A total of 16, every other day sessions of rTMS at 10 Hz frequency will be applied to 4 locations along the perilesional area (see target selection). Intensity will be 100% of motor threshold, 25 trains - 40 pulses per train with 20 seconds intertrain interval and a total of 1000 pulses per session. The coil handle will be directed downwards at 45º of the sagittal plain to ensure that the induced electric field be perpendicular to the underlying gyrus.

Sham group will receive the same sessions as above with the exact same parameters yet a sham coil identical in shape and size to the active coil will be used instead. The sham coil produces sounds and sensations very similar to the active one.

10hz, 20 seconds intertrain interval, 40 pulses per train with a total of 1000 pulse per session given at 100% of motor threshold. A total of 16 sessions will be given to each patient.

High frequency repetitive transcranial magnetic stimulation (rTMS)

A sham coil will be used that is shielded so that it produces sounds and sensations similar to the active coil but does not produce therapeutic effects. 10hz, 20 seconds intertrain interval, 40 pulses per train with a total of 1000 pulse per session given at 100% of motor threshold. A total of 16 sessions will be given to each patient.

Repetitive Transcranial Magnetic Stimulation for Post-Stroke Visual Field Defects

The Efficacy of Navigated Perilesional Repetitive Transcranial Magnetic Stimulation on Post-Stroke Visual Field Defects

Change in mean deviation (MD) from baseline will be assessed using automated perimetry's full threshold 30-2 visual field test.

Change in visual field index (VFI) from baseline will be assessed using automated perimetry's full threshold 30-2 visual field test.

This questionnaire measures the dimensions of self-reported vision-targeted health status that are most important for the daily functioning of patients with visual field defects. It has 12 sub-scale scores each with a 0 to 100 scale. These sub-scale scores are then averaged to produce a 0 to 100 overall score where higher score represents better outcome.
