³Beyoğlu Göz Eğitim ve Araştırma Hastanesi, II. Göz Kliniği, İstanbul, Asist. Dr. Purpose: To compare anatomical and functional outcomes of 25 gauge sutureless pars plana vitrectomy (PPV) and 20 gauge PPV in eyes with diabetic vitreous hemorrhage (VH).
Materials and Methods: IIn this interventional case series 15 eyes (Group 1) underwent 20-gauge PPV, and 29 eyes (Group 2) underwent 25 gauge sutureless PPV with oblique sclerotomies due to diabetic VH. Eyes with a minimum follow-up of 6 months were evaluated. The main outcome measures were changes in visual acuity (VA), intraocular pressure (IOP), and rates of complications.
Results: In all eyes PPV was performed without complication. The mean follow-up period was 14±9.14 months. Mean VA in Group 1 increased significantly at postoperative week 1 and thereafter, whereas it increased in Group 2 at postoperative month 1 and thereafter (p<0.05). Mean log- MAR change, mean IOP levels, and rates of complications did not differ significantly between the two groups during follow-up (p>0.05). Transient hypotony was detected in 3 eyes in Group 2 only (p>0.05). Revitrectomy was performed in 1 (6.66%) and 3 (10.34%) eyes due to postoperative rehemorrhage in the two groups, respectively (p>0.05).
Conclusions: In this study 25 gauge sutureless pars plana vitrectomy with oblique sclerotomies and 20 gauge vitrectomy were similarly effective and safe in the treatment of diabetic VH. Further prospective randomized and controlled studies with larger series and with longer follow-up are warranted.
