The observational case describes bilateral recurrent keratoconus in corneal transplants performed in a patient with self-induced keratoconus secondary to compulsive eye rubbing. Slitlamp findings demonstrated corneal stromal thinning and scarring in the patient's right eye and temporal corneal hydrops in his left eye. Videokeratography of the right eye confirmed the presence of corneal steepening and irregular astigmatism, consistent with the diagnosis of keratoconus involving each transplant. Together with the history of ongoing compulsive eye rubbing, these findings support the concept that chronic mechanical trauma to the cornea may contribute to the development of keratoconus.
该观察病例描述了一名因强迫性揉眼继发圆锥角膜而接受角膜移植的患者出现双侧复发性圆锥角膜。裂隙灯检查发现，患者右眼有角膜基质变薄和瘢痕形成，左眼有颞侧角膜水肿。右眼的角膜地形图检查证实存在角膜陡峭和不规则散光，这与累及每只移植眼的圆锥角膜诊断相符。结合持续强迫性揉眼的病史，这些发现支持了角膜慢性机械性创伤可能促成圆锥角膜发展的观点。
