PURPOSE: To compare anterior segment parameters in healthy children of the same age with those in children with phenylketonuria (PKU).
STUDY DESIGN: Retrospective observational study METHODS: Data from 25 eyes of PKU patients (study group) and 60 eyes of age- and gender-matched children (control group) were analyzed. The records reviewed included results from a comprehensive ophthalmic evaluation that each participant had previously undergone. This evaluation included refraction evaluation (spherical equivalent), best corrected visual acuity (BCVA) testing, slit-lamp biomicroscopy, fundus examination, intraocular pressure (IOP) measurement, specular microscopy, and corneal topography measurement.
RESULT: Forty-five (52.9%) age- and sex-matched participants were girls and 40 (47.1%) were boys. The percentage of hexagonal cells (HEX) was 65.53±8.17 in the study group and 69.75±4.19 in the control group (p=0.021). Flat keratometry (K1) was 41.70±1.54 D in the study group and 43.16±1.52 D in the control group (p=0.002). Steep keratometry (K2) was 42.55±1.83 D in the study group and 43.91±1.73 D in the control group (p=0.013).
CONCLUSION: This study shows that patients with pediatric PKU have differences in the anterior segment parameters, including keratometric values and HEX, when compared with healthy controls.
