Sustained-release subconjunctival 5-fluorouracil.

BACKGROUND AND

OBJECTIVES

The purpose of this research was to obtain preliminary safety and efficacy data on a novel sustained-release 5-fluorouracil (5-FU) implant in high-risk glaucoma surgical patients.

PATIENTS AND

METHODS

The implants were placed subconjunctivally in four patients undergoing high-risk trabeculectomy. The patients have been observed for approximately 2.5 years.

RESULTS

In three of the four patients intraocular pressure was controlled at less than 21 mm Hg, with stabilization of the visual field. One patient had early failure. No untoward events were linked to the placement of the implant.

CONCLUSION

Sustained-release systems for subconjunctival 5-FU may be useful in filter maintenance.
