The average of mean deviation of Humphrey field analysis in each stage of the two glaucoma groups
| Stage | NTG group | POAG group | p Value |
|---|---|---|---|
| NTG = normal tension glaucoma, POAG = primary open angle glaucoma. | |||
| Comparisons between groups were done using Student's t test. Data are reported as mean (SD). | |||
| Early stage | −2.42 (1.54) (n=22) | −2.59 (1.39) (n=21) | 0.706 |
| Moderately progressed stage | −9.42 (2.82) (n=23) | −10.02 (3.14) (n=17) | 0.530 |
| Progressed stage | −20.51 (4.72) (n=15) | −23.61 (4.88) (n=17) | 0.079 |
| Total | −9.62 (7.65) (n=60) | −11.38 (9.40) (n=55) | 0.271 |
