Purpose:
To report a case of Descemet membrane detachment after sequential argon-neodymium (Nd):yttrium-aluminum-garnet (YAG) laser peripheral iridotomy.
Design:
Interventional case report.
Methods:
A 72-year-old Chinese man presented with acute primary angle-closure in the left eye. In the fellow right eye, a localized Descemet membrane detachment developed after prophylactic sequential argon-Nd:YAG laser peripheral iridotomy. Ultrasound biomicroscopy pictures were taken.
Results:
The Descemet membrane detachment reattached gradually without intervention. The cornea remained clear and the vision was unchanged.
Conclusion:
In sequential argon-Nd:YAG laser peripheral iridotomy, the shock wave formed during photodisruption may produce linear cracks at the level of Descemet membrane, resulting in detachment. This complication can occur irrespective of the color of the iris.
