To report the results of vitrectomy with platelet-rich plasma (PRP) application and gas tamponade as a rescue therapy in previously vitrectomized eyes with optic disk pit (ODP) maculopathy.
Three patients with visual loss due to persistent or recurrent ODP maculopathy who had undergone previous vitrectomy were offered application of PRP. Platelet-rich plasma was obtained by centrifugation of a blood sample from each patient. Surgery consisted of vitrectomy and internal limiting membrane peeling if the membrane had not been already removed (in two eyes). After fluid/air exchange, three drops of PRP were applied on the ODP followed by 8% C3F8 tamponade. Immediately after surgery, the patient remained supine for 30 minutes and then kept a face-down position for 2 weeks.
Optic disk pit maculopathy improved as soon as two weeks after surgery and resolved in all eyes between six and eight months after PRP application. Patients were followed up for three years, with no recurrences. Visual acuity remained stable in one eye and improved in two eyes.
Vitrectomy with PRP application may be useful as a rescue therapy in patients with refractory ODP maculopathy. Platelet-rich plasma may act by promoting the closure of the communication between the vitreous and the intraretinal/subretinal space at the pit. This treatment may avoid potentially harmful maneuvers that have been used to treat ODP maculopathy.
报告在既往已行玻璃体切除术的视盘小凹(ODP)黄斑病变眼中,应用富含血小板血浆(PRP)及气体填塞进行玻璃体切除术作为挽救治疗的结果。
为3例因持续性或复发性ODP黄斑病变导致视力丧失且既往已行玻璃体切除术的患者应用PRP。通过离心每位患者的血样获得富含血小板血浆。手术包括玻璃体切除术以及如果尚未切除内界膜则进行内界膜剥除(2只眼)。在液体/空气交换后,在视盘小凹处滴入3滴PRP,随后用8%的C3F8进行填塞。术后患者立即仰卧30分钟,然后保持面朝下体位2周。
术后2周视盘小凹黄斑病变即有改善,在应用PRP后6至8个月所有眼的病变均消退。患者随访3年,无复发。1只眼视力保持稳定,2只眼视力提高。
应用PRP的玻璃体切除术可能作为难治性ODP黄斑病变患者的挽救治疗方法有效。富含血小板血浆可能通过促进视盘小凹处玻璃体与视网膜内/视网膜下间隙之间的连通闭合而发挥作用。这种治疗可能避免用于治疗ODP黄斑病变的潜在有害操作。
