Zusammenfassung
Fragestellung
Die Trabekulektomie (TE) gilt als eine Operation der ersten Wahl in der Glaukomchirurgie. Der Einsatz von Antimetaboliten, insbesondere Mitomycin C, hat die Erfolgsrate gesteigert. Diese Studie soll die Ergebnisse nach TE mit 5-Fluorouracil (5-FU) vorstellen.
Methodik
Es wurden 71 konsekutive Trabekulektomien mit 5-FU bei dekompensiertem Glaukom und einer Nachbeobachtungszeit von 1 Jahr retrospektiv ausgewertet. Der absolute (ohne Therapie) und relative Erfolg (mit Therapie) wurde für die Druckniveaus ≤ 21 mmHg, ≤ 18 mmHg, ≤ 15 mmHg und ≤ 12 mmHg nach 6 und 12 Monaten berechnet. Daneben wurden postoperative 5-FU-Gaben, Needlingprozeduren und Komplikationen erfasst.
Ergebnisse
Bei der Auswertung wurden insgesamt n = 55 Patienten berücksichtigt. Der Augeninnendruck (IOD) war präoperativ 29,6 ± 7,3 mmHg (3 ± 1,4 Wirkstoffe, teils Diamox), nach 6 Monaten 13,2 ± 4,1 mmHg, nach 1 Jahr 13,7 ± 4,3 mmHg. Nach 6 Monaten zeigte sich ein absoluter Erfolg für die angegebenen Druckniveaus bei 92, 87, 79 bzw. 52 %. Ein relativer Erfolg zeigte sich bei 96, 90, 81 bzw. 54 %. Nach 12 Monaten zeigte sich ein absoluter Erfolg für die angegebenen Druckniveaus bei 87, 84, 51 bzw. 56 %. Ein relativer Erfolg zeigte sich bei 96, 93, 58 bzw. 58 %. Einsatz von 5-FU postoperativ: keine Intervention bei n = 30; subkonjunktivale 5-FU-Gaben bei n = 25; Needling mit 5-FU bei n = 6. Eine passagere Hypotonie mit flacher Vorderkammer zeigte sich bei 6 Patienten, Kataraktentwicklung bei 5 Patienten. Ein Patient erlitt eine Hornhautdekompensation bei Zustand nach multiplen Voroperationen.
Schlussfolgerung
Die TE mit intraoperativer 5-FU-Gabe zeigt sehr gute Erfolgsraten nach 1 Jahr. Schwerwiegende Komplikationen werden selten beobachtet. Die intraoperative 5-FU-Gabe stellt eine mögliche Alternative zur TE mit Mitomycin C dar.
Abstract
Purpose
Trabeculectomy is among the first choice surgical treatments for glaucoma. Antimetabolites, especially mitomycin C, have improved the success rate. The aim of this study is to present the results of trabeculectomy with 5-fluorouracil (5-FU).
Methods
A total of 71 consecutive trabeculectomies with 5-FU for decompensated glaucoma with at least 1 year follow-up data were retrospectively evaluated. The absolute (without therapy) and relative (with therapy) success rates for glaucoma medication were determined for intraocular pressure (IOP) levels of ≤ 21 mmHg, ≤ 18 mmHg, ≤ 15 mmHg and ≤ 12 mmHg respectively. Postoperative 5-FU administration rates, needling procedures and complications were recorded.
Results
Sufficient follow-up data were available for a total of 55 patients. The average IOP was preoperatively 29.6 ± 7.3 mmHg (3 ± 1.4 active ingredients, partly acetazolamide), after 6 months 13.2 ± 4.1 mmHg and after 1 year 13.7 ± 4.3 mmHg. Complete success at 6 months postoperatively for the given pressure levels: were 92 %, 87 %, 79 % and 52 % and at 1 year 87 %, 84 %, 51 % and 56 %, respectively. Postoperative relative success for these pressure levels at 6 months were 96 %, 90 %, 81 % and 54 % and at 1 year 96 %, 93 %, 58 % and 58 %, respectively. Administrations of 5-FU postoperatively were no intervention (n = 30 patients), subconjunctival 5-FU administration (n = 25) and needling procedures (n = 6). A temporary hypotension with a shallow anterior chamber was seen in 6 patients, cataract development in 5 patients and 1 patient developed corneal decompensation (multiple previous operations before trabeculectomy).
Conclusion
Trabeculectomy with intraoperative 5-FU administration showed very high success rates after 1 year. Serious complications were rarely seen. Intraoperative 5-FU administration can be considered as an alternative treatment to trabeculectomy with intraoperative use of mitomycin C.
