Viscoelastic agent retention and failed macular hole surgery.
OBJECTIVE
To describe the retention of a viscoelastic agent as a possible cause of failed macular hole surgery.


METHODS
Three consecutive patients underwent macular hole surgery. A bubble of viscoelastic agent was used to prevent contact between indocyanine green dye and retinal pigment epithelium cells.


RESULTS
Macular hole repair failed in all three cases. After a second surgery the holes closed successfully.


CONCLUSIONS
The use of a dispersive viscoelastic agent to avoid indocyanine green toxicity in macular hole surgery may prevent the closure of the hole.
