  • Title: [Choroidal detachment associated with spontaneous carotid cavernous fistula].
    Author: Yamada M, Ikeda N, Mimura O, Maeda Y.
    Journal: Nippon Ganka Gakkai Zasshi; 1991 Jul; 95(7):704-9. PubMed ID: 1927752.
    Abstract:
    A rare case is presented in which an 87-year-old woman with choroidal detachment was subsequently found to have an atypical carotid cavernous fistula (CCF). In this case, the intraocular pressure of the affected eye was higher than that of the contralateral eye. However, tonography showed no increased ocular pulse (amplitude of Schioetz reading) of the affected eye, which is characteristic of CCF. Choroidal detachment accompanied with CCF is thought to be a result of severe choroidal hemostasis and transudation caused by increased episcleral venous pressure. Furthermore, the enlarged perichoroidal space due to choroidal detachment reduced the ocular pulse of the affected eye. This combination may not be as rare as it has been previously reported. Attention to these symptoms can provide clues to the elucidation of the pathogenesis of choroidal detachment.
