Contralateral occipital depression related to obstetric forceps injury to the eye.
Obstetric forceps pressure strong enough to leave a periorbital depression and corneal injury would probably be severe enough to leave an occipital depression from the opposite forceps blade. The presence of a depression at the correct occipital position would support the diagnosis of forceps injury when the birth history is unknown and the cornea has decompensated enough to make observation of the Descemet's membrane scrolls difficult. We studied six patients with known or suspected obstetric forceps injury to the cornea. Complete ocular examinations included examination for periorbital forceps depressions and posterior skull depressions 180 degrees from the affected cornea (which correlates with the opposite blade of the forceps). All of the patients with Descemet's scrolls had posterior skull depressions. This method of palpation for a contralateral skull depression may assist in the diagnosis of forceps-induced corneal decompensation.
