Complimentary imaging technologies in blunt ocular trauma

ABSTRACT

We describe complimentary imaging technologies in traumatic chorioretinal injury. Color and fundus autofluorescence [FAF] images were obtained with a non-mydriatic retinal camera. Optical coherence tomography [OCT] helped obtain detailed images of retinal structure. Microperimetry was used to evaluate the visual function. A 40-year-old man sustained blunt ocular trauma with a stone. Color fundus image showed a large chorioretinal scar in the macula. Software filters allowed detailed illustration of extensive macular fibrosis. A 58-year-old man presented with blunt force trauma with a tennis ball. Color fundus imaging showed a crescentric area of macular choroidal rupture with fibrosis. FAF imaging delineated an area of hypofluorescence greater on fundus imaging. OCT showed chorioretinal atrophy in the macula. Microperimetry delineated an absolute scotoma with no response to maximal stimuli. Fundus imaging with digital filters and FAF illustrated the full extent of chorioretinal injury, while OCT and microperimetry corroborated the structure and function correlations.
