Comparison of mean deviation (MD) change and MD slope
| Before | 3 months | 6 months | 9 months | 12 months | P value | MD slope (dB/year) | |
|---|---|---|---|---|---|---|---|
| Operative eyes (dB) | −19.7 ± 5.6 | −19.6 ± 5.7 | −20.3 ± 5.4 | −19.8 ± 5.3 | −20.4 ± 5.1 | 0.194 | −0.26 ± 0.64# |
| Nonoperative eyes (dB) | −8.8 ± 8.0 | −10.2 ± 8.4 | −9.3 ± 8.3 | −9.8 ± 8.8 | −9.5 ± 8.4 | 0.011 | −0.65 ± 0.70# |
Notes: Values are mean ± standard deviation. P values were derived by ANOVA for repeated measures.

P = 0.047 (Mann-Whitney U-test).
