Speleological exploration of the posterior pole
Blocks of tightly spaced OCT B-scans can be made in very short time with swept-source instruments for fundus examination. The features of the retina are shown to advantage in three-dimensional projections that can be rotated and cropped by the user. Such displays are particularly informative when large, optically empty spaces are present in the field of view. This is seen in cystoid macular edema, serous detachment of the retina or the pigment epithelium, neovascular and drusenoid detachments, choroidal lacunae, etc. Techniques of recording and display as well as selected cases will be used to demonstrate the scope of this attractive method of OCT-scanning and analyzing the retina in various eye diseases.
