Urrets-Zavalia syndrome (UZS) stands out as a rare yet clinically consequential complication associated with ophthalmic surgery, marked by the emergence of a fixed and dilated pupil. While it was originally described post-penetrating keratoplasty (PKP) in patients with keratoconus and its prevalence is notably higher following PKP, instances of UZS have been documented in the context of other procedures, including intraocular lens implantation, Descemet-stripping endothelial keratoplasty and Descemet membrane endothelial keratoplasty (DMEK). We report a unique case of bilateral UZS after uneventful DMEK surgeries, highlighting a rare but potential complication after DMEK.

Background: Blood pressure management is extremely important to prevent cerebral hypoxia and influence the outcome of critically ill patients. In medicine, precise instruments are essential to increase patient safety in the intensive care unit (ICU), including intracranial compliance (ICC) monitoring. A new technology developed by Brain4care, makes it possible to analyze the waveform of intracranial pressure (ICP) non-invasively associated with ICC, and this instrument was used in the patient for monitoring.
