Neodymium:YAG pupilloplasty in pediatric aphakia.
An adequate pupillary aperture is required for accurate ophthalmoscopy and retinoscopy in pediatric aphakia. When pupillary miosis does not respond to pharmacologic dilation, optical iridectomy performed with a vitreous suction-cutting instrument under general anesthesia may be required. We report a 27-month-old aphakic child whose pupillary aperture was enlarged from 1 mm to 3.5 mm with neodymium (Nd):YAG pupilloplasty, following intramuscular sedation with meperidine, promethazine, and chlorpromazine. Removal of the laser chin rest and positioning of the patient on a table with adjustable height facilitated delivery of 140 applications at 2.5 to 4.3 mJ to the pupillary border. Levobunolol 0.5% controlled the transient posttreatment rise in intraocular pressure. We suggest that Nd:YAG pupilloplasty performed with sedation be considered as an alternative to intraocular surgery when pupillary miosis in pediatric aphakia does not respond to dilating agents.
