Optical coherence tomography and angiography for the assessment of retinal microvasculature in retinopathy of prematurity patients: A systematic review and meta-analysis.

Random-effects meta-analysis in R software computed pooled mean differences (MD) with 95% confidence intervals and heterogeneity (I²).

Similar patterns emerged for foveal DCP vascular density (MDs: -7 to -8%, P < 0.001).

Parafoveal SCP vascular density was higher in term vs. treated groups (MDs: 3-4%, P < 0.001).

Laser-treated eyes had greater foveal thickness than regressed (MD: 35.5 µm, P < 0.001) and untreated retinopathy of prematurity (MD: 26.6 µm, P = 0.004).
