- The term communicating exophthalmos is suggested for a condition where manual retropulsion of one eye results in proptosis of the other eye. This sign was observed in a patient with bilateral pulsating exophthalmos. The pulsating exophthalmos was ascribed to orbital roof defects in combination with post-traumatic hydrocephalus. It was controlled by a shunting procedure.

Drusen in the optic nerve head. Verification by computerized tomography.

- Five patients with a clinical diagnosis of buried or exposed drusen of the optic nerve head were examined by computerized tomography (CT). The relative x-ray absorption within their nerve heads was significantly larger than in controls, reflecting the high calcium content of drusen. Computerized tomography, and particularly high-definition CT, therefore merits consideration in the investigation of disc swelling.

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.

Spectrum of optic nerve hypoplasia.
- 1978

Ingår i: The British journal of ophthalmology. - 0007-1161. ; 62:1, s. 7-15

Tidskriftsartikel (refereegranskat)abstract
- Optic nerve hypoplasia is a non-progressive condition characterised by subnormal vision and a subnormal number of optic nerve axons. It may be unilateral or bilateral, isolated or combined with other defects. Analysis of fundus photographs from a series of 7 patients with a stationary abnormality of different degrees showed that the functional defects could be closely correlated with defects in the retinal nerve fibre layer. Our observations show that the condition has a wide range of both functional and anatomical defects and that a subnormal diameter of the optic disc is not a requisite for the diagnosis. Presumably, there is also a wide variety of causes, not only a primary failure of development of retinal ganglion cells. We suggest that optic nerve hypoplasia can be viewed as a non-specific manifestation of damage to the visual system, sustained any time before its full development.
