Pediatric Eye Exams
Ensuring your children have good vision is crucial for comfortable learning. Vision problems that might require an eye doctor for children, can affect reading and attention, but screening and correcting these issues early can significantly improve school performance. Eye exams can start as early as 6 months, with the first recommended at age 1 if no immediate concerns arise.
Common Pediatric Ocular Conditions
Hyperopia
The most common issue in children is hyperopia, often known as far-sightedness. It means seeing clearly at a distance but struggling with close-up vision.
Hyperopia treatment depends on its severity, some kids may not need glasses. Yet, if it's severe, it can impact both near and distant vision. Correcting significant far-sightedness with reading glasses can enhance a child's reading comfort.
Exophoria/Esophoria
Exophoria and Esophoria correspond to the binocularity of your child's eyes. All individuals have small variances in the alignment of their eyes. If the eyes are more outwards aligned, it is termed exophoria, and naturally inwards alignment is termed esophoria.
Orthophoria would refer to an alignment that is straight. Many phorias are present in small amounts and do not require any treatment. If the magnitude of a phoria is high however, it can cause significant discomfort while reading or early fatigue when reading. Treatment of high phorias is usually done with prism in glasses or vision therapy.
Convergence Insufficiency
Convergence insufficiency (CI) is a common vision issue in children, affecting their ability to focus on near objects. It involves problems with eye muscle coordination, specifically the movements known as versions (eye movements in the same direction) and vergences (eye movements in opposite directions).
CI is characterized by a difficulty in converging the eyes inward when focusing on close objects. Vision therapy is often used as a treatment for this condition.
While there are other categories like convergence excess, divergence insufficiency, and divergence excess, they are less common and have a milder impact on school performance compared to CI.
Strabismus
Strabismus, a condition where one eye is misaligned differently from the other, can be categorized as exotropia or esotropia depending on the direction of misalignment.
Factors such as laterality (right, left, or alternating eye involvement), frequency (intermittent or constant misalignment), direction (outward or inward), and magnitude (measured in prism diopters) play a crucial role in determining the most appropriate treatment. Typically, vision therapy is the primary approach for treating strabismus.
Amblyopia
Amblyopia, commonly known as "lazy eye," is a sensory condition that impairs the connection between one eye and the brain's interpretation center, leading to reduced vision in that eye. Unlike vision problems corrected by glasses or surgery, amblyopia requires a different approach. Improving vision involves a combination of precise prescription, patching therapy, and vision therapy to enhance communication with the affected eye.
​
Amblyopia risk factors are categorized into Refractive Amblyopia, resulting from significant prescription differences between the eyes, and Strabismic Amblyopia, caused by misaligned eyes reducing clear vision exposure.
​
Early detection of amblyopia or amblyogenic factors in childhood is crucial for effective treatment. Regular eye exams during youth can address vision issues promptly or prevent the development of a lazy eye. Children respond better to treatment due to their brain's higher plasticity, while adults can still benefit from intervention, albeit with slightly reduced potential for improvement.
