Abstract

Wir stellen eine neue Hybridmethode einer kombinierten 23/25 G-Pars-plana-Vitrektomie (PPV) zur Ölentfernung (5700 Centistokes) vor und vergleichen sie mit einer 25 G PPV. Bei der Hybridmethode erfolgt die Infusion über einen 25-G-Zugang und die Absaugung des Öls über einen 23-G-Zugang. Es wurden die Operationszeit und der postoperative intraokuläre Druck (IOD) ausgewertet. Die Operationszeit konnte mit der Hybrid-Methode signifikant um 32,2 % reduziert werden. Postoperativ bestand kein IOD-Unterschied. Schlussfolgerung: Die Entfernung von Silikonöl durch einen 25-G-Zugang ist generell möglich, wobei die neue Hybridmethode die Operationszeit deutlich reduziert.

Translated abstract

This article presents a new hybrid method of a combined 2‑port 23/25G pars plana vitrectomy for removal of silicone oil (5700 centistokes) compared to a 25G vitrectomy. In this hybrid technique the infusion is performed through a 25G cannula and the oil removal through a 23G cannula. The duration of the surgery and the intraocular pressure (IOP) in both groups were compared. The oil removal using the hybrid technique was performed significantly faster with a reduction of the time by 32.2% but there was no difference in the IOP. In conclusion, silicone oil removal through a 25G cannula is generally possible but oil removal with the new hybrid technique is much faster.

Initial experience using the transconjunctival sutureless vitrectomy system for vitreoretinal surgery.

Yoko Fujii-Nishimura, Eugene de Juan, S. Humayun … (2002)

To describe the initial experience and to evaluate the safety and feasibility of using the 25-gauge Transconjunctival Sutureless Vitrectomy System (TSV) for a variety of vitreoretinal procedures. Retrospective review of a consecutive interventional case series. Thirty-five eyes of 33 patients, including cases of idiopathic epiretinal membrane (12 cases), retinal detachment (6 cases), macular hole (5 cases), branch retinal vein occlusion (4 cases), retinopathy of prematurity (4 cases), persistent diabetic macular edema (1 case), diabetic vitreous hemorrhage (1 case), retained lens material after cataract extraction (1 case), and Norrie disease (1 case). All patients underwent surgery using the 25-gauge TSV. Intraocular pressure, visual acuity, and postoperative complications. The median preoperative intraocular pressure was 16 mmHg (range, 10-21 mmHg), whereas the median intraocular pressure on the first postoperative day was 12 mmHg (range, 6-28 mmHg). The median intraocular pressure at 1 week and 1 month were both 16 mmHg (range, 10-30 mmHg). Overall, the median preoperative visual acuity was 20/100 (range, 20/30 to hand motions), and the median postoperative visual acuity after a mean follow-up of 14 weeks (range, 1-60 weeks) was 20/60 (range, 20/20-20/150). One eye developed a postoperative retinal detachment. The 25-gauge TSV seems to be practical and safe for a variety of vitreoretinal procedures. The concept of transconjunctival surgery has the potential to increase the efficiency of a variety of vitreoretinal surgeries and possibly hasten the postoperative recovery and outcomes in several conditions by simplifying the surgical procedure; minimizing surgically induced trauma; and decreasing the convalescence period, the operating time, and the postoperative inflammatory response.
