Transconjunctival 25-gauge sutureless vitrectomy and silicone oil injection in diabetic tractional retinal detachment.

PURPOSE: The purpose of this article was to evaluate the outcomes and complications of transconjunctival sutureless 25-gauge vitrectomy using silicone oil tamponade in diabetic tractional retinal detachment.

MATERIALS AND

METHODS

Patients were retrospectively evaluated. Main outcome measure was the feasibility of pars plana vitrectomy and silicone oil injection with 25-gauge system in eyes with diabetic tractional retinal detachment.

RESULTS

Fourteen eyes of 14 patients were included in the study. Tractional retinal detachment was accompanied by vitreous hemorrhage in 9 eyes and combined traction/rhegmatogenous retinal detachment was present in 1 eye. All patients underwent transconjunctival sutureless 25-gauge vitrectomy and 1,000 centistokes silicone oil injection. Angled insertion of the trocars was made in all eyes. Bimanual surgery was performed in 6 (42.8%) eyes. The median preoperative best-corrected visual acuities were 3.00 logarithm of the minimum angle of resolution; it increased to 1.60 logarithm of the minimum angle of resolution at last visit. Retinal tear formation occurred in 4 (28.5%) eyes. Retinal detachment developed in 2 (14.2%) eyes. Intraocular pressure of 5 mmHg or less was detected in 3 (21.4%) eyes. One patient lost light perception due to anterior hyaloidal fibrovascular proliferation.

CONCLUSION

Pars plana vitrectomy and 1,000 centistokes silicone oil injection with 25-gauge system is feasible in diabetic tractional retinal detachment even in complex cases. Indications of 25-gauge surgery may be expanded toward this area.
