Dr. Adriana Valdés Explains Strabismus in Interview with TV Azteca Baja California

Dr. Adriana Valdés, Head of the Pediatric Ophtalmology Service at CODET Vision Institute, recently appeared on Hechos Baja California on TV Azteca to shed light on strabismus—its causes, warning signs in children, and why early diagnosis is essential for long-term eye health.

What is Strabismus?

Strabismus is a condition where the eyes are misaligned and do not work together in perfect coordination. One or both eyes may turn inward (esotropia), outward (exotropia), upward (hypertropia), or downward (hypotropia). While it may appear to be only a cosmetic issue, strabismus can significantly affect vision if left untreated.

What causes Strabismus?

Dr. Valdés explained that strabismus falls into two primary categories: congenital (present at birth) and acquired (develops later in life).

Congenital Strabismus

This form of strabismus often results from improper development during pregnancy. Factors such as nerve or muscle abnormalities, premature birth, oxygen deprivation at birth, or complications during delivery can contribute to its onset.

Many parents first notice only the misalignment, unaware that an underlying eye condition may be responsible. Additional risk factors include uncorrected refractive errors (which may require glasses) and excessive screen time, particularly in adolescents.

A common concern among parents is the natural wandering eye movements of newborns. Dr. Valdés reassured viewers that mild eye drifting is normal in the first four months of life. However, if misalignment persists beyond this period, a specialist should evaluate the child.

Acquired Strabismus

Acquired strabismus develops later in life, sometimes due to an undiagnosed eye condition such as cataracts, which can cause one eye to drift. Other contributing factors include uncorrected vision problems and excessive screen exposure, which may contribute to eye strain and misalignment.

Why Is Early Treatment Crucial?

Dr. Valdés stressed the importance of early intervention. The brain relies on both eyes working together to create a single, clear image. However, when strabismus is present, the brain may suppress the image from the misaligned eye to avoid confusion, essentially “turning it off.” Over time, this suppression can lead to amblyopia (lazy eye) and permanent vision loss if not treated promptly.

Strabismus is not just an aesthetic concern—it can impact a child’s vision, depth perception, and overall eye health. Dr. Valdés encourages parents to stay alert for early warning signs and seek a professional evaluation if they suspect their child has misaligned eyes. With timely treatment, children can receive the necessary care to preserve and improve their vision, ensuring better long-term eye health.
