Abstract
Introduction
Intrauterine growth restriction (IUGR), resulting in a birth weight small for gestational age, is a recognized risk factor for neurological deficits later in life. In a recent study, it was found that IUGR was associated with reduced axonal area in the optic nerve at young adult age.1
Objective
To evaluate the influence of IUGR on visual function.
Design and methods
The authors studied 25 IUGR subjects and 21 carefully matched normal controls, using Snellen visual acuity (VA), full-threshold frequency-doubling technology (FDT) perimetry,2 and the recently developed Rarebit microdot perimetry.3 With regard to best-corrected VA, 60% correctly identified letters was set as the cut-off.
Results
There was a significant correlation between birth weight deviation and the Rarebit hit rate (p = 0.009), but not with FDT indices. The mean hit rate was significantly lower in the IUGR group compared to the control group (p = 0.01).
Conclusion
These data indicate that IUGR is associated with slightly impaired visual function, which can be detected using Rarebit, but not FDT perimetry.
