Customized Face Guards as Protective Devices for Ocular Trauma in Futsal Players: A Case Report and Clinical Efficacy Evaluation

We present a case involving a futsal player with brain concussions and commotio retinae to protect the affected area and support a safe, prompt return to play custom face guard instead of a commercial face guard and sports goggles. For a better fit, we fabricated a custom face guard, for which a facial impression was taken using dental alginate material and plaster in July 2019. The following month, the custom face guard was set on the player's face so that its outline provided minimal coverage of the nose area compared with a conventional face guard. The field of view during play and the guard's protectiveness were tested by confirming that the ball did not strike the player's eyes. This is a rare case involving face guard use for eye injury prevention. The findings suggest that a custom face guard may be employed as a preventive measure for futsal-related eye injuries.
