INTRODUCTION Pseudo-Foster Kennedy Syndrome is described as unilateral optic disc swelling with contralateral optic atrophy in the absence of an intracranial mass causing compression of the optic nerve. This occurs typically due to bilateral sequential optic neuritis or ischaemic optic neuropathy. CASE PRESENTATION We describe a case of pseudo-Foster Kennedy Syndrome in a two year old boy wit...
A 26-year-old man, a 19-year-old man, and a 55-year-old man had bilateral optic nerve hypoplasia. They all had normal vision, but considerable defects in the inferior segments of the visual fields.
In patients with foveal hypoplasia, anterior segment dysgenesis and an absence of systemic findings, consider a recently described syndrome of foveal hypoplasia, optic nerve decussation defects and anterior segment dysgenesis (FHONDA) in the differential diagnosis.
Congenital absence of the optic nerve in man is a very rare anomaly (Duke-Elder, I963, I964). In true cases the optic disc, optic nerve fibres, and central retinal blood vessels are absent on ophthalmoscopic examination. Hypoplasia of the optic nerve, which is also rare, occurs when some or all of the nerve fibres fail to develop and reach the disc. The condition may be unilateral or bilateral,...
A case of a 14-year-old boy with optic hypoplasia and pituitary dwarfism was presented. Eye Examination showed typical hypoplasia of the left optic nerve and mild hypoplasia of the right optic nerve. Except for dwarfism and nystagmus, the appearance of the patient was not unusual. Computed tomography revealed an enlargement of the suprachiasmatic cistern, and the presence of the septum pellucid...
Septo-optic dysplasia (SOD) or Morsier syndrome is a rare congenital malformation of infantile neurodevelopment with systemic anatomical and functional involvement. It characterized by optic nerve hypoplasia, midline brain malformation, hypothalamic-pituitary axis hypoplasia. The spectrum clinical manifestations very wide, from ophthalmological problems to endocrinological disorders that determ...
