Accessory Structures of the Eye01:17

Accessory Structures of the Eye

4.3K
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...

Photoreceptors and Visual Pathways01:22

Photoreceptors and Visual Pathways

10.9K
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,...

Equilibrium and Balance

7.9K
The inner ear assumes dual functionalities of auditory perception and equilibrium maintenance. The vestibule is the organ responsible for balance. This organ contains mechanoreceptors, specifically hair cells, endowed with stereocilia, which aid in deciphering information regarding the position and motion of our heads. Two intrinsic components, the utricle and saccule, help perceive head position, while the semicircular canals track head movement. Neurological messages initiated in the...

Glaucoma: Overview01:25

Glaucoma: Overview

1.6K
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...

Muscles of the Eye01:20

Muscles of the Eye

5.5K
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...

Positive Symptoms of Schizophrenia: Hallucinations and Delusions01:30

Positive Symptoms of Schizophrenia: Hallucinations and Delusions

1.0K
Schizophrenia is a complex mental health disorder that can manifest with various positive symptoms, including thought, movement, and behavior disorders. These symptoms significantly disrupt cognitive and motor functions, leading to profound effects on an individual's ability to engage with the world.
Thought Disorders
Disorganized and unusual thought processes mark thought disorders in schizophrenia. One key feature is disorganized speech, where an individual's conversation includes...

Summary

Psychogenic ophthalmologic movement disorders (POMDs) occurred in 6% of patients with psychogenic movement disorders (PMDs). While psychotherapy improved some POMD cases, others persisted, highlighting POMDs

Area of Science:

  • Neurology
  • Ophthalmology
  • Psychiatry

Background:

  • Psychogenic movement disorders (PMDs) encompass a range of functional neurological symptoms.
  • Psychogenic ophthalmologic movement disorders (POMDs) represent a specific subtype affecting ocular motor control.
  • Understanding the prevalence and characteristics of POMDs is crucial for comprehensive patient management.

Purpose of the Study:

  • To determine the prevalence of POMDs within a cohort of PMD patients.
  • To describe the clinical phenomenology and demographic features of POMDs.
  • To evaluate treatment outcomes for patients with POMDs.

Main Methods:

  • Retrospective identification of 11 patients with POMDs from 182 PMD patients.
  • Review of medical charts and video recordings for diagnostic confirmation and phenomenological analysis.
  • Statistical comparison of demographic and clinical data between patients with and without POMDs.

Main Results:

  • POMDs were identified in 11 patients (6%) within the PMD cohort.
  • Common POMD presentations included oculogyric crises, opsoclonus, and ocular flutter.
  • A trend towards younger age at onset was noted in patients with POMDs compared to those without.

Conclusions:

  • POMDs are a relevant, albeit less common, manifestation within the spectrum of PMDs.
  • Psychotherapy demonstrated efficacy in a subset of POMD patients.
  • Persistent symptoms in some cases underscore the complexity of POMD management and contribute to overall patient morbidity.
