Megalocornea (MGCN, MGCN1) is an extremely rare nonprogressive condition in which the cornea has an enlarged diameter, reaching or exceeding 13 mm.
It is thought to have two subforms, one with autosomal inheritance and the other X-linked (Xq21.3-q22).
[1] The X-linked form is more common and males generally constitute 90% of cases.

[3]In rare cases, it might be associated with intellectual disabilities.
