Insights

This study established normal intraocular pressure (IOP) ranges for school-aged children using the Icare tonometer. Males showed higher IOP and a correlation with age, unlike females.

Area of Science:

  • Ophthalmology
  • Pediatric Optometry
  • Ocular Biomechanics

Background:

  • Intraocular pressure (IOP) is a critical factor in ocular health.
  • Normative data for IOP in healthy school-aged children are limited.
  • Understanding typical IOP ranges is essential for early detection of potential vision abnormalities.

Purpose of the Study:

  • To establish mean and normal ranges of intraocular pressure (IOP) in healthy school-aged children using the Icare rebound tonometer.
  • To investigate potential associations between IOP and various visual function measures in this demographic.

Main Methods:

  • IOP was measured using the Icare tonometer in 211 children (aged 6-15 years).
  • Six IOP measurements were taken from each eye.
  • Visual acuity, retinoscopy, amplitude of accommodation, accommodative facility, and accommodative response were also assessed.

Main Results:

  • Males exhibited higher mean IOP (15.02 mm Hg) compared to females (14.44 mm Hg) (P=0.041).
  • A significant association between age and IOP was observed in males (P<0.001), but not in females (P=0.459).
  • IOP showed significant associations with the amplitude of accommodation in males, particularly up to age 11.

Conclusions:

  • This study provides valuable normative intraocular pressure (IOP) data for European school-aged children utilizing the Icare tonometer.
  • The findings highlight potential sex-based differences in IOP and its correlation with age and accommodation in children.

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.
Drugs such as carbonic anhydrase inhibitors, α2- and...

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...
