We report and compare 2 cases of open globe injury with foveal damage incurred while mowing. Case 1 is a healthy 67-year-old man presenting with an intraocular metallic foreign body and eye pain in his right eye after using a mower. The foreign body perforated the cornea’s inferior area and damaged the foveal centralis, leading to central scotoma and decreased visual acuity. 27G pars plana vitrectomy was performed, and the final corrected decimal visual acuity was 0.1, but the visual field was preserved, except for the central scotoma. Case 2 is a healthy 50-year-old man presenting open globe injury with an intraocular metallic foreign body while using a mower. The foreign body damaged the fovea and triggered extensive retinal detachment. One month after surgery, proliferative vitreoretinopathy occurred, requiring additional surgery. The final corrected decimal visual acuity dropped to 0.05, resulting in an extensive visual field defect. Both cases of eye trauma were caused by mower injury, but the visual function outcomes differed with the size of the foreign body and the injury severity at the time of onset. Mower eye trauma is preventable, and efforts to educate users on safety measures are needed.

两例割草机引起中央凹撕裂伤的比较

我们报告并比较了 2 例开放性眼球损伤和割草时发生的中央凹损伤。病例 1 是一名健康的 67 岁男性，使用割草机后出现眼内金属异物和右眼眼痛。异物刺穿角膜下方区域，损伤中央凹中央，导致中央暗点和视力下降。27G玻璃体切除术，最终矫正十进制视力为0.1，但保留视野，除中央暗点外。病例 2 是一名健康的 50 岁男性，在使用割草机时出现眼内金属异物导致眼球开放性损伤。异物损坏了中央凹并引发了广泛的视网膜脱离。手术后 1 个月，发生增殖性玻璃体视网膜病变，需要再次手术。最终矫正十进制视力下降到0.05，导致大范围视野缺损。两例眼外伤均由割草机损伤引起，但视功能结果因异物大小和发病时损伤严重程度而异。割草机眼外伤是可以预防的，需要努力教育用户安全措施。
