[Coordimetric screens. Critique and possible improvements].

The visual screen tests are too short. They have the disadvantage to be square and to have square pattern with variable angular values. The authors suggest to use a 2.

[Eyelid motor impersistence].

Eyelid motor impersistence is the impossibility shown by some people to maintain voluntary lid closure for a long period. This disorder is not exceptional, and the authors have seen fifteen cases over a short period of time. The phenomenon represents a form of apraxia, and occurs only when the minor hemisphere is damaged with a lesion of the parietal lobe.

[Diagnostic and therapeutic problems in brucellosis uveitis (author's transl)].

The diagnosis of ocular brucellosis relies on the Witmer's ratio between ocular and seric specific antibodies. If the dosage in acqueous humor is not available a presumptive diagnosis is given by significative values of serologic tests (buffered antigene test, indirect immunofluorescence, passive hemagglutination test) and by the cell-immunity test (TIL and IML). Treatment must be local, symptomatic and general, with antibiotherapy associated with desensibilization.

[Selective paralysis of downward gaze with permanent conjugated upwards deviation : report of a new case (author's transl)].

Permanent upward conjugated ocular deviations are exceptional in conscious subjects : 8 cases only have been reported. They are always associated with a more or less selective paralysis of downward gaze. A further case is reported, with results of oculographic and computed tomography examinations.

[Trabeculitis and Besnier-Boeck-Schaumann disease (author's transl)].

The trabeculitis is a nodular infiltration of the trabeculae. His visualization is made after gonioscopy for hypertony or systematic examination of the angle. The alone etiology known is sarcoidosis and the treatment is corticosteroid.

[Enophthalmic orbital metastasis].

Some orbital metastases (16 cases in the literature and 2 personal cases) involve a histologically typical enophtalmos with profuse fibrous stroma. They arise after squirrhous carcinoma of the breast or plastic linitis of the stomach.

[A criticism of Lancaster's test and its variations (its inadequacies during the study of oculomotor paralyses) (author's transl)].

Lancaster's test has many technical inconveniences : Its interpretation is sometimes difficult or impossible. The information it gives is often incomplete. It is of no value in cases with binocular motor lesions.
