    Abstract Background: Almost one-fifth of patients undergoing surgery for sellar/supra-sellar tumors do not gain a significant improvement in their vision. Various methods have been described to predict prospective visual outcomes in them, although they lack uniformity.
    Objective: The study was conducted to predict visual outcomes following surgery for sellar and supra-sellar tumors compressing the anterior optic pathway based on pre-operative optical coherence tomography (OCT) parameters.
    Methods and materials: This was a record-based observational descriptive longitudinal study done in a tertiary care center in India. Thirty-seven patients (74 eyes) diagnosed with sellar supra-sellar lesions were included in the study. Patients' ophthalmic evaluations, done pre-operatively and 3 months post-operatively, were reviewed. Spectral-domain OCT and segmentation were done using the automated segmentation technology of Spectralis software. The thickness of the respective layers was measured.
    Results and conclusions: The mean age of the study population was 42.68 years. Eyes with a pre-operative visual acuity component of VIS (visual impairment score) ≤61, pre-operative ganglion cell layer thickness ≥26.31 um, a pre-operative inner plexiform layer thickness of ≥25.69 um, a pre-operative ganglion cell inner plexiform layer thickness of 52.00 um, pre-operative ganglion cell complex thickness ≥84.47 μm, and a pre-operative inner retinal layer thickness of ≥205.25 μm were more likely to have an improved visual outcome. Eyes with a pre-operative duration of visual symptoms of ≥15 months, VIS ≥126.50, a pre-operative decimal visual acuity of <0.035, a pre-operative visual field index of ≤8%, a pre-operative macular thickness of ≤287.06 um, a pre-operative macular RNFL (retinal nerve fiber layer) thickness ≤66.00 μm, and a pre-operative peri-papillary RNFL thickness ≤64.62 μm were unlikely to have visual improvement.

    Abstract Background and aims: The autonomic nervous system (ANS) is cardinal for systemic homeostasis. Autonomic dysfunction is prevalent in as high as 65% of patients presenting for cardiac surgery in the Indian scenario. Pre-existing cardiac autonomic dysfunction (CAD) in surgical patients can accentuate perioperative haemodynamic fluctuations during stressful intraoperative events, predispose to adverse cardiac events, and contribute to morbidity and mortality. The prevalence and predictors of CAD in the elective neurosurgical population are unknown in the Indian scenario. The current study was conducted to bridge this knowledge gap.
    Methods: In this single-centre prospective observational study conducted at a tertiary care neurosciences centre, among 400 consenting adult patients of either gender, between 18 and 80 years of age, undergoing elective neurosurgery, the preoperative ANS function at the bedside was assessed as the primary outcome measure. The ANS status was evaluated using ANSiscope™-derived indices of heart rate variability. The diagnosis of CAD was made when the ANS index exceeded a threshold of 13.5. Data regarding predictors of CAD were collected from patient records as the secondary outcome measure. Statistical analysis was done using the R software. A
    Results: The prevalence of preoperative CAD in our study population was 79.7% (319/400 patients). None of the demographic and baseline clinical characteristics we studied predicted CAD in our study.
    Conclusion: We observed a significant prevalence of preoperative CAD among elective neurosurgical patients. None of the parameters we evaluated predicted CAD in our study.

    Abstract Background: The endoscopic approach has gained popularity in cerebrospinal fluid (CSF) rhinorrhea repair with high success rates, yet recurrence is frequent. We analyzed our cases to determine the outcomes of endoscopic repair of CSF rhinorrhea and the effect of several perioperative factors on the success of repair.
    Methods: A retrospective review of 50 patients who underwent endoscopic repair of CSF rhinorrhea between January 2013 and July 2023 was performed, collecting details of presentation, surgery, and postoperative period.
    Results: The most frequent etiology was nontraumatic CSF rhinorrhea (76%), in which the defect was most commonly located at the left cribriform plate, followed by traumatic CSF rhinorrhea (24%), in which sphenoid defects were most frequent. Traumatic CSF rhinorrhea was more common among male patients and was significantly associated with anosmia. Success rate at first repair attempt was 84%. Persistent CSF rhinorrhea was present in 3 patients (6%), and 5 patients (10%) developed recurrence of CSF rhinorrhea. Overall, 7 patients required reoperation, with 100% success rate after the second surgery. The use of 3-layered repair with fat, fascia lata, and mucosal flap was protective against repair failure, whereas bilateral defects and duration of symptoms >1 year were significantly associated with repair failure. The use of lumbar drain did not demonstrate a difference in repair success rate.
    Conclusions: Endoscopic repair of CSF rhinorrhea appears to be safe and effective when performed with accurate localization of the site of the lesion and multilayered repair. Potential predictors of recurrence include bilateral and long-standing defects.
