Front Med (Lausanne). 2022 Aug 24;9:946828. Keratoneuralgia, a clinical diagnosis of sensitized corneal pain without visible ocular surface damage, generally has minimal response to conventional therapies. Causes include refractive surgery and chronic dry eye. We evaluated the efficacy of Plasma Rich in Growth Factors (PRGF), a novel treatment prepared using a commercially available kit, in patients with keratoneuralgia. A retrospective chart review identified patients who had the clinical diagnosis of keratoneuralgia and were treated with PRGF for at least 3 months from October 2015 to April 2020 at a single academic institution. Both objective eye exam findings and concurrent treatments were obtained at baseline, 3 months, and final visit (if available).

Cureus. 2022 Jul 6;14(7):e26623. Nowadays, infertility problems affect a high percentage of couples. This study aimed to evaluate the effect of plasma rich in growth factors (PRGF-Endoret, hereafter PRGF) as a promising coadjuvant therapy in assisted reproductive techniques and its possible role in implantation and pregnancy rates. This retrospective study included 36 PRGF cycles in 27 women with one of the following reproductive disorders: recurrent implantation failure (n = 16), repeated abortion (n = 8), and thin endometrium (n = 3).

Arch Soc Esp Oftalmol (Engl Ed). 2022 Apr;97(4):219-223. Full-thickness macular hole is a rare complication of macular telangiectasia type 2, and its treatment is still controversial. A patient with a full-thickness macular hole secondary to macular telangiectasia type 2 underwent vitreoretinal surgery with a plasma rich in growth factors membrane in the macular hole. At the sixth month of follow-up, anatomical and functional improvements were achieved, with no adverse effects.

Retin Cases Brief Rep. 2022 Mar 1;16(2):155-160. Persistent macular hole (PMH) is a challenge for retina surgeons. There are limited surgical techniques described achieving PMH closure. For more than a decade, techniques with blood derivatives have been described without optimal outcomes. The aim of this article is to report the usefulness of the plasma rich in growth factors (PRGF) as a new way to improve PMH closure.

Ann Anat. 2022 Feb:240:151853. doi: 10.1016/j.aanat.2021.151853. Scaffolds should have controllable degradation rate and allow cells to produce their own extracellular matrix. Platelet rich plasma (PRP) is a source of autologous growth factors and proteins embedded in a 3D fibrin scaffold. There is no consensus regarding the obtaining conditions and composition of PRPs.
