Abstract Details



Purpose:

A surgical technique is described to facilitate membrane peeling in patients with macular diseases by using small amount of perfluorocarbon (PFC) liquid and brilliant blue G (BBG) dye.

Setting:

Department of Ophthalmology, Faculty of Medicine, University of Tsukuba, Ibaraki, Japan

Methods:

After placing PFC liquid of about 1.0-1.5 cc on the macular area, BBG was applied with a 27-gauge blunt needle at the interface of PFC liquid and retina. The membrane peeling was performed under PFC liquid.

Results:

The PFC liquid-assisted staining technique required significantly less amount of BBG dye than the conventional staining method (P<0.001). Since the displacement angle of the membrane during peeling procedures is considerably increased by PFC liquid, combined with its high specific gravity and interfacial tension, the risk of tearing the membrane is reduced a great extent during manipulation.

Conclusions:

The PFC liquid-assisted technique enables sufficient membrane staining with minimal amount of BBG dye, and tearing of the epiretinal membrane or internal limiting membrane becomes less likely than the conventional method.
