Regarding SPL in therapy, which statement is true?

• A. SPL can be preloaded or elastomeric
• B. SPL must be refrigerated at all times
• C. SPL requires general anesthesia
• D. SPL is a diagnostic blood test

Answer: (A)

Subpalpebral lavage is a therapeutic delivery system that places a small cannula under the eyelid to administer medications directly to the ocular surface. The reservoir for the medication can be preloaded or connected to an elastomeric pump, providing a continuous, controlled flow to the eye. This flexibility—having a ready-made, prefilled setup or an elastomeric reservoir—explains why that statement is true. Placement does not require general anesthesia, as sedation with local anesthesia is commonly sufficient, and it’s not a diagnostic blood test. Refrigeration needs depend on the particular drug in the reservoir, not the SPL concept itself.
