A 5-year-old child presents to the pediatric clinic with a mother who is very alarmed by a bright red patch on the left eye that appeared after a severe bout of coughing. On examination, the structure marked **A** in the diagram—a sharply demarcated bright red patch—is visible. The child is otherwise comfortable, has no eye pain, and vision is normal. The mother asks if this is serious and requires urgent treatment. Based on the appearance and clinical presentation, what is the most appropriate management?

Explanation

The sharply demarcated bright red patch marked **A** is the classic appearance of subconjunctival hemorrhage—bleeding into the potential space between conjunctiva and sclera. According to Khurana Ophthalmology 7e, subconjunctival hemorrhage is a benign, self-limiting condition that appears as a thin film of bright red blood with sharp demarcation, is painless, causes no visual disturbance, and resolves spontaneously over 1–2 weeks without active treatment. The post-tussive history (coughing) is the most common cause in children. Despite being alarming in appearance, it requires only reassurance, observation, and cool compresses for the first 24 hours. No topical medications or urgent imaging are indicated in uncomplicated cases with normal vision and no posterior extension.
