Phacoemulsification in patients with previous trabeculectomy: Role of 5-fluorouracil
Sharma TK; Arora S; Corridan PGEye 2007; 21: 780-783
PURPOSE: Cataract surgery in a patient with previous trabeculectomy is considered to have an adverse effect on the long-term survival of the filtering bleb. 5-Fluorouracil (5-FU) has been used in patients with a pre-existing bleb, undergoing cataract surgery, but there are no published reports for or against its use in such cases. This study was carried out to evaluate the protective role of subconjunctival 5-FU on the pre-existing bleb from trabeculectomy in patients undergoing phacocoemulsification. METHODS: This retrospective study was carried out on patients with pre-existing filtering bleb from trabeculectomy for primary open-angle glaucoma who then underwent phacoemulsification at least 12 months after trabeculectomy. Data were collected for two groups of patients. Group 1 (22 patients) received 5-FU at the end of successful phacoemulsification, whereas group 2 (25 patients) did not receive it. The two groups were comparable with respect to age, gender, intraocular pressure (IOP), type of glaucoma, number of adverse risk factors present, and duration of follow-up. Any worsening of IOP control was analysed using mean IOP and mean change in the treatment for glaucoma.ResultsMean IOP was comparable in the two groups, but there was a significant difference in mean change in glaucoma treatment between the two groups at 12 months postoperatively. Worsening of IOP control was seen in 13.6% of the patients in group 1 and in 36.4% in group 2 (P-value = 0.03). CONCLUSION: Our study suggests that 5-FU has a protective effect on the functioning bleb and may be used routinely at the end of phacoemulsification in such cases.
