Foveal attachment status in primary RRD of different extent secondary to a 12 o’clock break. The vertical distance between the trough of the RRD and the visual axis when the posterior extent of the RRD is at the fovea for an emmetropic eye (a) and a − 10 dioptres myopic eye (c) in a mathematical model. The posterior extent of the RRD when the visual axis makes a tangent to trough of the RRD for an emmetropic eye (b) and a − 10 dioptres myopic eye (d) in a mathematical model
