[Melanocytoma of the optic disc. Three case studies].

Purpose: Melanocytoma is a rare benign tumor that usually occurs as a pigmented lesion in the optic nerve head. It seems to be more frequently encountered in the Black population. We report three cases of melanocytoma observed in Martinique, where 90% of the population is of African origin.

[Optical involvement in multiple sclerosis. Results of a cross-sectional study with 57 patients from Martinique].

Introduction: The optical disease observed concurrent with multiple sclerosis is poorly known in blacks because of the rare occurrence of this pathology in the black population. The few studies currently available suggest more severe problems in black subjects than in Caucasians. Martinique has subjects who are genetically close or even identical but who acquired multiple sclerosis in two very different endemic areas: some in Martinique and others in France.

[Benign intracranial hypertension. Retrospective study of 20 cases].

Purpose: We conducted a retrospective study in 20 cases of idiopathic intracranial hypertension (IIH) referred to the ophthalmology out-patients department at the Centre Hospitalier Universitaire of Fort de France. The objectives were to characterize symptomatology, severity, disease course and to discuss treatment.

Methods: We performed a complete ophthalmological and neurological examination, calculated the body mass index (BMI) and evaluated visual field.

[Isolated blow out fracture of the medial wall of the orbit with medial rectus entrapment. Apropos of 3 cases].

We report three cases of isolated medial orbital wall blow out fracture with medial rectus entrapment. Few cases have been reported in the literature, predominantly in black people as in this paper. Predominance of this rare fracture in black population could be explained by an anatomic hypothesis based on racial origin.
