[Remanent efficiency of timolol in ocular hypertension (author's transl)]

In four ocular hypertensive patients (seven eyes) the lowering of intraocular pressure to a normal level persisted over a period of several months after gradual cessation of topical Timolol therapy. This remanent efficiency ("after-effect") could be used in treating ocular hypertension in order to prevent glaucoma damage.

[Massive orbital osteolysis by a chordoma. Report of a case and review of the litterature (author's transl)]

Clinical, radiological and anatomical description of sellar chordoma giving, on a sixty seven years old man, an unusually large tumoral exophthalmos, a massive orbito-sphenoidal osteolysis and a chiasmatic syndroma. Discussion stresses the topographic data of chordoma in connection with the embryonal chordal cell rests. Patterns of evolution and neuro-ophthalmologic symptoms of cephalic chordoma are studied with the literature facts. Morphologic criteria, specifical ones and those differential diagnosis, are exactly scheduled.

[Aneurysmal cyst of the orbit (author's transl)]

A child of 11 years of age was found to have an aneurysmal cyst of the orbit. This is an extremely rare cause for tumoral exophthalmia in children and the localization in this region is also very unusual. Only 14 cases are reported in the published literature. The main differences in relation to those occurring in the long bones and vertebrae are the constant absence of pain and the almost exclusively osteolytic radiological appearance.

[Osteogenic aneurysmal orbital cysts]

The orbital form of this osseous tumor-like dystrophy is quite rare. The illustrated description of a new case is reported and the 13 cases of the literature reviewed. The main clinical and radiological data as well as the different treatments are commented upon. The anatomo-pathologic discussion focuses on the morphological aspects, hypotheses on the pathogenesis and differential microscopic features of the lesion as compared to other osseous lesions of the orbital bones.
