PURPOSE
To describe a case with clinicopathologic findings of spheroidal degeneration of the cornea in a 78-year-old man.
METHODS
Description of the clinical features of 1 bilateral case with histopathologic findings from the penetrating keratoplasty specimen.
RESULTS
Spheroidal degeneration of the cornea with histopathologic confirmation of extensive elastotic degeneration in anterior corneal stroma.
CONCLUSIONS
The spheroidal degeneration in this patient was of visual significance. The history of repeated, extreme ultraviolet exposure during arc welding is believed to be the proximal cause of these corneal changes.
目的
描述一名78岁男性角膜球状变性的临床病理表现。
方法
描述1例双侧病例的临床特征，并给出穿透性角膜移植术标本的组织病理学结果。
结果
角膜球状变性，组织病理学证实角膜前基质有广泛的弹性变性。
结论
该患者的角膜球状变性具有视觉意义。据信，电弧焊期间反复暴露于极强紫外线的病史是这些角膜变化的直接原因。
