Treatment outcomes of paul versus ahmed glaucoma implants
Fig 1
The base plate of a Paul® glaucoma implant is placed in the supero-temporal quadrant beneath the recti muscles.
A 6−0 non-absorbable monofilament polypropylene suture (Prolene, Ethicon, Johnson & Johnson Medical GmbH, Norderstedt, Germany) is partly inserted into the tube to reduce immediate aqueous humour flow and to prevent early postoperative hypotony (a). The tip of the tube is guided through a deep scleral tunnel into the anterior chamber (b). The part of the tube that lies on the sclera is covered with a corneal donor patch (c). The conjunctiva is closed using Vicryl 8−0 (Ethicon) (d).
