Clinical treatment for secondary glaucoma due to silicone oil migrating into anterior chamber / 第三军医大学学报

ABSTRACT

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.
