Sensitivities, specificities, PPVs, and NPVs of various grades of posterior segment hemorrhage in predicting profound vision loss
| Posterior Segment Hemorrhage | Sensitivity (95% CI) | Specificity (95% CI) | PPV (95%CI) | NPV (95% CI) |
|---|---|---|---|---|
| PSH ≥ grade I | 98 (62/63) (91–100) | 64 (14/22) (41–83) | 89 (62/70) (19–95) | 93 (14/15) (68–100) |
| PSH ≥ grade II | 86 (54/63) (75–93) | 91 (20/22) (71–99) | 96 (54/56) (88–100) | 69 (20/29) (49–85) |
| PSH grade III | 78 (49/63) (65–87) | 100 (22/22) (85–100) | 100 (49/49) (93–100) | 61 (22/36) (43,77) |
Note:—PSH indicates posterior segment hemorrhage; NPV, negative predictive value.
