- Vessel densities before and after silicone oil removal are described as mean ± SD
- Changes in vessel densities are described as mean (95% confidence interval)
- aDifference of change in vessel densities between affected and contralateral eyes was analyzed using mixed model analysis and presented as mean (95% confidence interval). The P value represents the main effect of SOR with changes in intraocular pressure and OCT angiography image quality score adjusted as covariates
