摘要:

28 patients treated with thioridazine (TZ) were examined by electroretinography (ERG). The most characteristic feature was a decrease in amplitudes of the oscillatory potentials O2, O3 and O4. A significant correlation was observed between the daily dosage of TZ and the diminished amplitude as well as the delayed peak time of the O2 wavelet. When a dose of 400 mg/day of TZ was administered during a short time, similar ERG changes were induced.

摘要:

5 cases of orbital pseudotumour are presented in which other general or local pathology is excluded. The characteristics of the pictures given in the CT were examined and treatment and evolution are discussed. In 2 of the cases biopsies were performed. We consider that the orbital pseudotumour is in most of the cases a primary orbital myositis. The degree of involvement of the adjacent orbital structures depends on its intensity.

摘要:

We report the clinical symptoms and the course of a case that showed the typical findings of a meningioma of the optic nerve sheath, characterized by visual disturbances, progressive visual field defect, proptosis, secondary atrophy of the optic disc, and shunt vessels between retinal and choroidal circulation. The shunt vessel which was demonstrated in this case by fluorescein angiography is identical with the optociliary vein reported in the literature. Fluorograms also revealed peculiar vessels at the margin of the optic disc, which have not been described in association with this tumor. CT scanning and roentgenograms of the optic canal proved useful as diagnostic tools for this tumor. The tumor was removed through a frontotemporal craniotomy, preserving the optic nerve. The histopathological diagnosis was meningothelial meningioma.

摘要:

Chiasmal region tumor-caused apoplexy it not uncommon. As its clinical picture varies and is complicated, early diagnosis is usually difficult. 7 cases are reported with marked visual loss, the presenting symptom. Visual fields all revealed definite chiasmal lesions and were indications for neurosurgery. Postoperative results were encouraging. The important symptoms and signs of this apoplexy are: abrupt severe headache, nausea, vomiting and even meningeal irritation, loss of visual function, ocular palsy and symptoms caused by the tumor itself. These symptoms may be mild or severe and may improve and then relapse and may appear simultaneously or one after the other. Onset is usually abrupt and the disease may subside gradually or end in death. Visual field examination is very important to make a correct diagnosis. In many reports the diagnosis is made only at operation or autopsy.

摘要:

A 56-year-old patient with histopathologically established myotonic dystrophy is described. Gross pathological examination of the eyes revealed cataracts and peripheral retinal dystrophy as described previously. Lacy vacuolization of the pigment epithelium of the iris and vacuolization of the nonpigmentary ciliary epithelium were also found. These latter findings have, to our knowledge, not been hereto described in the literature.

摘要:

A preselected population of 96 patients (67 glaucomas, 29 ocular hypertensions) were followed for an average period of 30 months. Timolol eye drops were administered either alone, in dosage strengths of 0.25 or 0.5% or in combination with other antiglaucoma drugs. 9 patients were lost to follow-up after a mean treatment duration of 15.3 months; glaucoma had been stabilized in all of them. 10 patients had unsatisfactory intraocular pressure control and 7 had to undergo trabeculectomy (9 of these 10 patients had campimetric glaucoma at the beginning of the study), whereas 76 patients had satisfactory intraocular pressure control and, in the majority, stabilization of glaucoma had been obtained. In 77% of this preselected population glaucoma was stabilized over a period of 3 years (i.e. close to two thirds of those starting treatment, 70% of which had campimetric glaucoma).

摘要:

The location of the corneal reflex (Purkinje’s first image) produced by an electronic flash was studied at various degrees of ocular rotation both in adduction and abduction. A statistical analysis of the results showed a good correlation between the decentration of the corneal reflex and the degrees of ocular rotation. The results thus obtained give an experimental basis to the clinical use of the so-called Hirschberg test for measuring the strabismus angle.
