[Neurinoma of the oculomotor nerves. Apropos of 2 cases]. / Neurinomes des nerfs oculomoteurs. A propos de deux observations.

The authors report two cases of neurinomas of the oculomotor nerves: one neurinoma of the oculomotor nerve and one of the abducens nerve. The study of 30 cases in the previous literature points out the major striking features of these tumors. Both headaches and oculo-motor palsies are the most regular clinical features. They are not typically suggestive. Therefore the diagnosis is difficult among all the tumors of cavernous sinus and surrounding structures. C.T. scan and M.R.I. with the clinical history should readily allow pre-operative diagnosis. These data are insufficient to distinguish the affected nerve. The surgical treatment is not always complete due to the tumor infiltration into the cavernous sinus.

[Submacular neovascular membrane and drusen of the optic disk]. / Membrane néovasculaire sous-maculaire et drusen de la papille.

A case of unilateral serous hemorrhagic maculopathy with a very acute course is reported in an eight year old girl fluorescein angiography revealed the presence of a subretinal neovascular membrane extending from the inferotemporal part of the disc to the macula; CT scan identified calcified drusen of the optic disc. Ophthalmoscopy and angiography one year later showed a glial macular scar, absence of hemorrhage and serous detachment. Visual acuity was reduced to counting fingers. This unusual type of maculopathy combining optic disc drusen and a neovascular membrane contradicts the classically benign prognosis of optic disc drusen.
