Overview

The optical coherence tomography (OCT) and the fundus autofluorescence (FAF) techniques are most often used when diagnosing a genetic variation of retinitis. OCT may be used to acquire in situ retinal imaging for diagnosis of ocular diseases. FAF imaging is a non-invasive technique, dependent on the presence of lipofuscin pigments (lipofuscin is a by-product of lysosomes during the normal process of photoreceptor degradation.)[1]

Imaging Findings

Retinitis pigmentosa

Optical Coherence Tomography

  • An imaging technique used to acquire in situ retinal imaging for diagnosis of ocular diseases.
  • Recent developments have revealed a highly reflective line, identified as the photoreceptor inner and outer segment (IS/OS); crucial for the diagnosis of retinitis pigmentosa.
  • The line is an indicator of a normal alignment of the outer segment's membranous discs in the photoreceptor.
  • The OCT should therefore display a continuous IS/OS line. This line serves as an indicator of good vision, as well as recovery from an invasive, intraocular surgery.[1]
