Eye Problems

Eye issues can go from "minor irritation" to "vision-threatening" quickly, so the most useful owner skill is recognizing which signs are emergencies. AKC notes that cloudy eyes can be a normal aging change (nuclear sclerosis), but cloudiness can also be caused by conditions that require immediate veterinary attention.

Most common patterns owners notice:

- Cloudy lens: nuclear sclerosis vs cataracts (both can look "cloudy," but differ on exam)

- Cloudy surface + pain: corneal ulcers (often squinting, rubbing, discharge)

- Dry, dull eye + thick discharge: keratoconjunctivitis sicca (KCS / dry eye)

Corneal Ulcers - Urgent Signs:

VCA explains that corneal ulcers are painful; dogs often keep the eye tightly closed, rub at it, and the cornea may look cloudy due to fluid in the corneal stroma. Common symptoms include:

- Squinting hard or holding eye shut

- Pawing/rubbing at the eye nonstop

- Cloudy corneal surface

- Eye discharge (clear to mucoid)

- Visible redness or blood vessels in white of eye

Dry Eye (KCS) - Chronic Signs:

Cornell describes KCS as inadequate tear production causing:

- Thick, ropy eye discharge (often yellow or green)

- Dull, dry-looking eye surface

- Recurring eye infections

- Squinting or discomfort

- Red, inflamed conjunctiva

Nuclear Sclerosis vs Cataracts:

AKC notes both cause cloudy appearance but:

- Nuclear sclerosis: bluish haze, usually doesn't significantly impair vision

- Cataracts: white/opaque lens, can progress to blindness

What a good clinic visit usually includes:

1. Complete Eye Examination

- Pupil response testing

- Corneal clarity assessment

- Discharge evaluation

- Redness and inflammation check

- Eyelid and surrounding tissue inspection

2. Fluorescein Stain Test (if ulcer suspected)

- VCA describes fluorescein stain turning ulcerated areas green

- Quick, non-invasive diagnostic

- Essential for confirming corneal ulcers

- Cost in Thailand: 300-800 THB

3. Schirmer Tear Test (if dry eye suspected)

- Measures tear production

- Helps diagnose KCS

- Cornell notes most dogs with KCS need this test

- Cost in Thailand: 400-1,000 THB

4. Specialist Referral (for complex cases)

- Veterinary ophthalmologist consultation

- Advanced imaging if needed

- Available at university hospitals and specialty centers in Bangkok

Corneal Ulcer Treatment:

VCA notes ulcers can worsen and may threaten vision; rechecks are recommended to confirm healing.

- Antibiotic eye drops (prevent infection)

- Pain medication (oral or topical)

- E-collar to prevent rubbing

- Recheck exams (often 3-7 days)

- Cost: 1,500-5,000 THB for initial treatment + rechecks

Dry Eye (KCS) Treatment:

Cornell states most dogs respond to treatment, but KCS often needs lifelong management.

- Cyclosporine or tacrolimus eye drops (stimulate tear production)

- Artificial tears (supplement moisture)

- Treatment of secondary infections

- Regular monitoring (tear production tests)

- Monthly cost: 1,200-3,000 THB for medications

- Recheck visits: 800-1,500 THB every 1-3 months

Cataract Management:

- Medical management for early cases

- Surgical removal (phacoemulsification) for advanced cases

- Referral to veterinary ophthalmologist

- Surgery cost: 40,000-80,000 THB per eye at specialty centers

General Eye Health:

- Regular grooming to keep hair out of eyes

- Clean eye area gently with damp cloth

- Avoid irritants (smoke, harsh chemicals)

- Monitor for early signs of discharge or redness

Breed-Specific Considerations:

- Brachycephalic breeds (Pugs, Shih Tzus): more prone to corneal ulcers

- Small breeds: higher risk of dry eye

- Large breeds: watch for eyelid problems

Environmental Protection in Thailand:

- Limit outdoor time during high pollution days

- Rinse eyes if exposed to dust/sand

- Monitor for tick-borne diseases that can affect eyes
