Abstract: An elongate elastomeric band having unitary construction which construction includes a silicone sponge differentially compressive portion disposed along the length thereof. The band is dimensioned to encircle the eye of a patient having a detached retina. In use, the band is placed around the eye and surgically attached thereto in an encircling position. The band circumferentially deforms the sclera, particularly the portion of the sclera overlying the area of retinal detachment, the differentially compressive portion forcing the choroid and detached portion of the retina into juxtaposition for reattachment. The band, which includes a closed-cell silicone foam differentially compressive portion along a section of its length, is manufactured by means of extrusion providing an elastomeric, preferably silicone, band having unitary construction and varying in both its outer dimension and its compressibility along the length thereof.
