Which eye finding would be considered an ophthalmic emergency?

• A. Presence of chemosis
• B. Cobblestone-like inner eyelid lesions
• C. Bilateral redness with ulcers
• D. Unilateral vesicular lesions on the upper eyelid in a 3 week old

Answer: (D)

In a neonate, an eye finding described as unilateral vesicular lesions on the upper eyelid is the strongest red flag for an ophthalmic emergency because it most likely represents herpes simplex virus infection involving the eye. Neonatal HSV can be acquired at birth and can rapidly involve the eye, leading to conjunctivitis, keratitis, corneal ulcers, and even disseminated disease. The eye can deteriorate quickly, so this requires urgent ophthalmology evaluation and prompt antiviral treatment (often IV acyclovir) to protect vision and prevent spread. Infection control precautions are also important. By contrast, chemosis alone is simply conjunctival swelling seen with many nonemergent conditions such as viral or bacterial conjunctivitis or allergic reactions. Cobblestone-like inner eyelid lesions point to allergic or inflammatory conjunctival disease rather than a dangerous neonatal infection. Bilateral redness with ulcers could indicate a serious eye surface infection, but the unilateral vesicular lesion in a 3-week-old is most concerning for a potentially sight- or life-threatening neonatal HSV process and thus is the emergency finding.
