Materials and Methods: Fifty-four eyes of 54 patients with the diagnosis of various retinal disease were included in this study. Retinal detachment (RD) in 40 eyes, lens luxation to vitreous in 3 eyes, epiretinal membran (ERM) in 3 eyes, intravitreal foreign body (IVFB) in 2 eyes, macular hole in 4 eyes and vitreous haemorrhage (VH) in 2 eyes were detected. After pars plana vitrectomy, the visualization of the vitreous and posterior hyaloid was facilitated by using triamcinolone suspension injected into mid vitreous cavity. Thus, after complete removal of the vitreous and posterior hyaloid, ERM and internal limiting membrane (ILM) peeling was performed more easily. The anatomical succes rate, final visual acuity and postoperative complications were prospectively evaluated. The mean follow-up time was 5.3 months (range, 2-9 months).

Results: In 30 eyes (%55.5), the visual acuity was increased, in 15 eyes (%27.8) remained unchanged and in 9 eyes (%16.7) was worsened. Intraoperative reattchment was achieved in all patients with retinal detachment. Recurrent retinal detachment occured in 7 patients (%12.9). Increased intraocular pressure (higher than 21 mmHg) was detected in 10 eyes (%18.5) after the operation. Epiretinal membrane formation was observed in 3 eyes postoperatively. No other significant postoperative complications were detected in any patient.

Conclusion: Triamcinolone assisted pars plana vitrectomy allows the complete removal of vitreous and the delineation of the posterior hyaloid, increases the safety and rapidity of the surgical procedure. Keywords : Triamcinolone, pars plana vitrectomy
