Abstract
- Local anesthesia in strabismus surgery allows for the evaluation of ocular alignment during the operation and enables early postoperative recovery.However, extraocular muscle traction results in decreased heart rate and discomfort for the patient. Therefore, it is our attempt to reveal the degree of of decreased heart rate during extraocular muscle traction and the patient`s pain perception. This was done prospectively on personalities of the patient, preoperative heart rate in the operating room, change of heart rate and pain perception of the patient during surgery. The statistically significant decrease in heart rate due to the ocular cardiac reflex occurs during medial rectus resection, lateral rectus recession, and leads to less satisfaction in the anxious patients. Strabismus surgery under topical anesthesia does not decrease the heart rate significantly, therefore it is relatively safe and the patient`s personality was influence on the intraoperative pain perception of the patients.
