Insights

Very low birth-weight infants with severe intraventricular hemorrhage face higher risks of developing esotropia and optic atrophy. Early ophthalmologic screening is crucial for timely diagnosis and intervention in these vulnerable infants.

Area of Science:

  • Neonatal ophthalmology
  • Pediatric neurology
  • Perinatal medicine

Background:

  • Intraventricular hemorrhage (IVH) is a significant complication in very low birth-weight (VLBW) infants.
  • Neurologic morbidity associated with IVH can lead to various ocular complications.
  • Ocular outcomes in VLBW infants with IVH require further investigation.

Purpose of the Study:

  • To document ocular outcomes in VLBW infants with intraventricular hemorrhage.
  • To determine the prevalence of ocular diseases in this high-risk population.
  • To identify risk factors for specific ocular conditions.

Main Methods:

  • Retrospective review of VLBW infants (<= 1,500 g) admitted to the NICU.
  • Complete ophthalmologic examinations performed at a mean adjusted age of 11 months.
  • Statistical analysis (Chi-square, multivariate) controlling for confounding factors.

Main Results:

  • Strabismus occurred in 37% of infants with IVH; esotropia in 32%.
  • Severe IVH (grades III-IV) significantly increased the risk of esotropia (OR, 5.0; P = .04).
  • Periventricular leukomalacia and neonatal seizures were linked to increased risk of optic atrophy.

Conclusions:

  • VLBW infants with severe neurologic compromise from IVH are at high risk for esotropia and optic atrophy.
  • Ophthalmologic screening for all VLBW survivors can facilitate early detection and management.
  • Prompt intervention may improve visual outcomes in at-risk infants.

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...
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...
Photoreceptors and Visual Pathways01:22

Photoreceptors and Visual Pathways

At the molecular level, visual signals trigger transformations in photopigment molecules, resulting in changes in the photoreceptor cell's membrane potential. The photon's energy level is denoted by its wavelength, with each specific wavelength of visible light associated with a distinct color. The spectral range of visible light, classified as electromagnetic radiation, spans from 380 to 720 nm. Electromagnetic radiation wavelengths exceeding 720 nm fall under the infrared category, whereas...
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...
