Which items should be assessed in history for acute vision changes?

• A. Onset, duration, pain, and associated symptoms such as flashes or floaters
• B. Past ocular surgeries only
• C. Color vision testing results
• D. Blood pressure readings

Answer: (A)

In acute vision changes, the most informative history comes from when it started, how long it has lasted, whether there is eye pain, and any associated phenomena like flashes or floaters. Timing helps distinguish sudden emergencies (such as retinal artery occlusion, retinal detachment, or acute angle-closure glaucoma) from slower, less urgent changes. The duration of symptoms aids in judging stability and how urgently to respond. Pain points to inflammatory or pressure-related processes, while a painless vision change raises suspicion for retinal, optic nerve, or vascular events. Flashes of light and floaters specifically hint at vitreoretinal problems, including tears or detachment. Collecting these details quickly guides triage, prioritizes urgent evaluation, and directs immediate testing and treatment.

Past ocular surgeries alone doesn’t capture the current event’s characteristics. Color vision testing is a useful exam finding but not a historical clue. Blood pressure readings are important for overall risk assessment but don’t define the cause or urgency of the acute vision change from history alone.
