Comparison of age, blood pressures, body mass index, and intraocular pressure
| Type of RVO | No | Mean (SD) | Range | F ratio | |
|---|---|---|---|---|---|
| The mean, standard deviation (SD), and range of age, systolic and diastolic blood pressures, body mass index, and intraocular pressure (IOP) of the five types of RVO. The overall multivariate analysis of variance for the five parameters was highly significant (p<0.0001). The F ratios for each parameter show that the differences in the mean age and IOP account for most of this statistical trend (NS-RVO excluded from analysis). No = number of cases; AV-RVO, arteriovenous crossing RVO; OC-RVO, optic cup RVO; NONHS-RVO, optic nerve sited RVO without ONHS; ONHS-RVO, optic nerve sited RVO with ONHS; NS-RVO, “No site” RVO. | |||||
