[Leber "plus" disease: optic neuropathy, parkinsonian syndrome and supranuclear ophthalmoplegia].

A 34-year-old right handed man presented with a bilateral subacute optical neuropathy associated with cervical dystonia, parkinsonism and supranuclear ophtalmoplegia. Magnetic resonance imaging showed in T2 increased intensity of signal in the dorsal mesencephalum and pons as well as in dorsal part of striata. The 3,460 mutation of mitochondrial DNA was found in a blood sample.

Room tilt illusion. A central otolith dysfunction.

Background: We report a sudden 90 degrees room tilt illusion (RTI) following vestibular stimulation in 3 patients with persistent skew deviation caused by a brain stem lesion. Room tilt illusion is a transient tilt perception of the visual surrounding, on its side or even upside down, that is often reported with brain stem lesions. Although its pathophysiologic cause is not well known, the RTI suggests an impairment of otolith pathways, as reported in skew deviation.

Ophthalmic results in patients with macroprolactinomas treated with a new prolactin inhibitor CV 205-502.

Macroprolactinomas are pituitary tumours which have been effectively treated medically since the introduction of bromocriptine. The visual function of 13 patients treated with a new prolactin (PRL) inhibitor CV 205-502 (Sandoz Basle), a potent and selective dopamine D2 receptor agonist, was evaluated. This is the first detailed ophthalmic report of the use of this drug in macroprolactinomas.

Idiopathic intracranial hypertension after ofloxacin treatment.

We report the occurrence of idiopathic intracranial hypertension in a patient treated with ofloxacin, a fluoroquinolone antimicrobial agent, for 16 months. The withdrawal of ofloxacin and acetazolamide therapy were followed by a complete recovery of visual function.

Homonymous horizontal sectoranopia: report of four cases.

Four cases of right homonymous horizontal sectoranopia are described. They were investigated with automatic static perimetry matched in three cases with Goldmann perimetry. In two cases--a wound of lateral sinus, a temporal surgically excised oligo-dendroglioma--neuroradiological investigations localised the visual pathways lesion to the optic radiations.

Pituitary adenomas: automatic static perimetry and Goldmann perimetry. A comparative study of 345 visual field charts.

In a series of 81 cases of pituitary adenoma 345 charts of visual field performed with static automatic perimetry (AP) on the Vision Monitor and Goldmann perimetry (GP) were compared. Generally both methods were equivalent in the detection of chiasmal compression. The charts were divided into two groups: (A) 208 charts and (B) 137 charts according to the number of isoptres investigated: two (V4, 112) or three (V4, 112, 12).

Effects of a new prolactin inhibitor, CV 205-502, in the treatment of human macroprolactinomas.

The effects of a new PRL inhibitor, CV 205-502 (CV), on human macroprolactinomas were studied in nine patients according to a prospective protocol. Five patients had undergone surgery leaving tumor remnants and persistent hyperprolactinemia. The four others were de novo patients, two of whom had received short term treatment with Parlodel.

Contrast sensitivity function and pituitary adenoma: a study of 40 cases.

The authors studied the contrast sensitivity function in 40 patients with pituitary adenoma. It seems to be a good index of compression of the visual pathway in this disease, but it lacks specificity and it cannot be used alone.

[Value of contrast sensitivity in neuro-ophthalmology. Main indications].

Contrast visual testing (CVT) is a psychovisual test newly used in the clinical study of neurovisual disorders. Using a micro E (Luer-Essilor) the authors present their technique and discuss the principal indications of CVT in neuro-ophthalmology.

[Spatial contrast sensitivity in multiple sclerosis].

Spatial contrast sensitivity was measured in 110 patients with multiple sclerosis (definite = 72, probable = 22, possible = 16) as part of a routine evaluation in a neuro-ophthalmological clinic. Results were compared with those of 37 normal controls matched for age. The test was abnormal in 71 p.

[Evaluation of the central visual field by the Friedmann Mark I analyzer and color vision in 85 patients with multiple sclerosis. Correlation with visual evoked potentials in 50 cases].

Analysis of the visual field using Friedmann's analyser Mark I and color study in 85 multiple sclerosis patients. Static perimetry of the central visual field and test batteries (Ishihara plates, 15 Hue Standard, 15 Hue of Lanthony) for acquired color vision defects were performed in 85 multiple sclerosis patients (61 definite, 12 probable, 12 possible cases). Results in patients were compared to data obtained in 53 control subjects matched for age.

[Reese's conjunctival melanosis. Two anatomicoclinical observations with ultrastructural study in one case].

Two cases of Reese's conjunctival melanosis are reported. Inflammatory signs revealed the presence of the lesion in a 58-year-old woman, examination demonstrating diffuse brown conjunctival, tarsal, and bulbar pigmentation in the right eye, raised above the surface at the sclerocorneal junction. Histology after exenteration demonstrated coexisting diffuse atypical melanocytic hyperplasia (precancerous melanosis), an intraepithelial melanoma (cancerous melanosis), and an invasive melanoma which was the object of an ultrastructural study.
