Pain Management During Panretinal Photocoagulation for Diabetic Retinopathy: Safety and Efficacy of Peribulbar Anesthesia
2026년 6월 8일 업데이트: Asociación para Evitar la Ceguera en México
Safety and Efficacy of Peribulbar Anesthesia for Pain Management in Patients With Proliferative Diabetic Retinopathy During Panretinal Photocoagulation
The purpose of this study was to compare two different anesthesia methods for pain control during panretinal photocoagulation (PRP), a type of laser surgery that treats proliferative diabetic retinopathy (PDR).
The study included eyes from patients with diabetes and proliferative diabetic retinopathy who were scheduled to undergo their first PRP session. Participants were split into two groups to receive either peribulbar anesthesia, which is a type of anesthesia injected through the eyelid, or a sham injection with topical anesthesia only.
Pain on a numerical scale and vital signs were recorded before and for 15 minutes during PRP. These results were compared between the two groups to determine which method delivers superior pain control.

실험적: Peribulbar anesthesia intervention group
The intervention administered was topical anesthesia with peribulbar anesthesia consisting of a lidocaine and bupivacaine injection.
|
A mixture of 1.5 mL of 0.5% bupivacaine and 1.5 mL of 2% lidocaine was prepared in a 3 mL syringe.
The peribulbar injection was administered using a 25G needle inserted horizontally through the inferior palpebral conjunctiva, directed axially over the infraorbital rim, and then angled upward to deliver the anesthetic into the orbit.
A single drop of topical 5% tetracaine

가짜 비교기: Control group
The control group received only topical anesthesia and a sham peribulbar injection.

Pain perception during PRP administration
기간: Pain on the NRS scale was measured at the 1-, 5-, 10-, and 15-minute marks while undergoing PRP application in each eye.
|
patient perception of pain during PRP administration in each eye, measured using the Numerical Rating Scale (NRS).
The NRS measures pain intensity on a scale of 0 to 10, where 0 corresponds to the absence of pain and 10 represents the worst pain imaginable.
|
Pain on the NRS scale was measured at the 1-, 5-, 10-, and 15-minute marks while undergoing PRP application in each eye.
