title: Right half-field eye patching may not be an effective approach for chronic hemispatial neglect--a two-case investigation.
abstract: Right half-field eye-patched glasses intervention was performed in two chronic stroke patients with unilateral spatial neglect. Eye movement on the neglect side, the center of gravity as an index of the internal midline bias, neglect sign tests, and the regional cerebral blood flow (rCBF) were measured before and after intervention. The improvement of eye movement was not shown clearly after intervention. The center of gravity shifted significantly to the right and backward. Letter and star cancellation tests were improved in both the cases. Line bisection test showed improvement in one patient. However, line cancellation and line bisection tests were worsened in the other. The rCBF was not changed after intervention. This case study suggests that right half-field eye patching might not be an effective intervention.
