Abstract

BACKGROUND:

Our objective was to evaluate the new method of ultrasound biomicroscopy in examining the anterior segment of the eyes of infants.

METHODS:

The infant was held supine during examination, which was performed under topical anesthesia only. One drop of proparacaine was placed in the eye, and a small lid speculum was inserted. The palpebral fissure was filled with 2.5% methylcellulose as a coupling medium. The ocular cup was not used. Scanning was performed by placing the probe close to the area of interest.

RESULTS:

Case 1: A 3230-g male infant was delivered by cesarean section at 39 weeks' gestation. The left eye was studied with ultrasound biomicroscopy. Examination revealed a narrow angle with the anterior chamber angle of 25 degrees. The trabecular-ciliary process distance was 510 microns. The depth of the anterior chamber was 1414 microns. Case 2: A 1368-g female infant was delivered by cesarean section at 30 weeks' gestation. The left eye was studied. The anterior chamber angle was 16 degrees. The trabecular-ciliary process distance was 380 microns. The depth of the anterior chamber was 1134 microns.

CONCLUSION:

Ultrasound biomicroscopy is clinically feasible in infants and has a potential for use in clinical research. Additional study is needed to assess the reproducibility of the measurements and to acquire additional clinical experiences.
