Randomized Controlled Trial
The effect of hyaluronidase on ultrasound-measured dispersal of local anaesthetic following sub-Tenon injection.
To determine by B-scan ultrasonography if the addition of hyaluronidase affects the dispersal of anaesthetic fluid after sub-Tenon's injection. ⋯ The addition of hyaluronidase significantly augments the dispersal of local anaesthetic fluid, as measured by B-scan ultrasonography.
