Which finding is considered an ophthalmic emergency in a neonate?

• A. Presence of chemosis
• B. Cobblestone-like conjunctival lesions
• C. Unilateral vesicular lesions on the upper eyelid
• D. Bilateral redness with ulcers

Answer: (D)

The key idea is that any sign of corneal involvement in a newborn is a medical emergency. When both eyes show redness with ulcers, it signals that the corneal surfaces are damaged in a neonate, and this can progress rapidly to perforation or severe vision loss. This pattern often points to serious infectious etiologies such as neonatal herpes or bacterial keratitis, requiring urgent ophthalmology evaluation and prompt, definitive treatment (often systemic therapy and targeted tests) to protect the eyes and prevent systemic spread. If the finding is only swelling (chemosis) without corneal ulcers, or if there are cobblestone-like lesions indicating allergic conjunctivitis, these are concerning but not as immediately threatening to the eye's structure. A unilateral vesicular lesion on the eyelid suggests localized viral involvement but does not carry the same immediate risk to both eyes as bilateral corneal ulcers; it still warrants prompt assessment, particularly to rule out herpes, but the most urgent red flag remains bilateral corneal involvement with ulcers.
