Abstract
Using an advanced prototype of en-face OCT/cSLO instrument, an extensive array of clinic pathologies were studied including macular degeneration, central serous retinopathy (CSR), macular hole, macular pucker, cystoid macular edema (CME), diabetic maculopathy, and macular trauma. We report observation of reoccurring patterns in the en-face OCT images which could be identified with different diseases. Uniquely specific and reoccurring patterns could be characterized for macular hole ("Chrysanthemum flower"), CME ("Swiss cheese wheel"), Macular Pucker ("Star"), CSR ("Target") and RPE Detachment ("Ring of Light"). Other entities such as polypoidal choroidopathy and diabetic edema residues had easily recognizable features but were variable enough to defy specific descriptive comparison. To facilitate the interpretation of the en-face OCT images, a three dimensional interactive simulation was designed which allows the demonstration of characteristic features and artifacts encountered in the acquisition of transverse images.
