Subjective Pain Scoring for Subtenonal Anesthesia During Vitrectomy

Subtenonal anesthesia is a well-known technique of local anesthesia for patients undergoing pars plana vitrectomies. It was described to be efficient with respect to anesthesia of the eye and it showed less risks compared to retrobulbar or parabulbar anesthesia. Purpose of the study is to assess subjective pain scores of patients, that underwent vitrectomy with subtenonal anesthesia.

About this study

Subtenonal anesthesia is a well-known technique of local anesthesia for patients undergoing pars plana vitrectomies. It was described to be efficient with respect to anesthesia of the eye and it showed less risks compared to retrobulbar or parabulbar anesthesia. Subjective pain scores of patients, that underwent vitrectomy with subtenonal anesthesia, are probably different among patients with excessive indentation of the bulbus for retinal detachment repair, compared to patients undergoing vitrectomy with membrane peeling for epiretinal membranes or full thickness macular holes. Purpose of the study is to assess subjective pain scores of patients, that underwent vitrectomy with subtenonal anesthesia.

Who can participate

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • Vitrectomy with subtenonal anesthesia in the time-period from 1.12.2022 to 31.8.2023
  • Indication for surgery: retinal detachment, epiretinal membrane, or full thickness macular hole
  • Questionnaire for subtenonal anesthesia was already answered by the patients
  • Age 18 and older

Exclusion criteria

Any of the following will exclude a subject from the study:

  • Surgery in general anesthesia
  • Questionnaire missing or incomplete

Treatment and study plan

subjective pain score assessment

Other

a questionnaire assessing subjective pain during surgery, using the Visual Analogue Scale with values from 0 to 10

Primary outcomes

  1. subjective pain score during surgery

    Time frame: assessed within 24 hours sfter surgery

    subjective pain score during surgery are assessed with Visual Analogue Scale from 0 to 10. The value of 0 represents no pain and the value of 10 represents the highest pain that can be imagined.
