  1. Data are presented as means ± standard deviations where applicable.
  2. Analysable RP group: RP patients with analysable quality of the optical coherence tomography angiography images.
  3. RP = retinitis pigmentosa, ILM = internal limiting membrane, IPL = inner plexiform layer, ISe = inner segment ellipsoid band; RPE = retinal pigment epithelium.*P < 0.05, t-test.
