Insights

Accelerated growth in the first year of life is linked to poorer visual acuity and refractive outcomes in high-risk infants. This highlights the critical importance of early systemic growth for infant eye development.

Area of Science:

  • Pediatric Ophthalmology
  • Developmental Pediatrics
  • Growth Monitoring

Background:

  • High-risk infants often exhibit atypical growth patterns and are susceptible to visual impairments.
  • Limited evidence exists linking early systemic growth trajectories with ocular development in this vulnerable population.

Purpose of the Study:

  • To investigate the association between growth trajectories from birth to 3 years and ocular development in high-risk infants.
  • To identify critical periods of growth influencing visual acuity and refractive status.

Main Methods:

  • A population-based prospective study of 10,030 high-risk infants.
  • Repeated measurements of weight, length, BMI, and head circumference from birth to 36 months.
  • Calculation of growth velocities and assessment of uncorrected visual acuity (UCVA) and cycloplegic spherical equivalent refraction (SER) at 3-4 years.

Main Results:

  • Poorer UCVA was observed in preterm and term low-birth-weight infants compared to macrosomic infants.
  • Preterm infants had the most hyperopic SER, while macrosomic infants had the least.
  • Accelerated growth between 0-12 months was consistently associated with poorer UCVA and more hyperopic SER.

Conclusions:

  • Accelerated early-life growth, particularly within the first year, is associated with less favorable visual and refractive outcomes in high-risk infants.
  • The first postnatal year represents a critical window for coordinated systemic and ocular development.

Accessory Structures of the Eye

Optical perception, or vision, is an extraordinary sense dependent on converting light signals received via the ocular organs. These organs, known as eyes, are securely positioned within the bony cavities of the skull, called orbits. The orbits serve a dual purpose: a protective shield for the ocular globes and a stable attachment point for the soft ocular tissues. The eye's external protective mechanisms include the eyelids, which are edged with lashes that act as a barrier against foreign...

Glaucoma: Overview01:25

Glaucoma: Overview

Glaucoma is an eye condition characterized by increased intraocular pressure that damages the retina and optic nerve, leading to irreversible blindness if left untreated. The human eye has various components, including the cornea, iris, pupil, lens, and optic nerve. Aqueous humor is secreted by the epithelium of the ciliary body in the posterior chamber and flows through the trabecular meshwork and canal of Schlemm, maintaining normal intraocular pressure. The trabecular meshwork and the canal...

Open Angle Glaucoma: Treatment01:27

Open Angle Glaucoma: Treatment

In open-angle glaucoma, the iridocorneal angle remains open, but the trabecular meshwork becomes stiff, slowing down the outflow of aqueous humor. This causes a buildup of aqueous humor in the anterior chamber, leading to a sudden increase in intraocular pressure. The treatment for open-angle glaucoma focuses on reducing the elevated intraocular pressure by either decreasing the secretion of aqueous humor or increasing its outflow.
