The study will provides the enrollment of patients with genetic retinal dystrophies with primary rod impairment.

A subretinal injection of umbilical cord blood platelet-rich plasma (CB-PRP) will be performed only in one eye, the other eye will be considered as a control group.

A complete morpho-functional ophthalmological evaluation will be performed in all patient at each control.


All patients underwent genetic evaluation and they reported different types of mutations that induce anatomic-functional impairment of the rods.

After selecting the patients to be enrolled, the study will proceed with the vitrectomy surgery and a subretinal injection of umbilical cord blood platelet-rich plasma (CB-PRP) provided by the Umbilical Cord Bank according to the procedures provided for by the current legislation on blood components for non-transfusion use.

A complete ophthalmological examination will be performed at 1, 3, 6 and 12 months. They will

  • Anterior segment biomicroscopy
  • direct and indirect ophthalmoscopy
  • ETDRS visual acuity assessment
  • intraocular pressure measurement
  • optical coherence tomography (OCT)
  • OCT Angiography (OCTA)

The following assessments will be performed at baseline and at 6 and 12 months.

  • Microperimetry
  • ERG (elettroretinogramma) -
  • PEV (potenziali evocati visivi)
  • contrast sensitivity (MARS tables)
  • Goldmann perimetry

The some morpho-functional data will also be collected in the contralateral eye and used as control group.

To ensure the best safety for the patient, the first 5 eyes will be separated by a minimum of 20 days in order to observe the post-surgical evolution.
