Complimentary imaging technologies in blunt ocular trauma
A 40-year-old African American man presented with a past ocular history of blunt force trauma with a projectile object (stone) at age nine. No surgical intervention was recommended at that time. Vision deteriorated to counting fingers (CF) within a few weeks. At the screening examination, uncorrected visual acuity (VA) was 20/30 and CF, and IOP was 14 mm Hg and 22 mm Hg in the right and left eyes, respectively. FDT visual field testing showed a central scotoma.\nThe right eye fundus imaging was within the normal limits (not shown). Color fundus photo of the affected left eye showed an approximately two-disc diameter chorioretinal scar in the macular region []. Image analysis was then performed using the digital red wavelength filter (610 nm) to better illustrate outer retinal pathology (including the retinal pigment epithelium [RPE] and choroidal findings) and showed extensive fibrosis and macular hypopigmentation []. A topographical monochromatic filter created an “embossed” image of retinal elevations and depressions that highlighted topographic macular changes []. Both images illustrated extensive fibrosis in the macula. The subject declined further evaluation with FAF and OCT or microperimetry for a more detailed assessment of the visual field.
