Open Angle Glaucoma: Treatment01:27

Open Angle Glaucoma: Treatment

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...
Angle Closure Glaucoma: Treatment01:28

Angle Closure Glaucoma: Treatment

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...

Area of Science:

  • Ophthalmology
  • Neurosurgery
  • Otolaryngology

Context:

  • Endoscopic optic nerve decompression is an emerging surgical technique.
  • This procedure is increasingly utilized for various optic nerve pathologies.

Purpose:

  • To present a clinical series of eight patients undergoing endoscopic optic nerve decompression.
  • To discuss the technical aspects and surgical anatomy of the transnasal transethmoidal approach.

Summary:

  • Eight patients with posttraumatic optic neuropathy, optic neuritis, or orbital apex cystic lesions underwent endoscopic optic nerve decompression.
  • Visual acuity improved in 50% of patients; complications included cerebrospinal fluid leaks in two cases.

Impact:

  • Endoscopic optic nerve decompression offers a viable option for selected patients with optic nerve compromise.
  • Success hinges on surgical skill, anatomical knowledge, and interdisciplinary collaboration to mitigate risks.
