ABSTRACT
Macular translocation with 360 degree retinotomy (MT360) involves rotation of the retina with respect to the optic nerve, and so engenders misalignment between the visual axes of the two eyes. Macular translocation most often involves the superior movement of the macula and engenders intorsion. In the minority of cases of MT360, anatomic considerations require the vitreoretinal surgeon to translocate the macula downward, creating extorsion rather than intorsion in the operated eye. Extraocular muscle surgery carries with it the risk of inadvertent scleral perforation, especially near the equator of the globe in both superior temporal and inferotemporal quadrants, where exposure may be difficult and the scleral thickness highly variable. While MT360 can stabilize or reclaim vision lost from severe age-related macular degeneration, the surgery creates tilted vision and diplopia, which can be mitigated by extraocular muscle surgery.
