Open Angle Glaucoma: Treatment01:27

Open Angle Glaucoma: Treatment

375
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

413
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...

Suctioning the Nasopharyngeal Airway

227
Nasopharyngeal suctioning is a procedure to remove secretions from the upper part of the respiratory tract that the patient cannot clear independently. It helps maintain airway patency and prevents complications such as aspiration pneumonia.

Summary
This summary is machine-generated.

This systematic review evaluates treatments for functional epiphora (excessive tearing) in adults. Dacryocystorhinostomy (DCR) shows the highest success rate, with minor complications, guiding a new management algorithm.

Area of Science:

  • Ophthalmology
  • Oculoplastics
  • Tear Drainage System Disorders

Background:

  • Functional epiphora, characterized by excessive tearing with a patent lacrimal system, affects adults.
  • Effective management strategies are crucial for improving patients' quality of life.

Purpose of the Study:

  • To systematically review the success rates and complications of various interventions for adult functional epiphora.
  • To propose an evidence-based management algorithm for this condition.

Main Methods:

  • Systematic review of English-language articles from PubMed, SCOPUS, and Google Scholar.
  • Inclusion of studies on surgical or non-surgical treatments for functional epiphora in adults (≥18 years).
  • Quality assessment using the Effective Public Health Practice Project checklist.

Main Results:

  • Twenty-eight studies met the criteria, with silicone tube intubation frequently used with dacryocystorhinostomy (DCR).
  • Dacryocystorhinostomy (DCR) demonstrated the highest success rate and longest follow-up.
  • Complications were generally minor, transient, and primarily stent-related.

Conclusions:

  • A proposed management algorithm begins with dacryocystography (DCG) for all functional epiphora patients.
  • DCR is recommended for abnormal DCG or post-sac delay on dacryoscintigraphy (DSG).
  • Lateral tarsal strip for pre-sac delay and botulinum toxin A as a short-term option for normal DSG are suggested.
