A graft-free scleral sleeve technique of Ahmed Glaucoma Valve implantation in refractory glaucoma- Rising to the challenge of COVID-19 pandemic

We describe a case of 63-year-old woman, with primary open-angle glaucoma (POAG) who presented to us in the COVID era with uncontrolled intraocular pressure (IOP) on maximum medical therapy (MMT) in the right eye (OD), previously operated twice for trabeculectomy in (OD), and once in left eye (OS). A modified graft-free surgical technique of inserting the Ahmed Glaucoma valve (AGV) tube through a scleral sleeve was employed. Visual acuity and IOP remained stable during 6-month follow-up period.
