Defining a Small Pupil
Defining a small pupil may depend on…
Surgeon skill & technique.
Not all pupils of the same size are the same.
Pupil size is only one factor.
Iris Tissue Properties – dilates, bound down, atrophic, floppy, etc.
Causes of Small Pupil
Age-Related – Iris Atrophy
Medications – chronic pilocarpine
IFIS – Intraoperative Floppy Iris Syndrome
Posterior Synechiae – uveitis, trauma, prior surgery, angle closure
PEX – atrophy of dilator and sphincter muscles
Diabetes – autonomic neuropathy partially denervating the dilator and sphincter muscles; and rubeosis
Managing Small Pupil
Intracameral Medication: Phenylephrine / Epinephrine
Viscodilation – cohesive agents
Posterior Synechiolysis – cyclodialysis spatula or viscoelastic cannula
Pupil Stretching – Kuglen Hook for push-pull or Beehler Pupil Dilator
Iris Hooks
Pupil Expanding Devices: Malyugin Ring I-Ring Xpand
