- Stuart Graham's work on objective testing of the visual field by
visual evoked potentials from random dot patterns to each of 58 points
extending on to 32 degrees nasally was independently reviewed by Ivan
Goldberg.
On comparison with Humphrey perimetry defects corresponded in 98 out of 100 cases with a 96% specificity. 21 cases showed a defect in the fellow eye which was normal on Humphrey perimetry but had suspect optic discs, suggesting a potential for earlier identification of defects than white on white perimetry.
- In unilateral pseudoexfoliation of the lens capsule (Pxf) Anne Brooks concluded that Pxf is usually associated with a high pressure with cupping and field loss. Central retinal vein occlusion occurred only in the affected eye in this series. This was presumably associated with either the common rise in intraocular pressure in the affected eye or was possibly associated with the Pxf process.
- Cataract surgery in glaucoma patients was discussed by Carlo Traverso who concluded phacoemulification in the procedure of choice for cataract in glaucoma.

In pigment dispersion syndrome Bill Gillies suggested a wide variation between patients in the effect of pigment dispersion on intraocular pressure and visual function. A considerable number of patients were normotensive. The clinical onset of the condition seemed later in women than in men.
