetite, water intake, or toileting habits
- If there is pain or a visible pain response when touched, note when it occurs
- Consider booking an appointment at a clinic with ophthalmology capabilities
03How will the vet make a diagnosis? Common examination steps
Common diagnostic steps performed at the clinic to assess ocular tissue and rule out other underlying causes.
Full physical examination combined with specialist ophthalmology assessment (slit-lamp, eyelid examination)
Sampling of ocular discharge for microscopy or culture
Corneal staining to evaluate for ulceration or surface damage
Blood and biochemistry panel to assess overall health and infection risk
X-ray, ultrasound, or head imaging to evaluate surrounding structures if indicated
Referral to a veterinary ophthalmologist for complex or advanced cases
04What are the treatment and care options? Medications, adjustments & home care guide
Treatment is tailored to the individual case. Post-surgical follow-up, medication compliance, and attentive home care are all important parts of recovery.
- Topical medications to manage inflammation or infection, to be used strictly as directed by your vet
- Some cases require surgical repositioning or repair — this is determined after specialist evaluation
- Regular follow-up visits after surgery to confirm gland repositioning and wound healing
- Home care focuses on preventing rubbing or pawing and keeping the area around the eye clean
