The purpose of this research is to study the intraocular occurrence of SARS-CoV-2. In postmortem examinations, aqueous humor and the vitreous samples were collected. All individuals were previously positive in nasopharyngeal swabbing and cause of death was respiratory failure due to SARS-CoV-2 infection. Testing was done using quantitative RT-PCR. We included 16 aqueous humor and 16 vitreous samples for PCR testing. None of the results was positive for SARS-CoV-2. Human GAPDH genes to verify the presence of RNA was present in all aqueous humor samples (16/16, 100%) and 15/16 (93.8%) vitreous samples. In conclusion, this case series found no evidence of SARS-CoV-2 in the intraocular milieu.
本研究旨在研究 SARS-CoV-2 在眼内的发生情况。在尸检中，收集了房水和玻璃体样本。所有个体的鼻咽拭子先前均为阳性，死亡原因是 SARS-CoV-2 感染引起的呼吸衰竭。检测使用定量 RT-PCR 进行。我们纳入了 16 份房水和 16 份玻璃体样本进行 PCR 检测。SARS-CoV-2 的检测结果均为阴性。所有房水样本（16/16，100%）和 15/16（93.8%）玻璃体样本中均存在人 GAPDH 基因以验证 RNA 的存在。总之，本病例系列研究未发现眼内环境中有 SARS-CoV-2 的证据。
