This small pupil case has a surprise in store for you. The patient has a history of prior uveitis which has been quiescent for about a year. There is a wide area of synchiae formation which prevents the pupil from dilating. The resident who is operating has a few challenges: break the synechiae, likely with viscoelastic in the eye, but then how do you stain the capsule with Trypan blue dye? Then should you place a pupil expansion ring? And how do you get a 6.25mm diameter ring to fit when the pupil is just 3.5mm? Lots of great learning, especially if you are in the first few years of practice.
