Final answer:
Viral epidemic keratoconjunctivitis is typically an inflammation of both the cornea and conjunctiva, most often caused by adenoviruses or herpes simplex virus 1, and may require antiviral medications if it involves herpes keratitis.
Step-by-step explanation:
In viral epidemic keratoconjunctivitis, characteristically, there is inflammation of the cornea and conjunctiva, typically caused by viruses such as adenoviruses or herpes simplex virus 1 (HSV-1). This condition can result in symptoms like irritation, excessive tearing, and sensitivity to light. It is important to differentiate between the various types of conjunctivitis, as treatments differ.
For example, while bacterial conjunctivitis may require antibiotic treatment, viral conjunctivitis usually resolves on its own without specific antiviral medication. However, for herpes keratitis, antiviral medications may be prescribed. Laboratory testing is necessary to confirm the diagnosis, especially to identify HSV-1 as the cause for herpes keratitis, which could potentially lead to blindness if left untreated.
