Top-Ten of the South African Glaucoma Society: Pearls from the Guest Speaker Ivan Goldberg
May 21-23, 2004, Drakensberg, South Africa

- IOP measurement is confounded by CCT, thinner cornea result in false low IOP measurement, thicker corneas in false high measurements.
- Ignore IOP at diagnosis, OD appearance, RNFL is more important. Low IOP or normal IOP could be early glaucoma.
- Newly diagnosed glaucoma as well as established treated glaucoma patients should be regularly adjusted to target pressures following the information of visual field assessments
- Disc size is different in hyperopes and myopes; watch for tilted disc in myopes.
- CCT under 555 micron is a higher risk factor than c/d ratio of the optic disc.
- Diurnal fluctuation of IOP is a 6:1 risk factor of rate of progression.
- Switching anti-glaucoma drugs is often better than adding another drug.
- On the long run drugs increasing outflow are preferable.
- Glaucoma patients on treatment and all newly diagnosed glaucoma patients should at least once have a CCT measurement to establish the CCT risk factor.
- It seems that adding CAI to prostaglandins lowers IOP more than adding beta-blockers or α2-agonist drugs.
