In a young woman with an anomaly of the ocular motility evoking Brown's syndrome, an insertion anomaly of the superior oblique muscle, situated in the superior nasal quadrant 10 mm of the limbus, was found during operation. A stair-like tenotomy restored an almost normal motility.
A 24-year-old woman sustained bilateral ocular lesions due to projection of mercury into the eyes during an explosion in a chemical laboratory. A lamellar keratectomy was performed on the right eye four hours after the accident, and 12 days later, the same procedure was performed of the left eye. Studies by light and electron microscopy were done on both specimens. The essential findings were total loss of epithelium, necrosis of keratocytes, absence of inflammatory reaction, and absence of superficial stromal repair in the specimen that was obtained 12 days after the accident. These findings indirectly confirm the importance of epithelium and normally vascularized conjunctiva in healing wounds of the cornea.
Two cases of tumours - a pleomorphic poorly differentiated malignant neoplasm and a juvenile angiofibroma - involving the orbit and extending to the base of the skull are reported. In both cases computerized tomography showed with great precision the localization and the extension of the tumours.

This paper relates the case of a 54-year-old woman with spontaneous annular detachment of the chorioretina in the right eye. Through examination and evolution confirm that it is an "uveal effusion", most probably in relation with choroïdal circulatory troubles and an affection of the pigment epithelium.

A study is presented of three patients suffering from internuclear ophthalmoplegia without diplopia. The components of the nystagmus and the dysmetry of the oculomotor changes, as well as the difference in the respective speeds during abduction and adduction toward the side opposite to the lesion were recorded. A dysmetric component was found in the saccadic low amplitude movements (reading movements).

The treatment of retinal thrombosis is an unresolved problem, mainly because of the numerous factors which participate in their formation; modifications in the walls of veins and arteries, external compressions, changes in the blood count--particularly of the platelets--slowing down of the blood flow, increase in blood viscosity etc. No drug provides constant results. Some widely employed drugs such as vasodilators may be useless or even contra-indicated. Emphasis is placed on anti-coagulants, fibrinolytics, antiaggregating agents and methods of lowering blood viscosity. Their action is difficult to test objectively. Some do appear to be useful, especially in cases of central vein thrombosis. Thrombi of branches of the central vein are apparently inacessible to medical therapy, but occasionally improvement is seen after laser coagulation. This seems to apply also to hemorrhagic glaucoma secondary to retinal obstruction.

The authors present the case of an 11-year-old child with a slowly progressive tumoral invasion resulting in bilateral nasal obstruction, massive facial deformation, and an exophthalmos of the left eye. There was no impairment of the child's general health. The histological investigation revealed the presence of Mikulicz' cells and von Frisch's bacilli. The resultant diagnosis was rhinoscleroma.
