Table 3

Number of patients diagnosed because of additional reasons.

	Reason for neuroimaging	Number of patients (% of study group)	Clinically significant result (% of patients examined for this reason)	Statistical analysis; ANOVA with Kruskal-Wallis test as a post hoc
1	Unilateral normal-tension glaucoma	72 (57.1%)	5 (6.9%)	1 vs. 7,; 5 vs. 7,; 6 vs.7,
2	The damage in the visual field inconsistent with optic disc appearance	9 (7.1%)	2 (22.2%)
3	Fast visual field progression (1.5 dB per year or more) assessed according to at least 3 reliable visual field results	5 (4.0%)	2 (40%)
4	Worsening of visual acuity of at least 2 lines in the Snellen chart connected neither with lens nor retinal pathology	4 (3.1%)	2 (50%)
5	Optic disc excavation accompanied by pallor	11 (8.7%)	2 (18.1%)
6	Patients diagnosed under the age of 50	23 (18.2%)	0 (0%)
7	Scotoma restricted by a vertical line	7 (5.5%)	5 (71.4%)
