- A patient with a cystic craniopharyngioma below the right optic nerve had several recurrences requiring surgery. Finally the cyst was connected with a subcutaneous reservoir by means of a fine catheter. Symptoms of optic nerve compression recurred more than 50 times during the following year, and were relieved within seconds upon drainage of the reservoir. In each cycle, a drop in visual acuity preceded a measurable change in the visual field. The pattern of field changes was an increasingly severe, uniform depression. Optic nerve ischaemia induced by compression was probably the most important factor causing visual failure in this case.

- 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 is served by the anterior choroidal artery.

Sarcoid-like disorder of the intracranial optic nerve.

-
Tidskriftsartikel (refereegranskat)abstract
- Two cases with a sarcoid-like disorder apparently restricted to the intracranial optic nerve and the adjacent dura mater are described, doublilng the number of reported cases. In both instances there were unilateral visual loss and unusual radiographic changes in the optic canal area. Biopsy samples showed localised infiltration of tissues with non-caseating tubercles containing epithelioid and multinucleated giant cells.

Sectorial optic atrophy and homonymous, horizontal sectoranopia: a lateral choroidal artery syndrome?
- 1978
-
Ingår i: Journal of neurology, neurosurgery, and psychiatry. - 0022-3050. ; 41:4, s. 374-80
-
Tidskriftsartikel (refereegranskat)abstract
- 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.
