I would say in general terms that loss of peripheral vision be it from glaucoma, stroke, retinal disease like retinitis pigmentosa or other causes is usually not something that can be rehabilitated. There are some new computer programs with vision simulators that try to help patients try to rehabilitate the use of lost peripheral vision mainly from stroke and there has be at least some encouraging, though limited, results with that.
I would recommend that you seek the care of your eyeMD to determine the cause of your peripheral field loss. Sometimes, prevention of further loss can occur.
