Regenerative Capacity of Anterior Chamber Injection of Eye Platelet-Rich Plasma for Pseudophakic Bullous Keratopathy

Purpose: To present successful management of moderate corneal edema following cataract surgery by using the application of eye platelet-rich plasma (E-PRP) in the anterior chamber in a case of pseudophakic bullous keratopathy.Methods and Results: A 44-year-old male presented to our clinic with a year of diminution of vision in the right eye, associated with intermittent photophobia and colored halos around lights, primarily upon waking in the morning.The patient had cataract surgery ten years ago.We use AS-OCT, slit lamp, and corneal pachymetry, which reveal multiple small subepithelial micro-and macrobullae involving the entire cornea, diffuse stromal edema, and mild thickening of Descemet's membrane with folds.We administer 0.3 mL of E-PRP into the anterior chamber under sterile conditions.Various medical treatments involving numerous drops have been unsuccessful.A sterile 0.3 mL of E-PRP was injected into the anterior chamber every 2 weeks for 1 month.Clinical and anatomical improvement began from the first week, and corneal edema resolved at 2 months.Postoperatively, no significant side effect was noted.We followed up with Slit lamp, anterior segment OCT, and corneal pachymetry, which showed improvement in corneal transparency and total disappearance of fluid in the cystic superficial epithelium.The patient is in a follow-up procedure. Conclusion:This study suggests that the therapeutic response to intracameral injection of E-PRP was satisfactory in moderate pseudophakic bullous keratopathy.In this case, intraocular E-PRP was a promising, safe, and effective treatment option for managing bullous keratopathy, for which conventional approaches had failed.
