The heritability of optic disc shape

点击翻译按钮获取中文摘要

Evaluation of the optic nerve head (optic disc) is important in the diagnosis of various eye diseases, including glaucoma. The influence of genetics on the shape of the optic disc is not well understood because shape is difficult to measure. Using a novel method of shape analysis, this study will examine optic disc shape in populations of Australian twins and individuals with optic nerve disease. It will contribute to the genetic understanding of the optic nerve head and related disorders.
