Morning Glory Syndrome

ABSTRACT

Recently we have experienced two cases of the morning glory syndrome which is an uncommon congenital anomaly of optic nerve head. Visual evoked potentials and fluorescein angiographic findings are described. The visual evoked potentials elicited with bright flashes and patterns revealed delayed latencies and subnormal amplitudes. The amplitude of the traces probably depends on the severity of the involvement of the optic nerve. Also, the possible macular abnormalities and the strabismic or anisometropic amblyopia developing in morning glory syndrome may contribute to the abnormal finding of visual evoked potentials.
