The efficacy of neodymium: YAG laser iridotomy in the treatment of closed peripheral iridotomies in silicone-oil-filled aphakic eyes.

Eighteen patients had a surgical inferior peripheral iridotomy performed to prevent pupil block and silicone oil anterior chamber prolapse. The occlusion of an iridotomy was treated by neodymium: YAG laser therapy and this form of treatment was successful only in 4 cases (22%). The reopening of occluded iridotomies is best performed by surgery as opposed to laser treatment.
