Outer Retinal Tubulation: A Novel Optical Coherence Tomography Finding
Objective To describe tubular structures found in the outer retina seen in a variety of retinal disorders.
Methods Sixty-nine eyes of 63 patients were examined with spectral-domain optical coherence tomography. Optical coherence tomography C-scans were correlated with their corresponding B-scans. The prevalence, number, size, and shape of the tubular structures were determined.
Results Branching tubules were identified in the outer retina of 54 patients with age-related macular degeneration and in 9 patients with other diagnoses. The tubules appeared as round or ovoid hyporeflective spaces with hyperreflective borders on the B-scans, measuring 40 to 140 µm high and 40 to 2260 ...
