Diagnosis: corneal macular scar with neovascularization of the superior cornea

Image Comments:

The corneal scar is too visible to be called a nebula. Therefore, it is a macula. Bloodvessels are growing into the cornea superiorly. This qualifies as neovascularization since the bloodvessels go beyond the normal limbal arcade. The term pannus does not apply to pure neovasdcularization. Pannus must include a granulation tissue invasion of the cornea - not just new bloodvessels but also young vascularized connective tissue, i.e. granulation tissue. The absence of trichiasis involving the upper lid suggests that the corneal scarring is the residual of a previous keratitis and not the result of trachoma.
