In suspected dacryocystitis, which testing is included?

• A. Punctal expression, NaFl, and evaluation of pupils, EOMs, exophthalmometry, and temperature
• B. Visual field testing and intraocular pressure
• C. Fundus exam only
• D. Color vision testing

Answer: (A)

Assessing lacrimal drainage status and screening for orbital involvement is essential when dacryocystitis is suspected. Punctal expression lets you evaluate the lacrimal sac directly—you can feel for tenderness and observe any purulent material or regurgitation when pressure is applied over the sac, which supports an infection of the drainage system. Using fluorescein (NaFl) helps confirm patency and reveals regurgitation through the puncta when appropriate pressure is applied, providing practical evidence of blockage and sac involvement. At the same time, checking the pupils, extraocular movements, exophthalmometry, and temperature is crucial to detect signs that the infection may be spreading beyond the lacrimal sac into the orbit or causing systemic illness. Abnormal pupil responses or restricted eye movements can signal orbital involvement; proptosis on exophthalmometry suggests orbital extension; fever or a systemic temperature rise points to a more serious infection requiring urgent attention. Other tests like visual field testing with IOP, a fundus-only exam, or color vision testing don’t specifically assess the lacrimal drainage system or potential orbital involvement, so they’re not as informative for suspected dacryocystitis. This combination of lacrimal system assessment plus orbital/systemic screening provides the most comprehensive, actionable evaluation in this scenario.
