Are you seeing this: the impact of steep Trendelenburg position during robot-assisted laparoscopic radical prostatectomy on intraocular pressure: a brief review of the literature.

With the increasing popularity, frequency, and acceptance of the robotic-assisted laparoscopic radical prostatectomy procedure, an awareness of unique intra- and postoperative complications is heightened, including that of increases in intraocular pressure. The steep Trendelenburg positioning required for operative exposure has been shown to increase this value. While the literature is infrequent and undeveloped, certain anesthetic parameters including deep neuromuscular blockade, modified positioning, and the use of dexmedetomidine have been shown to have mild-to-modest decreases in intraocular pressure for baseline. In the four randomized control trials and four observational studies that were found via PubMed/Medline search, the aforementioned techniques demonstrate some preliminary evidence of operative considerations in this unique patient population. These modifications may prove to have even greater significance in patients with pre-existing ophthalmologic pathologies, such as glaucoma, which were excluded from the studies' analyses. This review summarizes the early literature obtained in this subject, with the intent of emphasizing the initial hypotheses and identifying areas for future study.
