“…Whereas the 0.75% ropivacaine group had an average difference in the patient's intraocular pressure before and 15 minutes post-injection was 4.42mmHg with the lowest intraocular pressure 8.82 ± 2.56. Thus, 0.75% Ropivacaine has a greater effect on reducing intraocular pressure compared to 0.5% levobupivacaine in peribulbar blockade for vitrectomy surgery (Anker & Kaur, 2017;Chaudhary et al, 2018;Kapoor et al, 2021;Mehta et al, 2018;Nociti et al, 2001;Saputra et al, 2021;Zhou et al, 2017). In line with the study by Pacella et al which stated that levobupivacaine caused lower IOP in several types of eye surgery compared to bupivacaine, levobupivacaine-hyaluronidase, and racemic bupivacaine-hyaluronidase (Pacella et al, 2013).…”
