RESUMO
A cataract extraction and primary capsulotomy with intraocular lens (IOL) implantation was performed on a 17-day-old infant with a monocular mature congenital cataract. The IOL power, calculated at the time of surgery, was undercorrected to compensate for the growth of the eyeball. Two additional surgical procedures were required to resolve visual axis obstruction caused by lens epithelial cell proliferation. Follow-up was 18 months, during which amblyopia prevention therapy was instituted.

A technique is presented for computed tomography (CT)-guided interstitial catheter placement and treatment planning for high-dose-rate brachytherapy. In a 66-year-old woman with adenocarcinoma of unknown origin that had metastasized to the right ilium, interstitial brachytherapy catheters were placed by means of CT guidance. With use of a treatment planning system with dose optimization, an excellent dose distribution was obtained with minimal dose being delivered to the surrounding critical tissues. For selected patients, this procedure can provide effective and safe local treatment for solid tumors.

Excessive eye elongation can be induced in experimental animals by visual deprivation. A tendency toward myopic refraction or shift in pediatric aphakia has been recorded in some children. In this report, we present the case of an 18-year-old patient who had developmental cataracts treated at seven years of age with bilateral cataract extraction and implantation of an intraocular lens in one eye only. Axial length of the eye with a contact lens increased compared with the eye with the intraocular lens.
