Reconstruction of the lower lid in congenital microphthalmos and anophthalmos.

In congenital microphthalmos and anophthalmos, the socket and lids are often underdeveloped. Progressive dilation of the socket often does not increase the horizontal lid aperture or permit the use of a larger prosthesis. The authors present two cases in which a modified Mustarde cheek flap, lined with a tarsal-conjunctival graft, was used to reconstruct and lengthen the lower lid. This procedure results in a larger horizontal lid aperture and permits a larger prosthesis to be contained in the socket.
