BACKGROUND
Corneal endothelial damage is a known complication of aqueous shunt surgery.
OBJECTIVE
To describe a new technique for repositioning the Ahmed glaucoma valve tube in a case of tube-endothelial touch.
CASE
A patient with advanced glaucoma, having undergone Ahmed glaucoma valve (AVG) implantation, developed localized corneal endothelial damage due to contact between the tube and superior corneal endothelium. Two 10-0 prolene anchor sutures were passed over the tube in the anterior chamber, repositioning it away from the endothelium, thus preventing further damage to the corneal endothelium. Resolution of corneal oedema was noted without affecting the tube drainage and intraocular pressure.
CONCLUSION
Intracameral repositioning of the shunt tube using prolene sutures is a useful technique for correcting the tube malposition.
背景
角膜内皮损伤是房水引流手术已知的并发症。
目的
描述一种在引流管与角膜内皮接触的病例中重新定位艾哈迈德青光眼引流阀引流管的新技术。
病例
一名晚期青光眼患者，在植入艾哈迈德青光眼引流阀（AVG）后，因引流管与角膜上方内皮接触而出现局限性角膜内皮损伤。在前房内，两根10-0聚丙烯固定缝线穿过引流管，将其重新定位使其远离内皮，从而防止对角膜内皮造成进一步损伤。观察到角膜水肿消退，且未影响引流管引流及眼压。
结论
使用聚丙烯缝线在前房内重新定位引流管是纠正引流管位置不当的一种有用技术。
