Subtenon

Area of Science:

  • Ophthalmology
  • Anesthesia

Background:

  • Traditional retrobulbar and peribulbar blocks carry risks of sight-threatening complications.
  • Subtenon's anesthesia offers a safer alternative for ophthalmic procedures.

Observation:

  • This study evaluated the efficacy of Subtenon's anesthesia for extracapsular cataract extraction.
  • Patient comfort during anesthetic administration and surgical procedure pain were assessed.

Findings:

  • Subtenon's block was comfortable for 95.1% of patients and the procedure was painless in 98.0%.
  • Satisfactory akinesia was achieved in 94.5% of cases, with no major complications reported.
  • Minor events like chemosis and subconjunctival hemorrhage occurred but did not impact overall safety.

Implications:
