Objective: To evaluate changes in retinal nerve fiber layer (RNFL) and macular thicknesses, included ganglion cell-inner plexiform layer (GCIPL) thickness, in patients with spontaneous intracranial hypotension (SIH).
Methods: This was a retrospective, nonrandom, observational case series study. Comprehensive ophthalmic examinations and systemic examinations were performed. Spectral domain optical coherence tomography angiography scanning was used to measure peripapillary RNFL thickness and macular volume.
Results: In total, 108 eyes in 54 patients with SIH were evaluated; these were compared with 108 eyes in 54 healthy controls. The mean ages were 38.2 ± 9.4 years (patients with SIH) and 38.9 ± 9.4 years (healthy controls). In both groups, 33 patients were women (61.1%). The peripapillary RNFL and GCIPL were thinner in patients with SIH than in healthy controls (100.08 ± 9.94 µm 104.83 ± 8.35 µm and 81.46 ± 5.67 µm 85.67 ± 4.57 µm, respectively). Among patients with SIH, the GCIPL was thinner in patients with visual field defects (79.81 ± 5.62 µm 82.39 ± 5.12 µm).
Conclusions: The RNFL and GCIPL were thinner in patients with SIH than in healthy controls. The GCIPL was thinner in eyes with visual field defects among patients with SIH.

Introduction: This is a structured scoping review to assess whether there is a relationship between stress-induced hyperglycemia (SIH), cytokine interactions, and mortality in trauma patients in comparison to non-diabetic normoglycemia [NDN], diabetic normoglycemia [DN], and diabetic hyperglycemia [DH].
Methods: We conducted a literature search of MEDLINE (PubMed) databases from 2000 to 2022 using a search strategy to identify observational studies. Initially, 2879 articles were retrieved.
Mild cognitive impairment in spontaneous intracranial hypotension and its rapid reversal by repair of a spinal cerebrospinal fluid leak.

Background: Patients with spontaneous intracranial hypotension (SIH) report difficulties in concentration and memory. To objectify these deficits, we implemented standard cognitive tests into our routine SIH workup.
Method: Retrospective, single-center report of cognitive standard tests among patients with SIH consecutively admitted from May to July 2023.

Objective: Frontotemporal dementia (FTD) sagging brain syndrome is a disabling condition. An underlying spinal Cerebrospinal fluid leak can be identified in only a minority of patients and the success rate of non-directed treatments is low. Some of these patients have a remote history of craniectomy/cranioplasty and we report a positive response to custom implant cranioplasty revision many years after their initial cranioplasty.

Background: Epidural blood patching (EBP) is the primary treatment for spontaneous intracranial hypotension (SIH), although multiple attempts may sometimes be necessary. The SIH-EBP score, with a cutoff of ≥3, predicts the response to the first EBP. However, its generalizability requires further confirmation.
