NCT06323902

Brief Summary

For a series of patients with full-thickness macular hole, an autologous plasma rich in growth factors was developed in the form of a clot and applied to the retinal defect. These patients were followed up for a period of one year, obtaining substantial improvement both anatomically and functionally.

Outcome Measures

Primary Outcomes (1)

  • Macular hole closure

    The closure of the macular hole after PRGF membrane implantation was evaluated.

    Follow-up was carried out for 1 year

Study Arms (1)

Patients with giant full thickness macular hole

13 patients with a diagnosis of macular hole with a total thickness greater than 400 microns were chosen. Without prior vitreoretinal surgery

Procedure: Pars plana vitrectomy, with or without epiretinal membrane peeling, plus PRGF membrane implantation

Interventions

In the operating room through pars plana vitrectomy after having completed the complete air exchange, with the help of a Backwash Charles cannula, the PRGF membrane is placed in the macular hole and C3F8 gas is left in the posterior chamber, the first hour in the recumbent position. supine and subsequently face down during the first postoperative week.

Also known as: PRGF membrane implantation

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersYes
Age GroupsAdult (18-64), Older Adult (65+)
Sampling MethodNon-Probability Sample
Study Population

13 patients were chosen with a diagnosis of macular hole with a total thickness greater than 400 microns, over 18 years of age, with no history of previous vitreretinal surgery or with other retinal pathologies. The triggering factors in 46% were due to the presence of an Epiretinal Membrane (6 cases) and 54% were due to vitreomacular traction (7 cases).

You may qualify if:

  • Patients with a diagnosis of macular hole with a total thickness greater than 400 microns
  • Patients without prior vitreoretinal surgery
  • Patients over 18 years of age

You may not qualify if:

  • Patients under 18 years of age
  • Patients with previous vitreoretinal surgery
  • Patients who had other additional retinal pathologies (diabetic retinopathy, hypertensive retinopathy, vascular retinal occlusions, retinal detachment, etc.)
