What It Is
Microphthalmia is a congenital ocular developmental abnormality in which one or both globes are abnormally small, often with associated structural eye defects and variable visual impairment.
Also Called: small eye; congenital small globe
Breeds Affected: American Akita; Portuguese Water Dog
The Idiot-Proof Explanation
The eye did not develop to normal size. Sometimes the dog can see a little. Sometimes the eye is mostly decorative. Sometimes the small eye comes with extra problems inside it, because apparently one defect was not enough paperwork.
What Causes It
Microphthalmia happens during fetal eye development. The globe forms smaller than normal, and other eye structures may also develop abnormally.
Causes may be genetic, developmental, or associated with broader congenital eye defects. Severity depends on whether one or both eyes are affected and what other structures are abnormal.
- The condition is present at birth, even if it is noticed later.
- One eye or both eyes may be affected.
- Vision can range from mildly reduced to absent.
- Associated defects may include cataracts, retinal issues, coloboma, or glaucoma risk depending on the case.
Bottom line: a small eye is not just a cosmetic quirk. It needs an actual eye exam so everyone knows what function and risks are attached to it.
What This Means for Life With This Dog
Life with microphthalmia depends on vision and comfort. A stable, comfortable, nonvisual eye may need monitoring. A painful or complicated eye can become a medical problem.
Owners need to know whether the dog sees, whether the eye is comfortable, and whether pressure, ulcers, inflammation, or other defects are part of the deal. Guessing by how cute the face is remains a bad diagnostic method.
Dogs with one good eye can often live very normal lives, but owners need to protect the functional eye like it is the last good phone charger in the house.
Can It Be Fixed?
The small globe cannot be made normal. Treatment is based on comfort, vision, and complications. Monitoring may be enough in mild cases, while painful or diseased eyes may need medication or removal.
Symptoms Owners May Notice
One or both eyes look small: The affected eye may sit differently, look underdeveloped, or be noticeably smaller than the other eye.
Vision problems: The dog may bump into things, startle on one side, hesitate in dim light, or rely more heavily on the better eye.
Squinting, redness, or cloudiness: These signs can mean discomfort, inflammation, corneal issues, glaucoma, or other complications that need a vet instead of a shrug.
Abnormal pupil or eye shape: Some dogs have obvious structural differences, cloudy areas, or pupils that do not look quite right.
Treatment Options
Ophthalmic exam: A full eye exam checks vision, pressure, corneal health, lens, retina, and whether the small eye is comfortable or quietly causing trouble.
Monitoring or medication: Comfortable eyes may only need monitoring. Inflamed, dry, ulcerated, or high-pressure eyes may need medication and follow-up.
Surgery for painful nonfunctional eyes: If the eye is blind and painful, removal may be the kindest option. Cosmetic attachment to a painful eye helps exactly no dog.
Recovery and Aftercare
Aftercare depends on the problem found. It may mean routine monitoring, daily eye medication, pressure checks, protecting the good eye, or post-op care if removal is needed.
What Happens If You Wait
Waiting can turn a weird-looking eye into a painful eye.
If the eye is developing glaucoma, ulcers, inflammation, or chronic irritation, delaying care can cost the dog comfort and possibly the remaining vision it had.
Cost Reality Check
Microphthalmia costs depend on whether the eye is stable or complicated, whether an ophthalmologist is needed, and whether medication or surgery enters the chat.
| Care Level | What It May Include | Estimated Cost |
|---|---|---|
| Initial workup | Exam, eye pressure check, stain test, and basic ophthalmic assessment. | $150-$500 |
| Ongoing management | Ophthalmology referral, repeat monitoring, medication, and diagnostics for associated defects. | $500-$2,000+ |
| Severe case | Surgical management for painful blind eyes, advanced diagnostics, or major complications. | $1,500-$5,000+ |
Comfort level: A comfortable small eye is cheaper than a painful small eye with glaucoma or ulcer drama.
One eye or both: Bilateral disease changes the whole owner-management conversation.
Specialist care: Ophthalmology gives better answers, and better answers often come with specialty pricing.
Surgery need: Medication monitoring and eye removal are very different invoices.

Tell Me What I Should Really Expect
Microphthalmia is only “just cosmetic” after a vet proves the eye is comfortable and stable.
A dog can live well with reduced vision, but pain is not negotiable. Get the eye evaluated, protect the good vision, and do not let a tiny eye become a giant untreated problem.
