Summary

Outer retinal tubulation, a new term for tubular structures in degenerating photoreceptors, is common in advanced retinal diseases. These findings in optical coherence tomography scans can be mistaken for fluid, leading to unnecessary treatments.

Area of Science:

  • Ophthalmology
  • Retinal Imaging
  • Pathology

Background:

  • Spectral-domain optical coherence tomography (SD-OCT) is crucial for diagnosing retinal disorders.
  • Understanding structural changes in the outer retina is key to managing diseases like age-related macular degeneration (AMD).

Observation:

  • Tubular structures were identified in the outer retina of patients with various retinal disorders, particularly advanced AMD.
  • These tubules appeared as hyporeflective spaces with hyperreflective borders on SD-OCT B-scans.

Findings:

  • The prevalence of outer retinal tubulation was 24.2% in a specialized retinal practice.
  • Morphologically, these ranged from simple tubules to complex networks, often associated with pigment epithelial changes or fibrosis.
  • The structures were generally stable over time.

Implications:

  • Outer retinal tubulation may represent degenerating photoreceptors arranged in a specific pattern.
  • Accurate identification is crucial to avoid misinterpretation as intraretinal or subretinal fluid.
  • This can prevent unnecessary interventions and guide appropriate patient management.
