DVC deep vascular complex, EA explant area, VA vessels area, VPA vessels percentage area, TNJ total number of junctions, JD junctions density, TVL total vessels length, AVL average vessels length, TNEP total number of end points, ML mean lacunarity
This table shows median and interquartile ranges for each parameter (25th and 75th percentile). P values and percentages of change are presented one week after phacoemulsification
Friedman ANOVA test, significant difference (bold values) was found for values with P < 0.05
