PURPOSE: To describe pupil block glaucoma in phakic and pseudophakic patients after vitrectomy with silicone oil injection. DESIGN: Interventional case series. METHODS: Cases were collected from January 1997 to July 2000 from three tertiary referral centers, RESULTS: Seven phakic patients (seven eyes) and one pseudophakic patient (one eye) presented one to 90 days after vitrectomy and silicone oil injection with intraocular pressures (IOPs) of 36-70 mmHg. Five patients had an observed or potential weakness of the iris-lens diaphragm. Treatment with Nd:YAG laser peripheral iridotomy or inferior iridectomy provided a temporary reduction of IOP in some patients, but all eventually required removal of silicone oil. CONCLUSIONS: Pupil block glaucoma after silicone oil injection is well recognized in aphakic patients, but ophthalmologists should be aware that it can also occur in phakic and pseudophakic patients, particularly in complicated cases and in patients with a weakness of the iris-lens diaphragm.
