“…The available literature is mainly focused on comparing the efficiency and safety of different laser devices and the effectiveness of new laser technologies. 1,2,4,11 At the same time, most of the research in ophthalmic analgesia was focused on the efficacy and safety of different anesthetic procedures and drugs for surgical procedures, particularly cataract surgery, 12,13,14 glaucoma surgery 15,16 or during vitreoretinal treatments. 17,18 The present study offered insights into the analgesia techniques for PRP by comparing topical anesthesia with a combined approach using topical and subconjunctival anesthetic injection.…”

Purpose comparison between two anesthetic techniques on the ability to reduce pain during panretinal photocoagulation (PRP) treatment. Methods Observational retrospective single center study. Medical charts of patients who underwent PRP for proliferative diabetic retinopathy were revised. Patients were included if they had the first eye treated with oxybuprocaine hydrochloride drops, and in case of severe pain, the fellow eye received topical anesthesia in combination with 2% subconjunctival lidocaine. The groups were compared for pain perception using an analog visual scale (VAS), number of laser spots, number of interruptions, and laser session duration. Results Forty-two eyes of 21 patients (mean age: 58.3 ± 7.6 years) were analyzed. The mean number of laser spots was significantly higher under combined anesthesia (+84.2 ± 155.9 spots, p = 0.01), with a reduced time for laser execution (−2.5 ± 3.12, p = 0.0008). The use of combined anesthesia significantly decreased the number of interruptions (−40.8%, p < 0.0001) into a single session. On the pain grading scale, the pain perception was significantly lower in the combined anesthesia group ( p < 0.0001). In eyes receiving topical anesthesia the treatment was stopped for pain in 5 eyes (23.8%), while 5 eyes under combined anesthesia presented subconjunctival hemorrhage (23.8%). Conclusion Using combined anesthesia in patients subjected to PRP appeared to reduce pain perception limiting the treatment duration and the interruptions for pain without significant complications. Further studies on a larger scale would be desirable to replicate such findings and standardize the analgesic procedures in ophthalmology.
