Study Population

Tertiary hospital

You may qualify if:

  • From December 2024 to May 2025, preterm infants (gestational age \<37 weeks) or low birth weight infants (birth weight \<2500 g) who receive their first ROP screening at Xinhua Hospital or partner institutions will be included.

You may not qualify if:

  • Death before the first screening;
  • Death or loss to follow-up before complete retinal vascularization;
  • Presence of other diseases causing incomplete retinal vascularization, such as familial exudative vitreoretinopathy, incontinentia pigmenti, or Coats disease;
  • Coexisting conditions affecting the classification or staging of ROP, such as corneal opacity, congenital cataract, persistent fetal vasculature, retinoblastoma, anophthalmia, Terson syndrome, or other ocular infections or diseases;
  • Poor systemic condition preventing fundus examination;
  • History of ocular trauma or surgery (excluding treatments for ROP);
  • Poor-quality fundus images;
