Abstract
Aim To evaluate the long-term outcomes of intravitreal triamcinolone acetonide (TA) administration after posterior vitreous detachment (PVD) during pars plana vitrectomy (PPV) for patients with proliferative diabetic retinopathy (PDR).
Methods A total of 189 eyes (152 patients) who underwent PPV for severe PDR were reviewed. Intravitreal injection of TA (IVTA) was administered during PPV in 118 eyes (PPV+IVTA group), and 71 eyes did not receive IVTA (PPV group). Immediately after PVD, when most of the vitreous and proliferative membranes were removed, 0.1 mL TA (40 mg/mL) was injected into the vitreous cavity in the PPV+IVTA group. All patients were followed-up for least 12 months. Visual outcomes and postoperative complications were recorded and compared between the two groups.
Results IVTA was helpful for proliferative membrane peeling and haemostasis during PPV. In the PPV+IVTA group, best-corrected visual acuity had significantly improved and the intraocular pressure was controlled well during the follow-up. The incidence of early recurrent vitreous haemorrhage after PPV was significantly lower in the PPV+IVTA group (1.7%) than in the PPV group (9.9%) (p=0.028).
Conclusion The administration of IVTA after PVD during PPV can effectively improve the final visual outcomes and prevent postoperative complications in patients with severe PDR.
