Abstract

fetched live from OpenAlex

Introduction. Neisseria meningitidis is a Gram-negative diplococcus with significant infectious sequelae, including meningitis and disseminated meningococcal bloodstream infection. Rarely has it been reported in the context of endophthalmitis without central nervous system involvement. We report a clinical case of isolated meningococcal endophthalmitis in an immunocompetent patient and present a literature review on published cases, including treatment regimens and clinical outcomes. Case Presentation. A 51-year-old male with no significant medical history presented to the emergency department with acute vision loss in the right eye after returning from Mexico. Ophthalmic examination was consistent with endophthalmitis, presumed to be endogenous in the absence of recent ocular trauma or surgery. Vitreous culture was positive for growth of Gram-negative diplococci, subsequently identified as N. meningitidis . Blood and cerebrospinal fluid cultures were negative for growth of similar or implicative pathogens. There was no evidence of disseminated meningococcal infection; imaging did not demonstrate any drainable collections or sequelae of extension into the central nervous system. The patient was treated with intravitreal antibiotics as well as topical steroids and antibiotics. In addition, he completed a 2-week course of systemic antibiotics. Visual outcome was unfortunately poor. Conclusion. This case illustrates a rare case of isolated endophthalmitis secondary to meningococcus, presumably from a nasopharyngeal source. In these clinical scenarios, clinicians should perform a thorough evaluation for predisposing immunodeficiencies.

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
