High-Resolution Oct Findings in Traumatic Maculopathy

Abstract

Purpose:: To describe the high-resolution Fourier-domain optical coherence tomographic findings among patients with vision loss after traumatic maculopathy.

Methods:: Five patients with history of traumatic maculopathy were scanned using the Fourier-domain OCT device constructed at UC Davis. The FD OCT instrument used in this study achieves high axial resolution of 3.5 microns, transverse resolution between 10-15 microns, high acquisition speeds (10,000 A-scans/frame, 9 frames/second) and real time display at the same rate. the FD OCT findings were correlated with fundus appearance.

Results:: High-resolution FD OCT detected focal disruptions in the photoreceptor layer and abnormalities in other outer retinal layers even when fundus appearance and fluorescein angiography findings were minimal. These morphological changes may result in vision loss that may be unexplained on routine clinical evaluation.

Conclusions:: Patients with history of traumatic maculopathy can have outer retinal changes which may result in vision loss that cannot be explained on routine clinical evaluation.
