Is the phakic eye normal in monocular pediatric aphakia?
This retrospective review of 97 pediatric patients who underwent monocular surgery for congenital or developmental cataracts studied the incidence of abnormalities in the contralateral phakic eye. Fifty-nine percent of patients had a normal phakic eye. However, 40 patients showed at least one abnormality in the phakic eye: reduced vision (21%), nystagmus (19%), cataract (15%), iris heterochromia (9%), myopia (6%), microphthalmos (6%), pupillary miosis (2%), congenital glaucoma (2%), optic nerve abnormality (2%), aniridia (1%), and corneal opacity (1%). Not all abnormalities were detected at the time of diagnosis of the contralateral cataract. The more significant findings of reduced vision and nystagmus in the phakic eye were usually detected postoperatively, often several months after the optimum time for treatment of pediatric cataracts. We suggest that monocular cataract surgery not be delayed. This will allow the best vision to be obtained for the aphakic eye, as the "sound eye" may not always be normal in monocular pediatric aphakia.
