If it remains untreated, it can cause damage and significant vision loss. Piperacillin\/tazobactam (PIP\/TAZ) exerts broad activity against most gram\u2010positive and gram\u2010negative aerobic and anaerobic bacteria, including many pathogens producing beta\u2010lactamases. It is administered for the treatment of moderate\u2010to\u2010severe bacterial infections. Ocular adverse reactions after the administration of PIP\/TAZ have been rarely reported.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Case Presentation<\/jats:title>\n                    <jats:p>We report a case of a 32\u2010year\u2010old woman, who developed pelvic abscess and sepsis, as a complication of caesarean section. She experienced bilateral optic disc edema with associated intraretinal and subretinal fluid during PIP\/TAZ therapy. PIP\/TAZ was discontinued the fourth day of its administration and was substituted with ertapenem. Progressive resolution of optic disc edema in both eyes, with complete normalization of the fundus and retinal nerve fiber layer thickness, was observed 2\u2009months after drug discontinuation. However, persistent bilateral discontinuity of the foveal ellipsoid zone remained.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Bilateral optic disc edema with serous retinal fluid after PIP\/TAZ therapy is very rare. Prompt discontinuation of the medication and ophthalmic evaluation should be immediately considered when visual symptoms arise. Further pharmacovigilance reporting is warranted to clarify the rarity of this adverse effect after PIP\/TAZ administration.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1155\/crdi\/2925958","type":"journal-article","created":{"date-parts":[[2026,7,13]],"date-time":"2026-07-13T10:26:18Z","timestamp":1783938378000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Piperacillin\/Tazobactam\u2010Induced Bilateral Optic Disc Edema With Serous Retinal Fluid in a Young Female With Pelvic Abscess and Sepsis"],"prefix":"10.1155","volume":"2026","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8143-7145","authenticated-orcid":false,"given":"Georgios","family":"Papaetis","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0006-3052-9230","authenticated-orcid":false,"given":"Ioannis","family":"Kazakos","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0006-6406-0194","authenticated-orcid":false,"given":"Eleftheria","family":"Lazarou","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1134-6176","authenticated-orcid":false,"given":"Pantelis","family":"Kountourakis","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0005-7632-951X","authenticated-orcid":false,"given":"Charis","family":"Antoniou","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0008-3439-5959","authenticated-orcid":false,"given":"Konstantinos","family":"Mikellidis","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,7,13]]},"reference":[{"key":"e_1_2_12_1_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.survophthal.2021.11.007"},{"key":"e_1_2_12_2_2","doi-asserted-by":"publisher","DOI":"10.1177\/08465371211061660"},{"key":"e_1_2_12_3_2","doi-asserted-by":"crossref","first-page":"734","DOI":"10.1001\/jamaophthalmol.2022.0261","article-title":"With Normal Intracranial Pressure","volume":"140","author":"Swaminathan V.","year":"2022","journal-title":"JAMA Ophthalmol"},{"key":"e_1_2_12_4_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.neuchi.2021.04.017"},{"key":"e_1_2_12_5_2","doi-asserted-by":"publisher","DOI":"10.2147\/eb.s69174"},{"key":"e_1_2_12_6_2","doi-asserted-by":"publisher","DOI":"10.1097\/wno.0000000000001225"},{"key":"e_1_2_12_7_2","first-page":"1125","article-title":"Papilledema: Clinical Clues and Differential Diagnosis","volume":"45","author":"Whiting A.
