Table 2.

Percent visualization of the features of the posterior vitreous and vitreoretinal interface in healthy non-diabetic control eyes, diabetic eyes without retinopathy and diabetic eyes with different stages of retinopathy using vitreous enhanced three-dimensional swept-source optical coherence tomography imaging. n represents the number of eyes. p values represent the results of one-way analysis of variance. Significant p values are in bold.
