Retinal relieving incisions.

Retinal relieving incisions were undertaken during closed microsurgery for the treatment of retinal detachment complicated by retinal shortening as a result of incarceration or irresectable epiretinal membranes. In 16 of 20 eyes the retina remained attached after a minimum follow up of six months. Visual acuity of 2/60 or better was achieved in eleven of the 20 eyes and seven eyes had an acuity of 6/60 or better. Retinal relieving incisions are required in a minority of retinal re-attachment procedures and are compatible with useful visual function.
