How can Neisseria gonorrhoeae be detected in ocular specimens?

Explanation:
The key idea is that gonococcal eye infection is most reliably suggested by a Gram stain of the eye discharge showing intracellular Gram-negative diplococci inside neutrophils. This finding is classic for Neisseria gonorrhoeae and provides a rapid, highly specific clue that prompts urgent treatment and confirmatory culture on selective media. Other stains don’t target these bacteria: Ziehl-Neelsen is for acid-fast organisms like Mycobacterium, Calcofluor white highlights fungi, and Giemsa isn’t the standard method for identifying gonococci in ocular specimens.
