Combat sports, some of the earliest forms of entertainment, competition, and conflict resolution, encompass a variety of activities that often include physical confrontation. These sports are typically divided into four primary categories: striking, grappling, weapon-based, and hybrid, each governed by its own set of rules. In essence, combat sports involve two competitors striving to outmatch each other through physical contact, while adhering to specific regulations. Consequently, injuries are frequent, ranging from cuts and abrasions to fractures, muscle strains, neurological and eye injuries, with severe cases potentially leading to fatal outcomes. Understanding how the visual system is engaged and at risk in combat sports is also critical, as it greatly influences an athlete’s performance and susceptibility to ocular injuries. The eye, due to its anatomy, is particularly vulnerable to various forms of injury, carrying a significant risk of permanent damage. Recognizing the types of injuries prevalent in each combat sport category is crucial for timely diagnosis and treatment, helping to minimize long-term harm. Furthermore, understanding these injuries is essential for developing rules and regulations aimed at reducing their occurrence.
