POAG = primary open angle glaucoma; NTG = normal tension glaucoma; PXF = pseudoexfoliation syndrome; PDS = pigment dispersion syndrome; ns = no significant differences.
↵Pearson’s χ2 test for categorical data; analysis of variance (ANOVA) for continuous data with Duncan’s correction for multiple comparisons (p<0.05).
↵There were more males in the myopic glaucoma group in comparison with the other groups.
↵There were more females in the focal ischaemic glaucoma group in comparison with the other groups.
↵Patients with myopic glaucoma were younger than patients with each of the other types of glaucomatous discs.
Patients with senile sclerotic glaucoma were older than patients with each of the other types of glaucomatous discs.
↵There were more Asian (Oriental) patients in the myopic glaucoma group in comparison with the other groups.
↵Both the highest recorded IOP and the mean of the highest three recorded IOPs were greater in the group of eyes with glaucoma associated with generalised enlargement of the optic disc cup in comparison with each of the other groups.
↵The degree of myopia in the group of eyes with myopic glaucoma was greater in comparison with each of the other groups.
$The visual field mean deviation in eyes with myopic glaucoma was greater than in eyes with generalised cup enlargement glaucoma.
The visual field mean deviation in eyes with focal ischaemic glaucoma was greater than in eyes with senile sclerotic or generalised cup enlargement glaucoma.
