Mean Deviations, Cataract Density, and Visual Acuity Stratified by Glaucoma Severity.
| Parameter | Normal | PPG | Early PG | Moderate PG | Severe PG |
|---|---|---|---|---|---|
| VF_MD (dB) | −0.04 ± 0.79 | −0.51 ± 1.15 | −2.48 ± 1.17 | −8.55 ± 0.00 | −15.18 ± 1.65 |
| NFL_MD (dB) | −0.17 ± 0.55 | −0.85 ± 1.22 | −2.47 ± 1.87 | −5.00 ± 3.22 | −8.11 ± 4.25 |
| NFL_MD – VF_MD (dB) | −0.13 ± 0.88 | −0.34 ± 1.71 | 0.01 ± 2.08 | 3.54 ± 3.18 | 7.17 ± 2.68 |
| Cataract (0–4) | 0.59 ± 0.51 | 0.79 ± 0.55 | 0.89 ± 0.57 | 0.79 ± 0.36 | 0.81 ± 0.50 |
| BCVA (LogMAR) | −0.03 ± 0.07 | 0.01 ± 0.07 | 0.02 ± 0.06 | 0.00 ± 0.08 | 0.06 ± 0.07 |
Group mean ± standard deviation. The best-corrected visual acuity (BCVA) was analyzed in the form of the logarithm of minimum angle of resolution (logMAR). LogMAR values of 0, 0.1, and 0.2 are equivalent to Snellen acuity of 20/20, 20/25, and 20/32.
