Abstract

INTRODUCTION. The purpose of this clinical non-interventional cross-sectional study was to evaluate the role of apolipoprotein E (ApoE) gene alleles (e2, e3, e4) in the determination of optic disc size.

MATERIALS AND METHODS. In 32 normal controls, 54 patients with ocular hypertension (OHT), and 96 patients with primary open-angle the optic disc size was determined by planimetry using 15° colour stereo photographs. In all individuals ApoE genotyping was performed.

RESULTS. The size of the optic disc was significantly different between subjects with e3e2, e3e3, and e4e3 allele (Kruskal-Wallis-test, Chi-Square: 6.95, p = 0.031; 2.39, 2.77, and 2.78 mm2, respectively).

CONCLUSIONS. The results suggest that ApoE gene alleles are associated with optic disc size. ApoE may act as a modulator gene for optic disc morphogenesis.
