ABSTRACT
PURPOSE:
To study macular topography and contrast sensitivity (CS) in diabetic and nondiabetic women during pregnancy and post partum.METHODS:
A prospective study of 46 pregnant women with insulin-dependent diabetes and 11 nondiabetic pregnant controls. Macular surface topography was analyzed by Heidelberg Retinal Tomograph. Volume above the reference plane (VARP) was measured with 1.0-, 1.5-, 2.0-, and 3.0-mm-diameter circles. CS was measured with the Vistech 6500 Contrast Test System.RESULTS:
The diabetic women had greater VARP than the controls measured with the 1.5-mm diameter circle. In diabetic women, the mean VARP was 0.084+/-0.064 mm(3) (mean +/- SD) in the first trimester, 0.080 +/- 0.056 mm(3) in the third trimester, and 0.087 +/- 0.067 mm(3) 3 months post partum compared with the values of 0.069+/-0.043, 0.054+/-0.024, and 0.036+/-0.020 mm(3) in the controls ( P=0.036 between groups). In diabetic women requiring laser treatment, the difference from controls was more significant ( P<0.001). CS at 3 cpd and 6.0 cpd was lower in diabetic women than in controls throughout pregnancy and post partum ( P=0.012 and P=0.043). A statistically significant negative correlation appeared between macular topography and CS during the third trimester; between cpd 6 and VARP 1.5 mm ( r=-0.471, P=0.001), and between cpd 6 and VARP 2.0 mm ( r=-0.446, P=0.002).CONCLUSIONS:
In the diabetic women, especially in those with clear progression of retinopathy during pregnancy and post-partum, the macula seemed to be slightly more elevated than in the controls, and CS was lower at mid-range spatial frequencies. CS loss in the diabetic women correlated with macular elevation during the third trimester.
