  • Purpose:

    To evaluate the impact of retinopathy of prematurity (ROP) on retinal and foveal microvasculature in children, using Optical Coherence Tomography Angiography (OCT-A).

  • Methods:

    An observational study involving 108 eyes from children aged 3-14 with a history of prematurity and ROP, both treated and untreated. OCT-A was performed, and data were analyzed for retinal and foveal changes.

  • Results:

    A reduction in the foveal avascular zone (FAZ) was found in 73% of ROP cases, with 93% exhibiting flat fovea. Treatment increased the risk of FAZ reduction and flat fovea. A negative correlation was observed between FAZ size and visual acuity.

  • Conclusions:

    ROP and its treatments significantly alter retinal microvasculature and foveal structure. OCT-A is an effective, non-invasive tool for detailed evaluation, offering crucial insights without causing distress to the child.
