    Abstract:
    BACKGROUND: To describe our experience of combined trabeculotomy-trabeculectomy in paediatric glaucomas with a special emphasis on the use of 5-fluorouracil and releasable sutures. DESIGN: Retrospective review carried out at Manchester Royal Eye Hospital, UK, a tertiary referral centre. PARTICIPANTS: Twenty-nine eyes of 21 consecutive patients with congenital glaucoma undergoing combined trabeculotomy-trabeculectomy augmented with 5-fluorouracil. METHODS:   5-Fluorouracil augmented combined trabeculotomy-trabeculectomy was carried out with intense postoperative management and suture adjustment of releasable sutures within the first 3 weeks after surgery. Peribleb 5-fluorouracil injections were given repeatedly if there were signs of aggressive bleb scarring. MAIN OUTCOME MEASURES: Absolute success was defined as intraocular pressure of 21 mmHg or less, clear cornea and absence of progressive glaucomatous optic disc changes at last follow up, whereas qualified success was defined as these endpoints with anti-glaucoma medication. RESULTS: Absolute success was achieved in 19 out of 29 eyes (65.5%), and a further 4 (13.8%) had qualified success. There was no difference in the surgical outcomes of primary infantile glaucoma and secondary causes of paediatric glaucoma such as anterior segment dysgenesis. Combined trabeculotomy-trabeculectomy had a significantly greater success rate as a secondary procedure rather than as a primary procedure. CONCLUSION: 5-Fluorouracil-enhanced combined trabeculotomy-trabeculectomy with releasable sutures appears to be an effective procedure for congenital glaucoma refractory to goniotomy. It is less effective as a primary procedure when severe corneal haze prevents goniotomy in newborn congenital glaucoma. Intense postoperative monitoring including active bleb manipulation with needling and 5-fluorouracil injections may increase the success of the procedure.
