NARA, Japan — Microcornea or microphthalmos may be a risk factor for secondary glaucoma in eyes that have undergone pediatric pars plana lensectomy, according to a study here. Careful follow-up of intraocular pressure after pars plana lensectomy for congenital cataract is recommended, study authors advise.

Researchers here studied 80 eyes of 44 patients with congenital cataract who underwent pars plana lensectomy. Follow-up was at least 36 months. Mean age at time of the lensectomy was 11 months.

An elevation in intraocular pressure (>20 mm Hg) was found in 21 eyes of 12 patients. In seven of those eyes, surgical treatment was required. The incidence of microcornea or microphthalmos with the congenital cataract was significantly higher in the glaucoma group than in the nonglaucomatous group.

The study is published in the February issue of Clinical Investigation.
