A new technique for removing the inner wall of Schlemm's canal using cyanoacrylate.
OBJECTIVE
To introduce a new technique for removing the inner wall of Schlemm's canal using cyanoacrylate.


METHODS
Two donor eyes were used in this study. A limbal-based scleral flap was dissected. The external wall of Schlemm's canal was opened and the inner wall of Schlemm's canal was exposed. Ethyl-2-cyanoacrylate was applied uniformly to the inner wall. After it had solidified, it was removed with fine forceps. The operated sites were then studied by light microscopy.


RESULTS
After cyanoacrylate removal, the aqueous humour was seen percolating through the thin remaining trabecular meshwork. Histopathological findings at the operated sites revealed that the lining of the Schlemm's endothelial cells was irregular. Endothelial cell nuclei were rarely seen along the canal wall. Microperforation to the anterior chamber was not seen.


CONCLUSIONS
This new technique is potentially a safer method for removing the inner wall of Schlemm's canal than the conventional method.
