Table 3:

Percent accuracy, precision (relative standard deviation) and paired two tailed t-test (p-value) for noninvasive volume measures for suprachoroidal, subretinal, and intravitreal implants. P > 0.05 indicates no significant differences between the two types of measurements. Data are presented as mean SD for n=4–5 eyes. Key: SC- Suprachoroidal, SR- Subretinal, and IVT- Intravitreal, NE-Not estimated.
