Infantile Esotropia

Infantile esotropia is a form of eye misalignment that appears in the first six months of life. In this condition, one or both eyes turn inward toward the nose rather than pointing straight ahead. Unlike other types of crossed-eyes that come and go, infantile esotropia is typically a large, constant turn, often greater than 30 prism diopters in angle, and is not caused by glasses or refractive error alone Wikipediamorancore.utah.edu.

Because the eyes are not lined up correctly, the brain cannot use both eyes together to form a single picture. If left untreated, this can lead to permanent vision loss in the deviated eye (amblyopia) and poor depth perception. Early diagnosis and management—ideally before age two—are crucial to give the child the best chance of developing normal binocular vision WikipediaNCBI.

Infantile esotropia is a form of strabismus in which one or both eyes turn inward intermittently or constantly, usually appearing between birth and six months of age. In simple terms, it means a baby’s eyes do not line up properly and one eye drifts toward the nose. This condition is not caused by glasses needing correction; rather, it stems from how the brain and eye muscles develop and coordinate. Early alignment of the eyes is essential for the brain to learn how to use both eyes together, which is critical for depth perception and normal vision development.

Infantile esotropia typically presents as a large-angle inward turn (often 30–60 prism diopters) and may be associated with normal focusing ability (emmetropia) or mild farsightedness. Parents might notice the turning most when the child is looking at objects nearby, when tired, or when focusing intently on something. If untreated, the brain may suppress the image from the misaligned eye to avoid double vision, leading to amblyopia (“lazy eye”) and poor binocular vision. Early detection and treatment can help prevent these complications and promote healthy visual development.

Types of Infantile Esotropia

Essential Infantile Esotropia
Also called “early-acquired esotropia,” this type develops between birth and six months of age. It is characterized by a stable, large inward turn of the eyes, not linked to glasses or other eye problems. Children often show cross-fixation, using the right eye to look left and the left eye to look right WikipediaNCBI.

Refractive Accommodative Infantile Esotropia
In these cases, high farsightedness (hyperopia) forces the child to focus too hard, causing excessive inward turning. Glasses that correct the farsightedness often fully or partially straighten the eyes, especially when prescribed early and worn consistently NCBI.

Non-Refractive Accommodative Infantile Esotropia
Here, the eye turn is linked to an unusually high convergence response to focusing (high AC/A ratio), rather than uncorrected hyperopia. Glasses help only a little, and surgery is often needed to align the eyes NCBI.

Partially Accommodative Infantile Esotropia
These children have moderate farsightedness. Glasses improve alignment but do not fully correct the inward turn, so surgery is usually planned after initial optical treatment and amblyopia therapy NCBI.

Sensory Infantile Esotropia
When poor vision in one eye (from cataract, retinal disease, or other cause) prevents normal eye teaming, that eye drifts inward permanently. Treating the underlying eye problem and then correcting alignment surgically can help preserve whatever binocular vision remains NCBI.

Consecutive Infantile Esotropia
This develops after surgery for outward-turned eyes (exotropia) if the eyes are over-corrected and turn in too far. Management may involve adjusting or re-operating on the eye muscles NCBI.

Intermittent Infantile Esotropia
Although less common in true infantile cases, some children initially have intermittent crossing that later becomes constant. Early detection during the intermittent phase can prompt vision therapy to slow progression Cleveland Clinic.

Constant Infantile Esotropia
The inward turn remains present at both near and far, in all directions of gaze. This is the classic presentation of essential infantile esotropia, often accompanied by other eye-movement issues like inferior oblique overaction or dissociated vertical deviation Cleveland Clinic.

Pseudoesotropia
Not a true esotropia—infants may appear cross-eyed because of a flat nasal bridge or extra skin folds at the inner eye corners. Corneal light reflex and cover tests show normal alignment, and the apparent deviation usually resolves as facial features mature Cleveland Clinic.

Causes of Infantile Esotropia

1. Family history of strabismus. Genetics play a role—children with relatives who had crossed eyes are more likely to develop the condition Cleveland Clinic.

2. Preterm birth. Babies born early often have immature eye-movement control, increasing risk of misalignment Cleveland Clinic.

3. Maternal alcohol use during pregnancy. Alcohol exposure can affect developing vision centers in the brain, leading to misalignment Cleveland Clinic.

4. Maternal substance use during pregnancy. Certain drugs may disrupt normal nerve and muscle development in the eyes Cleveland Clinic.

5. Genetic variations. Specific genes influencing eye-muscle coordination may be altered, predisposing infants to esotropia Cleveland Clinic.

6. Neurologic disorders. Conditions like cerebral palsy or hydrocephalus can interfere with brain signals that control eye alignment Cleveland Clinic.

7. High farsightedness (hyperopia). Excessive focusing effort causes too much inward turning if uncorrected Cleveland Clinic.

8. Hyperthyroidism. Thyroid eye disease can cause misalignment due to swollen eye muscles Cleveland Clinic.

9. Diabetes. Nerve damage from diabetes can disrupt eye-muscle coordination Cleveland Clinic.

10. Innervational imbalance. An early disturbance in the balance of signals that make eyes converge and diverge leads to a fixed inward turn NCBI.

11. Abnormal accommodation. In some infants, the process of focusing itself triggers excessive eye convergence (accommodative esotropia) NCBI.

12. Uncorrected hypermetropia. Farsightedness left untreated causes over-convergence to keep images clear, worsening the turn NCBI.

13. High AC/A ratio. A high ratio of accommodative convergence to accommodation makes focusing efforts drive the eyes inward too strongly NCBI.

14. Low fusional divergence amplitude. Poor ability to diverge the eyes means they stay crossed once they turn in NCBI.

15. Inferior oblique muscle overaction. An over-strong oblique muscle can pull the eye inward and upward, contributing to esotropia NCBI.

16. Dissociated vertical deviation. A drifting upward of one eye when the other fixes can coexist with esotropia, complicating alignment NCBI.

17. Latent nystagmus. An involuntary shaking movement that appears when one eye is covered can disrupt binocular vision development NCBI.

18. Brain tumor or increased intracranial pressure. Space-occupying lesions can affect the nerves controlling eye movement, causing inward deviation Cleveland Clinic.

19. Eye injury. Trauma to the extraocular muscles or nerves can lead to restrictive or paralytic esotropia Cleveland Clinic.

20. Cataract or optic nerve problems. Early-onset eye disease that impairs vision in one eye can result in that eye wandering inward (sensory esotropia) Cleveland Clinic.

Symptoms of Infantile Esotropia

1. Inward turning of the eye(s). The most obvious sign is one or both eyes consistently pointing toward the nose instead of straight ahead Cleveland Clinic.

2. Eyes that do not move together. When looking side to side or up and down, one eye may lag or overshoot Cleveland Clinic.

3. Squinting or blinking. Babies may narrow their eyes or blink often to try and see more clearly Cleveland Clinic.

4. Tilting or turning the head. To use the straight eye for seeing, an infant may habitually tilt or turn the head Cleveland Clinic.

5. Double vision (diplopia). Older children may report seeing two images of a single object Cleveland Clinic.

6. Eye strain. Over-efforting the eye muscles can lead to tired, sore eyes or rubbing Cleveland Clinic.

7. Poor depth perception. Difficulty judging distances and bumping into objects is common Cleveland Clinic.

8. Amblyopia (lazy eye). When one eye is misaligned, the brain may ignore its input, leading to reduced vision in that eye Cleveland Clinic.

9. Reduced binocular vision. Inability to use both eyes together for 3-D vision Cleveland Clinic.

10. Difficulty focusing. Infants may look past objects or seem uninterested in near toys Cleveland Clinic.

11. Frequent covering of one eye. Older children may cover an eye to avoid double vision Cleveland Clinic.

12. Delayed visual milestones. Lack of eye contact or tracking may be noted in babies Cleveland Clinic.

13. Headaches. Especially in school-age children, eye misalignment can cause headaches from strain Cleveland Clinic.

14. Blinking excessively in bright light. Sensitivity due to poor alignment may cause squinting in sunlight Cleveland Clinic.

15. Social or emotional effects. Older children may avoid eye contact or play due to self-consciousness about their appearance Cleveland Clinic.
