Keratoglobus

(ker-at-o-glo' -bus). Distention and protrusion of the cornea. The sclerotic may also, become distended in severe cases. When so extensive as to prevent closure of the lids, it has been called buphthalmos. When the distention is transparent, regular, and cone-shaped, the apex of the cone being the center of the cornea, it is called keratoconus, or conical cornea. When the protrusion is opaque, or connected with synechia of the iris, it is called staphyloma of the cornea, or anterior staphyloma. When due to increase in the fluids of the eye, with increased tension and uniform ectasia, it is called hydrophthalmos. Enlargement of the cornea is also called megalo-cornea.
