Magnetic resonance imaging of the head was normal. Intermittent intorsion of the right eye was noted on examination, consistent with superior oblique myokymia. She was initially treated with carbamazepine but stopped after becoming light-headed. The diagnosis and treatment of superior oblique myokymia are discussed.展开更多

He had normal extraocular motility and a 2 prism diopter right hypertropia that was comitant but could not be relieved with over lying prisms. Funduscopy revealed an epiretinal membrane within the macula on th e left more than the right. After his metamorphopsia worsened, and his visual ac uity decreased to 20/40 in the left eye, he underwent pars plana vitrectomy with removal of the epiretinal membrane and his diplopia resolved. Macular pathology including epiretinal membranes and choroidal neovascular membranes may rarely c ause binocular diplopia because of foveal displacement and rivalry between centr al and peripheral fusional mechanisms.展开更多

Ca se report. A 52 year old man who presented with right sided ptosis and ophtha lmoplegia was found to have an enhancing mass of the right orbital apex and cave rnous sinus extending into the temporal fossa on magnetic resonance imaging. Che st computed tomography revealed hilar adenopathy and a lesion of the right lower lobe of the lung. Bronchial washings and transbronchial needle biopsies of the lung were nondiagnostic. Computed tomography guided fineneedle aspiration of th e temporal fossa portion of the mass was performed. Biopsy of the mass showed ma lignant cells consistent with metastatic non small cell lung carcinoma. Compute d tomography guided fine needle aspiration can be useful in the diagnosis and management of some masses involving the cavernous sinus.展开更多
