[Removal of congenital persistent pupilary membrane with sutureless clear corneal small incision]
1Zhongshan Ophthalmic Center, Sun Yat-sen University of Medical Sciences, Guangzhou 510060, China.
Purpose:
To investigate a new way in the treatment of serious congenital persistent pupilary membrane.
Methods:
In four cases of six eyes, after temporal clear corneal tunnel incision was made, viscoelastic material was injected into the anterior chamber, and the persistent pupilary membrane was cut down at the very point connected to the iris.
Results:
There is no ocular hypertention and hyphema after operation. After one year's follow-up, the lens remained transparent in 3 cases(4 eyes). There was corneal astigmatism of 0.12 to 0.25 D after operation. And only a few corneal endothelial cells were lost.
Conclusion:
There are few postoperative complications and corneal astigmatism to incise congenital persistent pupilary membrane by temporal clear corneal tunnel incision. It is an ideal way to treat serious persistent pupilary membrane.
