Which practice is recommended when monitoring corneal ulcers to reduce glare and artifacts during examination?

• A. Minimize objects in reflection
• B. Avoid red or white clothing
• C. Use flash illumination continuously
• D. Examine in a bright room with overhead lighting

Answer: (A)

Controlling glare during corneal ulcer assessment is about minimizing reflective surfaces in the visual field. When bright light from the exam setup or from surrounding objects bounces off shiny surfaces, it creates reflections that mimic or obscure corneal features, making it hard to discern ulcer margins, depth, and surface irregularities. Keeping the environment free of reflective items and positioning lighting to avoid direct reflections allows a clearer view of the ulcer and more accurate monitoring of healing, edge definition, and staining using fluorescein. The other approaches would tend to worsen glare or do not specifically reduce reflections that cloud the examination: bright clothing or flashy surfaces can contribute to reflections, constant flash illumination adds glare, and a very bright room with overhead lighting increases stray light rather than minimizing it.
