[Homolateral episcleral metastasis or surgical seeding of a proton-irradiated ciliary body melanoma?].

In an eye with a proton beam-irradiated malignant melanoma of the ciliary body a second melanoma appeared episclerally on the opposite side of the globe. Microscopic examination did not show any connection to the primary tumor. The different possibilities of pathogenesis (bloodborn metastasis to the same globe, episcleral metastasis by conjunctival lymphatics, surgical dissemination due to the suturing of tantalum marks around the primary tumor) are discussed. The ciliary melanoma has spread over the iris despite the irradiation, probably as a result of insufficient irradiation of its anterior border. The results of histologic examination of the partially necrotic, partially viable irradiated tumor are considered with regard to the conservative tumor therapy administered.

Optico-cerebral syndrome: simultaneous hemodynamic infarction of optic nerve and brain.

Three (0.5%) of 612 patients with an acute ischemic stroke in the carotid territory also had ipsilateral optic nerve infarction. They had unilateral or bilateral internal carotid artery occlusion and reversed flow in the ophthalmic artery. Hemodynamic infarction was suggested by triggering by a drop in blood pressure, decreased ophthalmic artery flow and perfusion pressure, and cerebral infarction in a watershed area. The "optico-cerebral syndrome" suggests internal carotid artery occlusion with hemodynamic disturbances. In carotid disease, monocular blindness may be due to an optic nerve lesion sparing the retina.

[Association of an epithelial dermoid with alopecia and a sebaceous verrucose nevus: hologynic hereditary malformations].

The association of alopecia with a sebaceous verrucose nevus and an epibulbar lipodermoid is a rare condition (8 cases reported in the literature). Only girls suffer from this disease; this suggests a hologynic heredity, as in the case of Aicardi's syndrome. The authors present a new observation of a 7-year-old girl who exhibits all the characteristics of this new syndrome.

[Tumors and pseudotumors of the pigment epithelium].

Tumors and tumor-like lesions of the pigment epithelium of the iris, ciliary body, and retina are discussed with special emphasis on definitions and the various elements of help in the differential diagnosis. One of these lesions, hypertrophy of the retinal pigment epithelium, is classically described as non-progressive. However, we report here 4 cases with documented progression of various forms. The etiology and physiopathologic considerations are discussed. Although most tumors and pseudotumors of the ocular pigment epithelium are benign, malignant forms and various non-malignant, but progressive types can occur.

[International survey on the incidence of severe or fatal complications which may occur during fluorescein angiography].

Serious or fatal accidents during fluorescein angiography were assessed by an international survey involving answers from 260 clinics in 30 different countries in respect of 594, 687 angiographies. Incidence of fatal accidents was one case per 49,557 angiographies, and of serious accidents, one case per 18,020 angiographies. The total number of accidents reported was 45 cases, equal to one case per 13,215 angiographies. Age, general health of the patients, and the experience of the different clinics who perform this examination, seem to influence the occurrence and the seriousness of these accidents.

A new mobile armrest.

We have developed a weight-and-pulley armrest for surgeons to use during ocular microsurgery. The armrest is mobile, sterilizable, and allows the weight stress on the forearm to be regulated.

Ocular and orbital complications after sclerosing injections in a case of a frontal cutaneous angioma.

A baby is treated for frontal cutaneous angioma by two sclerosing injections, the second injection giving rise to severe complications and life-long sequelae: total amaurosis of the right eye with eventual bulbar phthisis, sectorial iris necrosis and cataract formation, as well as ugly sunken cutaneous scarring of the right upper eye-lid, forehead and scalp. It is the only case we know of, where such complications occurred after craniofacial angioma treatment by sclerosing injections.

[Aniridia in a family characterized by low penetration].

Familial aniridia is an hereditary condition with dominant transmission. The frequency of associated lesions appears to indicate that absence of the iris is only the primary sign of an anomaly of development of the entire eye, derivatives of the ectoderm being predominantly affected. The authors examined the presence of familial anridia through 4 generations, characterized by low penetration and cataract predominantly of the right eye.
