Histology of microcornea complicated by bullous keratopathy

Abstract

ABSTRACT.Purpose: To report a child with a microcornea complicated by bullous keratopathy and to present the results of a developmental and histological investigation of a microcornea. Methods: Clinical and histopathological examination. Results: Histopathological examination of the microcornea showed that the microcornea of our case lacked the non-banded zone of Descemet's layer and formed collagenous layer and secondary Descemet's membrane. Conclusion: This case demonstrates that histological finding of microcornea is not necessarily normal.

Microcornea associated with myopia

“…It was found that the corneal surface was flat and the thickness of the cornea was normal. However, the endothelial layer disclosed serious degeneration, similar to bullous keratopathy, as reported previously [4]. Shallower anterior chamber and myopic refraction with myopic retinal degeneration were also present in this case.…”

“…According to the latest study dealing with the determination of the diameters of the cornea, the lower limit is 11.0 mm in the case of men and 10.7 mm in the case of women [7]. Inoue in his study makes an account of the presence of secondary Descemet's membrane in the case of microcornea [4].…”
