各种消费品和玩具可能会导致眼睛受伤。最近，室内遥控(RC)玩具直升机变得非常流行。这项研究的目的是量化与五个商用RC玩具直升机叶片相关的眼睛损伤风险。开发了一个包含25个测试的实验矩阵，在6个人死后的眼睛上测试了5个不同的RC玩具直升机叶片在全电池功率下的性能。通过视神经插入的压力传感器测量了眼压。术后用荧光素染色评估角膜磨损情况。使用已发表的危险函数，眼压与前房积血、晶状体损伤、视网膜损伤和眼球破裂的损伤风险相关。所有检查都导致了角膜擦伤；然而，没有观察到其他损伤。这25项测试产生的眼压在15.2千帕到99.3千帕(114.3毫米汞和744.7毫米汞)之间升高。计算出的刀片速度在16.0m/S到25.4m/S之间。前房积血的损伤风险最大为0.2%。在所有测试中，晶状体损伤、视网膜损伤和眼球破裂的损伤风险为0.0%。叶片的设计参数，如长度和质量，并不影响眼睛受伤的风险。这是第一项量化RC玩具直升机叶片对眼睛伤害风险的研究。虽然观察到了角膜擦伤，但没有观察到也没有预测到会发生更严重的眼部损伤。这项研究的结果对于确定RC玩具直升机叶片的安全设计阈值至关重要，以便防止更严重的伤害。
Eye injuries can be caused by a variety of consumer products and toys. Recently, indoor remote controlled (RC) toy helicopters have become very popular. The purpose of this study is to quantify eye injury risk associated with five commercially available RC toy helicopter blades. An experimental matrix of 25 tests was developed to test five different RC toy helicopter blades at full battery power on six postmortem human eyes. A pressure sensor inserted through the optic nerve measured intraocular pressure. Corneal abrasion was assessed post-impact using fluorescein dye. Intraocular pressure was correlated to injury risk for hyphema, lens damage, retinal damage, and globe rupture using published risk functions. All tests resulted in corneal abrasions; however, no other injuries were observed. The 25 tests produced an increase intraocular pressure between 15.2 kPa and 99.3 kPa (114.3 mmHg and 744.7 mmHg). Calculated blade velocities ranged between 16.0 m/s and 25.4 m/s. Injury risk for hyphema was a maximum of 0.2%. Injury risk for lens damage, retinal damage, and globe rupture was 0.0% for all tests. Blade design parameters such as length and mass did not affect the risk of eye injury. This is the first study to quantify the risk of eye injury from RC toy helicopter blades. While corneal abrasions were observed, more serious eye injuries were neither observed nor predicted to have occurred. Results from this study are critical for establishing safe design thresholds for RC toy helicopter blades so that more serious injuries can be prevented.
