How would you manage a patient who develops a 1 mm abscess at the internal os of the paracentesis tract following an AC tap after an Izervay injection with eye pain but no vitreous cell or retinal involvement?

It sounds like a very specific question! Never having seen a paracentesis ulcer after 30 years of surgeries with paracenteses from iris hooks, and >10s of thousands of injections (albeit mostly without paracenteses), I'd have to say this is rarer than endophthalmitis. Treat it like a corneal ulcer. Consult your anterior colleagues. If you start seeing more of these, ask if it is the novel drug, contaminated supplies (needle), or something else.
