Optical coherence tomography patterns and outcomes of contusion maculopathy caused by impact of sporting equipment.

ABSTRACT

BACKGROUND: To describe the patterns and outcomes of contusion maculopathy after ocular contusions resulting from accidental impact with sporting equipment. METHODS: We conducted a retrospective study of interventional case series. PATIENT POPULATION Twenty-one eyes of 21 patients who sustained blunt ocular trauma while playing a sport. Intervention/Observation Procedure(s) Surgery or observation by optical coherence tomography (OCT). MAIN OUTCOME MEASURE(S) The morphologic changes within the macula in the early stages after injury and changes in visual function in the early and recovery stages after injury. RESULTS: In the early stage, OCT visualized four injury patterns type Ι, commotio retinae (14.3%, 3 eyes) with increased reflectivity of the ellipsoid zone and retinal pigment epithelium; type II, incomplete macular hole(38.1%, 8 eyes) with three structural changes, i.e., a partial V-shaped macular hole, a jar-shaped macular hole with retinal tissue at the bottom, and a connective bridge attached to retinal tissues; type III, full-thickness macular hole (33.3%, 7 eyes); and type IV, foveal hemorrhage (14.3%, 3 eyes). During recovery, OCT images of types Ι and II showed almost normal macular morphology with better visual acuity (mean ± SD,0.02 ± 0.1 and 0.14 ± 0.21logMAR.). In types III and IV, the visual prognosis was poor (0.52 ± 0.34 and 0.22 ± 0.16), OCT images showed retinal atrophy at the fovea despite vitrectomy and sulfur hexafluoride (SF6) gas tamponade. CONCLUSION: Early OCT images identified four patterns of contusion maculopathy with different treatment outcomes. In types Ι and II, the visual function and retinal morphology remained intact. With types III and IV, respectively, the treatments of vitrectomy and SF6 gas tamponade for patients were effective.
