OCT is useful in the diagnosis of many retinal conditions, especially when the media is clear. OCT can be particularly helpful in diagnosing the below pathologies:
Macular pucker/epiretinal membrane
Macular edema and exudates
Detachments of the neurosensory retina
Detachments of the retinal pigment epithelium (e.g., central serous chorio-retinopathy or age-related macular degeneration)
In some cases, OCT alone may yield the diagnosis (e.g., macular hole). Yet, in other disorders, especially retinal vascular disorders, it may be helpful to order additional tests (e.g., Fluorescein Angiography or Indocyanine Green Angiography).
