Photoreceptors and Visual Pathways01:22

Photoreceptors and Visual Pathways

8.1K
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,...

Glaucoma: Overview01:25

Glaucoma: Overview

1.1K
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...

Angle Closure Glaucoma: Treatment01:28

Angle Closure Glaucoma: Treatment

961
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...

Open Angle Glaucoma: Treatment01:27

Open Angle Glaucoma: Treatment

838
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...

Myasthenia Gravis: Overview and Treatment01:20

Myasthenia Gravis: Overview and Treatment

2.4K
Myasthenia gravis is a neuromuscular transmission disorder characterized by weakness and increased fatigability of skeletal muscles. It is an autoimmune disease affecting approximately one in 2000 people, where antibodies against the α1 subunit of nicotinic acetylcholine receptors are produced.
These antibodies interfere with the function of the nicotinic receptors in three ways: by binding to the receptor and disrupting acetylcholine binding; by causing cross-linking of receptors which...

Disorders of the Skeletal Muscle01:28

Disorders of the Skeletal Muscle

1.5K
The clinical conditions affecting the skeletal muscle tissue are broadly categorized as musculoskeletal and neuromuscular disorders.
Musculoskeletal disorders
Musculoskeletal disorders involve injuries and conditions affecting the skeletal muscles and associated connective tissues. These disorders can arise from acute biomechanical stresses or chronic overuse and can occur across different age groups. Common injuries include sprains, fractures, and muscular strains, often resulting from...

  • Neurology
  • Autoimmune Disorders

Background:

  • Neuromyelitis Optica Spectrum Disorders (NMOSD) classification has evolved significantly.

  • To discuss current therapeutic challenges and advancements.

Main Methods:

  • Review of recent literature on NMOSD diagnosis and classification.
  • Analysis of clinical and radiological features differentiating AQP4-IgG and MOG-IgG NMOSD.
  • Evaluation of current and emerging therapeutic strategies.

Main Results:

  • NMOSD is now understood to encompass distinct AQP4-IgG (immune astrocytopathy) and MOG-IgG (myelin-targeting) syndromes.
  • Revised diagnostic criteria incorporate broader clinical features, enabling earlier diagnosis.
  • Newer therapies are available for AQP4-IgG NMOSD, but treatment options for MOG-IgG NMOSD remain limited.

Conclusions:

  • The updated understanding and diagnostic criteria for NMOSD facilitate earlier intervention.
  • Distinguishing between AQP4-IgG and MOG-IgG NMOSD is essential for targeted treatment.
  • Further research is needed to address treatment challenges in MOG-IgG associated NMOSD.
