Successful Repair of Recurrent Optic Disk Pit Maculopathy with Autologous Platelet Rich Plasma: Report of a Surgical Technique.

PURPOSE To describe vitreoretinal surgical technique of using autologous platelet-rich plasma to aid in surgical repair of optic pit maculopathy refractive to previous vitrectomy. METHODS A case of an 18-year-old woman presenting with serous macular detachment secondary to optic pit is reported. Patient had previously undergone vitrectomy and peripapillary laser, but had recurrence of subretinal fluid and worsening visual acuity. Autologous platelet-rich plasma was harvested from the patient's blood and purified using Arthrex ACP kit (Arthrex, Inc, Naples, FL). Repeat pars plana vitrectomy was performed with internal limiting membrane peeling extending to the optic nerve. Platelet-rich plasma was layered over the pit and long-acting gas tamponade performed with face-down positioning. RESULTS At 8 months of follow-up, subretinal fluid was resolved, the connection between optic pit and subretinal space collapsed and the ellipsoid zone near completely reconstituted on optical coherence tomography. The patient's vision improved significantly from 20/100 to 20/50, which is largely limited by posterior subcapsular cataract. CONCLUSION Platelet-rich plasma can augment anatomical and visual outcomes in surgical repair of optic pit maculopathy.
