Insights

Intraocular pressure (IOP) in premature infants generally decreases in the first month of life. However, even moderately elevated IOP may impact ocular perfusion pressure and contribute to retinopathy of prematurity.

Area of Science:

  • Ophthalmology
  • Neonatology
  • Pediatrics

Background:

  • Premature infants have unique physiological characteristics.
  • Monitoring intraocular pressure (IOP) is crucial in neonatal care.
  • Retinopathy of prematurity (ROP) is a significant concern in preterm infants.

Purpose of the Study:

  • To investigate intraocular pressure (IOP) trends in preterm infants during their first month of life.
  • To establish normative IOP ranges for premature neonates.
  • To explore potential clinical implications of IOP variations in this population.

Main Methods:

  • A cohort of 20 preterm infants (gestational age 26–32 weeks) was studied.
  • Intraocular pressure (IOP) was measured using a hand-held applanation tonometer.
  • Measurements were taken shortly after birth and weekly for the first month.

Main Results:

  • Intraocular pressure (IOP) values ranged from 7.6 to 18.3 mm Hg.
  • A statistically significant decrease in mean IOP was observed, from 13.25+/-2.86 mm Hg to 10.96+/-2.01 mm Hg (P < .001).

Conclusions:

  • While observed IOP values were generally not considered pathologic, a lack of expected IOP decrease may have clinical relevance.
  • Elevated IOP in preterm infants could reduce ocular perfusion pressure, potentially contributing to retinopathy of prematurity.
  • Further investigation is warranted to understand the long-term implications of IOP in preterm neonates.

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...
Increased Intracranial Pressure l: Introduction01:14

Increased Intracranial Pressure l: Introduction

Intracranial hypertension is a sustained elevation of intracranial pressure (ICP) above 22 mm Hg. In supine adults, normal ICP is ~7–15 mm Hg.The rigid, nonexpandable cranium contains three components—brain tissue, blood, and cerebrospinal fluid (CSF)—that total ~1,700 mL in a typical adult: 1,400 mL brain (~80%), 150 mL blood (~10%), and 150 mL CSF (~10%). According to the Monro–Kellie doctrine, total intracranial volume is effectively fixed. When one component expands, CSF and venous blood...
Increased Intracranial Pressure ll: Pathophysiology01:29

Increased Intracranial Pressure ll: Pathophysiology

Increased intracranial pressure (ICP) refers to a potentially life-threatening rise in pressure inside the skull. This usually happens when there is a major change in the volume of brain tissue, blood, or cerebrospinal fluid (CSF) — the three components inside the skull. According to the Monro-Kellie doctrine, if the volume of one component increases, the volumes of the other components must decrease to maintain normal pressure. If this does not happen, ICP rises.The process often begins with...
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...
Vision During Infancy and Toddlerhood01:23

Vision During Infancy and Toddlerhood

At birth, vision is the least developed of the major senses because the visual system is still structurally and neurologically immature. The retinas, optic nerves, and visual regions of the brain continue to mature after birth. As a result, newborns have limited visual acuity, or sharpness and clarity of vision, and respond best to objects viewed at close range, roughly 8 to 12 inches away.Rapid Visual DevelopmentVision improves rapidly during the first few months as infants observe and...
Angle Closure Glaucoma: Treatment01:28

Angle Closure Glaucoma: Treatment

Angle-closure glaucoma, or closed-angle glaucoma, is an eye condition where the iris bulges out and blocks the iridocorneal angle, resulting in a buildup of aqueous humor and increased intraocular pressure. Immediate medical attention is necessary due to the sudden onset of symptoms. The treatment for angle-closure glaucoma includes short-term and long-term approaches. Short-term treatment involves using eye drops like pilocarpine to lower intraocular pressure by increasing aqueous humor...
