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

981
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

856
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

2.5K
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...

Myasthenia Gravis: Diagnostic Tests

1.7K
Myasthenia gravis is an autoimmune condition affecting neuromuscular transmission, causing generalized weakness in skeletal muscles. Initial diagnoses rely on patients' signs, symptoms, and medical history. The challenge lies in distinguishing myasthenia from other muscular dystrophies. An important diagnostic feature is the significant improvement of symptoms after administering anticholinesterase inhibitors.
The edrophonium test is a diagnostic tool for myasthenia gravis. It involves...

Area of Science:

  • Neuroimmunology
  • Neurology

Background:

  • Neuromyelitis optica (NMO), or Devic syndrome, is a CNS inflammatory demyelinating disease.
  • NMO involves acute optic neuritis and transverse myelitis.
  • NMO is primarily associated with autoantibodies against aquaporin 4 (AQP4-IgG) or myelin oligodendrocyte glycoprotein (MOG-IgG).

Purpose of the Study:

  • To review the current understanding of NMO pathogenesis.
  • To discuss recent advancements in NMO treatment and management.
  • To highlight the approval of new therapies for AQP4-IgG positive NMO.

Main Methods:

  • Review of recent clinical trials and literature on NMO.
  • Analysis of therapeutic monoclonal antibodies for NMO treatment.
  • Discussion of improved long-term outcomes with current treatments.

Main Results:

  • NMO treatments, including immunosuppressants and B cell-depleting agents, have significantly improved patient outcomes.
  • New therapeutic monoclonal antibodies have been approved for AQP4-IgG positive NMO.
  • Understanding of NMO pathogenesis has advanced, identifying key autoantibodies.

Conclusions:

  • NMO management has evolved, with improved prognoses due to targeted therapies.
  • The development of specific treatments for AQP4-IgG positive NMO marks a significant therapeutic advance.
  • Continued research is crucial for further optimizing NMO patient care.
