Objective    To explore the clinical therapeutic methods for secondary glaucoma induced by the migration of silicone oil into the anterior chamber.      Methods    Totally 26 cases of such secondary glaucoma

including 22 aphakic eyes and 4 phakic eyes were subjected. Silicone oil was directly taken out for the patients whose retina was reposited well after silicone oil injection for over 3 months. The aphakic patients underwent 6 o’clock position peripheral iridectomy with laser or operation on prone position

then silicon oil was reinjected

and trabeculectomy was carried out through inferior cornea. The phakic patients received silicone oil aspiration with Healon from the anterior chamber. When silicone oil remigrated into the anterior chamber

the crystal was resected

silicone oil was reinjected

and 6 o’clock position peripheral iridectomy were performed. The patients were followed up for 3 months after the intraocular pressure (IOP) reaching normal range.     Results    Except one patient gave up treatment

all the patients had stable and normal IOP after 3 months of follow-up. IOP was controlled through different methods in 21 aphakic eyes: 5 with prone position

5 with 6’clock position peripheral iridectomy through laser or operation

4 with silicon oil reinjecting

2 with direct aspiration of silicone oil

and 3 with trabeculectomy under cornea. IOP was controled in all of phakic eyes: 3 with Healon aspiration of silicone oil

1 with crystal resection and reinjection of silicone oil.      Conclusion    Secondary glaucoma induced by migration of silicone oil into the anterior chamber can be satisfactorily treated by many ways.
