[Onset of Leber's hereditary optic neuropathy in association with borreliosis].

Introduction: The diagnosis of Lyme disease in the presence of an acute optical neuritis always raises a difficult diagnostic problem. We present a case of Lyme-associated Leber's hereditary optic neuropathy (LHON).

Observation: A 17-year-old Eurasian young man presented with left-eye visual impairment for 1 month.

[Long-term effects of iterative diving on visual field, color vision and contrast sensitivity in professional divers].

Purpose: To assess long-term functional effects of iterative diving, we studied visual field, color vision, and contrast sensitivity in 21 French Navy professional divers and 21 controls.

Patients And Methods: This retrospective study investigated a population of 21 divers and 21 controls. All subjects were male.

[Orbital myositis associated with ulcerative colitis].

We report a rare case of a 32-year-old Caucasian man who presented with a 2-month history of progressive proptosis in his left eye with no visual impairment nor diplopia. He had suffered from ulcerative colitis for 3 years before presentation. Computed tomography and magnetic resonance imaging scans demonstrated mild proptosis and isolated enlargement of the left superior rectus muscle.

[Abducens nerve palsy in spontaneous intracranial hypotension].

Described by Schaltenbrand (1940), spontaneous intracranial hypotension is an unusual syndrome, sometimes revealed by an abducens nerve palsy motivating the patient to consult emergency ophthalmology services. The Authors report the case of a 50-Year-old Turkish woman who presented with diplopia due to a left abducens nerve palsy. These symptoms were associated with headache and nausea.

[Indications for the use of an epidural blood patch in the treatment of spontaneous intracranial hypotension].

We report a patient with spontaneous intracranial hypotension treated with an epidural blood patch (EBP) and discuss the indication of this procedure in the treatment of this syndrome. Once diagnosis has been established (symptoms, CSF pressure, MRI), we propose to wait no more than a week, when simple treatment options have failed, before proceeding to an EBP. We inject a minimum of 20 ml, until the appearance of pain while injecting, of autologous blood in the L3-L4 epidural space.
