Angle Closure Glaucoma: Treatment01:28

Angle Closure Glaucoma: Treatment

918
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...

Glaucoma: Overview

1.0K
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: Treatment

783
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...

Area of Science:

  • Neurology
  • Headache Medicine

Background:

  • Cluster headache is a severely disabling primary headache disorder.
  • It is considered one of the most painful conditions known to humans.

Purpose of the Study:

  • To review clinical characteristics, epidemiology, risk factors, diagnosis, pathophysiology, and treatments for cluster headache.
  • Emphasis on recent advancements in the field.

Main Methods:

  • A structured literature review was conducted on cluster headache.

Main Results:

  • Affects approximately 1 in 1000 individuals, characterized by severe unilateral head pain and autonomic symptoms.
  • Pathophysiology involves the hypothalamus and trigeminovascular system.
  • Effective treatments include parenteral triptans, high-flow oxygen, verapamil, corticosteroids, and greater occipital nerve injection. Novel therapies are emerging.

Conclusions:

  • Recognizing distinctive cluster headache symptoms allows for effective management with established treatments.
  • Newer pharmacological and neuromodulation therapies, driven by recent pathophysiological insights, are expected to become standard clinical practice.
