    6 OCT pitfalls to avoid

    Optometry has widely adopted optical coherence tomography (OCT) as a mainstay in diagnosing and managing ocular disease since its advent in the 1990s. It provides a rapid, noninvasive, and detailed in vivo view of the retinal structure.

    Determining location is critical in the proper diagnosis and management in patients with fluid on OCT.

    Fluid can be found in the intraretinal, subretinal, or subretinal pigment epithelium (RPE) space.

    Intraretinal fluid is seen as rounded, hyporeflective spaces within the layers of the retina and is most commonly a manifestation of diabetes (Figure 1a), retinal vein occlusion, or intraocular inflammation.
