Glaucoma parameters and cognitive impairment
| Glaucoma parameter (mean (SD)) | Cognitive stratification | P value | |
| Impaired (<11/22) | Normal (≥11/22) | ||
| Total number (n) | 29 | 261 | |
| Highest measured IOP (mm Hg) | 21.9 (8.7) | 25.5 (9.4) | 0.16 |
| LogMAR BCVA | 0.36 (0.31) | 0.29 (0.40) | 0.19 |
| VCDR worst eye | 0.86 (0.09) | 0.83 (0.12) | 0.55 |
| Mean deviation worst eye (dB) | −14.4 (9.3) | −12.9 (9.2) | 0.40 |
| CCT average (µm) | 519.2 (36.7) | 525.6 (39.1) | 0.57 |
P values were determined with linear regression using age as a covariate.
LogMAR BCVA, logarithm of the minimal angle of resolution best central visual acuity; CCT, central corneal thickness; IOP, intraocular pressure; VCDR, vertical cup-to-disc ratio.
