Accessory Structures of the Eye01:17

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...
Muscles of the Eye01:20

Muscles of the Eye

The muscles of the eye are sophisticated structures that control eye movement and focus, allowing for the precise and rapid adjustments necessary for vision. The human eye is controlled by ten muscles — six extraocular muscles, three intraocular muscles, and one primary eyelid retractor muscle.
Extraocular Muscles
The six extraocular muscles surround the eyeball and control its movements. They are responsible for a wide range of eye motions, including looking up, down, left, right, and rotating...

Summary
This summary is machine-generated.

Neurometry revealed significant brain alterations in children with essential strabismus, indicating functional changes in white matter pathways. These findings suggest a potential link between these neurometric changes and the underlying causes of strabismus.

Area of Science:

  • Neuroscience
  • Ophthalmology
  • Biomedical Engineering

Background:

  • Neurometry quantifies cerebral bioelectrical activity via digital cerebral mapping.
  • It assesses white matter tract efficiency using coherence analysis.
  • Essential strabismus is a condition affecting eye alignment.

Purpose of the Study:

  • To investigate neurometric alterations in the cerebral cortex of individuals with essential strabismus.
  • To correlate these brain activity changes with the pathophysiology of strabismus.

Main Methods:

  • A cross-sectional, descriptive, observational study.
  • Neurometric analysis of 23 electroencephalogram (EEG) parameters in 16 children with essential strabismus.
  • Comparison of results with international NeuroGuide standards.

Main Results:

  • All analyzed cases showed neurometric alterations.
  • Key findings include intertemporal hypocoherence and increased slow waves.
  • Decreased temporal lobe frequency, increased occipital lobe symmetry, and frontal lobe power decline/asymmetry were observed.

Conclusions:

  • Strabismus patients exhibit altered cortico-cortical, cortico-subcortical, and interhemispheric pathways.
  • These alterations suggest functional white matter changes.
  • These changes may play a role in the pathophysiogenesis of essential strabismus.
