Optic nerve hypoplasia (ONH) is a congenital condition in which the optic nerve is underdeveloped (small). In addition, in some cases of ONH children will have a nystagmus, which is unusual eye movement. This often results in a small optic nerve. These may manifest as disordered temperature regulation, hyperphagia and obesity, and disrupted sleep-wake cycles. The ability of a child with ONH to produce vital hormones may also be affected.
