INTRODUCTION: This article compares and evaluates the safety and clinical results of 3techniques for the management of hyper-filtrating ischaemic bleb in glaucoma, such as collagen crosslinking (CXL) with riboflavin versus conjunctival sliding and conjunctival autologous graft. METHODS: A total of 24 eyes were selected from 18 patients with ischemic blebs that underwent filtering glaucoma surgery between 2012 and 2017 and subjected them to crosslinking using riboflavin (n=4), conjunctival autologous graft (n=5), and conjunctival sliding (n=15). The results of the intraocular pressure (IOP) prior to the procedure and at 12 months were compared, as well as visual acuity and previous anti-glaucoma medication at 12 months. RESULTS: The 4eyes that underwent CXL, went from a previous mean IOP of 12.11 ± 3.14 to an IOP of 12.32 ±5.29 at one year (P=.655). Five eyes were treated by conjunctival autologous graft, had a previous mean IOP of 11.65 ± 5.76 and an IOP at one year of 14.68 ± 7.21 (P=.273). Fifteen eyes subjected to conjunctival sliding had a previous IOP of 9.32 ±5.34 and at one year it was 15.16 ± 9.24 (P=.021). There were no adverse effects or complications associated with any of the 3techniques. CONCLUSIONS: The management of the hyper-filtrating ischaemic bleb is difficult. Surgical procedures are associated with increased IOP and need for medication, while CXL using riboflavin and UV radiation does not seem to have an effect on the revitalisation of the bleb.
