Abstract

We evaluated the relationship between myopic crescent, refractive error and axial length in Chinese eyes. Fundus photographs, axial lengths and subjective refraction were assessed for 60 subjects. Photographs were analysed to classify myopic crescents according to type and location; crescent size was calculated as a fraction of horizontal optic disc diameter. Crescent diameter increases with increasing axial length and more myopic refraction when data for all eyes are included. Eyes with crescents have a greater axial length and more myopic refraction than eyes without crescents. When only eyes with crescents are considered, there is no correlation between crescent diameter or position with axial length or refractive error.
