Choroidal rupture and optic atrophy.

Choroidal rupture and optic atrophy.

The association between post-traumatic optic disc pallor and traumatic choroidal rupture is poorly understood. To further define this relationship, nine cases of indirect traumatic choroidal rupture and post-traumatic optic disc pallor were compared with cases of indirect choroidal rupture without disc pallor in terms of severity of ocular injury, fundus findings, and visual outcome. The type a...

Gyrate atrophy and choroidal neovascularization.

Optic Atrophy.

BASIC CONSIDERATIONS Optic atrophy is a misleading term which, embedded by tradition and usage, resists precise definition. It is used when there is excessive pallor of the optic disc and is thus a physical sign and not a diagnosis. Since there are many causes of optic pallor, the term is usually reserved for those cases in which there is associated visual defect, either of fields or acuity, in...

Sectorial optic atrophy and homonymous, horizontal sectoranopia: a lateral choroidal artery syndrome?

Two patients with sectorial optic atrophy and homonymous, horizontal sectoranopia are described. Neuroradiological investigations localised the visual pathway lesion to the lateral geniculate body. The peculiar nature of the field defect and the optic atrophy appeared explicable in terms of ischaemia in the territory of the lateral choroidal artery.

Quadruple sectoranopia and sectorial optic atrophy: a syndrome of the distal anterior choroidal artery.

Loss of upper and lower homonymous sectors in the visual field, and wasting of corresponding sectors in the retinal nerve fibre layer, followed ligation of the distal part of the anterior choroidal artery in a patient with a meningioma of the velum interpositum. Clinical and radiological evidence indicated that the visual pathway was damaged within that part of the lateral geniculate body that ...
