Current retinal procedures to repair detachments or RIPS, for example, may involve several incisions in the eye and stitches to tie off the perforated areas.

The team took electrical readings from single isolated retinal horizontal cells. They found that light caused a change in electrical current in cone horizontal cells but not in rod horizontal cells.

Transplantation of normal healthy RPE cells with an attempt to treat the retinal diseases is one of the current interests in ophthalmic research.
