Objective: Orbital apex syndrome (OAS) is a rare condition with multiple cranial nerve involvement caused by varied etiologies. It is not only a threat to the patient's vision but also life-threatening due to the intracranial spread of infection, if not diagnosed early and treated accurately. To study the outcome of endoscopic sinus surgery (ESS) for OAS secondary to sinusitis concerning resolution of ptosis, improvement of ophthalmoplegia, visual prognosis, intracranial spread of infection, and mortality., Methods: A retrospective review of patients with OAS secondary to sinusitis who underwent ESS from 2011 to 2021 was tabulated and analyzed., Results: Twenty-seven patients (mean age: 55.11+/-16 years; male 62%) were included in this study. At presentation, blurring of vision (81%), headache (66%), diplopia (63%) ptosis (63%) were the most common symptoms, and ophthalmoplegia (100%) was the most common sign. Five patients had no perception of light and the rest had various degrees of vision impairment. The most common etiopathology of sinusitis was fungal sinusitis (12 mucormycosis and four aspergillus). The final visual prognosis at three months follow-up post-ESS showed vision stabilization (no improvement or worsening) in 13 (48%) patients, improvement in seven (26%) patients, and vision deterioration in two (7%) patients. There was a significant improvement in ptosis (70%) and ophthalmoplegia (85%). There was no intracranial spread of infection or recurrence with a mortality rate of 3.7% (one patient)., Conclusion: ESS coupled with appropriate antimicrobials effectively treats OAS secondary to sinusitis with decreased morbidity and mortality., Competing Interests: Conflict of Interest: The authors have no conflicts of interest to declare., (©Copyright 2024 by Turkish Otorhinolaryngology- Head and Neck Surgery Society / Turkish Archives of Otorhinolaryngology is published by Galenos Publishing House.)

Purpose: To determine the association between systemic vitamin D (VD) and immunoglobulin E (IgE) levels with severity and ocular surface inflammatory profile in patients with epidemic keratoconjunctivitis (EKC)., Methods: 210 eyes of 105 patients who were clinically diagnosed with EKC were included in the study. The levels of serum VD and serum IgE were measured. Schirmer's strip-based tear fluid (TF) was used to determine levels of IL-1β, IL-6, IL-10, IL-17A, TNFα, MMP9, sICAM1, and VEGF-A in a subset of patients., Results: Levels of VD were significantly ( P < 0.05) lower and levels of IgE were significantly higher in patients with severe forms of conjunctivitis compared to those with nonsevere forms. Majority of the patients with severe forms of the disease exhibited VD deficiency and/or abnormally high IgE. A negative correlation (r = -0.682; P < 0.0001) was observed between VD and IgE levels. TF levels of IL-1β, IL-6, TNFα, and sICAM1 were significantly higher in eyes with severe forms of conjunctivitis compared to those with nonsevere forms and controls. These factors showed a positive correlation ( P < 0.05) with IgE levels and a negative correlation ( P < 0.05) with VD levels., Conclusion: Patients with severe forms of EKC exhibited VD deficiency and higher levels of IgE. Increased TF inflammatory factors demonstrated a disease causal relationship with VD and IgE. Hence, restoring the altered levels of VD and IgE to normal range would be pivotal in the prevention and management of severe conjunctivitis., (Copyright © 2024 Copyright: © 2024 Indian Journal of Ophthalmology.)

Neonatal orbital complications are rare and potentially fatal, demanding prompt diagnosis and adequate treatment. A 25-day-old neonate presented with rapidly progressive orbital complications as evidenced by proptosis, chemosis, lid oedema and restricted eye movements, developing within 3 days. There was no significant medical history or risk factors for developing infection. An initial conservative approach with antimicrobial therapy failed to show any resolve. An MRI brain, orbits and paranasal sinuses demonstrated that there were features suggestive of right orbital cellulitis with possibility of abscess formation with right ethmoidal mucoinflammatory disease and mass effect on the optic nerve causing stretching and compression by the surrounding inflammation.The patient was treated successfully with transnasal endoscopic drainage and decompression. Endoscopic access was challenging owing to the restrictive anatomy. Postoperatively, the patient showed improvement, with gradual decrease in proptosis and resolve in eye movements., Competing Interests: Competing interests: None declared., (© BMJ Publishing Group Limited 2023.
