1. An electrical stimulation apparatus for delivering therapeutic electrical stimulation to an eye of a patient, the apparatus comprising:
an implantable device comprising:
an elongate substrate having a distal end and a proximal end, wherein a length of the substrate in a longitudinal direction of the substrate extending between the distal and proximal ends of the substrate is between 5 mm and 15 mm; and
one or more electrodes located in or on the substrate, the electrodes configured for delivering therapeutic electrical stimulation to the eye, the implantable device being configured for implanting in a suprachoroidal space between the sclera and choroid layers of the eye;
wherein, when implanted, one or more distal-most electrodes of the one or more electrodes is located at a position beneath the retina of the eye, the substrate is not positioned beneath, and the one or more electrodes do not infringe on the central retina of the eye; and
a controller configured to control a delivery of therapeutic electrical stimulation to the eye using the one or more electrodes,
wherein the therapeutic electrical stimulation prevents or slows degradation of visual function of the eye.
