About

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.

Full description

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.
