【 摘 要 】

Purpose: To describe two cases of Purtscher-like retinopathy after total knee arthroplasty. Observations: Two patients were referred for blurred vision after knee surgery. They received a complete vision examination including slit lamp exam, dilated fundus exam, fluorescein angiogram and optical coherence tomography. Two patients developed Purtscher-like retinopathy after knee surgery. The first was a 58-year-old male who underwent bilateral total knee arthroplasty. The second patient developed an infected joint and subsequently received a total knee arthroplasty revision surgery. Both patients experienced decreased vision and were found to have characteristic findings of Purtscher-like retinopathy including vessel attenuation, cotton wool spots and nerve fiber layer infarcts following their respective operations in the absence of other injury. Conclusions and Importance: Purtscher-like retinopathy can occur immediately following total knee arthroplasty. Factors including fatty acid liberation, endothelial damage, aberrant coagulation cascade activation, leukocyte aggregation, embolic vascular occlusion and microinfarction likely contributed to these findings. When patients undergo knee arthroplasty and complain of visual scotomas, the diagnosis of Purtscher-like retinopathy should be considered with careful ophthalmic examination and work-up.
