What likely diagnosis corresponds to a child presenting with bilateral eye redness and watery discharge without purulent exudate?

The presentation of bilateral eye redness and watery discharge is highly indicative of viral conjunctivitis. This condition typically occurs without purulent exudate, which distinguishes it from bacterial conjunctivitis that often presents with significant discharge. Viral conjunctivitis is commonly caused by adenoviruses and is associated with symptoms such as itching or burning sensations in the eyes, along with the redness and watery discharge noted in this scenario. The bilateral nature of the symptoms further supports the diagnosis of viral conjunctivitis, as it commonly affects both eyes simultaneously.

In contrast, while allergic conjunctivitis can also cause redness and watery discharge, it is usually accompanied by intense itching and other allergic symptoms such as sneezing or nasal congestion. Bacterial conjunctivitis generally presents with purulent discharge, which is not mentioned in this case and suggests that it is less likely. Bacterial keratitis would also present with significant eye pain, blurred vision, and various other symptoms indicating corneal involvement, making it unlikely in this case. Thus, the combination of bilateral eye redness, watery discharge, and the absence of purulent exudate is a clear indicator of viral conjunctivitis.
